Tensile Structure Cost: What Drives the Price
There is no meaningful fixed rate per square foot for tensile work — two canopies of the same area can differ by a wide margin. This guide sets out the seven factors that actually move the number, and how to get a specific figure for your project.

How a tensile structure is priced
Tensile structures are priced individually, from the project’s own design — there is no meaningful fixed rate per square foot. Where a project’s cost lands comes down to a handful of factors, set out below.
Membrane
PVC-coated polyester is the base. A PVDF finish adds a little; PTFE-coated fibreglass can roughly double the fabric line. See the material comparison, what determines the fabric price, and how long each membrane lasts — a longer-life fabric can be the cheaper choice over the structure’s life.
Span and form
A simple single-slope cantilever is the cheapest form per square metre. A large clear span, a compound curved shape, or a set of many small separate structures each push the rate up.
Steel
Grade and section sizes, and whether the frame is hot-dip galvanised or painted. Coastal and industrial sites need heavier protection.
Foundations
Driven by the soil and the wind zone. Rock is cheap to found on; soft soil or a high-uplift wind zone needs bigger footings.
Site
Crane access, working height, and whether the site is occupied and has to stay operational during the build.
Scale
Large projects cost less per square foot than small ones, because the design effort and site mobilisation are spread over more area.
The rate should always be quoted itemised — design, steel, membrane, foundations and installation as separate lines — not as a lump sum. Send your area and site details for an exact figure.
The factors that move the number
Seven things decide where a project lands. Most of the total is steel and installation; the membrane is usually a minority.
Membrane grade
EffectPVC is the base; a PVDF finish adds a little; PTFE-coated fibreglass can roughly double the fabric line; ETFE cushions add an air system.
NoteSee the membrane comparison.
Span & form
EffectA simple single-slope cantilever is the cheapest form per square metre. A large clear span, a compound curved shape, or many small separate structures each push the rate up.
NoteSpan is often the single biggest driver.
Steel
EffectGrade, section sizes, and whether the frame is hot-dip galvanised or painted.
NoteCoastal and industrial sites need heavier corrosion protection.
Foundations
EffectDriven by the soil and the wind zone. Rock is cheap to found on; soft soil or a high-uplift wind zone needs bigger footings.
NoteUplift governs, not weight.
Structure height
EffectA taller structure catches more wind, so the frame and foundations grow.
NoteHeight is set from the use, not rounded up.
Site & access
EffectCrane access, working height, and whether the site is occupied and has to stay operational during the build.
NoteA live site adds sequencing cost.
Scale
EffectLarge projects cost less per square foot than small ones — the design effort and site mobilisation are spread over more area.
NoteA single carport is the most expensive per m².
How to get a specific figure
An indicative number is easy to give and usually wrong. A useful figure needs the site and the brief.
- Send a layout or a sketch — the area to cover, the rough dimensions, what is underneath, and any height or clearance needs.
- Tell us the site — the city, whether it is coastal or exposed, and whether it stays in use during the build.
- Tell us the brief — the design life and any fire class the occupancy needs, and whether a particular colour or form matters.
- We do a site survey — measured levels, access and soil information feed the design.
- You get an itemised quote — steel, membrane, foundations, installation and engineering as separate lines, against a design direction.
How it is engineered and built
The governing load
A tensile structure weighs almost nothing, so wind uplift is the governing load. The membrane is form-found into double curvature so it stays taut, and the frame and foundations are sized for the site’s design wind pressure under IS 875 Part 3.
Steel & foundations to code
The frame is designed to IS 800 and the footings to IS 456, checked for uplift and overturning. Galvanising to IS 4759 / IS 2629 for corrosion protection.
Built off-site, raised fast
Steel is cut, welded and galvanised in the workshop and the membrane is cut and welded into panels, while the footings are cast on site. On-site work is then quick and low-disruption.
One accountable team
Survey, 3D design, fabrication, installation and tensioning are all Ekra Decor’s own team, with a handover pack of drawings, load report, stability certificate and material certificates.

Tensile structure cost FAQ
The questions people ask about what a tensile structure costs.
There is no meaningful fixed rate per square foot. Cost is driven by the membrane grade, the span and form, the steel, the foundations, the structure height, the site conditions and the scale. Every project is priced individually after a site survey, with an itemised quote.
Because two canopies of the same area can differ by a wide margin — a tall clear span in PTFE on soft soil in a high wind zone versus a compact PVC cantilever on rock. A rate would be misleading.
Usually the span, followed by the structure height and the wind zone — all of which size the steel and the foundations. The membrane is normally a minority of the total.
Yes — PTFE-coated fibreglass can roughly double the fabric line, and it is slower to fabricate. A PVDF finish on PVC is a small uplift for a longer life.
Yes — the design effort and the site mobilisation are spread over more area, so the rate comes down with scale. A single carport is the most expensive per square metre.
Send a layout or sketch with rough dimensions, tell us the site and the brief, and we do a measured site survey. You then get an itemised quote against a design direction.
