Features

When using hot-dip galvanized high-strength bolts for building structures, the approval of the Minister of Land, Infrastructure, Transport and Tourism is usually required for each building structure.
However, we have obtained the certification of “Hot-dip galvanized high-strength bolt joint” from the Minister of Land, Infrastructure, Transport and Tourism. Therefore, when using our hot-dip galvanized high-strength bolts (GH bolts) and designing and constructing in accordance with the “design and construction guidelines” and “construction management guidelines”, individual certification for each property is not required. You can use it freely.
Hot-dip galvanized high-strength bolts have the following features.

• The amount of plating adhered is 550 g / ㎡ or more, and it has excellent long-term rust prevention.
• Since the nut is plated after threading, rust prevention on the threaded part is sufficiently ensured.
• The strength of the bolt is highly tough and stable.
• Since the nut is lubricated after plating, the torque coefficient value is stable and the workability by the nut rotation method is excellent.
