The overall framework of the membrane structure carport is made of square steel welded into a rigid frame, which is then treated for rust prevention with three coats of anti-rust primer. The surface is coated with white automotive paint. The main pillars of the carport are typically made of 220mm steel pipes or I-beams to serve as the supporting columns. The entire structure of the carport is sturdy, seismic-resistant, and wind-resistant with high corrosion resistance.
