Extra-long and Extra-large Bolts
- The length of extra-long and extra-large bolts is usually more than 300mm and can reach several meters.
- The diameter is generally larger than 30mm.
- Larger sizes can be customized according to specific requirements.
- These bolts meet the requirements of special projects for connection length and strength.
- Surface Treatments: Galvanizing treatment, blackening treatment, nickel plating treatment
Materials of Extra-long and Extra-large Bolts
High-strength alloy steels such as 40Cr and 35CrMo are often used. These materials have high tensile strength, good toughness, and fatigue resistance, and can withstand huge tensile and shear forces to ensure the reliability of connections under harsh working conditions.
Application Fields of Extra-long and Extra-large Bolts
- Bridge engineering: It is used to connect large structural components of bridges, such as girders and piers, and bear the self-weight of the bridge and the loads of vehicles, etc.
- Mining machinery: In large-scale mining equipment such as crushers and mills, it is used to connect various components of the equipment to ensure the stability of the equipment during high-intensity operation.
- Building steel structures: Connect large-scale steel structure components, such as steel beams and columns of high-rise buildings and large-scale factory buildings, to ensure the integrity and safety of the steel structures.
- Wind power equipment: It is used to fix components such as the towers and nacelles of wind turbines to resist the action of natural forces such as strong winds.
