Packing Methods
General packing method:
- For honed tubes: anti-rust oil to be coated on the inside and outside surface of the honed tubes, plastic caps at both ends. Banding with steel or plastic strips, and then bale packing.
- For chrome plated rods: anti-rust oil to be coated on the surface of the rod and each rod to be packed in paper sleeve individually or plastic bubble wrapped and then packed in plywood boxes.
For single product which is more than 2 tons, iron crate will be used to strengthen the package.
Custom packing as per your requirement is acceptable.
