4)All the parts that need sealants should wipe the attachment surface clean,to make sure there is good adhesion on color steel.The glue joint should be full and dense to avoid water leakage.


5)The PVC films on panels,please peel it off within 3 ~ 4 months,after shipment.Otherwise it will have chemical reaction and make it very difficult to peel off.

7)During the on-site cutting process of wall panel, the bottom surface of the cutting machine should not be in direct contact with the color steel surface.It’s best padded with thin plywood on the panel,then cut.The burrs on the cutting end need to be removed and installed in time.


8)Iron scraps are generated after cutting and drilling holes,and these iron filings on panel surface need to be cleaned.These iron scraps must be cleaned up in time and must not be left overnight.Iron filings can rust in a humid environment. The rust spots are verified to be removed after the surface of the board is formed, and the paint surface or even the substrate may be damaged for a long time.Similarly, other cut-off color steel heads, iron bars pulled by aluminum alloy steel nails, etc. should be cleaned up in time.
