Types of metal tiles for the roof

Because of their many options, durability, and aesthetic appeal, metal tiles are a popular choice for roofing. These tiles are made from a variety of metals, including copper, aluminum, and steel, each of which has special qualities that fit well with different types of architecture and climates.

One of the most popular and reasonably priced materials are steel tiles. Because they are sturdy, they are perfect for locations that frequently experience extreme weather. Protective coatings are frequently applied to steel tiles to increase their longevity and rust and corrosion resistance.

Because aluminum is strong and lightweight, it is a good material for coastal areas where other metals can corrode due to the salt air. They provide a sleek, contemporary appearance that goes well with modern architectural designs, and they are resistant to rust.

Roofs can have a timeless elegance thanks to the unique appearance of copper tiles, which naturally develop a patina over time. Long-term sustainability is ensured by copper’s high durability and low maintenance needs, despite its higher initial cost.

Corrugated Metal Tiles Traditional style with ridges for water drainage.
Standing Seam Metal Tiles Modern, sleek panels with concealed fasteners.

Classification of metal tiles

The metal tile is composed of galvanized sheet steel, which has been coated with unique stable dyes to improve the design and provide extra protection against corrosion processes. The surface mimics conventional roofing coatings with a distinct geometric profile. The collection of technological steps is intended to improve the roofing’s functionality. The primary factor that separates high-quality materials from low-quality is thought to be the warranty duration. The paint color and the profile’s geometry serve solely as design elements; they have no bearing on the effect’s functional properties.

There are two sorts of warranties: one for each type of anti-corrosion protection.

  1. Polymeric dye warranty. Indicates the minimum period that should withstand paints. During this time, they should not crack and exfoliate, change their original appearance, etc. D. These indicators mainly depend on the degree of protection of the paint on hard ultraviolet radiation and plasticity parameters. The fact is that large temperatures from plus to minus become the cause of significant fluctuations in the linear sizes of the metal tile, and the metal in the values ​​of thermal expansion takes the first place among all solid bodies. To compensate for the extensions, the paint should have plasticity, the higher it has this parameter, the more time microcracks do not appear on the surface. Microsiness in the future increases to critical sizes, water will fall on a zinc coating, detachment begins. Not only the appearance spoils, but also the corrosion processes accelerate.
  2. Warranty of anti -corrosion coatings. As already mentioned, dyes serve only with additional protection, as the main one, zinc coating is used. The better and thicker it is, the more guaranteed service life. The most modern and expensive types of metal tiles have zinc alloys with aluminum, which significantly improves technical parameters. The anti -corrosion coating should prevent the appearance of through corrosion and, accordingly, leaks requiring roofing repair.

Classification by zinc coating

Currently, the entire metal tile is classified into three classes based on the quality of the anti-corrosion coating, which is a very important indicator.

Class of zinc coating Technical description
III class zinc The weight of zinc coating in the range of 80–140 g/m2. The weakest anti -corrosion protection. Real life of 5-10 years. Such metal tiles are not recommended for residential buildings, repair of leaks and a complete replacement of the roof will cost too much.
II class zinc The weight of zinc coating in the range of 140–180 g/m2. The service life, subject to the recommendations of the manufacturer, can be 25 years. The most used coating class, in their operational indicators, is satisfied by most users.
The 1st class of zinc The weight of zinc coating in the range of 180–275 g/m2. The highest quality metal tile is recommended to be used on sea coasts, in cities with a lot of smog. Smilo contains aggressive chemical compounds, and sea air is oversaturated with salt. To improve the technical characteristics of zinc, up to 5% aluminum is added to it. The life of such roofs is up to 50 years.

Premium steel is used to make metal tiles; this steel forms the foundation of the profile sheet.

Hot galvanizing involves impregnating steel with a red, heated zinc solution.

Unfortunately, poor -quality products are sold on the shelves of many stores, especially for manufacturers from China. A layer of zinc on such sheets can be less than 40 g/m2, which is much lower than the established norms. But there is no need to blame the Chinese, domestic trading companies are to blame. They do not want to buy high -quality metal tiles from China, and they have it, according to the indicators of technical development, this country has much overtook the Russian Federation. It is only worth listing the well -known brands of electronics, mechanical engineering, industrial automation. Domestic businessmen buy products from underground unlicensed manufacturers to increase their profits – this explains the big problems with the quality.

Certain manufacturers apply electrolysis galvanizing to the metal, resulting in a very thin zinc layer and, consequently, low indicators of protective coating.

This article explores the different kinds of metal roof tiles with the goal of giving homeowners a comprehensive knowledge of their choices. Every type, from contemporary options like standing seam panels to more conventional designs like corrugated metal, has advantages over the others in terms of maintenance, durability, and aesthetics. We enable readers to make well-informed decisions about roofing solutions that meet their practical requirements and aesthetic preferences by providing an accessible explanation of these options."

Classification by dyes

External surfaces of metal tiles are covered with simple or complex colored polymer coatings. Paints protect the zinc layer from oxidation and play a decisive role in the design characteristics. The fact is that zinc is also oxidized, though these processes pass slowly. The later the metal begins to contact with oxygen and active chemical compounds, the greater the period of guarantee of the coating. This parameter depends on the two factors: the type of polymer dye and the technology of its application. They should be resistant to mechanical damage, have plasticity, maintain its original color, do not crack. What paints are used to paint the surfaces of the metal tile? There are three types of polymer coatings.

Polyester

Most often, external surfaces are covered with a matte or glossy polyester – a variety of polyester colors. Such a coating has cheap types of metal tiles. Polyester is made on the basis of polyester resins, various inorganic fillers and pigments are added to improve abrasion and color changes and color changes. Paints have good indicators of the resistance of UV rays, are not afraid of heating to +120 ° C, resistant to atmospheric precipitation, in the degree of adhesion to the metal parameters satisfactory. Disadvantage – negatively react to alkalis, have low dielectric characteristics. The appearance of static electrical stresses significantly accelerates the process of oxidation of metals at the site of the connection of steel and zinc. As a result – the tightness of the coating is disturbed, the zinc film is exfoliated and damaged, the water gets access to the metal.

Polyurethane

Is even used for painting the bodies of passenger cars, and it has increased indicators of mechanical damage. Two components in a solvent that is natural. does not become discolored, does not react with chemicals, and does not become afraid of intense UV light. satisfies the criteria set forth by European Standard ISO 12944. Belongs to the intermediate segment in the price class.

The two-component composition includes an aliphatic isocyanate-based hardener. Because of its high plasticity when subjected to mechanical damage, it exhibits enhanced indicators of resistance to unfavorable weather conditions and does not crack. At the moment, producers are continuously creating novel additives that enhance operational qualities.

Plastic

The most costly metal tile finish coating, with a layer as thick as 200 μm. The paint, which is based on polyvinyl chloride, has improved wear resistance and durability characteristics. The ability of the plastisol to independently tighten microcracks extends the life of the metal tile considerably. It is possible to create a structured surface with large thickness.

The roofing material’s surface can be textured, matte, or glossy. Because of these options, purchasers can select the one that best fits their structure. The choice of color for the operational characteristics has no bearing on the reverse side, which can be gray or the color of the front coating.

PVDF coating

30% acrylic and 70% polyvinylenfluoride make up the composition. possesses a very high degree of mechanical damage resistance and does not fear repeated freezing cycles or measurements. Does not react when in direct contact with alkalis and solutions containing acid; it can be used in smog-filled urban environments. It contains novel additives that provide UV protection, are immune to the damaging effects of sea salt, and can withstand temperatures as high as +120 °C. only when used on a specific primer.

Puralum is comparable to a metal tile coated in PVDF in terms of stability and service life. It is composed of a blend of acrylic and PVF.

Types of metal tiles, depending on the size and thickness of the metal

One can achieve galvanized steel through chemical or hot galvanization. Depending on the technology’s features, the surface could have normal or nonexistent sparkles. The ultral coating is found in the best quality. This kind of galvanizing creates a consistent layer of metal over the whole surface.

The galvanized steel leaf

The finest metal tile is composed of unique KS D 3770 brand galvanized steel, and its surface is coated in an aluminum-zinc alloy. Even though the protective film weighs only 50 g/m2, its extended guaranteed operation period sets it apart. Compared to a regular zinc coating of the same thickness, corrosion resistance is orders of magnitude higher.

The standard sheet width is 118 cm, while the length ranges widely, from 1.5 m to 6.5 m. When choosing a material for circumcision, the number of joints and unnecessary waste should be kept to a minimum.

Steel sheet, 0.4–0.6 mm thick. The thinnest is typically used with a short service life when building roofs for essential structures and buildings. Prestigious buildings use 0.5 mm thick metal tiles.

Specifications of metal sheets

Metal tiles can also be made from aluminum and copper in addition to steel. The latter are exceedingly rare and costly.

Sheet profiles

As previously stated, the profile is selected based on the building’s style; it has minimal bearing on the coating’s physical properties.

Types of metal tiles depending on the dyes of the front surface

When different colors and coating technologies are used, the roof’s exterior surface changes. The following categories of exterior coatings are the most well-liked by developers.

Brilliant and matte polyester

The metal tile’s front side is commonly identified by the international designation re. Such dye is used to stain all known profiles; the cost is indicative of the least expensive option. It is not advised to use this subpar quality material on important buildings. There is no more than 25 microns of coating thickness. MRA indicates matte; the addition of Teflon to the paint composition modifies the paint type. The coating layer has a 15-year service life and thickens to 35 microns.

Pural

Paint made of polyurethane, which has novel ingredients to boost UV protection. does not lose any of its initial physical characteristics between -60 °C and +100 °C. Rejects atmospheric precipitation flawlessly. Paint with a minimum 50 micron thickness and a maximum 30-year lifespan. more expensive than polyester coatings. Teflon is added to the matte finish, which can be glossy.

High strength, resistance to loads, and resistance to mechanical damage are characteristics of pure metal.
