1. The material of aluminum will not rust than the steel, and surface anodizing is more beautiful than hot-dip galvanizing on iron surface.

2. The products of aluminum carport is more light, in normal situation, just 2-3 workers and one forklift can finish the installation, but steel carport basically need a crane, will increase the installation fee.

3. The aluminum carport products have regular shapes, which are convenient for sorting and arranging in pallet and put in container, can maximize the use of container space when loading the container, also can reduce the quantities‌ and shipping fees of container. However, there are many special-shaped parts in the steel carport, many products are difficult to load the unload. It's easy to damage the products during loading and unloading, and they can not be placed according to specifications. The utilization rate of containers is very low, and sometimes only a few parts can be placed in one container, which will increase the freight cost and the cost of the projects.
