This is an emerging type of wrought iron fence, which itself is made of all-aluminum alloy, removable, no welding, no screws on the surface. The connection is compact and there is no loose shedding. Packing, transportation and installation are easy. Fences are easy to process and economical to transport. Aluminum alloys can withstand greater tensile and impact forces, while possessing better flexibility. The surface is rich in hard aluminum oxide film, and the surface is treated with anodization in particular to make the fence highly resistant to corrosion.
