9. USA Standard stainless steel welding stud bolts (ANSI/AWSD 1.6)
10. Japanese Industrial Standards Cheese head studs for arc stud welding (JISB 1198)
In the same way, the company also produces according to customer's requirement like standard or special big diameter and big length high strength bolts, hexagon nuts, foundation bolts, double thread ends studs, thread rods, rail tie-in bolts and welding bolts, studs, pins, riveted fasteners which supply for vessels or boilers industry line. In addition, we can satisfy the requirement for the surface finish, for example: phosphated, hot dip galvanized, mechanical galvanized, sherardizing, dacromet and Teflon, etc.
Among above-mentioned products, torshear high strength hexagon head with flange bolts, nuts and plain washers was our company’s patented products. They not only have the advantages of convenient handling, easy visual inspection, and high efficiency during construction but also convenient dismounting, and can use torque method to recheck if the bolts have been well fastened. These features have solved the problem of difficult fastening at the corner of the steel structure and prevented the potential risk of head broken caused by the indentation on the head shank of the washer.
The type of the company which is mainly engaged in: dacromet processing, chromium dacromet (green), multicomponent alloys permeation (infiltration of zinc), thermal spray zinc (aluminum), its power coating (green), heavy-duty composite coating that can satisfy all kinds of fields widely different anti-corrosion class requirements, environmental protection and special requirements.
