We deliver fully engineered structural solutions for extensive commercial applications. The project shown above is a multi-span commercial and self-storage complex, demonstrating our capacity for large-scale, standardized PEB production.

• Structural System: Optimized multi-span portal frames minimizing steel tonnage while maximizing clear-span internal volume.
• Enclosure System: Equipped with a 360-degree seamed standing roof system, eliminating exposed fasteners to ensure absolute water tightness across massive roof areas.
• Standardization: Highly standardized bays and rolling-door framed openings allow for rapid on-site erection and immediate commercial operation.

Structural integrity begins with workshop tolerances. Our quality management system is strictly ISO 9001:2015 certified, ensuring full traceability from raw steel plate to the final bolted connection.

• CNC Machining Tolerances: All connection plates and splice nodes are processed using multi-axis CNC drilling machines. Hole diameter tolerances are strictly controlled within ≤ ±0.5mm, ensuring zero-force fitting for 10.9s High-Strength Friction Grip (HSFG) bolts on site.
• Node Detailing: The physical mockup above demonstrates our precise detailing for rigid connections. Web stiffeners and flange continuity plates are cut and welded to exact structural engineering specifications to prevent localized buckling.

Our fabrication facilities are designed to handle heavy industrial requirements that exceed standard light-gauge PEB limits.

• Heavy Lifting Operations: The workshops are equipped with heavy-duty double-girder overhead bridge cranes (up to 50t - 100t capacity) and supplemented by mobile cranes (e.g., SANY 50t) directly inside the shop. This allows us to handle, flip, and assemble massive built-up columns and heavy crane beams safely and efficiently.
• Automated Welding Lines: Built-up H-beams undergo continuous double-sided Submerged Arc Welding (SAW), ensuring deep penetration and minimizing heat-affected zone (HAZ) distortion.

Fabricating heavy steel is only half the challenge; delivering it globally requires specialized logistics.

• Oversized Plate Girders: As shown, we regularly fabricate and transport oversized plate girders and transfer beams with lengths exceeding 30 meters and single-piece weights surpassing 40 tons.
• Export Loading Configurations: For international EPC projects (particularly in the Middle East and Africa), our logistics engineering team designs custom loading plans. Oversized girders are secured on Flat Rack (FR) or Open Top (OT) containers, while standardized PEB frames are meticulously nested into 40HQ containers to maximize payload and reduce shipping costs per ton.
