Choosing a sheet
| Profile | IBR (686 mm cover) for most roofs and cladding; corrugated (762 mm) for the traditional look; concealed-fix for low pitches without exposed screws. |
|---|---|
| Thickness | 0.30 mm for sheds and outbuildings; 0.40–0.47 mm for houses; 0.50–0.80 mm for wider purlin spacings, industrial roofs and long spans. |
| Coating | Galvanised Z100–Z275 (the higher the Z, the more zinc); Zincalume® AZ150 lasts longer; colour-coated adds a factory paint finish. |
| Length | Stock lengths of 3.0, 3.6, 4.2, 4.8, 6.0 and 6.6 m; or cut to length from 1 to 14 m so each sheet runs eaves to ridge with no end laps. |
| Coast & industry | Within a few kilometres of the sea or heavy industry, use Z275, Zincalume® or colour-coated sheet and Class 4 or stainless fixings. |
The minimum pitch, purlin spacing and fixing pattern for each profile and gauge come from the maker's tables; the truss design and your drawings govern. New houses also need ceiling insulation to SANS 10400-XA.

A guide for ordering: sheets overhang into the gutter by 50 mm and lap 200 mm end to end only where a slope is longer than 14 m; tiles include 5% for breakage; underlay allows about 10% for laps. Roof screws, closures and barge flashings depend on the purlin and batten layout — your roofer or the merchant confirms them. Hipped roofs: send the plan with a quote. The truss design and your drawings govern.
Roof & structural timber
SA pine in every section below, in 3.0, 3.6, 4.2, 4.8, 6.0 and 6.6 m lengths. Pick the section, then the grade and treatment — each is sized (planed to size) or rough-sawn. The everyday S5 H2 sized sections are priced to order online; everything else is priced with the supplier on your quote, with the grade and treatment confirmed.

| H2 | Insect and borer protection for timber kept dry under the roof — trusses, rafters, purlins, ceiling battens. Never where it will get wet. The budget choice. |
|---|---|
| H3 | For timber above ground that gets wet: exposed eaves and overhangs, fencing rails, balustrades, cladding, decks, carports and pergolas, and coastal or damp sites. |
| S5 | The standard stress grade for house roofs (SANS 1783) — what most truss designs call for. |
| S7 | Stronger and stiffer, for longer spans and heavier loads — only where the truss design or engineer specifies it. Graded to order. |
| Profile | Sized timber is planed to a uniform size so members line up; rough-sawn is straight off the saw for hidden or clad framing. |
Sizes, spans and the grade come from your truss design, the SANS 10400-L span tables or your engineer. Seal every cut end of treated timber, use galvanised fixings, and tie the roof down to the walls.
