Donald McwayneGood team members always offer budget in time and answer questions with patience, great job! -
Joseph AlexanderI am feeling fully respected when taking with Grace and she always gave the best advice. The first batch of the bridge panels got are great too. thanks all.

Why AISC Compliance Matters for Your Workshop
AISC 360 is the most widely recognised structural steel standard for building construction in North America and many international markets. By specifying an AISC-compliant truss, you gain:
-
• Structural integrity – proven design methodology for strength, stability, and serviceability
-
• Seismic resilience – AISC 341 provisions available for earthquake-prone regions
-
• Design flexibility – standardised connection details and member design criteria
-
• Code acceptance – recognised by building officials and inspectors worldwide
-
• Quality assurance – fabrication tolerances and inspection requirements are clearly defined
For large-span workshops – where structural failure would pose significant safety and operational risks – AISC compliance provides the engineering confidence your project demands.
Engineered for Large-Span Workshops
Large-span workshops present unique structural challenges that our custom steel truss addresses directly:
• Column-Free Interiors
Workshops require unobstructed floor space for production lines, heavy equipment, and material flow. Our truss designs achieve spans of 30–60+ metres without intermediate columns, maximising usable floor area and operational flexibility.
• Heavy Load Capacity
Workshops support significant loads: overhead cranes (5–50+ tons), roof-mounted HVAC, exhaust systems, fire sprinklers, and maintenance loads. Our trusses are engineered to handle these combined load conditions with appropriate safety factors.
• Design Flexibility
Every workshop layout is different. We offer multiple truss configurations – Warren, Pratt, Howe, or custom lattice – and can integrate with your existing column grid, roof slope, and building envelope requirements.
• Future Adaptability
AISC-compliant detailing allows for future modifications – mezzanine floors, additional crane capacity, or building extensions – without major structural changes.
Custom-Engineered – Built to Your Exact Specifications
We don't offer one-size-fits-all. Every truss is custom-engineered to match your project requirements:
-
• Span length – matched to your building dimensions (15–60+ metres)
-
• Roof slope – single pitch, double pitch, or flat as required
-
• Member sections – H-beams, channels, angles, or tubes optimised for structural efficiency
-
• Connection details – bolted field connections (preferred) or shop-welded
-
• Load conditions – dead, live, snow, wind, seismic (AISC 341 available)
-
• Crane integration – provisions for overhead bridge and gantry cranes
-
• Surface treatment – shop primer, paint system, or hot-dip galvanized
Engineering Deliverables:
-
• 3D models (Tekla Structures / STAAD Pro)
-
• Detailed shop drawings with dimensioned members
-
• Erection plans with step-by-step assembly sequence
-
• Connection details for field bolting
-
• Material take-offs and lifting plans
Material Selection – Quality Steel, Fully Traceable
We manufacture our AISC-compliant trusses from premium structural steel grades:
| Grade | Standard | Yield Strength | Application |
|---|---|---|---|
| ASTM A572 Grade 50 | ASTM A572 | 345 MPa (50 ksi) | Heavy‑duty, large‑span – preferred for AISC projects |
| ASTM A992 | ASTM A992 | 345 MPa (50 ksi) | Wide‑flange shapes – superior weldability |
| Q355B | GB/T 1591 | 355 MPa | Equivalent to A572 Gr.50 – international projects |
Full Mill Test Certificates (MTCs) with heat number traceability are provided with every order, ensuring complete material transparency.
Fabrication to AWS D1.1 – Quality You Can Trust
All fabrication is performed in our facility to AWS D1.1 Structural Welding Code requirements:
CNC Cutting & Drilling
Precision equipment ensures exact member lengths and accurate bolt hole positions to AISC Code of Standard Practice tolerances.
Jig-Set Assembly
Components are assembled on purpose-built jigs to maintain consistent geometry across all trusses.
Certified Welding
All welding is performed by AWS D1.1 certified welders using approved WPS (SMAW/GMAW/SAW).
Inspection & Testing
-
• Dimensional verification against shop drawings
-
• Visual inspection of all welds
-
• NDT (UT/MT) on critical joints as required
-
• Coating thickness verification
Trial Assembly – available for complex projects to verify fit before shipment.
Quality Assurance – AISC Code Compliance
We maintain a rigorous quality system aligned with AISC requirements:
-
• Design Verification – all designs reviewed by qualified structural engineers
-
• Material Traceability – MTCs with heat numbers for every component
-
• Welding Quality – AWS D1.1 certified welders and approved WPS/PQR
-
• Fabrication Tolerances – per AISC Code of Standard Practice (length ±2mm, straightness ≤L/1000)
-
• NDT Inspection – UT/MT as required by project specifications
-
• Third-Party Inspection – we welcome SGS, BV, TÜV, or your chosen inspector
Complete documentation provided with every shipment: MTCs, WPS/PQR, NDT reports, dimensional records, and as-built drawings.
