Excellence in Engineering
Tensile structures in Kolkata, engineered to be trusted for decades.
Ekra Decor brings in-house engineering and fabrication to Kolkata's unique blend of heritage architecture and modern commercial development. Our structures are engineered for Kolkata's high humidity and heavy monsoon conditions, using corrosion-resistant materials and robust structural design.
From residential societies in Salt Lake and New Town to commercial developments in Park Street and Rajarhat, our tensile structures enhance outdoor spaces across the City of Joy. We specialize in creating structures that complement Kolkata's rich architectural heritage while delivering modern functionality.
-
/01 Custom 3D Form-Finding
Every canopy is form-found and load-tested in ixCube and ANSYS before fabrication begins — engineered off-site, never estimated on-site.
-
/02 Genuine PTFE & PVDF Membranes
We install only certified, traceable fabrics — the same grades used across our online project gallery. No generic substitutes.
-
/03 Turnkey, Single-Team Delivery
Site survey, steel fabrication, and installation handled by one accountable in-house team — no subcontractor hand-offs at any stage.

Weather-Resistant Tensile Structures in Kolkata
Kolkata experiences heavy monsoons, high humidity, and occasional cyclonic winds. To address these extreme weather conditions, Ekra Decor engineers heavy-duty tensile structures with reinforced steel framing and high-tensile waterproof membranes.
From covered walkways in Salt Lake Sector V to large-span stadium roofs and industrial sheds across West Bengal, our structures are built to endure. We prioritize structural stability and superior water drainage systems, ensuring our Kolkata installations provide safe, reliable shelter during the toughest weather.
Common Questions
Frequently Asked Questions
Find out everything you need to know about our premium tensile structures.
Yes — two documented projects, including a large-scale installation for Vikram Solar, each linked above with its own case study.
No — Ekra Decor runs from a single Delhi NCR base and delivers to Kolkata from there. The same in-house design and installation team handles every site nationwide, Kolkata included.
Yes — heavy monsoon rainfall, high humidity and occasional cyclonic winds call for reinforced steel framing and high-tensile, waterproof membranes with strong drainage detailing, more so than in a drier inland city.
The same indicative range applies nationally: ₹250–650 per sq ft, depending on membrane, span and steelwork. See the full cost guide for what drives the number; site conditions and access in Kolkata are factored into the itemized quote after a survey.
Fabrication typically takes 10 to 15 working days at our Delhi facility; on-site installation in Kolkata then adds roughly 3 to 7 days, depending on site access.
