Color-steel composite board is a composite maintenance board made of color-coated steel plates or other panels and bottom plates and thermal insulation core materials through adhesive (or foaming).

The compounding method usually includes explosive compounding, explosive rolling compounding, rolling compounding and so on. Composite materials can be divided into composite plates, composite tubes, composite rods and so on. Mainly used in anti-corrosion, pressure vessel manufacturing, power construction, petrochemical, pharmaceutical, light industry, automobile and other industries.

Composite materials can be divided into composite plates, composite tubes, composite rods, etc. according to their appearance.

Advantages: light weight, about 10kg~14kg/square meter, equivalent to 1/30 of a brick wall; good heat insulation, attracting and sealing performance; prefabricated building construction is convenient, flexible and fast installation, construction period can be shortened by more than 40%; Bright, beautiful appearance, no need for surface decoration; high strength, can be used as maintenance structure, load-bearing structure, bending and compression resistance, beams and columns are not required for general houses.
