Zinc Roofing Sheets

Zinc roofing sheets, also known as zinc roofing materials, are a widely used building material, favored for their excellent corrosion resistance, durability, and relatively lightweight. With corrugated and other shapes, other elements can also be added during production to form zinc alloy roofing sheets. Wanzhi Steel is a manufacturer specializing in the production of zinc roofing sheets, aluminum roofing sheets, GL sheet, and galvanized roofing sheets. The thickness, length and width of the board can be customized. Welcome to contact us for more information.

zinc roof sheet weight formula

Flat sheet

Weight(kg/m²)=Substrate thickness(mm)×7.85+Galvanized layer weight(g/m²)×0.001+Coating weight(g/m²)×0.001.

Corrugated board

Weight(kg/m²) = weight of flat board (kg/m²) × expansion coefficient.

Expansion coefficient of common corrugated sheet

• Wavelets (corrugated): wave height 15-25 mm, spreading factor 1.05-1.08.
• Medium wave (trapezoidal wave): wave height 30-50mm, expansion factor 1.10-1.12.
• High wave (industrial): wave height 50-100mm, spreading factor 1.12-1.15.

Key features of Zinc roofing sheets 

• Corrosion resistance: Zinc has good corrosion resistance and can maintain its integrity even in adverse weather conditions.
• Durability: Zinc roofing materials have a long service life and can withstand the erosion of various natural environments.
• Lightness: Compared with other roofing materials, zinc roofing materials are lighter and easier to transport and install.
• Recyclability: Zinc is a recyclable metal that meets environmental requirements.
• Aesthetics: Zinc roofing materials have a unique appearance and texture, which can enhance the overall aesthetics of the building.
• Flexibility: Zinc roofing materials can be customized according to building needs, such as shape, color, size, etc.
• Easy to install: The installation process of zinc roofing materials is relatively simple and can be completed quickly, reducing construction costs.
• Low maintenance cost: Due to its excellent corrosion resistance and durability, the maintenance cost of zinc roofing materials is relatively low.

Zinc Roofing Sheets Applications

• Residential roofing: sloped roofs, canopies, balcony roofs, rural scaffolding to replace traditional fragile and flammable tiles.
• Sunroom/glass roof: as a waterproof layer or auxiliary cover.
• Commercial buildings: shopping malls/supermarkets, hotels/office buildings, schools/hospitals building projects, fast construction, long-term maintenance-free.
• Factories & Workshops: light weight, reduce building load, use in warehouse/logistics center can prevent rain and rust.
• Agriculture & Forestry: greenhouse greenhouses, farms, granaries/feed stores, easy to clean, corrosion resistant, moisture and rodent proof.
• Transportation facilities: parking lot/charging shed, highway fencing, sun and rain protection, economical and practical.
• Sports & Leisure: stadium/swimming pool bracket roof, rust-resistant and beautiful, reduce the support structure.
• Temporary construction: construction site simple house, resettlement house in disaster area, exhibition hall/activity shed, anti-seismic and windproof, flexible disassembly, short-term use.

Plain zinc sheet

Because Zinc roofing sheets have more than one shape. At the beginning of processing, it is a flat zinc sheet, which can be used directly as a roof sheet, but the zinc sheet after the tile pressing will provide better impact resistance, which is the corrugated zinc sheet. After being cut to size, it forms a zinc roof sheet, which is mostly in the shape of broken waves. The only difference from the flat zinc sheet is the shape.

How long will a zinc roof last?

Zinc can last 80-100 years when used in roofing and even longer when used as a wall system. No other material has such a long lifespan other than copper roofing.

Do Zinc roofing sheets rust?

Zinc is a metal that is not easily rusted and is very corrosion-resistant. Therefore, zinc is often used as a coating to protect steel or other metals, such as galvanized sheets, galvanized strips, and galvanized color-coated sheets, all of which use zinc as a coating to extend their service life.

Is zinc better than aluminum for roofing?

Most metal roofs are built to last. Zinc has a lifespan of up to 100 years (some roofs last longer), and aluminum comes in third with an average lifespan of 50 years. This makes zinc a better choice for roofing than aluminum. But more expensive than aluminum.

Aluminum zinc roofing sheets

Sometimes abbreviated as zinc-aluminum roofing sheet, zinc-aluminum roofing sheet is mainly made of a steel plate as the base material, with a layer of zinc-aluminum alloy coated on the surface. The zinc-aluminum alloy coating is usually applied through a hot-dip coating process to ensure good bonding between the coating and the base material. It has better performance than pure zinc coating. It can be used not only as a roofing material but also for walls, sound insulation boards, decorative boards, etc.

Zinc-coated roofing sheet

Galvanized sheet is currently the use of a relatively high rate of a building material, is a layer of zinc plated on the surface of the steel, the price is cheaper than aluminum zinc plating, with good corrosion resistance, weather resistance, durability, long service life. zinc roof sheet is mostly referred to zinc-coated roofing sheet.
