Classification:

Corrugated boards are usually classified in various ways according to the application site, board wave height, lap structure, and material.

Common classification methods are as follows:

(1) According to the classification of application parts, it is divided into roof panels, wall panels, floor decks and ceiling panels. In use, the color steel plate is used as the wall decoration board at the same time, and the architectural decoration effect is relatively novel and unique.

(2) According to the wave height classification, it is divided into high wave plate (wave height ≥70mm), medium wave plate and low wave plate (wave height <30mm)

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

(4) According to the structure of the board seam, it is divided into lap joint, undercut and withhold structure, etc. Among them, the undercut and crimped medium and high wave boards should be used as roof panels with high waterproof requirements: the lapped medium and high wave galvanized sheets are used as floor coverings; the lapped low wave boards are used as wall panels.
