PURLINS & GIRTS SYSTEMS
Our cold-formed steel purlins include C-section and Z-section profiles from 150mm to 350mm depth for roof and wall framing. Spans from 4m to 10m depending on loading and profile selection. Manufactured from high-tensile steel (G450) to AS/NZS 4600 with BMT from 1.5mm to 3.0mm. Galvanized Z275 coating for corrosion resistance. Continuous purlins with sleeved joints for long-span applications. Eaves beams and gable posts for complete building frame. Load-span tables and design software available.
ACCESSORIES & INSTALLATION
Complete purlin systems including cleats, brackets, and bolted connections. Anti-sag rods and struts for stability during construction. Bridging channels for diaphragm bracing. Thermal breaks for insulated buildings. Sleeved joints for continuous spans. Fly bracing and tie-down systems for cyclonic regions. Pre-punched holes for services penetrations. Site delivery with crane truck placement. Installation crews available for complete erection. Engineering certification for building consent.
DESIGN SUPPORT
Our structural engineers provide purlin design, spacing calculations, and connection details to AS 4100 and AS/NZS 4600. Wind load analysis for site-specific conditions. Seismic design for earthquake zones. Deflection checks for cladding compatibility. Thermal movement calculations. Complete shop drawings and erection plans. Material take-offs and cost estimates. Technical support during construction. Volume pricing for commercial and industrial buildings with flexible payment terms.
