As one of the more professional China color corrugated steel sheet manufacturers, we will introduce one of the most familiar color corrugated steel sheets.
Copper, lead, graphite and unprotected steel plates shall not be used in direct contact with the color coated plates. The loss of copper plates shall be avoided on the steel plates. Painted panels shall not be used in direct contact with wet or weathered wood and wet cement.
The reasons are as follows: the moisture contained in the wood, the corrosive chemicals in the weathering treatment will shorten the life of the color corrugated steel sheet plate, the chemically treated wood loss causes corrosion, and the wet cement alkalinity can react with the steel plate coating.
