EN 14399-3-2015 High-strength structural bolting assemblies for preloading-system HR-Hex bolt
Product details
High-strength structural bolting assemblies for preloading - system HR-Hex bolt specifications range from M12 to M36, with a pitch varying from 1.75mm to 4mm.The surface is treated with hot-dip galvanizing to enhance corrosion resistance.
Product Characteristics
- High strength: Designed to withstand high preloads, ensuring the stability and safety of the connection.
- High precision: the dimensions, tolerances and mating accuracy of bolts and nuts meet standard requirements to ensure interchangeability and assembly performance.
- Corrosion resistance: Some products have been hot dipped zinc and other surface treatment to improve corrosion resistance in harsh environments.
- Systematic: As part of the HR system, it works together with supporting nuts, washers and other components to form a complete connection system.
ApplicationThey are widely used in the field of construction, bridge, tower and other steel structures, for connecting steel structure components, such as the connection of steel structure frame, the fixing of wall panels, the connection of the main beam of the bridge with the beam, the longitudinal beam, and the connection of the support structure of the tower, the platform, etc.
- Building steel structure: used for steel structure connection of large buildings such as Bridges and high-rise buildings.
- Mechanical equipment: plays an important role in the structural connection of heavy machinery, wind power equipment and other fields.
- Infrastructure: In the construction and maintenance of infrastructure such as railways, roads and ports, it is used to connect key structures.
