Surface treatment (Protection)

Chemical Passivation  Oiled(optional)  Untreated  Resin Coated

Remark:

1. imperfections such as small pits, variations in spangle size, dark spots, stripe marks , light passivation

stains ,stretch leveling breaks,skin pass marks,scratches, zinc run off marks are permissible on surface.

2.  chemical passivation protects the surface against humidity and reduces the risk of formation of “white rust” during transportation and storage, local discolouring as a result of this treatment is permissible and does not impair the quality.

3.  Oiling also reduces the risk of corrosion of the surface.

4. Resin Coated offers additional corrosion protection by transparent organic film. Specially protection against anti-fingerprint

Storage Transportation and Loading /unloading

Storage

1) keep the product dry.

2) Store the product in a dry and well ventilated area preferably indoors. to avoid condensation and moisture penetration. Store the productions in a roofed storage area.

3) Don’t put the products where they could be exposed to sand and dust. If sand or dust build up on a sheet.they can damage zinc or paint coatings, sand and dust also hinder drying and thus promote white rust formation.

4) Don’s stack sheets or coils excessively high. This is important for safety as well as for the prevention of sheet deformation or other damage. Inventory terms should be as short as possible(Within 6 month)

Transport and Loading/unloading:

1) Don’t push the cut sheets or roll the coil with a forklift. Since this could cause scratching.

2) When transporting coil in a truck, care should be taken to protect the coil surfaces against damage. Using preferably. A rubber sheet beneath the coil or an exclusive transport stand.

3) When transporting coils. Firmly fix the stacked sheets so that they do not slip off due to vibration.
