Engineered and Installed by Westcoast Roofing Systems Ghana
The future of roofing is not just about what covers the top of a building — it is also about the structure beneath. At Westcoast Roofing Systems Ghana, our G550 and AZ150 lightweight steel trusses deliver a new standard of strength, safety, and long-term value for residential, commercial, industrial, and estate projects.
Lightweight truss technology replaces the heavy, termite-prone, warp-susceptible timber systems of the past with engineered steel members designed for precision, durability, and faster installation.
What is G550 Steel?
G550 is high-tensile structural steel with a minimum yield strength of 550 MPa, meaning it can withstand high loading conditions without bending, sagging, or collapsing.
Key Properties of G550 Steel:
- Ultra-high strength (550 MPa grade)
- Lightweight but stronger than timber
- Uniform manufactured dimensions — no warping, twisting, or shrinking
- 100% termite, borer, and fungus proof
- Non-combustible — will not fuel fire
- 100% recyclable and environmentally responsible
What is AZ150 Coating?
AZ150 refers to a 150 g/m² aluminium-zinc alloy coating applied to the steel to provide superior corrosion resistance, especially important for Ghana’s coastal and humid environments.
Why AZ150 Matters:
- 3x better corrosion resistance than galvanised steel
- Ideal for beachfront, lagoon, and marine-exposed projects
- Protects against rust, salt air, and acidic rain
- Extends structural life cycle beyond 40+ years
- Lower maintenance = reduced lifetime cost
Why Lightweight Trusses Outperform Timber
| Feature | Timber | G550 / AZ150 Steel Trusses |
|---|---|---|
| Weight | Heavy | Lightweight, easier to handle |
| Durability | Rot, termites, burning | Fire-safe, pest-proof, rust-protected |
| Accuracy | Warps and cracks | 100% dimensionally stable |
| Installation | Slow and labour-intensive | Faster, prefabricated, engineered |
| Maintenance | Requires treatment | Almost maintenance-free |
| Lifespan | 8–15 years average | 40+ years with correct installation |
