Profiled steel plates for construction are divided into three categories: roofing plates, wall plates and floor plates. The model consists of three parts: profile code, usage code and plate characteristic code.

The pressing code is represented by the first letter "Y" in the Chinese pinyin of the word "pressing".

The usage codes are as follows:

The roof panel usage code is represented by the first letter "w" in the Chinese pinyin of the word "house";

The purpose code of the wall panel is represented by the first letter "Q" in the Chinese pinyin of the word "wall";

The purpose code of the floor slab is represented by the first letter "L" in the Chinese pinyin of the word "楼".

The plate type characteristic code is represented by the combination of the wave height dimension (mm) and the coverage width (mm) of the profiled steel plate.
