Which material is more durable for hard fast doors

Rigid high-speed doors are a common industrial door and are widely used in factories, warehouses, parking lots and other places. With the development of technology and advancement of materials, there are more and more types of materials for hard fast doors. So, which material is more durable?

Below I will start from several common materials and conduct analysis and comparison.
Steel Steel is one of the main materials of hard rapid doors. It has excellent strength and durability and can withstand the test of harsh environments. After special treatment, steel has anti-corrosion and anti-rust properties and can be used for a long time in harsh environments such as moisture, high temperature, and low temperature. At the same time, the steel surface is smooth and easy to clean, which can maintain the beauty of the door body. However, due to the heavy weight of steel, installation and operation are relatively complex and the price is high.

Polycarbonate (PC) material Polycarbonate is an engineering plastic with good wear resistance, impact resistance and weather resistance. It is characterized by high transparency, high temperature resistance, good flexibility, and high UV resistance. The hard fast door made of polycarbonate allows you to see the situation outside the door through the door body, which improves safety and convenience. Because the polycarbonate material itself is lightweight, installation and operation are easier, and the cost is lower. However, the hardness of polycarbonate material is relatively low and not strong enough, so it is easily scratched or broken by impact.

Aluminum alloy Aluminum alloy materials have the advantages of light weight, corrosion resistance, wear resistance, and high strength, and are widely used in the manufacture of hard rapid doors. Hard fast doors made of aluminum alloy can adapt to various environments, including moisture, high temperature, low temperature, etc., are not easily oxidized, and have a long service life. At the same time, aluminum alloy materials are light in weight, easy to install and operate, and the price is relatively low. However, aluminum alloy materials are not as strong as steel and are easily deformed or damaged by impact.
In summary, steel, polycarbonate and aluminum alloy are widely used in hard fast doors. From the perspective of durability, steel and aluminum alloys are relatively more durable, able to withstand harsh environments and have a longer service life. Polycarbonate materials, on the other hand, have relatively low hardness and wear resistance and are prone to scratches or chipping. However, the choice of hard fast doors in different situations requires comprehensive consideration of many factors, such as use environment, safety, installation convenience and economy, etc.
