Key Features.
IBR 0.40 mm Galv Z150 Roof Sheet – 686 mm Cover, 3.6 m Length

- Profile: IBR (Inverted Box Rib) — a trapezoidal-rib profile with 686 mm net cover for efficient water drainage and structural strength.
- Material & Coating: Galvanized steel with Z150 coating — ensuring corrosion resistance and long-term durability against weather, rain and rust.
- Sheet Thickness: 0.40 mm — balancing lightweight handling and sufficient strength for typical roof loadings.
- Effective Coverage: 686 mm per sheet — reduces the number of sheets required and lowers installation time and overlap waste.
- Length (approximate): 3.6 m — convenient for mid-sized roofs, outbuildings, garages, carports and extensions where shorter sheets offer easier transport and handling.
- Lightweight & Easy Installation: Easier to carry and lay than heavier gauge or tile roofs — ideal for quicker builds or smaller labor teams.
- Versatile Use Cases: Suitable for roofing, side-wall cladding, carports, garages, agricultural buildings, warehouses or workshops — essentially any project needing reliable metal roof coverage.
Benefits.

- Durable & weather-resistant: The galvanized Z150 coating gives good corrosion protection in harsh weather, rain or damp climates — ensuring long roof lifespan.
- Cost-effective roofing solution: Compared to heavy roof tiles or thicker gauge metal, 0.40 mm IBR sheets reduce material, structural support and labor costs, while still providing solid roof protection.
- Quick installation & low maintenance: The ribbed IBR profile allows for faster installation and tight overlaps, reducing leak risk and ongoing maintenance needs.
- Flexibility for various projects: From small garages to large warehouses — suitable for many building types, making it a practical stock-item for builders and contractors.
- Lower structural load: Its light gauge means less load on roof trusses, allowing for simpler or lighter framing compared to heavier roofing materials.
Recommended Use & Installation Notes.

- Ensure correct purlin spacing and roof structure support — even lightweight sheets need adequate support especially under wind or hail conditions.
- Use compatible galvanized or stainless steel fasteners with rubber washers to prevent corrosion at fix points and ensure watertight sealing. (Standard roofing best practice for metal sheeting)
- Recommended minimum roof pitch: generally at least ~5° for proper drainage (as per IBR profile guidelines), especially on shorter roofs or where runoff is critical.
- For side-cladding applications, ensure correct orientation (broad-flute out if recommended) and proper fastening through flutes, not ribs — to reduce oil-canning and improve finish.
