1 Packaging: Steel strapping for easy handling Wooden blocks or dunnage are put between the stacks to prevent organ shift while in shipping process. Surface treatment (optional): Black painting, rust preventive oil, plastic film. Galvanized piles can also be wrapped in a temporary protective plastic film to prevent scratching the surface. Customized packaging is available.
2 Delivery Information: Standard Lengths In Stock: 6m, 12m. Lengths: standard and custom. They Come with Sea Rail and Road Applicability Suitable for sea, rail or road transport, they are also strong enough on road application. The time of delivery is 15-30 days after receipt of payment, depending quantity and specification. Applicable to global export,with full document (Test Certificate, Packing List, Bill of Lading).
3 Handling precautions: Do not use slings or hooks without pads to come into direct contact with the pipe surface which may cause pipe deformation. Store in a cool,dry and well-ventilated place. To avoid rust before installation. Oversize and overweight cargo must comply with local shipping regulations.
