Engineered Steel Solutions for Melbourne’s Growing Infrastructure

At A.C. Steel, we deliver code-compliant, heavy-duty structural steel solutions tailored for commercial and industrial construction projects across Melbourne and regional Victoria. Whether you’re building a warehouse, factory, or distribution centre, we provide full-service fabrication and installation — engineered for scale, speed, and strength.

We partner with builders, architects, and project managers to meet tight deadlines, coordinate site-specific challenges, and ensure every steel component is precision-built to withstand long-term operational demands.

Full Portal Frame Systems

We fabricate and install complete portal frame systems, engineered for large clear-span areas without internal columns — ideal for warehouses, distribution centres, and production floors.

  • Engineered to handle wind loads, seismic activity, and roof loads
  • Designed for efficient installation with bolted connections and pre-cut baseplates
  • Fully integrated with purlins, bracing, and roof support systems

Customised for wide-span coverage and overhead crane compatibility if required

Structural Columns, Beams & Bracing

Our industrial-grade columns and beams provide a robust load-bearing framework that supports multi-level structures, mezzanines, and heavy plant installations.

  • Available in standard or custom lengths and profiles (UB, UC, PFC, RHS)
  • Bracing systems designed to resist lateral forces and meet wind rating requirements
  • Accurate positioning of cleats and welded connections for seamless site assembly

Elevated Walkways & Equipment Platforms

Many industrial facilities require safe access systems and working platforms — we provide elevated steel walkways, mezzanines, and platforms designed for functionality and compliance.

  • Anti-slip grating, handrails, and kick plates available
  • Load-rated to support personnel and machinery
  • Fabricated for seamless integration with existing equipment and layout

Engineered per AS 1657: Fixed Platforms, Walkways, and Ladders

Mezzanine Floors & Internal Steel Structures

Our steel-framed mezzanines offer a cost-effective way to maximise usable floor space in warehouses and workshops.

  • Freestanding or integrated mezzanine structures
  • Designed for racking, offices, or operational zones
  • Structural steel supports for stairwells, service risers and internal platforms
  • Customised height, span, and point load specs as per client needs

Quality, Speed, and Design Collaboration

  • Fast lead times – ideal for industrial builders managing tight construction windows
  • In-house CAD drafting – allowing us to accommodate complex floor plans and services
  • Clean, architectural-grade finishes – perfect for projects requiring exposed steel elements
  • Seamless site coordination – working directly with builders, project managers, and other trades

Industrial Structural Steel — Frequently Asked Questions

Specialist answers for warehouse developers, factory owners, and industrial builders sourcing heavy structural steel in Melbourne.

What's the typical cost for an industrial portal frame in Melbourne?
Industrial portal frame pricing depends on span, eave height, crane rating, wind region (Melbourne is typically N3), cladding integration, fire rating requirements, and site access — every job is quoted individually. For warehouses of any size we can provide concept tonnage estimates from preliminary drawings, with full tender pricing requiring your structural engineer's drawings. Email your drawings or RFQ to info@acsteelconstruction.com.au or call 0431 885 854.
What's the maximum span and eave height for a warehouse portal frame?
Maximum spans and eave heights depend on your engineer's design loads (dead, live, wind, snow if applicable, crane impact) and the chosen steel section. We fabricate portal frames to AS 4100 and AS/NZS 5131 standards across the typical range used in Australian industrial construction. For larger or taller configurations, multi-span or modular designs allow us to extend beyond standard single-bay limits. Send us your concept drawings or design brief and we'll confirm what's achievable.
Can you design and fabricate crane runway steel for industrial facilities?
Yes — crane runway systems are a specialty. We fabricate top-running crane runway beams, under-running monorails for lighter loads, crane stop bumpers and end-of-travel safety, runway support brackets and columns with impact-resistant connections, and we coordinate runway alignment and surveying post-installation. Crane runway design must account for impact loads, lateral forces, and fatigue per AS 1418 and AS 4100. We work with your crane supplier to ensure the runway matches the crane's wheel base, wheel loads, and runway profile.
How are industrial mezzanines designed for high load capacity?
Industrial mezzanines for storage, manufacturing, or racking systems require careful design covering floor load capacity (specified per use — e.g., light storage versus racking versus heavy machinery), point load capacity (critical for racking), forklift access with reinforced edge beams and impact protection, stair design to AS 1657, fall protection per AS/NZS 1657, and fire egress per the NCC for your building class. We provide complete mezzanine packages including design coordination with your engineer, fabrication, installation, racking integration, and compliance documentation. Lead time varies by size and complexity — contact us with your concept drawings for current timeframes.
Do you offer hot-dip galvanising for outdoor industrial structures?
Yes — hot-dip galvanising is widely used for outdoor industrial steel exposed to weather, chemicals, or coastal salt air. The process involves designing for galvanising (drainage holes, vent holes, avoiding welded enclosures that can trap gas), coordinating fabrication with a galvanising plant compliant with AS/NZS 4680, post-galvanising assembly with galvanised fasteners, and touch-up coatings (zinc-rich paint) for any damage during transport or installation. Galvanising adds cost but significantly extends steel life in industrial environments — recommended for portal frames, mezzanines, walkways, and any outdoor structural steel. We can quote with and without galvanising for comparison.
What compliance documentation do you provide for industrial builds?
For industrial projects we provide a complete documentation package: mill certificates (AS/NZS 3679.1 compliant steel grades), weld procedure specifications (WPS) per AS/NZS 1554.1, welder qualifications (SP / GP / GPL as required), shop drawings with all dimensions, connections, and weld symbols, erection drawings with installation sequence and torque values, non-destructive testing (NDT) reports for critical welds where specified, hot-dip galvanising certificates where applicable (per AS/NZS 4680), erection certification signed by a competent person, and as-built drawings post-installation. Documentation is provided in PDF and DWG formats. Suitable for CC2-CC4 projects per AS/NZS 5131.
Can you fabricate forklift impact-resistant steel reinforcement?
Yes — forklift impact zones in warehouses and factories require specific reinforcement strategies including bollards and barriers (heavy gauge tube steel, foundation-bolted, painted high-visibility), column protection guards (wrap-around plate design), edge protection rails for raised areas, loading dock leveller frames with reinforced anchor points, and mezzanine edge protection per AS 4084 for racking environments. Many industrial clients spec impact protection as part of the original warehouse or mezzanine package — designing it in early avoids costly retrofits. We can also retrofit protection to existing facilities without disrupting operations.
How do you handle deliveries and installation at operational industrial sites?
Active industrial sites require careful coordination. Our process: pre-installation site survey with your facility manager (clearances, access routes, lift zones); site induction (our crew completes your site's WHS induction); appropriate Personal Protective Equipment per industrial standards; hot work permits coordinated with your site for welding and grinding; staged delivery in installation sequence to avoid on-site storage; after-hours work for 24/7 operations to minimise operational disruption (premium applies); confined space and working-at-heights compliance with our crew qualified and JSAs prepared in advance. For high-risk industrial environments such as food, chemical, or pharmaceutical sites, we follow your specific contamination control protocols.
