Specification:
Parameter:
Packing: 1.Bundle packing: 1) Each profiles surface protected by transparent or logo film, and several profile wrap to be bundle by shrink film. 2) Each profiles interleaf by EPE form, and several profile wrap to be bundle by shrink film. 3) Each profiles surface protect by film or interleaf by EPE form, and several profile roll by paper.  2.Wood pallets packing: Step 1: Dozens of bundle alu profile put on the wood pallet base, and fixed by strip film. Step 2: Cover the alu profiles by thick paper and wrap by shrink film. Step 3: Surrounded the pallet by numbers of wood strip and fixed to be firmed pallet by pvc or iron strip.  3.Carton packing: Each profile interleaf by EPE form or pack by plastic bag, dozens of alu profile put in carton and seal & strengthen by tape.
