2) Over 5,000 tons of stock in stock, with a wide variety of sizes
3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging
1 Packaging: Steel banding for handling ease. Wooden blocks or dunnage is placed between the stacks to avoid organ shift during transportation. Surface treatment (optional): Black painting, rust preventive oil, plastic film. Hot-dip galvanized piles may be coated with a temporary protective film to avoid scratches in the surface. Customized packaging can be provided.
2 Delivery: Common stock lengths: 6m , 12m. Available in custom lengths. Come with Sea Rail and Road Applicable Suitable for sea, rail or road transport. The delivery time is usually 15-30 days upon receipt of payment, subject to quantity and specification. Suitable for worldwide export, with complete document (inspection certificate, packing list, bill of lading).
3 Precautions for handling: Do not use slings or hooks without pads to act directly upon the pipe surface to avoid the pipe being deformed. Keep in a cool, dry and well-ventilated place, avoid rust before install. Over sized and over weight shipment please comply with local shipping regulations.
