TriArcSource delivers precision-engineered Light Gauge Steel Framing systems for commercial and residential construction — built to international standards, installed in record time.
TriArcSource is a specialist supplier and installer of Light Gauge Steel Framing (LGSF) building systems. We combine precision factory fabrication with rapid on-site assembly to deliver structures that outperform traditional methods in speed, strength, and cost.
From single-storey residences to multi-floor commercial buildings, our panels are engineered to exact project specifications and delivered ready for installation by our trained crews.
Light Gauge Steel Framing uses cold-formed, roll-formed steel sections to build wall panels, roof trusses, and floor systems — precise, lightweight, and structurally superior to traditional materials.
Pre-fabricated load-bearing and non-load-bearing panels using U-Stud and C-Stud profiles. Fiber Cement Board (FCB) cladding on one or both sides. Pre-punched conduit holes for services.
Engineered roof truss systems designed to span large distances with minimal internal support. Compatible with all standard roofing materials — metal, tile, and membrane.
LGS joist systems with optional Rockwool cavity insulation (40 kg/m³). Cement Fibre Board decking provides a flat, rigid floor platform for any finish material.
High-tensile steel connection brackets (powder-coated, 2.0mm) for Ell corners, inline joints, and Tee junctions. All designed per AS/NZS 4600:1996.
Z220 hot-dipped galvanized coating for load-bearing applications. Alternatively, Galvalume (55% Aluminum, 45% Zinc) for superior performance in harsh environments.
Pre-punched service holes allow electrical conduits and plumbing to pass directly through panels. Concealed flush tanks and wall-mounted WC systems are fully supported.
Our end-to-end process ensures every project is delivered on time, on spec, and with zero surprises.
Structural design, panel layout, and engineering drawings prepared to project requirements
Panels roll-formed, assembled, and quality-inspected in our controlled factory environment
Panels wrapped, labelled, and palletized by zone for efficient container loading
Containers coordinated for just-in-time delivery to match your site programme
Trained crews erect the full structural frame — often completing a house frame in days
From individual homes to large-scale government housing programmes, LGSF adapts to virtually any building type or site condition.
Single and multi-storey homes, granny flats, townhouses, and social housing. Faster frames mean earlier handover and reduced financing costs.
Offices, retail fit-outs, warehouses, and industrial facilities. Lightweight steel reduces foundation load and accelerates fitout timelines.
Schools, clinics, community halls, and government buildings. Certified structural performance that meets regulatory requirements across jurisdictions.
Emergency housing, disaster relief, and remote area builds. Flat-packed containers and minimal site equipment make LGSF ideal for challenging locations.
Every project we deliver is backed by our commitment to precision, speed, and structural integrity.
Factory fabrication and modular assembly dramatically compress construction timelines compared to traditional masonry.
Designed to AS/NZS 4600:1996 with Z220 galvanized protection — guaranteed structural integrity for 50+ years.
Reduced labour, less site waste, and faster timelines mean lower total project costs and earlier revenue for developers.
LGSF performs in tropical, temperate, and arid environments. Corrosion protection options tailored to local conditions.
We manage design, fabrication, logistics, and installation support — one partner, one responsibility, zero gaps.
All structures designed and documented to international standards, making approvals faster and inspections straightforward.
