Tensioned membrane structure
PVC coated polyester tensile membrane fabric for architectural structures — stadium roofs, canopies, skylights, facades, and pedestrian bridges. Industry grades I–V (800–1,550 gsm); higher grades = heavier base fabric = higher load capacity + longer lifespan. PVDF topcoat is standard for outdoor durability (15–20 year, self-cleaning).
Technical Specifications
| Grade | Weight gsm | Tensile N/5cm (warp/weft) | Tear N | Light % | Lifespan |
| I | 800 | 3,000/3,000 | 350/310 | — | 10–15 yr |
| II | 900 | 4,400/3,900 | 580/520 | ~8 | 15–18 yr (PVDF) |
| III | 1,050 | 5,750/5,100 | 800/950 | 8–12 | 15–18 yr |
| IV | 1,300 | 7,450/6,400 | 1,400/1,100 | 8–12 | 15–20 yr |
| V | 1,450 | 9,800/8,300 | 1,800/1,600 | 8–12 | 18–20+ yr |
Glass-Fiber Base Option (35+ Year Lifespan)
| Base | Weight | Tensile N/5cm | Lifespan |
|---|---|---|---|
| Glass-fiber Grade II | 800 gsm | 3,500/3,500 | 35+ yr |
| Glass-fiber Grade III | 1,150 gsm | 5,800/5,800 | 35+ yr |
| Glass-fiber Grade IV | 1,550 gsm | 7,500/6,500 | 35+ yr |
Market Compliance & Import Considerations
| Region | Key standard |
| Europe | EN 13501-1 B-s2,d0 (fire, closed/public); DIN 4102 B1 (Germany common); HS 5903.10.90 ≈ 8% |
| USA | NFPA 701 + ASTM E84 FSI≤25 (Class A); CAN/ULC-S109; HS 5903.10.15 = DUTY FREE |
Typical Applications
- Stadium & sports hall roofs (Grade IV–V)
- Commercial corridors & pedestrian bridges (Grade II most popular)
- Canopies at retail, hotels, airports
- Facade cladding (natural daylighting)
- Landscape shade sails & sculptural installations
How to Select the Right Specification
| Light-load temporary | Grade I – 800 gsm |
|---|---|
| Commercial corridor (most common) | Grade II – 900 gsm / PVDF / Anti-wick |
| Medium-span transit hub | Grade III – 1,050 gsm |
| Large-span stadium / facade | Grade IV – 1,300 gsm / Grade V – 1,450 gsm |
| 35+ year landmark | Glass-fiber base (≈ 2× price, 35+ yr) |
| Public building fire | EN 13501-1 B-s2,d0 — FR mixed into PVC compound (not surface-coated), ask for accredited lab reports |
Procurement Checklist
- Specify: tensile + tear + peel requirements, fire rating per local code, surface finish (PVDF/acrylic/matte), print ink compatibility
- All values are industry-typical ranges — we provide third-party lab test reports with every batch
- Import tariffs & anti-dumping change frequently — verify the latest WTO schedule before pricing
- Contact [email protected] with your spec requirements and target market for a quick quotation
Quality Assurance and Customization
Every Tensioned membrane structure is produced under ISO 9001-controlled processes and tested to ASTM D751 for tensile, tear, and adhesion performance. Typical properties include a basis weight around 800–1500 g/m² g/m² and a PVC-coated polyester, PTFE-coated glass fiber, or ETFE construction selected for stable welding and long service life. KeZHiBo offers custom widths, colors, and surface treatments—anti-fungal, anti-static, or FR-rated—with third-party inspection available on request, supporting both OEM volumes and project-specific specifications from prototype to delivery.
