Rust is the most common problem in steel structure sun room. No one can guarantee that the steel structure will never rust, and it can only be delayed by paint treatment. The paint treatment methods of steel structure sun room include painting, spray painting, zinc plating, fluorocarbon spraying and so on.
The most common process of steel structure in sun room is painting and painting, and it began to rust in less than one year. The reason may be that the original rust was not sanded or the paint was too poor. Before welding the steel structure of the glass room, the original rust must be polished, and then the primer should be sprayed twice. After welding, the joints should be polished, brushed with putty, polished again, and finally sprayed with two layers of prepared topcoat. This treatment can ensure that the steel structure of the sun room will not rust for three to five years.
