Roofing & Steel Structure Solutions for Modern Construction
Building Durable and Efficient Roofing Systems with China’s Proven Manufacturers
In large-scale construction, the roofing and steel structure systems play a critical role in ensuring a building's durability, weather resistance, and structural efficiency. Whether you're constructing a logistics warehouse, an industrial park, or a community shelter, choosing the right materials — from roofing sheets to purlins and waterproofing — determines your project’s performance and lifecycle cost.
At BuildLink China, we provide end-to-end sourcing, evaluation, and advisory services for the full range of roofing and steel structural components. With deep expertise in China’s supply chain and technical standards, we help you select high-performance, cost-efficient, and field-proven materials directly from Tier-1 factories.
Color Steel Roofing Sheets
Corrugated color steel roofing sheets are widely used in industrial warehouses, commercial sheds, agricultural buildings, and prefabricated homes. Manufactured from galvanized steel or galvalume (AZ), these sheets offer excellent corrosion resistance, aesthetic appeal, and fast installation.
- Lightweight and easy to install
- High corrosion resistance (with proper paint coating)
- Cost-effective over large areas
- Customizable in length and wave profile
A 10,000 sqm food warehouse project in Kenya required rapid installation with 0.5mm AZ150 color roofing sheets. Thanks to our factory's stock program, delivery was completed within 7 days, helping the client meet a tight construction schedule.
C/Z Purlins (Cold-formed Galvanized Steel Sections)
C-shaped and Z-shaped purlins serve as essential secondary structural components in metal building systems. They support roofing and wall panels, acting as the main frame between steel columns and roofing sheets.
- Supports large-span steel roofing
- Reduces structural weight compared to H-beams
- Fast assembly with bolt connection
- Lower material cost with reliable load-bearing capacity
- Thickness: 1.5mm to 3.0mm
- Widths: 80mm to 300mm
- Galvanized coating: Z275 to Z350
A 4,000 sqm agricultural greenhouse in Uganda used pre-punched Z140 purlins with roof slope matching to local wind load conditions.
Waterproof Membranes (Bitumen & PVC)
To extend the lifespan of your roof system, a high-performance waterproofing layer is essential — especially for flat roofs, lightweight steel structures, and prefabricated buildings.
We recommend either bitumen-based self-adhesive membranes or PVC/TPO waterproofing rolls, depending on your climate, slope, and construction type.
Bitumen Membranes:
- Ideal for industrial warehouses, basement structures
- SBS or APP modified bitumen
- Easy torch-on application
- High tensile strength, puncture resistance
PVC/TPO Membranes:
- Heat-welded installation, fully recyclable
- Resistant to UV, root penetration, chemicals
- Longer service life (15–30 years)
A government school dormitory roof in Ghana used 1.2mm TPO membrane with mechanical fasteners, saving 18% on maintenance costs over 10 years.
