The electronic truck scale adopt box structure, submerged arc welding, dioxide protect welding. The weighing platform is rigid enough to be inflexible. Before painting, we do shot blasting and burnish to increase adhesive force. After this step, we paint anti-corrosive primer and acrylic polyurethance coating. To increase the protecting ability of platform, hot zinc spraying is necessary.
Superiority of zinc treatment is:
1、 Long lasting: in general situations, hot galvanizing coat can prevent the generation of corrosion. And this superiority gets reflected especially in coastal areas.
2、 Good reliability: galvanized coat and steel is metallurgical bonding. Thus it is more durable.
3、 Strong toughness of galvanized coat: the galvanized coat is a special metallurgical structure, which make the scale body have more strong bearing capacity to avoid mechanical damage while transporting and using.
4、 Universal precaution: every part of scale be galvanized, even in dents, sharp corner and stash.
