Roofing sheet classification

Profiled steel plates are usually classified in a variety of ways according to the application part, the wave height of the plate shape, the overlap structure, and the material. Common classification methods are as follows:

(1) Classified by application part-divided into roof panels, wall panels, floor decks and ceiling panels, etc. In use, color steel plates are used as wall decoration panels at the same time, and the architectural decoration effect is relatively novel and unique.

(2) According to wave height classification-divided into high wave board (wave height ≥ 70mm), medium wave board (wave height <70mm) and low wave board (wave height <30mm)

(3) Classified by substrate material-divided into hot-dip galvanized substrates, hot-dip galvanized aluminum substrates, and hot-dip galvanized aluminum substrates.

(4) Classified according to the structure of the plate seam-divided into overlapping, undercut and crimping structures. Among them, the undercut and crimped medium and high-wave boards should be used as roof panels with higher waterproof requirements; the overlapped medium and high-wave galvanized sheets should be used as floor panels; the overlapped low-wave boards should be used as wall panels.

Application

Roofing sheet is also called profiled board. It uses color coated steel sheet, galvanized sheet and other metal sheets to be rolled into a variety of wave-shaped profiled boards. It is suitable for industrial and civil buildings, warehouses, special buildings, and large spans. Steel structure house roof, wall and interior and exterior wall decoration, etc. It has the characteristics of light weight, high strength, rich color, convenient and fast construction, earthquake resistance, fire resistance, rain resistance, long life, and maintenance-free. It has been widely promoted and applied.

Advantage

Steel structure house panels, mobile house panels, etc.

(1) The appearance is beautiful and novel, the color is rich, the decoration is strong, the combination is flexible and changeable, and it can express different.

(2) Light weight (6~10kg/m&sup2;), high strength (yield strength 250~550MPa), good skin stiffness, and good waterproofing performance;

(3) High quality factory products

(4) Convenient construction and installation, reducing the workload of installation and transportation, and shortening the construction period;

(5) The profiled steel plate is an environmentally friendly building material and can be recycled. The promotion and application of profiled steel plate conforms to the policy of sustainable development of the national economy;
