Light steel frame buyer guides
Light steel roof trusses explained for buyers
What a light steel roof truss is, how a roof system is layered on top of it, what the Digital Oro catalog lists, and what to confirm before ordering.
The roof is one of the most engineered parts of a steel-framed building. This guide explains the parts so a buyer can ask good questions. See also steel roof trusses: procurement questions.
What the catalog lists
| Roof element | As shown in the catalog |
|---|---|
| Truss | Light steel roof truss |
| Batten | 35 mm steel batten for the roof |
| Purlins | Roof purlins are shown alongside the batten |
| Reinforcing layer | OSB board, 15 mm |
| Layers | Waterproof layer, vapor barrier, insulation layer, fascia board |
What to confirm
- Span, pitch, spacing and design loads (wind, snow, dead and live) used in the truss design.
- Steel grade, thickness and coating of the truss members, and the standard they follow.
- Connection and bracing details, and the fastener schedule.
- Delivery form: pre-assembled, panelized or flat-packed, and what handling the site needs.
- Engineer sign-off for your project and your local authority's acceptance.

Questions people ask
What is a roof truss?
A triangulated frame that carries the roof load to the walls. Light steel trusses are made from cold-formed steel sections.
What sits on top of the trusses in the catalog?
The catalog roof system lists a steel roof batten, a reinforcing layer, a waterproof layer, a vapor barrier and an insulation layer over the light steel truss.
Who designs the truss?
A qualified engineer designs it for your loads and local code. Ask for the calculations, not only the catalog drawing.
