5,Color steel sheets transport handling & storage:

1. Before unloading all the wall cladding materials,they must be checked.Please refer to related orders and delivery notes to make sure all the materials are in correct quantities and lengths.If any discrepancies,please record immediately on the proof and notice us by e-mail or calling;
2. We suggest using forklift or telescopic forklift to unload steel sheets. When using fork or driving on uneven ground,please be careful not to wrap or damage the floor.One time only advise to unload one package;
3. When discharging manually, make sure that proper operators wear enough protective clothing, gloves and shoes at hand. Please note that unloading is the responsibility of the customer;
4. If possible, wall claddings are better to be offloaded to the area where they will be used to.In this way,it could reduce the risk of on-site damage;
5. If metal sheets couldn't be used in short time,please don't make the packages in good status,and stack in clean and dry place to avoid water.

1. Cleaning of color steel sheets: Generally, most of the dust and residue on the surface of the steel plate can be removed with clean water. In theory, it needs to be cleaned at least every six months. In areas with more salt spray and heavy industrial dust, cleaning should be more frequent. For stubborn stains that cannot be washed out, use a weak detergent or a household ammonia solution as follows;
2. Refinishing of color steel wall sheets: If scratches occur during installation and use, it may be necessary to repaint the defective part. Improper or excessively applied paint can damage the entire surface. It is best not to fix the scratches that appear inconspicuous at 6 feet because normal wind erosion can cover them. To repair the paint, it is only necessary to repair the peeled off part of the paint. Before the touch up, use alcohol to remove dirt, paraffin and other contamination.
