AS4100 Designed Steel Frames for Industrial Plants and Warehouses

We design and fabricate AS4100 Designed Steel Frames for industrial plants and warehouses. From portal frames to bracing systems, every frame is engineered to meet Australian structural design requirements and built with certified steel for heavy loads, clear spans, and long-term durability. Our prefabrication approach means frames arrive ready for fast installation, helping you save site time and construction costs. We also provide design support, quality documentation, and export services to ensure a smooth project from start to finish.

AS4100: More Than a Standard—It's Your Safety Baseline​

• • Design Compliance: Every frame is designed to AS4100 for structural safety and reliability under ultimate limit state and serviceability limit state.

• • Load Considerations: Design accounts for dead loads, live loads, wind loads, seismic actions, crane loads, and equipment loads.

• • Structural Analysis: We use advanced structural analysis to check member forces, deflections, stability, and connection design.

• • Optimized Sections: Steel sections are selected to balance strength, weight, and cost efficiency, reducing steel consumption without compromising safety.

• • Design Documentation: Design calculations, structural drawings, and compliance statements can be provided for project approval.

• • Peace of Mind: You get a frame that meets Australian standards and performs under real-world demands, including fatigue and dynamic loading.

Frames That Fit Your Plant, Not the Other Way Around​​

• • Custom Spans: Large clear spans for warehouse storage, production lines, and logistics operations, with tailored column spacing.

• • Flexible Heights: Frame heights tailored to crane systems, mezzanines, ventilation needs, and future expansion.

• • Structural Options: Portal frames, trusses, box columns, H-section columns, and built-up sections for different load requirements.

• • Secondary Members: Purlins, girts, ties, roof bracing, and wall bracing for complete structural systems.

• • Connection Details: Base plates, gusset plates, stiffeners, and bolted connections for easy assembly and reliable load transfer.

• • Crane Systems: Crane beams, brackets, and columns designed for overhead cranes and monorail systems.

• • Mezzanine Support: Mezzanine beams, columns, and floor decking integration for multi-level industrial spaces.

• • Expansion Capability: Bolted connections and modular design allow for future expansion without major rework.

Prefabrication: The Smart Way to Build Industrial Steel Frames​​

• • Workshop Production: Frames are fabricated in a controlled environment for consistent quality, accurate dimensions, and efficient production.

• • Trial Assembly: Pre-assembly confirms fit-up, alignment, hole positions, and dimensional accuracy before shipment.

• • Welding Quality: Qualified welding procedures and certified welders ensure strong connections and compliance with AS/NZS 1554.

• • Bolted Connections: High-strength bolted connections are prepared for fast site assembly and reduced on-site welding.

• • Surface Protection: Shot blasting, painting, or hot-dip galvanizing for corrosion resistance and long service life.

• • Marking & Packing: Each component is clearly marked with piece numbers and packed for easy identification and efficient site handling.

• • Site-Ready Delivery: Frames are packed and marked for fast unloading and efficient installation, with shipping marks matching erection drawings.
