Self-Supported Roofing Solutions for Industrial & Commercial Projects
Sairaj Roofing designs, fabricates, supplies, and installs self-supported and trussless roofing systems for industrial and commercial projects across Pune, Maharashtra, and India.
Roofing Expertise Built Around Engineering
With over a decade of industrial execution, Sairaj Roofing delivers turnkey self-supported arch roofing systems backed by structural calculation, on-site precision fabrication, and professional installation.
Design & Structural Analysis
Engineered to withstand regional wind pressures (IS 875) with optimized arch rise-to-span ratios for maximum volumetric utility.
On-Site Continuous Fabrication
Mobile roll-forming machinery deployed at the site produces unbroken arch panels matching the entire building span.
Motorized Mechanical Seaming
Panels are locked together using motorized seaming equipment to create a continuous double-fold weather envelope with zero piercing screws.
What Is Self-Supported Roofing?
Self-supported roofing is an arch-shaped structural system formed from cold-rolled corrugated Galvalume steel panels that span between support beams without requiring intermediate trusses, purlins, or columns.
The specially formed corrugations provide structural rigidity, allowing the roof to serve simultaneously as the primary load-bearing arch and the weather-tight roof membrane.
- Clear-Span Interiors: 100% unobstructed internal headroom for high racking and cranes.
- Zero Bird Perches: Eliminates roosting points and bird contamination over goods.
- Leak-Resistant: Double mechanical seam folds without piercing sheet fasteners.
- Rapid Construction: Formed directly on-site for faster project delivery.
