Structural System Breakdown
Main Structural Frame
- High-strength structural steel rigid frame with heavy-duty bolted splice joints.
- ASTM A325 or A490 (or Grade 8.8 / 10.9) high-strength bolt connections for superior joint moment capacity.
Composite Floor System
- Galvanized profiled steel decking sheet acting as permanent formwork.
- Welded shear studs (headed anchors) combined with reinforced concrete mesh for a high-load 100–150mm composite slab system.
Wall & Envelope Cladding
- Insulated Sandwich Panels: Polyurethane (PU / PIR), High-density Rockwool (for strict fire ratings), or EPS.
- Single-skin color-coated architectural steel sheets with anti-capillary side laps.
High-Performance Roof System
- Pre-engineered insulated roof standing-seam systems for 100% waterproof performance.
- Integrated industrial skylights, continuous ridge ventilators, and heavy-duty flashing/gutter systems.

Frequently Asked Questions
Q: What support do you offer for the installation phase overseas?
A: We provide a complete installation documentation pack, which includes detailed anchor bolt layouts, 3D structural tracking diagrams, and a step-by-step erection manual matching the codes stamped on the physical steel components. Additionally, we provide dedicated remote technical video support, and can deploy senior installation engineers to your job site for on-site guidance if required.
Q: Can your designs be used to obtain local building permits?
A: Yes. We provide comprehensive structural calculation sheets, detailed Tekla shop drawings, and stamped engineering documentation aligned with your requested local building codes (AISC, Eurocodes, BS, or GB) to facilitate smooth approvals with local building authorities.
Q: Can your multi-floor structures support heavy automated racking systems?
A: Absolutely. Our engineering team custom-calculates floor load designs from 2.0 kN/m² up to 20.0+ kN/m² to fully support automated storage and retrieval systems (AS/RS), heavy forklift traffic, and industrial machinery.
Q: How much faster is steel construction compared to traditional concrete?
A: Generally 30% to 50% faster. Because all structural members are pre-fabricated, CNC-drilled, and cut in our factory, on-site execution is reduced to a clean, bolt-together assembly process.
Q: What is the typical structural lifespan of a Wanxiang steel warehouse?
A: Our structures are engineered for a service life of 30 to 50+ years, depending on environmental factors and routine surface maintenance.
