·They are lightweight
It weighs 6–14 kilograms per square meter, equivalent to one-thirtieth of a brick wall. Compared to traditional building materials, corrugated steel roofing panels are lighter, which helps reduce the load on the building structure and lower construction costs. Additionally, due to their lightweight nature, corrugated steel roofing panels are also easier to install and transport.
·They have high strength and durability
The metal roofing sheet is made of high-strength steel, offering excellent resistance to pressure, wind, and snow loads. This material can withstand extreme weather conditions such as strong winds, rainstorms, and heavy snowfall, thereby protecting the building from damage.
·They have excellent corrosion resistance
The iron sheets roofing is treated with galvanizing or other protective chemical coatings to prevent algae growth. At the same time, they have excellent corrosion resistance and are not easily corroded during long-term use. It can still be restored to its original state after cleaning. If the service life exceeds 30 years, it can shorten the construction period by more than 40%.
