Metal roofing sheets are building envelope materials made from galvanized, zinc-aluminum-coated, or aluminum alloy sheets that are extruded and surface-coated. They offer advantages such as light weight, high strength, earthquake resistance, moisture resistance, fire resistance, and a variety of colors. They can be used for both roofs & walls. Wanzhi Steel offers metal roofing panels in all materials, including galvanized sheet, galvalume steel sheet, aluminum sheet. These sheets are available in various forms, including corrugated sheet, stone-coated roof tiles, box-shaped sheet, and flat sheet. We also offer color coating services. If you are interested, welcome to contact us.

Offers excellent overall performance. The coating contains aluminum, zinc, and silicon, with a lifespan 2-6 times that of galvanized steel. Alu-zinc roofing sheet also offers superior corrosion resistance.
Provides basic rust protection, is economical and practical, versatile, and cost-effective, making Galvanized roofing sheet suitable for indoor use or mildly corrosive environments.
4×8 Galvanized Roofing Sheet
Aluzinc Roofing Sheet
The coating contains aluminum, zinc, and magnesium. ZAM sheet offers exceptional corrosion resistance and self-healing capabilities.
Extremely corrosion-resistant, lightweight, and relatively low in strength. Suitable for coastal environments.
Elegant and distinguished, with an extremely long lifespan, but also the highest cost. Oxidation can lead to a patina on the surface.
Self-healing, with a lifespan of 60-100 years. Easy to machine and weld, but high in cost. Unsuitable for environments with persistent humidity.
Extremely strong and corrosion-resistant, but also expensive. 304 or 316 grade stainless steel roof panels are typical.
This most traditional and common corrugated sheet features a simple structure and low production costs. It offers excellent strength and is used for large-scale roofing applications such as industrial and warehouse roofs.
This sheet creates a seamless, continuous roof surface through locked seams, resulting in a simple, streamlined appearance. With no exposed screws, it offers excellent leak-proofing and wind resistance.
This sheet features interlocking square units, creating a strong geometric surface. This sheet offers a highly decorative aesthetic and is used for antique restorations and high-end decorative roofing and wall cladding.
This sheet is rolled into a three-dimensional profile that mimics traditional terracotta tiles or stone slabs, preserving a classic aesthetic. It offers the lightweight durability of metal and is an excellent alternative to heavy natural materials.
Common shapes of corrugated steel sheets
The high-ribbed trapezoidal profile provides exceptional load-bearing capacity and structural strength. Used for roofing and wall systems in heavy-duty industrial plants and large venues.
This tile is coated with natural colored stone particles, emulating the texture and color of traditional tiles. It combines the lightweight, fire-resistant durability of metal with the UV resistance of stone, and is suitable for high-end residential applications.

The material’s low density (for example, aluminum is only one-third that of steel) effectively reduces structural loads. Furthermore, alloying and machining processes achieve higher strength.
For example, roof panels based on galvanized steel or aluminum sheets, with a surface alloy coating, resin, or stone protective layer, provide exceptional resistance to corrosion, acid and alkali, aging, and high and low-temperature environments, resulting in a service life of up to 70 years.
The surface reflects solar heat, and a special coating reduces heat absorption, lowering air conditioning energy consumption. The metal’s non-combustibility ensures Class A fire protection.
The lightweight material supports riveting and welding, enabling flexible installation and significantly reducing construction times.
Excellent plasticity allows for the perfect creation of complex curved surfaces. The surface can be anodized, painted, and treated in a variety of finishes, offering hundreds of colors.
Please take a look at our workshop production line and the production process of color-coated metal roof panels.
For example, in automobile manufacturing plants, machining centers, and logistics warehouses, the core requirements are economy, load-bearing capacity, and large spans. Trapezoidal and corrugated sheet metal are preferred. Galvanized steel and ZAM sheet metal are preferred.
Such as the Beijing Bird’s Nest, convention centers and theaters, shopping malls, and high-speed rail stations, standing seam panels, aluminum-magnesium-manganese alloys, and galvanized steel are recommended.
High-end villas and residences, resorts, and guesthouses, corrugated sheet metal, wood-grain transfer sheet metal, and sand-gravel-coated metal tiles are commonly used.
Greenhouses and farms, cold storage facilities, and food factories, corrugated sheet metal and sandwich panels are recommended. Galvanized steel and galvanized steel are recommended.
Metal Roofing
Before installing the metal roof sheet, thermal expansion should be taken into account. During installation, gaps should be reserved and anti-expansion accessories should be used.
Metal roof sheets are noisier than other types of roofs, especially in rain, snow, and lightning weather. During installation, sound insulation materials can be used to reduce external noise.
Regular maintenance of metal roof sheets includes cleaning the surface of the roof sheet, checking for damage, and whether the coating is damaged.Regular maintenance can promptly deal with potential problems and extend the life of the metal roof sheet.
