| High Light | Bolt Connection Easy Assembly ，Quick Install Steel Building ，Prefab Modular Steel Construction | ||
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.
| Main Frame | Q355B H-section welded members, factory painted |
| Connection System | Grade 10.9 high-strength friction-grip bolts, M16-M30 |
| Secondary Members | Q235B galvanized C/Z purlins, pre-punched holes |
| Bracing System |
Cross bracing with tension rods, portal frame knee braces |
| Roof Cladding | 0.5mm color steel with EPS/rock wool sandwich panels |
| Wall Cladding | 0.5mm corrugated color steel sheet, insulated optional |
| Wind Resistance | Up to 180 km/h (engineered per site conditions) |
| Seismic Grade | Grade 8 |
| Clear Span | Up to 48m single-span, unlimited multi-span configuration |
| Service Life | 50 years with standard maintenance |
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.
