At present, about 75% of the color steel coils in the world are used in construction, and more than 90% in China. In the construction market, from the original louver to the present outdoor decorative curtain wall. With the development of steel plate
and coating technology, color steel coil is more and more widely used in architecture. However, color steel coil is mainly thin plate, which is mainly used in the field of building envelope, so it is generally not a structural part, but the use of
large-span arch plate with high strength and thick specification also plays a role in the structural part.
Color coating new green building materials
Compared with traditional building materials such as traditional concrete, color steel coil meets the requirements of green building materials. It is a kind of environmental protection material with beautiful
shape, novel shape, rich color, strong decoration, flexible combination and diverse architectural style.
High strength (yield strength up to 550MPa), good skin rigidity and waterproof performance.
Seismic performance: as the color steel coil
is continuously laid in the long direction on the roof, the fastener is connected. The material has the advantages of high strength, good toughness and good ductility of steel, which can be used for different directions of seismic forces. Compared with
other building materials, it has obvious advantages of brittleness and non deformation. In addition, due to the light weight of the roof, the center of gravity of the whole building moves down, which is conducive to reducing the earthquake damage.
Factory prefabrication can make the accuracy within 2 mm, 3-4 times higher than the traditional cast-in-place concrete construction accuracy, and reduce construction waste.
