Tensile Membrane & Structural Steel Materials Guide
Learn how architectural fabric membranes, polycarbonate sheets, and protective steel coatings perform in harsh Indian weather.
1. Architectural PVDF Coated PVC Membrane
Polyvinylidene Fluoride (PVDF) coated PVC is the most popular architectural tensile fabric in India. A high-tensile woven polyester base cloth is coated with PVC and finished with a top protective PVDF lacquer layer.
Weight range: 650 GSM to 1100 GSM
Light transmission: 8% – 18% translucent natural daylight
Expected lifespan: 10 to 15+ years
Features: UV resistant, self-cleaning surface, 100% waterproof, flame retardant.
2. PTFE Architectural Glass Mesh Membrane
Polytetrafluoroethylene (PTFE) coated woven fiberglass is the ultimate architectural membrane for major landmark structures, airports, and commercial plazas.
Expected lifespan: 25 to 35+ years
Fire rating: Class A / Non-combustible
Features: Immune to chemical corrosion and UV degradation, completely self-bleaching under solar exposure.
3. Polycarbonate Roofing Sheets
Available in multiwall or solid polycarbonate options, offering high impact strength (200x stronger than glass) while letting in natural daylight.
4. Structural Steel Frameworks
Structures are fabricated using heavy-gauge Mild Steel (MS) or Galvanized Iron (GI) hollow pipes, treated with epoxy primer and polyurethane (PU) architectural paint to prevent rust.
