How To Pack QN Stainless Steel Sheet & Coil
In GHT, all of our stainless steel coils are packaged as per international standard to prevent any possible damage or loss. By default, for quantity less than 1 whole compete coil (our MOQ is 5 tons), we will use woven plastic bag to cover SS coils and then fix them upon wooden pallet for further protection. We can also package the SS coils as per your special requirement, though this can incur extra cost.
In GHT, all of our stainless steel sheets are packaged as per international standard to prevent any possible damage or loss.
