Profilets consumption of 1 m2 of roof coefficient

Anyone working on roofing projects needs to be aware of the profiled sheet consumption per square meter of roof area. This coefficient, which is sometimes just called coverage or yield, establishes the number of profiled metal sheets required to cover a specific roof area. This is a basic computation that affects the price of materials, the duration of projects, and overall productivity.

There are multiple factors that influence the consumption of profiled sheets per square meter. First and foremost, the kind and dimensions of the profiled sheet itself are important. Each profiled sheet has a distinct coverage area and is available in a variety of sizes and shapes. Second, the way the sheets overlap and are arranged influences the overall area that each sheet effectively covers. This is due to the pitch or slope of the roof.

Basic math is required to calculate the profiled sheet consumption. You can calculate the total number of sheets needed for the project by multiplying the number of sheets needed to cover one square meter by the roof’s total area. This computation guarantees that the right quantity of materials are ordered, reducing waste and preventing delays brought on by a shortage.

Comprehending and precisely computing profiled sheet consumption is crucial for both novice and expert roofers to efficiently plan and carry out roofing projects. Comprehending this coefficient is crucial for maintaining project timeliness and financial constraints, regardless of whether you’re building a new roof or replacing an existing one.

Roof Profile Type	Coefficient of Profile Consumption per 1 m²
Metal Sheet (Corrugated)	1.2 units
Clay Tile	1.5 units

"Knowing the amount of profilets used per square meter of roof requires using the coefficient. In essence, this coefficient expresses the amount of profilet material required to cover one square meter of roof surface. It has an immediate effect on roof installation costs and efficiency, influencing decisions about material usage and budgeting. Roofing specialists can optimize their material orders, reduce waste, and guarantee accurate project estimates by precisely calculating this coefficient. This article examines the profilet consumption coefficient’s importance, computation techniques, and useful applications for roofing projects."

Fastening of profiled flooring and calculation of self -tapping screws

During the roof installation process, we all had questions about profiled flooring (corrugated board) and how many screws were needed to fix it correctly. We also had questions about how many self-tapping screws were needed for every one meter two of profiled sheets and how to choose them.

Self-tapping screws are used in the roof-mounted farm mounting scheme. When installing a fence, five to six screws are required for every square meter of coating; for a roof, six to eight screws are needed.

For optimal adhesion and to prevent unintended consequences, the profiled sheet’s thickness and dimensions must be considered when fastening. This article will examine how to accurately determine the quantity of screws needed and which professionals should use them.

The right length must be chosen when arranging roofs with profiled flooring so that it is greater than the slope of the roof. Self-cutting screws are used to secure the corrugated board to the wooden crate. Because the screws drill metal when they are in place, you can alternatively use a metal crate. Metizes made by Hilli, EKT, SFS, and FISCher should be used for the roof; their diameters should be 4, 8, 5.5, and 6.3 mm, and their lengths should range from 19 to 250 mm. Additionally, you can purchase goods made in your country that have a minimum diameter of 6.3 mm.

The screws and quantity chosen for the roof are chosen so that the threaded portion of the screw is at least 3 mm longer than the length of the connected package.

When purchasing self-tapping screws, you must consider both their quality and quantity with a margin. The pre-drilled holes can be removed before installing premium screws. Both the inside and outside walls of the building and its roof are made of corrugated board, and their attachment is done correctly by calculating the quantity needed.

Corrugated board comes in three primary varieties that are commonly used:

The roofing is used for the roof and has a higher height. Wall: less volumetric. Carrying: Because of its thickness, it is used to support structures. Simultaneously, the forms are entirely distinct and necessitate a unique method of attachment.

Rules for fastening corrugated board

An illustration of how self-tapping screws should be screwed. Controlling the force is essential when manually tightening to prevent the tug from working, which carries a risk of damaging the insulating layer.

For fastening, a properly prepared surface must be present. The corrugated board is attached at the place of fit to the crate of the wave of the trapezoid of the profiled sheet. In this method, there is no lever between the point of imposition of efforts on the self -tapping screw and the mounting point. To decrease the wind loads of each wave of the trapezoid, the corrugated board is attached to the lower and upper collapse, and from the side of the wind bar is attached to each collapse. Profiled flooring with a width of 1100 mm and a length of 8000 mm with a crate of 500 mm requires a distance between self -tapping screws of not more than 500 mm. Conclusion: at the top 2 self -tapping screws, from below 2, plus the wind side – 16 pieces. Total we need 20 self -tapping screws per 1 sheet of material. Before installation in the profiled sheet, a hole is drilled 0.3-0.5 mm larger than the diameter of the screw. Screwing screws are made at an angle of 90 degrees. This is necessary to eliminate the possible appearance of through holes in the roof.

Drill – only at low speed of the cartridge.
Screwdriver is a simple and reliable manual way.

Any other or all of these tool use demands a high level of expertise and adherence to safety protocols.

The laying of corrugated board with a thickness of 0.5 to 1 mm and a length of 2 to 12 meters begins at the right or left end. At the edges, the profile should be 40 cm. The first profile we install and fasten with one screw for the horse. After we fasten the second on one screw to the skate. All the time we make sure that the edges of the sheets lie on the same line and the profile does not skew. At the top of the wave we fasten the overlap of sheets with one screw. Thus we fasten the other three sheets. After leveling their lower edge, we firmly fasten them along the entire length. Horizontal overlap of sheets is allowed from 10 cm. Thus, 1 m2 is consumed from 4 to 8 screws.

Features of the installation of wall corrugated board

Its installation to the wall begins with the right corner. Before installing on the wall, you need to check the surface for irregularities. After we fasten the wooden crate or rigel. To ensure a good fit of the sheet and good mount, the distance of the crossbar controls. It should be about 0.5 mm. The subsequent profile is attached to the previous one with an overlap. Thus, they cover the capillary groove of the first profiled sheet. When working, careful control is required to avoid distortion. Below you need to leave a gap from 2 to 4 cm for ventilation of space under the corrugated board. If desired, they are filled with thermal insulation or sound insulation the space between the profiled sheet and the crate. We start the security for the corner and go to the top. During fastening, you need to leave a minimum of distance between self -tapping screws and the supporting structure. With a profiled sheet of 1250 mm wide and 10,000 mm long, 45 self -tapping screws are required. On average, the profile 1 m 2 requires from 5 to 8 pieces.

Here is another way to calculate the number of self -tapping screws for attaching a profiled sheet

The corrugated board layout is taken. Consider a profile that is 12,200 mm long and 1000 mm wide. To prevent errors, you must be certain of the data in each situation. Each wave’s extreme supports are where the profile is fastened, and it passes through one wave to the intermediate. The sheets are fastened together by self-tapping screws, spaced one meter apart from the support and measuring 250, 500, and 1000 mm in increments. Add extreme metizes, multiply the number of sheets, and multiply the percentage per marriage. We figure out the lower screws. In total, there are 6–9 pieces per square meter.

Corporate storage rates – what needs to be taken into account when calculating?

Traditionally, corrugated board has been utilized for wall construction, facing facades, and roofing. Profiled sheets have become increasingly popular as building materials for different types of fences in recent years.

However, regardless of the intended use of the profiled sheet, it is always important to ascertain how much corrugated board will be used in a square meter for the roof, facade, or fence.

Scheme for calculating the corrugated board consumption rate per sheet

There isn’t a set standard rate of corrugated board consumption in the construction industry. A profiled sheet’s consumption for one square meter is dependent on numerous variables. When designing individually for each design, the norms of consumption of a profiled sheet are established, considering the technical and individual characteristics of each design.

The norms of consumption of a profiled sheet during the installation of the roofing

Tightness is the most crucial feature of any roofing material. Neither during the strongest downpours or snowfalls nor during the springtime melting of snow should water enter the undercarbon space.

However, the corrugated board should be installed so that the least amount of rainwater falls on the building’s facade, protecting not just the attic but also the attic itself. Therefore, there are a few fundamental guidelines that need to be followed when installing corrugated board.

Vertical overlap

First and foremost, it is important to remember that profiled sheets need to overlap one another when being laid on the roof. Furthermore, the overlap is carried out between adjacent sheets as well as between the corrugated board’s upper and lower rows. The amount of corrugated board used on the roof varies with the size of the overlap.

The amount of corrugated board needed to cover a square meter of roof, accounting for vertical overlap

The roof’s slope determines how much of the profiled sheet overlaps each row. The profile of the upper row should overlap the lower sheet more when the angle of inclination is smaller.

Pediment overhang

The building’s pediments and cornice area are two more places where the roofing shouldn’t protrude beyond the lines of the structure. Refer to this overhang as the front line. The most common methods for implementing a pedimental overhang device are either installing a wind board or installing a special wind bar. In this instance, there are differences in the profiled sheet consumption on the roof between the two scenarios.

We can infer from all of the above that the following factors must be considered when determining the norm of consumption of a profiled sheet on the roof:

The magnitude of the vertical overlap;
The size of horizontal overlap;
The size of the pedimental overhang;
The size of the cornice overhang.

The simplest method for doing this is to sketch out a layout of the corrugated board sheets, accounting for every detail of a specific roof.

We can determine the norm of a profiled sheet for a 1 m2 roof by dividing the coverage area, as determined by the scheme, by the area of a single corrugated board sheet. The area of the sheet can be identified by the corrugated board seller, and it will vary based on the corrugation brand, height, and wave of profiled sheet.

In this instance, it is important to note that profiles typically include the value of the entire usable area of the sheet in their technical characteristics. Because the useful area accounts for the size of the overlap between adjacent corrugated board sheets in a row, it is always marginally smaller.

The same principle applies if corrugated board is to be used for the facing facade or fence arrangement. This determines M2 consumption. The only distinction is that only the overlap between the corrugated board sheets needs to be considered when determining the profile consumption for vertical surfaces. In addition, there may be a two-fold reduction in the overlap between profile rows when installing corrugated board vertically.

The best course of action is to order special corrugated board fasteners right away when placing an order for roofing, facade, or fence materials. These fasteners require about 6–8 pieces per square meter of surface area.
