T Series PTFE Membrane
T-Series Membranes: Architectural Canopies & Tensile Roofs
The T-Series represents FIT's premier line of solid PTFE-coated fiberglass membranes specifically engineered for outdoor tensile structures, available in six weight grades from 1000g/sqm to 1600g/sqm. It is the ideal architectural solution for:
- Public Infrastructure: Transit stations, transportation hubs, and landscape canopies.
- Commercial & Civic Spaces: Outdoor pavilions, grand entrance canopies, and large-scale tensile membrane roofs.
Unlike open-mesh membranes or interior acoustic fabrics, the T-Series features a completely non-porous, solid-surface design. This ensures ultimate sun shading and 100% waterproof protection. Engineered to integrate seamlessly with structural steel frames, cable tensioning systems, and expert on-site rigging, the T-Series delivers an architectural canopy system that flawlessly balances striking aesthetics, reliable functionality, and extreme weather resistance.
The T-Series is a high-performance, solid PTFE-coated fiberglass architectural membrane engineered specifically for outdoor protective envelopes. It serves as the primary cladding and roofing material for tensile membrane structures, canopies, and grand entrance awnings.
Leveraging the material's inherent flexibility and advanced tensioning design, the T-Series enables massive clear spans, complex 3D curves, and streamlined silhouettes, eliminating the heavy, rigid constraints of traditional metal roofing and corrugated sheeting.
Designed for engineering projects that demand ultimate sun shading, 100% waterproofing, extreme weather resistance, lightweight efficiency, and architectural elegance, the T-Series is backed by FIT's comprehensive engineering capabilities. We provide fully integrated systems—including structural steel fabrication, specialized tensioning hardware, and precision perimeter clamping—to deliver structurally stable, visually iconic outdoor spaces.
Six weight grades are available from 1000g/sqm to 1600g/sqm, selected based on span and load requirements — see the "Specifications" tab for full technical data.
Solid, Non-Porous Design for Ultimate Protection
Engineered with a completely closed, non-porous surface, the T-Series is ideal for outdoor applications requiring dependable weatherproofing and full coverage. Compared to open-mesh fabrics, the T-Series provides maximum sun shading and 100% waterproof protection, making it the premier choice for permanent roofing, canopies, and long-term outdoor installations.
Engineered for Tensile Roofs & Large-Scale Canopies
The T-Series adapts seamlessly to advanced structural steel engineering, making it perfect for expansive clear-span canopies, complex curved roofs, and geometric custom tensile structures. Through precise tensioning and curvilinear modeling, it creates a lightweight, dynamic architectural envelope.
Fusing Weather Protection with Architectural Elegance
Beyond its primary protective functions, the T-Series leverages organic fabric contours, sleek supporting skeletons, and ambient light translucency to elevate the visual impact of any space. It is highly recommended for civic landmarks, transit hubs, and commercial entrances where premium brand image and aesthetics are paramount.
Built for Demanding, Long-Term Outdoor Exposure
Specifically formulated to withstand harsh environmental conditions, the T-Series is backed by FIT's rigorous engineering framework. We optimize long-term durability and ease of maintenance by integrating the membrane with heavy-duty anti-corrosion steel treatments, engineered connection nodes, and advanced drainage slope planning.
Turnkey Integration from Fabrication to On-Site Rigging
FIT delivers a single-source, vertical workflow encompassing material selection, structural analysis, steel fabrication, membrane processing, and expert on-site installation. By eliminating the typical coordination gaps between independent fabric and steel contractors, we streamline the construction process and ensure flawless project execution.
The T-Series is available in six weight grades from 1000g/sqm to 1600g/sqm, selected according to project load and span requirements. All grades are ISO 9001 certified with a 15-year warranty:
| Model | Yarn | Weight | Width | Thickness | Tensile Strength (Warp/Weft) | Fire Rating | Visible Light Transmission |
|---|---|---|---|---|---|---|---|
| T-1100 | EC 3μm | 1000 g/sqm | 380 cm | 0.60 mm | 6000/5500 N/5cm | Bs1d0 (GB8624) | 15% |
| T-1150 | EC 6μm | 1000 g/sqm | 380 cm | 0.60 mm | 6000/5500 N/5cm | B1/Class A (DIN/ASTM) | 13% |

How do I choose between the six T-Series weight grades?
Heavier isn't automatically better — selection depends on your span and load requirements. The lighter T-1100 and T-1150 (1000g/sqm) suit standard canopies and smaller spans. T-1300 and T-1350 are mid-weight grades with higher tensile strength for larger spans. T-1450 and T-1550 are heavy-duty grades, with tensile strength up to 10000/9000 N/5cm, suited to large-span or high-wind-load tensile roofs. We recommend having FIT's engineering team evaluate your specific site conditions.
What's the difference between the T-Series and M-Series facade mesh?
The difference is porosity. The T-Series has a solid, non-porous design for complete coverage — ideal for applications like transit stations and public infrastructure canopies that need full sun and rain protection. The M-Series is an open-mesh design that allows light and airflow through, more commonly used on building facades. Both are PTFE-coated fiberglass membranes; the difference lies in the weave structure and application.
Is the T-Series suitable for long-term outdoor exposure?
Yes. The T-Series is engineered for long-term outdoor use, with fire ratings including DIN 4102-1 B1 and ASTM E84/E108 Class A, backed by a 15-year warranty. It can be paired with anti-corrosion steel treatments, engineered connection nodes, and drainage slope planning to maintain long-term weather resistance.
Does the T-Series membrane need to be installed with a steel structure?
Yes. As a flexible material, the T-Series requires a structural steel frame and tensioning system to form a stable canopy or roof. FIT provides a single-source workflow — material selection, structural analysis, steel fabrication, membrane processing, and on-site installation — all handled by the same team.
