Put the driers side the aluminum circle, keep the products dry and clean.
Use clean plastic paper, pack the aluminium circle, keep good sealing.
Use the snakeskin paper, pack the surface of the plastic paper, keep good sealing.
Next, there are two ways of packaging: One way is wooden pallet packaging, using the crusty paper packing the surface; Another way is wooden case packaging, using the wooden case packing the surface.
Finally, lay the steel belt on the wooden box’s surface, keeping the wooden box fastness and secure.

Aluminum circle of Henan Huawei Aluminum. meet the export standard. Plastic film and brown paper can be covered at customers’ needs. What’s more, a wooden case or wooden pallet is adopted to protect products from damage during delivery. There are two kinds of packaging, which are eye to wall or eye to the sky. Customers can choose either of them for their convenience. Generally speaking, there are 2 tons in one package, and loading 18-22 tons in 1×20′ container, and 20-24 tons in 1×40′ container.
