Description

Quick Assembly Bolted Steel Structure Building

The KXD STEEL bolt-connection prefabricated steel structure building is engineered for maximum site efficiency. All primary and secondary members arrive at the job site pre-cut, pre-drilled, and labeled — eliminating on-site welding, cutting, and grinding. Your crew simply bolts everything together following the numbered assembly drawing.

This easy installation system reduces on-site labor by up to 40% compared to traditional welded steel construction, making it the preferred choice for projects with tight timelines or remote locations where skilled welders are scarce.

Key Advantages of Bolt Connection

  • 100% Pre-Drilled Components: Every bolt hole is CNC-drilled at the factory with ±0.5mm precision — zero on-site drilling required.
  • Numbered Part Identification: Each steel member carries a unique ID tag matching the assembly drawing for foolproof erection.
  • High-Strength Grade 10.9 Bolts: All connections use torque-controlled HSFG bolts, ensuring consistent joint performance.
  • Welding-Free Assembly: Entire structure assembled with bolts and screws — no welding permits, generators, or NDT testing needed on site.
  • Rapid Erection Timeline: Typical 1000m² warehouse frame erected in 7-10 days with a 6-person crew.
  • Dismantle & Relocate Ready: Bolted connections allow full disassembly and relocation — protecting your investment.

Easy Installation Process

  1. Foundation Preparation: Cast anchor bolts per our supplied layout drawing — completed by your local contractor.
  2. Column Erection: Position and bolt H-section columns to embedded anchor bolts with leveling nuts.
  3. Rafter Assembly: Assemble roof trusses on the ground, then lift into position with a mobile crane.
  4. Purlin & Girt Installation: Bolt pre-punched C/Z purlins to the frame — no cutting or drilling needed.
  5. Bracing & Tie Rods: Install cross bracing and knee braces following the numbered assembly diagram.
  6. Cladding Fixing: Attach roof and wall panels with self-drilling screws and integrated washers.
  7. Trim & Flashings: Install ridge caps, corner flashings, and gutter systems to complete the weathertight envelope.

FAQ

Q: Can your crew assemble this without specialized tools?
A: The only specialized tool needed is a torque wrench for critical bolted connections. Standard hand tools and a mobile crane handle the rest.

Q: Do you provide a bill of materials with bolt schedule?
A: Yes, every order includes a complete BOM with bolt grades, quantities, and torque specifications.

Q: What if we need to expand the building later?
A: Bolted steel frames are inherently expandable — we design end frames to accept future bay additions.

Q: Can the structure withstand hurricane-force winds?
A: We engineer all connections and bracing per your local wind code. 180 km/h is standard; higher ratings are available on request.
