PP corrugated board is also called pressure type board. It is made of color coated steel sheet, galvanized sheet and other metal sheets. It is rolled and cold-formed into various wave type pressure plate. It is suitable for industrial and civil buildings, warehouses, special buildings, large The roof, wall and interior and exterior wall decoration of span steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, anti-seismic, fireproof, rainproof, long life and maintenance-free. It has been widely used.
Profiled steel sheets are usually classified according to the application site, plate height, lap joint structure, and material. The common classification methods are as follows:
(1) According to the application part classification - divided into roof panels, wall panels, floor panels and ceiling panels. In the use, the color steel plate is used as the wall decoration board, and the architectural decoration effect is relatively novel and unique.
(2) According to the wave height classification - divided into high wave plate (wave height ≥ 70mm), medium wave plate (wave height <70mm) and low wave plate (wave height <30mm)
(3) According to the material classification of the substrate - it is divided into hot-dip galvanized substrate, hot-dip aluminum zinc and hot-dip galvanized aluminum substrate.
(4) Classification according to the seam structure - divided into lap joint, undercut and buckle structure. The medium and high wave plates with undercut and buckled should be used as roof panels with high waterproof requirements; the galvanized plates for splicing of medium and high wave plates are used for floor coverings; the lapped low wave plates should be used as wall panels.
