Package
Plastic Bag
Wooden case
In CIVMATS, all of our stainless steel square pipes & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes & tubes together in batches. However, for some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation. For enhanced customer experience, we also provide dedicated package as per your special requirements.
Logistics
By Sea
By Air
By default, we will quote based on sea transportation, such as FOB, CFR, CIF and the like for most enquiries or orders. Quotation based on air transportation is also optional upon your request for urgent demands.
