The box and material are divided into carbon steel (Q235)
Thickness is divided into 1.5mm, 2mm, 3mm and other specifications
Blanking process: using laser, tower punch, flame, plasma, coil forming and CNC bending technology
Welding process: adopt argon arc welding and gas shielded welding spot welding or break welding.
Derusting process: The entire box is degreasing and decontaminated, and the surface derusting is sandblasted to enhance the surface adhesion of the paint.
Coating process: The inner wall is made of wear-resistant and corrosion-resistant epoxy resin asphalt paint, 793 sealant is applied between the two welding seams, and the outer wall is sprayed with acrylic two-component primer and topcoat, and the thickness of the paint film is not less than 60-90μm , divided into blue and white or green and white two styles.
