Compared with traditional concrete and other traditional building materials, color coated steel plates, color steel plates, color coated rolls, and color steel coils meet the requirements of green building materials. The appearance is novel and novel, the color is rich, the decoration is strong, the combination is flexible and can express different architectural styles, and it belongs to environmentally friendly materials.
High strength (yield strength up to 550MPa), good skin stiffness and good water resistance.
Excellent seismic performance: Because the color coated plate, color steel plate, color coated roll, and color steel coil are continuously laid in the long direction on the roof, the fasteners are connected. The material has high strength, good toughness, and the steel can be extended. It can be applied to the seismic force in different directions, and has obvious advantages compared with the brittleness and non-deformability of other building materials. In addition, due to the light weight of the roof, the center of gravity of the galvanized whole building moves down, which is beneficial to reduce the earthquake damage.
Factory prefabrication can make the precision to within 2 mm, which is 3-4 times higher than the traditional concrete cast-in-place construction accuracy, and reduce construction waste. Convenient construction and installation, reducing the workload of installation and transportation, shortening the construction period, and reducing carbon emissions.
Saving land, water and other resources: Light steel envelope structure (color coated steel plate) has a weight of 6-12 kg/m2, steel-concrete structure is 250-300 kg/m2, and brick wall is 400 kg/m2. . Therefore, the use of color coating on the selection of materials can save a lot of cement, bricks, tiles, etc., thereby greatly reducing the use of cultivated land and greatly reducing the occupation of water resources. Due to the greatly reduced self-weight of the roof and wall, the underground basement of the building can also be reduced accordingly, and the load-bearing structure can also be made of light steel structure (especially the single-story car-free plant is more obvious).
Recyclable use: The biggest advantage of steel materials is that they can be re-smelted for re-smelting, achieving recyclability and sustainable development, while bricks, tiles or concrete can only add construction waste. According to the study of CORUS, ordinary color-coated plates are used as smelting scraps, which can be used in general converters. However, if they are painted with PVC sol, DIOXIN will be produced, which is more suitable for electric furnace scrap.
The development trend of color steel plates is also to “3R manufacturing” [reduce, reduce and recycle], or three alternatives to green steel (replace old steel with new steel, use steel Materials are replacing other materials and replacing old uses with new ones.
