Packaging and transportation of galvanized steel sheets

Packaging materials: Galvanized steel panels usually use wooden pallets or steel pallets as the basic packaging materials. Pallet selection depends on the weight and size of the product. In addition, boards, cardboard, foam, and other materials will be used to protect the steel plates.

Steel plate stacking: During the packaging process, steel plates need to be stacked correctly to ensure stability and avoid damage. Usually use a flat horizontal stacking method to avoid excessively high stacking to avoid pressure that may cause deformation or damage.

Protective measures: To protect the surface coating of galvanized steel panels, protective materials, such as plastic film or cardboard, can be placed on the surface of the steel panels to prevent scratches and friction.

Fixing and bundling: During the packaging process, binding straps or steel straps need to be used to fix the steel plates on the pallet to ensure stability and safety during transportation.
