Welcome!
Metal roof tiles are roof tiles with waterproof, anti-corrosion and durability characteristics based on metal sheets through different production processes and surface treatments. It usually has the advantages of light weight, high strength, corrosion resistance, fire prevention, dustproof and self-cleaning, etc., and is easy to install and low maintenance cost. Metal roof tiles have a long service life, ranging from 30 to 50 years or even longer. Metal sheets have excellent waterproof performance, which can effectively prevent rainwater leakage.
With its excellent performance, wide range of application scenarios and long service life, metal roof tiles have become one of the indispensable roofing materials in modern buildings. With the continuous progress of science and technology and the improvement of people's requirements on building quality, the application prospect of metal roof tiles will be even broader.
Asphalt shingle, also known as linoleum shingle or fiberglass tire asphalt shingle, is a new type of polymer waterproof material. It is mainly made of asphalt-based binder material (i.e. asphalt) and fiber or fiberglass carcass, then covered with colored mineral granules or colored sand made of sheet tile. Asphalt shingles have been widely used in Europe and the United States, and gradually emerged in the domestic market, especially in villas, houses, sloped roofs and flat to slopes and other projects have been widely used.
Asphalt shingles are relatively light and easy to construct, and at the same time have good weather resistance to withstand harsh climatic conditions. By covering the surface with colored mineral granules or colored sand, asphalt shingles can present a variety of colors, making the building appearance more beautiful. Asphalt shingles have good fire resistance and can effectively stop the spread of fire. As a waterproof material, asphalt shingles have excellent waterproof performance, which can effectively protect buildings from rain erosion. The construction of asphalt shingles is relatively simple, and can be constructed using the dry method, reducing wet work and environmental pollution. Modern asphalt shingles are made of environmentally friendly materials, in line with the development trend of green building.
Asphalt shingles are low-priced, easy to construct, and fire-resistant and moisture-resistant. However, its life span is relatively short and it is poorly flame retardant, fragile and has a low safety factor. Asphalt shingles also have some limitations, such as a relatively short service life and may need to be replaced periodically; their performance may be affected under extreme high or low temperature conditions; and they have relatively poor fire retardancy and need to be strengthened with fire prevention measures.
