Classifications:

Color Coated Steel PPGI/PPGL sheet is usually classified in a variety of ways according to the site of application, the wave height of the plate, overlapping structure, and raw material. Common classification of the following categories:
1. According to the site of application categories - roof panels, wall panels, floor boards and ceiling panels. Use color steel plate at the same time doing decorative wall panels, architectural decorative effect is novel, unique.
2. according to the wave of high classification -  high-wave plate (wave height ≥ 70mm), medium-wave plate (70mm>wave height≥30mm)with low-wave plate (wave height <30mm)
3. According to the raw material- hot galvanized substrate, thermal galvalume substrate material - and hot dip galvanized aluminum panels.
4. slab constructed categories - divided into lap, to undercut and withhold structure. Undercut withheld in the high wave plate is appropriate for higher water requirements roof panels; lap in the high wave plate galvanized sheet cover with a floor; lap low wave plate is appropriate for the wall panels.
