Applications
Power Plants and Transmission Towers: Used in steel frameworks of thermal power plants, substations, and high-voltage transmission towers to resist industrial atmospheric corrosion and withstand sustained loads.
High-Rise Building Frames: Critical fasteners in primary steel structure beam-column connections of skyscrapers, providing reliable tensile and shear connections for building stability.
Large-Scale Industrial Facilities: Employed in roof trusses, platforms, and equipment supports of heavy-duty plants like petroleum refineries and steel mills, ensuring connection longevity in corrosive environments.
Stadiums and Long-Span Spatial Structures: Suitable for grid structures of large public buildings such as airport terminals and stadium roofs, meeting demands for high strength and durability at complex joints.
Crane Runway Systems in Heavy Industrial Plants: Specifically used to secure crane girders and brackets supporting heavy-duty overhead cranes, providing high strength and vibration resistance for operational safety.
Frequently Asked Questions
Compliance with Standards and Traceability: Does the product comply with the ASTM A325 standard, and is there traceable quality assurance?
Yes, the product fully complies with ASTM A325 standard requirements for high-strength structural bolts and provides material test reports to ensure performance traceability.
Corrosion Resistance and Service Life: What is the thickness and uniformity of the hot-dip galvanized coating, and how long is its anti-corrosion service life?
The hot-dip galvanized coating typically achieves over 85μm thickness with uniform coverage, providing long-term anti-corrosion protection for over 20 years in standard industrial atmospheric environments.
Mechanical Property Grade: What is the specific strength grade of the bolts, and for what load-bearing applications are they suitable?
Typically A325 Type 1 or Type 3, offering minimum tensile strength of 120 ksi, specifically designed for critical load-bearing connections in steel structures.
Size Specifications and Supply: Are all the nominal diameters and lengths required for the project available, and is the delivery lead time stable?
