Industrial Fasteners Manufacturer, Wholesaler, Supplier & Exporter for Construction & Infrastructure
Structural bolts, anchor bolts, and general-purpose fasteners for building construction, steel structures, and civil infrastructure projects.
What Construction & Infrastructure Buyers Need
- High-tensile structural bolt assemblies (HSFG) for steel frames
- Foundation and anchor bolts to project drawings
- Hot-dip galvanized fasteners for outdoor and coastal exposure
- Project-scale bulk supply with mill test certificates
Common Challenges
Project delays from fastener shortages
A missing bolt grade or size can hold up an entire structural erection schedule.
Certification gaps
Structural sign-off requires mill test certificates that generic hardware suppliers often can't provide.
How We Help
Project-based bulk quoting
Full bill-of-materials quoting against structural drawings, with certified documentation.
Galvanizing on request
Hot-dip galvanizing available for outdoor and coastal structural work.
Standards & Grades for Construction & Infrastructure Fasteners
The specifications construction & infrastructure buyers most often quote. Our partner factories manufacture to the standard, grade and finish on your drawing or purchase order.
EN 14399 / ISO 7412 HSFG assemblies
High-strength friction-grip bolt, nut and washer sets for preloaded steel-frame connections.
ASTM F3125 (A325 / A490)
Heavy hex structural bolts for steel buildings and bridges built to US specifications.
ASTM F1554 anchor bolts
Foundation anchor rods in grades 36, 55 and 105, cast into concrete to hold columns and equipment.
ISO 1461 / ASTM A153 hot-dip galvanizing
Zinc coating thickness standards for fasteners exposed outdoors, in coastal air or in wet concrete.
Materials & Coatings
Carbon & alloy steel
Medium-carbon steel for grades 8.8 and A325, alloy steel for 10.9 and A490 structural assemblies.
Hot-dip galvanized finish
Thick zinc layer for exposed steelwork, bridges, towers and coastal buildings; threads are cut or tapped to suit the coating.
Stainless steel 304 / 316 anchors
For facades, tunnels and marine-exposed concrete where galvanizing alone would not last the design life.
