There are five major series of our products: 1. High strength bolts with large hexagon head for steel structures (GB/T 1228-1231) 2. Sets of torshear type high strength bolt hexagon nut and plain washer for steel structures (GB/T 3632-3633) 3. High strength bolts with hexagon head and flange torque type for steel structures (QBC 1011-1014) 4. Cheese head studs for arc stud welding (GB/T 10433) 5. Big specifications of wheel nuts, nuts with washer face and nuts sets The products carried out the standard like USA (ANSI/ASME ), Germany(DIN), Japan(JIS), Britain(BS), Australia(AS) and International Standard (ISO)etc, for example: 1. USA Standard high strength bolts with large hexagon head for steel structures (ASTM A325 A490 A325M A490M) 2. USA Standard Sets of torshear type high strength bolt hexagon nut and plain washer for steel structures (ASTM E 1852) 3. Germany Standard high strength bolts for steel structures (DIN 6914-6916) 4. Japanese Industrial Standards high strength hexagon head bolts (JIS B 1186) 5. Japanese Industrial Standards high strength torque type bolts (JSS II-09) 6. British Standard high strength joints bolting (BS 4395) 7. Australia Standard high strength bolting (AS 1252) 8. USA Standard welding stud bolts (ANSI/AWSD 1.1) 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.
