Project Overview
from Ekra Decor’s
project records
Ekra Decor built a tensile structure for a client in Mumbai recorded in the archive as “Seamen Caloa” — a name that could not be independently identified and may be a transcription of a different company name, so this page describes the structure rather than the client.
At about 3,260 m², and classified in the archive as an industrial project, the structure is the scale of a covered storage or working yard, a staging or laydown area, or a weather-protected process or loading zone. Mumbai has one of the heaviest urban monsoons in the country, so a genuine weatherproof roof over a working area is a substantial gain there.
The archive records about 3,260 m² and a roughly three-month build.
Project Highlights

Substantial industrial canopy
About 3,260 m² — a covered yard, staging area or working-zone scale.
Built for the Mumbai monsoon
The membrane geometry and drainage are sized for sustained, heavy urban rainfall.
Around a three-month build
A programme in proportion to the footprint.
Column-light span
Wide bays keep forklift and vehicle movement free underneath.
Client name unidentified
“Seamen Caloa” could not be confirmed and may be a garbled transcription.
Corrosion-aware build
A hot-dip-galvanised frame for the humid coastal air.

The Brief
A weatherproof roof over a working area
An industrial site in Mumbai has a clear seasonal problem: for months the monsoon is heavy enough that any uncovered working or storage area is effectively out of use. The brief for a canopy is a proper weatherproof roof over that area, sized for Mumbai rain, built without stopping the site.
Ekra Decor delivered the structure as a turnkey job: survey and setting-out, 3D structural and membrane design, fabrication of the galvanised steel frame and the welded fabric, and installation and tensioning, over about 3,260 m² in roughly three months. The archive does not record which area the canopy covers, so this page keeps that general.
Design & Engineering
An industrial roof sized for heavy rain
The canopy is designed around the working area it covers — columns to the edges and out of the vehicle and material paths, membrane spanning the area overhead, clear height set for the equipment underneath.
The fabric is form-found in 3D and pre-stressed into double curvature so it stays taut under wind uplift. What gets particular attention on a Mumbai site is the drainage: the fall, the valley and eaves details and the outlet sizing are designed for sustained heavy rainfall, so water clears fast and does not pond and add load. Ekra Decor designs the steelwork to IS 800 and checks the structure for wind, rain and seismic loading to the applicable Indian codes, with the foundations sized against uplift and the steel hot-dip galvanised against the humid coastal air.
Fabrication & Installation
Prefabricated, erected around operations
The steel is cut, welded and hot-dip galvanised in the workshop and the membrane is cut and high-frequency welded into panels off-site, so on-site work is limited to casting the foundations, erecting the frames and tensioning the membrane.
On a working site the sequence is fenced and planned around activity, with completed areas handed back as they are finished. The canopy went up in about three months.
The Result
A working area that stays usable in the rains
The site gained a substantial covered area that keeps working through the Mumbai monsoon — stock, equipment or operations under a real roof rather than out in the rain. Upkeep is limited to cleaning and periodic checks.
Ekra Decor builds industrial canopies and covered yards for manufacturing and logistics clients. See more finished work on the projects page, or read about tensile structures in Mumbai.

Common Questions
About this project & building something similar
Where is this project located?
Mumbai, Maharashtra.
How large is the covered area?
3,260 m², per Ekra Decor's project records.
How long did this project take to build?
≈3 months from start to finish, per Ekra Decor's project records — in line with the standard 10 to 15 day fabrication and 3 to 7 day on-site installation timeline used across most projects.
Who was this project built for?
“Seamen Caloa” (name likely garbled, not independently identified).
Are there real photographs of this project?
Yes — 6 photographs from Ekra Decor's own project archive appear in the gallery above, not a stock or illustrative image.
Can Ekra Decor build something similar for my site?
Yes — every project starts with a site survey and a custom 3D design tailored to your space, not a fixed template. Get in touch to discuss a similar structure for your own site.
What membrane material would a structure like this be built in?
The choice depends on span, climate and intended lifespan. PVC-coated polyester is the most cost-effective option, with a 10–15 year service life. PVDF-coated polyester adds a self-cleaning top layer and pushes that to 15–20 years. PTFE-coated fibreglass is a permanent, non-combustible membrane with a life measured in decades, and ETFE film is used where an ultra-light, highly transparent roof is needed.
Is the structure engineered to Indian standards?
Yes. Wind, rain and — where relevant — snow and seismic loads are analysed to the applicable IS codes, and the steelwork is designed to IS 800. The membrane is form-found so its stresses stay balanced in double curvature, and the foundations are sized against uplift and overturning rather than gravity alone — the governing case for a lightweight tensile roof.
What warranty and documentation come with the structure?
Up to a 10-year written warranty on the membrane, plus as-built drawings, original mill certificates for the membrane and steel, a structural stability certificate and an operation & maintenance manual on handover. An annual maintenance contract covering inspection and re-tensioning is optional.
How much maintenance does a tensile structure need?
Very little — a periodic wash to remove surface dirt, and an annual check of cable tension and bolt torque. PVDF and PTFE membranes are largely self-cleaning, so rain keeps them looking new. We can carry this out under an annual maintenance contract if you prefer.
