| High-Strength Bolts | Grade 8.8, Grade 10.9 | Critical connections for structural integrity |
| Ordinary Bolts | Grade 4.8 | Secondary connections between maintenance and main structures |
| Anchor Bolts | Customized per foundation design | Securing steel columns to concrete foundations |
| Nuts & Washers | Compatible with high-strength and ordinary bolts | Bolt tightening, anti-loosening, and pressure distribution |
| Welding Materials | Electrodes (E43, E50 series), welding wires (ER50-6) | Selected to match specific steel materials |
High-strength steel construction provides excellent load-bearing capacity, durability, and resistance to wind and seismic forces. Enables creation of large-span, column-free spaces for flexible office layouts.
Factory prefabrication followed by on-site assembly significantly reduces construction time by 30-50% compared to traditional methods.
Minimal column design creates open, adaptable interiors that can be reconfigured for changing business needs.
Steel's malleability allows for creative architectural designs that enhance corporate image and create distinctive landmarks.
Comprehensive quality control throughout manufacturing process including real-time monitoring of cutting, drilling, and welding operations. Non-destructive testing (ultrasonic, magnetic particle) ensures welding quality meets design specifications.
Standard components packed in plywood boxes, welded components protected with bubble-wrap, and all materials organized on steel pallets for efficient container loading and site unloading.
