How to treat the weld after welding?
A: Apply zinc spray or anti-rust paint to prevent rusting at the weld.
Can it be bent? What is the minimum bending radius?
A: Cold bending is possible. The minimum bending radius is usually 1-2 times the thickness of the sheet metal (perpendicular to the coating direction).
Can it be painted? What treatment is required before painting?
A: Yes, degreasing and rust removal are necessary (if the coating is damaged). Phosphating may be necessary to enhance adhesion.
Can it be cut? What are the cutting methods?
A: Yes, laser cutting, plasma cutting, and shearing are recommended. Avoid flame cutting (it easily damages the coating).
How to judge the coating adhesion?
A: Perform a bending test (180° fold). If the coating does not peel or flake, it is considered合格 (qualified).
