Construction-related products: hot-dip galvanized high-strength hex bolts

Construction-related products: hot-dip galvanized high-strength hex bolts

It has undergone examination based on the Building Standards Act and has obtained general certification from the Minister of Land, Infrastructure, Transport and Tourism.

The high-strength hex bolts with hot-dip galvanized coating from Teikoku Seibou Co., Ltd. have undergone examination based on the Building Standards Act regarding corrosion resistance, mechanical properties, tightening function, delayed fracture characteristics, and construction performance, and have obtained general certification from the Minister of Land, Infrastructure, Transport and Tourism. The coating weight of the bolts, nuts, and washers is over 550g/m². Furthermore, the coating weight of the components is managed under the same standards, ensuring maintenance-free corrosion resistance over the long term. In the zinc plating process, we avoid pickling as much as possible to prevent hydrogen intrusion, eliminating concerns about delayed fracture. The nuts are treated with a special lubrication process, guaranteeing stable axial force during tightening construction using the nut rotation angle method. *For urgent or emergency cases, or for technical inquiries, please contact us directly through our website.*
