304 material is corrosion-resistant and rust-proof, and is not afraid of humid environments (such as underground garage elevator entrances). The panel thickness is 0.8-1.2mm. It is reinforced with keels, and the structure is stable and resistant to deformation. We provide door-to-door measurements, customize the plan according to the door opening size and wall material, and quickly produce it in 7-10 days. A professional team will come to install it, and the joints will be even and without hollows.
