Corrugated board: sizes, technical characteristics, types and types of profiled sheets

Because of its strength and adaptability, corrugated board is a common material for building cladding and roofing. This kind of material is available in a range of sizes and profiles, each created to meet specific functional and architectural needs. Corrugated board provides a variety of options to meet your needs, whether you’re looking for a solution for agricultural structures, commercial buildings, or residential homes.

The profiled structure of corrugated board is one of its distinguishing qualities; it reduces overall weight while improving strength. This design enhances the material’s resistance to weathering and structural loads while also simplifying installation. Usually composed of metals like aluminum, galvanized steel, or other alloys, the sheets offer strength and resistance to rust.

Corrugated board sizes can change based on the manufacturer and intended use. Standard lengths of 6 to 12 feet are among the common dimensions, and there are widths to suit different requirements for coverage. These measurements provide flexibility in both design and installation, enabling homeowners and builders to modify the material to suit varying architectural styles and roof pitches.

The technical properties of corrugated board are important in determining whether or not it is appropriate for a given project. The material’s load-bearing capacity, impact resistance, and thermal performance are influenced by variables like gauge thickness, rib height, and overall profile shape. Comprehending these technical aspects aids in selecting the appropriate corrugated board type to guarantee durability and effectiveness in construction projects.

What are the profileized sheets?

Today, precisely profiled and flat sheets present the widest selection of technical metal sheets.

One of the greatest materials for low-rise building is this one, as it is incredibly appropriate for the roof as well as for building fences, ceilings, and wall cladding:

A modern professional sheet is based on a thin-leaved rental with an aluminum or zinc coating, and it is manufactured using two distinct technologies: TU 14-11-247-88 (AC) and TU 14-11-236-88.

Advantages of corrugated board over other materials

Corrugated board and profiled sheets, also known as profiled flooring, are sheets with corrugated profiles and corrugated corrugators in different shapes. They are made by cold basting a thin sheet of cold-rolled steel.

For this reason, the coating is referred to as a multifunctional building material. It all comes down to various types that vary in metal thickness, profile shape, and use. The profiled sheet’s width ranges from 600 mm to 1150 mm, and the metal’s thickness varies from 0.35 to 0.9 mm. A unique marking on the package indicates that the waves are made between 20 and 130 mm in height in the factory. The length of the sheet is frequently longer than what the customer specifically requests or what a particular manufacturer prefers.

They appreciate these attributes in a roof:

• Ease. The weight of a square meter of corrugated board is from 3.9 kg to 24.1 kg. Thanks to this, it is possible to significantly reduce the volume of supporting structures, and there is no need for serious support.
• Anti -corrosion protection and the possibility of decorative coating. The best products from leading manufacturers have a 45 -year service life.
• The possibility of multiple use, which cannot be said about the soft roof.
• Large selection of fasteners and their colors.
• Location of mechanical processing. The corrugated board is cut and drilled with ordinary building tools.

By the way, corrugated board is often compared with metal tiles as a material similar in terms of manufacturing and operation. The same basis, the same cold press, only the view of the other. In fact, there is a huge difference between them! It"s all about the so-called "dead zones" of the metal tile, because of which it is difficult to cut. For example, if you do not order a cutting of coating in the factory according to a certain project in advance, then you cannot avoid a large overspending. In addition, individual pieces of metal tiles are quite difficult to join among themselves in order to achieve an even and sealed seam, but with the corrugated board everything is much easier.

Last but not least, this type of roofing has outstanding bending stiffness and mechanical strength along the corrugation. And it’s not hyperbole to say that having these technological advantages enables you to construct sturdy, safe buildings. As a result, we will list corrugated board’s three primary characteristics: environmental friendliness, fire safety, and durability.

Additionally, because of its affordability, simplicity, and ease of installation, the locals value this material for private construction. Examining from the perspective of the practice, the sheets are lightweight, cozy, simple to transport and store, and can be easily cut with standard metal scissors. Installation of corrugated roofing can be handled by any home master; just visit our website for helpful tips. Furthermore, it is simple to replace individual pieces of corrugated board during the process of repairing the coating, and you can even reuse the old pieces for the new roof.

On this subject, here’s a cognitive video clock:

Additional coating and protection against corrosion

The process of creating modern corrugated board involves cold rolling premium galvanized steel. Here, zinc is essential because it provides good protection against environmental influences; however, polymer coatings are also required to preserve zinc. In addition to giving it a beautiful look, contemporary coatings greatly enhance its mechanical indicators, offer durability, and guard against atmospheric influences.

In essence, this is either aluminum-fasteners, when the leaf is coated with a zinc and aluminum mixture, or galvanizing, which offers exceptional corrosion protection. Although less durable, this coating option is more affordable. The truth is that corrugated board’s protective qualities are diminished by inexpensive aluminum. For this reason, additional decorative material, like polyester, is applied on top of these sheets.

Furthermore, the least expensive corrugated board, which is frequently seen on the home market, is not colored at all during production. Not only does he look unprofessional, but the content is also of poor quality. However, low cost is more important than aesthetics when creating an overlap for large areas. This option differs slightly from the galvanizing with silicon addition, but it is still superior.

Corrugated board is made by applying a unique polymer coating. After all, if left uncovered, a galvanized sheet will corrode and wear out quickly, requiring frequent cleaning. This is not an option for the roof, so it is preferable to use profiles with an outer layer of purl and other similar coatings.

In addition to being a matter of taste, the coating’s color is significant for designers. An industrial building, for instance, needs to remain in the corporate style selected. Furthermore, the species of the color polymer coating are:

• Glossy polyester, which looks great and protects well from corrosion. It is often used for corrugated board of external wall decoration and facade. Polyester is enough for it to resist the occurrence of corrosion and it is not necessary to have racks of mechanical damage, which are few there. Therefore, such profiled sheets are often ordered for industrial buildings, which usually have more than one floor. But if you choose corrugated board for decorating your own home, think that the winds and other garbage will be spread by the wind, and therefore scratches are more likely and you should not save.
• Pural – more expensive coating. It is made on the basis of polyurethane and polyamide. Provides high reliability and remarkable resistance to ultraviolet radiation and low temperatures. For roofing corrugated board it is better not to find.
• Plastic – The most durable of all types of coating, 200 μm thick. It is based on polyvinyl chloride, and in the factory, relief embossing with a notch is applied to such a coating, for especially difficult climatic conditions.

Though they have their own benefits, coatings like acrylic, PVC (polyvinyl chloride), and PVDF are less frequently found on corrugated board.

When discussing the roof, the zinc coating’s thickness and application technique are very important. If this is insufficient, any scuffs on the roof will cause corrosion to happen quickly. The kind of rental is also significant because it influences how long the new roof will last:

Huffra"s stiffness requirements and shape

These days, corrugated board comes in a variety of sheet and profiling form sizes. Choosing corrugated board for a roof is straightforward. Just apply the basic rule that stronger roofing corresponds with more corrugation.

However, if you approach the situation responsibly, figure out the future roof’s load first, and only then determine how closely the chosen metal thickness and profiling height match these parameters.

Thus, corrugated board with this type of corrugation is released today:

1. Wavy, which has a cross section in the form of a sinusoid. The wavy shape is the earliest, it appeared at the end of the XIX century. Such a roof from corrugated board has a particularly aesthetic appearance, which is so appreciated by designers. The waves themselves are sinusoids or more complex in form mating circles.
2. Trapezoidal, which provides the corrugated board with maximum stiffness and bearing capacity. This form of a metal rolling sheet appeared in the 20s of the 20th century. The profile in the form of a trapezoid was in practice more durable, with a high bearing capacity and ease of installation. And until today it is the most popular form of corrugated board, which is produced with a corrugation height from 2 to 208 mm.
3. Cassette, With the cross -section and shape of the corrugation, the form of the letter “P”, which is wonderful for strengthening wall structures. Profileists with this form appeared relatively recently and are designed specifically for use in wall structures.

Observe how these varieties differ visually:

Corrugated board profiles vary in height as well, measuring 12, 14, 18, 20, 30, 35, and even 65 mm. The height of the corrugated board’s profile is stated on the packaging. The strictness and height of the sheets are the primary requirements for this parameter. The secret is that the corrugated board itself will be tougher the higher the profile. However, residential buildings are more likely to use a low profile, up to 12 mm.

It may interest you to know that there is a specific relationship between the height of the corrugation, the profile, and the sheet size in corrugated board. For instance, sheets measuring 30-55 mm in height have a thickness of 0.25 to 0.5 mm, while sheets measuring 12-20 mm in height have a thickness of 0.5 mm.

Finally, the existence of grooves is another way that corrugated board varies. For instance, if the overlapped sheets have a capillary groove, it should be positioned beneath the sheet; this is an extra measure that will aid in removing moisture from the roof.

Types of corrugated board: wall, carrying or roofing

Contemporary corrugated board is highly valued in rapid technologies and is in high demand in architecture and construction. It is employed not only for roof arrangement but also for wall and facade decoration, among other things. A professional like this is more subtle than is strictly needed to cover the roof.

For this reason, it’s critical to comprehend his types:

When examining the specific applications of corrugated board, the following areas come to mind:

1. Wall corrugated board used for wall lining and cladding of various fences. Usually the profiling height is no more than 20 mm.
2. Roofing corrugated board Designed to cover the roof, from simple to complex shapes. Standard corrugation height-20-45 millimeters.
3. Carrying corrugated board With a height of 45-160 mm, it is produced specifically to create ceilings of warehouse and industrial facilities.

The wall cornfield is denoted by the letter "C," the roofing by the letter "SN" or a different abbreviation that carries the letter "H," and there is still a different type of corrugated board with a trapezoidal form, which is denoted by the letter "T" to avoid confusion among buyers.

The height of the profile is indicated by the figure that will appear next to the main letter, though some manufacturers may also include information about the metal’s thickness, type of coating, and brand:

Let’s examine each species in isolation.

Wall corrugated board: lightness and stiffness

All profiles with a wave-like and trapezoidal form, ranging in height from 8 to 44 mm, are now denoted by the letter "C." Utilize these profiles for sandwich panels, wall fences, walls, and fences. The C-profile serves primarily as a decorative and protective element.

C8 is decorative corrugated board for walls. Its 8 mm high profile—which is thought to be the best relief for the cladding—is the result of its short repeatability period. Furthermore, the small radius of the leaf bunch and the higher inclination of the side shelves give the sheet its stiffness rather than the profile’s shape. T6 and T8, the equivalents in Europe.

C10 is already listed among the profiled sheets that are part of GOST 24045-94. Unusual blanks with a parameter of 1250 mm are used in place of standard blanks with a width of 1000 and 1100 mm for the manufacture of this type. As a result, sheets with a thickness of 0.35 to 0.8 mm are produced. For fences, C10 is more frequently utilized to mimic the look of wood and other contemporary design concepts. Additionally, C10—Basic sandwich panel material.

C13: The walls and roof are made of thin-leaf galvanized steel. Corrugated board finds widespread application in prefabricated panels, fences, cladding, and building constructions. Furthermore, the fence can already be erected above 2.5 meters because of its increased hardness. Such sheets have a working installation width of 1100 mm. Additionally, coloring the polymer on both sides is already permitted in this instance. European counterparts: RAN-15, T14, and C15.

C17 is a more resilient profile for roofs and fences that is also used for lightning and fire protection fencing, as well as internal and external cladding on metal buildings. Another way that this profileist varies from earlier choices is that it has a water-flow groove that inadvertently seeps into the seam between adjacent sheets. Installation width: 1090 mm for C17. Profiled sheets C17, 18, and 20 have European equivalents: T18 and T20, RAN-20, MP20.

While such roofing looks fantastic on a straightforward slope, there are certain limitations: the minimum inclination angle should be 14 degrees, except for certain corrugated board types where 8 or 9 degrees are acceptable. Additionally, a specific corrugated board with a 3–4 degree slope is available for nearly flat roofs.

C18 is essentially premium corrugated board with tiny stiffeners. They remove the primary flaw that most metal roofs have, which is that each wind gust causes a flat sheet to clap. In order to achieve this, a tight sealing of narrow corrugations and great jokes were overlapped with this kind of metal profile. A groove for moisture drainage is present. Width of mounting: 1150 mm. Finnish profiles RAN-19R and Orion serve as an analog.

An additional view of C18 – C18 (wave). This profile is wavy, as you have probably already surmised. He gains a large bending radius and an excessive amount of stiffness as a result. As a result, the maximum mounting area is limited to 1100 mm. B18-1000, A18-1000, MP 18, and RAN-18R are the analogs.

C20 is a marginally better choice than the preceding one. Comparators: RAN-20 and T20.

C21: This wall profile is in line with GOST 24045-94. Like honeycombs, he has the proper trapezoidal structure. It provides a product that is high-quality and useful for everyone. Maximum installation width of 1000 mm.

One of the most widely used metal profiles for roofs, walls, and fences is NS35. The stiffeners in this instance are 7 mm deep. As a result, a profile of this kind can be used to arrange coating with a crate as large as 1.5 meters and non-removable formwork.

NS44 as well as for fences, walls, and coatings. It is constructed from a sheet that is 1400 mm wide and, in terms of strength, is equivalent to the 750 mm wide profiled sheet H114. Apply this coating up to 2.5 meters in one step of the crate.

Another choice is NS44 TU, which mimics its analogue NS44-1000 and has stiffeners on both wide and narrow shelves for external resemblances. However, in this case, the workpiece’s width is smaller, resulting in a reduction of the profile periods from five to four, a decrease in the side shelves’ angle of inclination, and dimensions that are both wide and narrow.

C44 The manufacture follows GOST 24045-94. The relief lines appear clean and uncomplicated, and there are no extra stiffener ribs. This type of profile, which has an installation width of 1000 mm, is used for wall cladding, roofing, and walls. Such sheets can be placed on a two-meter-step crate.

Non-level-wall profile: Borderline values

A different kind of corrugated board with the designation "NS" To a certain degree, they are weak enough to be used as flooring and too good for standard wall décor. However, in many domains, such as high continuous fences, wall fences, and even certain roofs, they are absolutely essential.

H750: Corrugated board conductivity. Given that it is a part of GOST 24045-94, even novice designers can utilize it with success. This species’ sole disadvantage is that it lacks the 1100 mm roll blank that it requires.

H900 is a more robust sheet metal profile that is currently produced by plants based on their technical specifications. As long as the crate step is laid out no more than three meters, it is acceptable.

Carrying corrugation: strength and thickness

Profiled sheets with 57 mm of corrugation are used in the construction of the interstory ceiling designs. When spans exceed three meters, corrugation between 57 and 75 mm is selected; if spans exceed three meters, corrugated board thickness ranges from 0.7 to 0.8 mm. There are corrugated boards like this with extra stiffener ribs for greater bearing capacity.

When building multi-story floors, non-removable formwork reinforcement, support, and obviously roofing are all done with corrugated board. These sheets are additionally employed as a component of the building’s or house’s supporting framework:

H60: bent sheet corners for metal roof arrangement, non-removable formwork, and supporting structures beneath soft roofs. The foundation is a 1250 mm wide galvanized sheet with a minimum rental brand of 220. It’s also mounted on supports that are no broader than three meters. GOST-24045-94. Today, its analogue, which is made of structural workpieces, is used in place of the less dependable N57-750.

The corrugated board H75 is the most widely used type and is actively used in steel design for all climate zones. Even on a crate that is set up in steps up to 4.5 meters, it can be placed! And in accordance with GOST 52246-2004, they make it H75 From rolled rental of brand 220-350.

H114 is a metal profile that is utilized for overlap. Among other steel flooring, it has the largest bearing capacity, measuring 600 mm H114 in width. It is made of steel that is 1250 mm wide and 0.7–1.0 m thick. Ideal for formwork that is not removable.

His subrace H114 750 It greatly restricts the use of such corrugated board with a blank width of 1400 mm and greatly expands the overlap width with a single sheet compared to H114-600. Further information is available at H114, the highest trapezoidal corrugation, the parameters of which establish the GOST 24045-94 standard. Because of this, such sheets have already been installed with up to a 6-meter step of supports. H114-RAN-113 analog.

H153 – Also known as "Europrofil," this is a supporting professionalist of European caliber. He is allowed to go up to nine meters in the crate! Because of this, it is utilized for both the roof and the layout of multi-story floors, as well as in situations where the maximum bearing capacity is required without significantly increasing the weight of the entire structure. Analogs include RAN-153, which is only made in white, and T150.1.

H158: Made in Russia, this is the strongest and highest grade Europrofille. It is made in compliance with European standards. H158 750 – T.160.1’s analog.

There are two subspecies of carrying corrugated board, by the way: supporting and self-supporting. Large industrial facilities use the self-supporter, while pools in other private construction projects require the carrier.

Recognized for its resilience and adaptability, corrugated metal roofing is available in a range of shapes and sizes to meet diverse building requirements. Because of its lightweight design and resistance to different weather conditions, it provides a useful option for both residential and commercial buildings.

The variety of sizes available in corrugated board makes it a valuable material for a variety of roofing applications. There’s a size for practically any need, from big industrial complexes to smaller residential roofs. Because of their adaptability, corrugated sheets are a popular option for both homeowners and builders.

When evaluating corrugated metal’s suitability for roofing, technical features are very important. Usually, galvanized steel or aluminum are used to make these sheets, which improves their resistance to corrosion. Because of their durability, they will last longer than conventional roofing materials, which means that they will end up being a more economical investment over time.

The design and application of profiled sheets determine their various types. For example, because of their visual appeal, sinusoidal roof profiles are frequently used for residential buildings, whereas trapezoidal profiles are more favored for industrial buildings because of their durability and effectiveness in shedding water. Knowing these kinds makes it easier to choose the ideal profile for a given set of functional and architectural requirements.

To sum up, corrugated metal roofing is unique due to its versatility, toughness, and abundance of choices. Whether you’re planning a new building project or replacing an old roof, corrugated sheets can offer both practical advantages and visual appeal, guaranteeing a sturdy and long-lasting roofing solution.

We examine the different sizes, technical characteristics, and kinds of profiled sheets that are available for corrugated board. In order to enable readers to make wise decisions for their building and roofing projects, this thorough guide seeks to demystify the options by providing clarity on how these sheets differ in design and functionality."
