Roofing & Steel Structures
Complete steel roof structures — portal frames, trusses, purlins, and sheeting rails — fabricated and supplied ready for cladding, including agricultural and industrial spans.
What This Service Covers
We fabricate complete roof structure packages: portal frames, roof trusses, purlins, girts, and bracing, sized for your span, wind load, and roof sheeting profile.
For agricultural and industrial buildings we routinely supply clear-span structures up to 30 m without internal columns, engineered for regional wind and snow loading where applicable.
Structures are supplied piece-marked with an erection drawing, and we coordinate directly with roof sheeting and cladding installers to keep purlin spacing and fixing points aligned to the sheeting profile.

How We Deliver This
Every job runs through the same sequence — nothing skipped to hit a date.
Load & Span Assessment
Span, wind zone, and roof loading confirmed against SANS 10160 or applicable code.
Frame Design
Portal frame and truss geometry engineered or verified for the confirmed loads.
Fabrication
Columns, rafters, purlins, and bracing cut, drilled, and welded in-shop.
Coating
Shot-blast and primer, or full hot-dip galvanizing for exposed agricultural structures.
Erection Support
Delivered piece-marked with erection drawings; site erection crew available.
Roofing & Structures — Frequently Asked
Yes, we work with structural engineers to size portal frames and trusses for your span and local wind loading, or coordinate directly with your appointed engineer if you already have one.
