What is HV bolt of metal structure? Key standards and specifications
- Tensile strength: The maximum stress a screw can withstand before breaking.
- Shear strength: The ability of a screw to resist the forces that try to cut it.
- Strength class: A number that indicates the strength level of the screw (eg 8.8, 10.9, 12.9).
- Materials: Usually produced from high carbon steels or special alloys.
- Surface coating: Such as hot dip galvanized for corrosion resistance.
Wide applications of HV screws in various industries
1. Construction metal structures
2. Bridge building and infrastructure
4. Oil, gas and petrochemical industries
Factors affecting the price of HV screws of metal structures
- Strength class: Bolts with a higher strength class (e.g. 12.9) are more expensive than those with a lower class (e.g. 8.8).
- Alloy material: The use of special alloys or alloy steels increases the cost of production.
- Surface coating: Hot-dip galvanized or specially coated bolts are more expensive than The types are black (uncoated).
- Dimensions and length: Bigger and longer screws have a higher price due to the consumption of more raw materials.
- Production standard: Screws produced according to stricter standards and with valid certifications may be more expensive.
- Purchase volume: Bulk purchase usually comes with more discounts.
