Six claims every tensile fabricator makes — here's what backs ours, specifically.
Tailor-made structural analysis using ixCube and ANSYS to withstand localized wind loads up to 150 km/h.
Every membrane is form-found and patterned in software before a single panel is cut — not estimated on-site.
We use 100% genuine Serge Ferrari, Mehler, and Heytex membranes with verifiable test certificates.
The same fabric grades installed at DLF Cybercity, JN Stadium, and Delhi Gymkhana Club — see the project gallery.
Industrial HF seam welding creates molecularly fused fabric joints that never pull apart under tension.
Unlike sewn or glued seams — the first failure point on cheaper structures — an HF-welded seam is often stronger than the base fabric itself.
Comprehensive written structural and fabric warranty covering tear resistance, seam integrity, and colour stability.
Backed by original material certificates from our European suppliers — documented, not just promised.
Mobile installation squads equipped with crane rigs, tensioning winches, and safety rigging gear.
Delhi to Bengaluru to Goa — one accountable contractor for design, engineering, fabrication, and installation, no subcontractor hand-offs.
Specialized PVDF top-coat finish sheds dust and grime automatically during routine rainfall.
Rated to hold that self-cleaning performance for 15+ years without recoating.
On an architectural membrane the open fabric field is rarely where problems begin — the seam is. How the panels are joined is what keeps a roof watertight for its full 15 to 30-year design life, or lets it start wicking, peeling, and leaking within a few. It is worth confirming before you sign a contract — our walkthrough of how a tensile structure is built covers where the seam sits in the wider fabrication sequence, and our ten questions to ask before you sign set out what a quotation should answer first.
Welding parameters — temperature, pressure, and dwell time — are set per membrane batch and logged. PVDF top-coats are abraded back in the weld zone and edge-sealed, since the finish is not weldable as supplied.
One accountable contractor from the first site visit to the final tensioning — design, engineering, fabrication, and installation all run in-house, with no subcontractor hand-offs.
We start with a site survey to record dimensions, ground conditions, clearances, and the look you are after. From that we carry out form-finding — generating the exact anticlastic, conical, or hyperbolic-paraboloid geometry in which the membrane stresses stay balanced. You receive 3D visuals, general-arrangement drawings, and an itemised quotation.
Our engineers run the wind, rain, and (where relevant) snow and seismic loads to the applicable IS codes. What comes back to you is a membrane stress report and the foundation reactions your civil contractor builds to — issued as drawings and figures, before anything is cut.
The curved surface is unrolled into 2D cutting patterns with pre-stress compensation, then plotter-cut and HF-welded into panels in our Delhi workshop. Panels are welded rather than stitched or bonded, because the seam — not the open fabric field — is what decides how long the roof stays watertight; our walkthrough of how a tensile structure is built shows where it sits in the sequence. In parallel, the steelwork is CNC-profiled, welded to WPS, shot-blasted to Sa 2½, and given a zinc-rich primer and polyurethane top-coat (or hot-dip galvanised). Cables are cut to length with swaged end fittings and load-tested.
Foundations are cast to the calculated uplift and overturning loads using anchor-bolt templates. Steel is erected, plumbed, and torqued; the folded membrane is hoisted, spread, connected at every edge and corner, then tensioned in a staged sequence until the design prestress is reached and the surface is wrinkle-free. We check every seam, weld, bolt torque, and tension reading, confirm the surface drains with no ponding, and hand over as-built drawings, mill certificates, a structural stability certificate, and an O&M manual — backed by a one-year written warranty on the structure, a 5 to 15 year membrane warranty by fabric grade, and an optional annual maintenance contract.
We source top-tier architectural membranes certified for extreme weather resistance and fire safety — graded by strength, weight and service life, from entry-level PVC through to PTFE fibreglass.
High-tenacity polyester base fabric coated with premium PVC — the most versatile, cost-effective membrane for complex, curved architectural forms.
High-grade Polyvinylidene Fluoride coating offers self-cleaning properties and exceptional UV protection.
Polytetrafluoroethylene coated glass fabric engineered for monumental spans and extreme lifespan requirements.
Ultra-lightweight, 95% translucent pneumatic foil ideal for botanical domes, atriums, and skylights.
What does "N/5cm" mean? It's the standard tensile-test unit for architectural fabrics — the breaking force (in Newtons) of a 5cm-wide strip, tested separately along the warp and weft yarn directions. A higher number means the membrane can safely span greater distances under wind and snow load.
Fire ratings are quoted in the standard each membrane is certified to: DIN 4102 for PVC and PVDF, EN 13501-1 for PTFE and ETFE.
Fabrication on site, an ETFE cushion roof, a retractable membrane and a finished auditorium — four short clips.

Ekra Decor Pvt. Ltd. is a turnkey tensile structure manufacturing firm based in Delhi NCR. We combine advanced 3D CAD membrane modeling, high-frequency German welding technology, and precision steelwork fabrication to deliver precision-fabricated tensile architecture.
Our engineered membrane solutions protect commercial spaces, corporate campuses, luxury residences, and public infrastructure against severe weather, wind, and UV degradation. Completed projects include the arrival-passenger walkway canopy at IGI Airport Terminal 2, the entrance canopy at ILBS Hospital, Vasant Kunj, and the escalator-court canopy at Vasant Square Mall.
Our factory and head office sit at Rangpuri on NH-8, which puts most of Delhi NCR — Gurugram, Noida, Greater Noida, Faridabad and Ghaziabad — within a short drive for site surveys and installation crews. Beyond NCR we work from a Bangalore regional office and have delivered in 36+ cities, including Hyderabad (Tata Steel Services), Mumbai (Siemens), Kolkata (Vikram Solar), Bangalore (BDA housing), Srinagar (Hazratbal Dargah), Lucknow and Indore. The Bangalore office also handles enquiries from Chennai and Kerala. If you are still specifying, our guides cover what actually drives tensile fabric price, how long a tensile structure lasts, and the Serge Ferrari membranes we fabricate with.
Every project runs through an ISO 9001:2015 certified quality process and is backed by a 5 to 15 year membrane warranty by fabric grade, with original material certificates from our European suppliers. Structures are engineered and tested to withstand wind speeds of 150 km/h, so what we hand over is built to outlast the delivery date, not just meet it.
Our quality management system for the design, engineering, fabrication, and installation of tensile fabric structures and architectural membranes is independently certified to ISO 9001:2015. Company registrations for GST, Udyam (MSME), and Import-Export Code are also on record.
Design, engineering, and execution — the people who take every tensile structure from drawing board to finished site.

Everything you need to know about our premium tensile fabric structures.
Design life depends on the membrane specified. PVC-coated polyester typically lasts 10–15 years, PVDF-coated polyester 15–20, ETFE film 25 or more, and PTFE-coated fibreglass 30 or more. Properly galvanised or painted steelwork outlives the fabric, so most structures are re-skinned rather than replaced. Correct tensioning and welded seams matter as much as the material grade — see our full guide to tensile structure lifespan.
Every structure is engineered to the wind zone of its actual site under IS 875 (Part 3), not to a generic figure. Our standard design basis is a 150 km/h wind speed, with steel section sizes, foundation reactions and membrane prestress calculated per project. Coastal, high-altitude and cyclone-prone sites are designed to their own higher category.
Yes. Ekra Decor runs the whole scope in-house: site survey, structural and form-finding design, 3D membrane modelling, steel fabrication, membrane cutting and high-frequency welding, foundations, erection and final tensioning, using our own installation crews. One accountable contractor with no subcontractor hand-offs, delivered to sites in 36+ cities across India.
A membrane warranty of 5 to 15 years depending on the fabric grade, covering the fabric’s tear resistance, seam integrity and colour stability, and a one-year written warranty on the structure and workmanship, alongside the structural steelwork. It is backed by original mill certificates from our European membrane suppliers, so the specification you were quoted is the specification you can verify on site. An optional annual maintenance contract is available.
There is no single rate. Cost per square foot is set by the membrane grade (PVC, PVDF, PTFE or ETFE), the clear span and column layout, the steel tonnage and its finish, the height and foundation conditions, and site access. A car parking shade and a large-span PTFE roof sit at opposite ends of that range. We issue a free itemised quote after a site survey — see what actually drives tensile fabric price.
Most standard car parking and walkway tensile structures are fabricated in 10 to 15 working days and installed on-site within 3 to 7 days. Large-span auditorium or stadium membrane roofs may take 3 to 6 weeks end-to-end. All steelwork is pre-fabricated at our Delhi facility to minimise on-site disruption.
PVDF and PTFE membranes are largely self-cleaning and need only periodic rinsing with water and a visual inspection of tension cables and anchor points once or twice a year. Ekra Decor offers optional Annual Maintenance Contracts (AMC) covering re-tensioning, cleaning, and structural health checks across India.
Yes. Every Ekra Decor tensile structure is fully bespoke. Our engineers model conical, hyperbolic-paraboloid (hypar), barrel-vault, dome, and free-form membranes in 3D CAD to match your exact plot dimensions, load requirements, and architectural intent, from a single-car gazebo to a 50,000 sq ft arena roof.
Yes. Delhi NCR is our home market. Our factory and head office are at Rangpuri on NH-8, so Gurugram, Noida, Greater Noida, Faridabad and Ghaziabad are all served directly from it, usually with a site survey within a few days of the enquiry. We also run projects from our Bangalore office and have delivered in 36+ cities nationwide.
