We upgrade this KBK rails again, which is just close to the Demag quality level:
1, Steel material: Q355B, while the tradtional is Q235;
2, Surface treatment~~ we will do the shot blasting before power coating, which will be of much better surface and the work life.
3, All the welding work are by robot, which is of better welding quality.
