Ours is that the Aim customer does not face any kind of problem by our side. We are the Ekra Decor Tensile Structure. Our company believes that it is our responsibility to properly satisfy the customer.

The Process OF Tensile Fabric Structure

The characteristics of a tensile fabric structure are very different than traditional building
components. Flexible and lightweight materials are placed in tension, or combination of
tension and compression, to create shapes and designs not possible with traditional materials.
The freedom of form is really only confined by imagination and site conditions; and is why
tensile architecture is so embraced and utilized for large span roof systems, amphitheaters,
and shade structures to provide texture and a unique eye catching element..
Complex curvilinear shapes are more affordable and achievable with fabric, which can be cost
prohibitive to do with rigid materials. And, with an extremely high resistance to weather and
environmental stress and ability to meet building code requirements, tensile fabric structures
can last as long or longer.
The Signature Team designs structures to meet the clients’ vision while incorporating the underlining requirements of the project. Working with an
experienced company will streamline the entire design, fabrication and installation process, ensuring that the project is kept within the project
budget. Our services include building from existing structure systems to designing new systems from ground up. The use of a flexible PVC
membrane, cables and custom steel components allow for an endless array of shapes and forms available for a project. The drawings below
are examples of tensile systems we have designed.

When designing a tensile fabric structure, materials, the site location and size all play important roles in the final cost. The cost consists of
materials, design & engineering and final construction of the structure. The materials are typically comprised of three key elements—steel,
fabric and cables. Labor and the site location are also important factors which can affect the cost and should be incorporated at the design
The first step in designing a tensile fabric structure is a site visit or detailed review of
photographs where the structure will be located. Per the site location and client requirements,
we design the optimal roof form which suits the aesthetics and engineering requirement, while
keeping in mind the client’s budget. In the case of a reskin or roof replacement, we evaluate the
structural elements to define what can be recycled and what needs to be replaced, as well as
location and set up for a 3D survey. When working with existing structure components, a 3D survey

The membrane can be folded in a variety of methods
determined by the construction methodology to accommodate the easiest and most economical installation.
Upon completion, roof panels are packaged in special PE bags, a complete bill of materials is developed and
the components are prepared for loading and shipping.

Performance Of Tensile Fabric Structures


A frequently asked question is if tensile are suitable for windy sites. The answer is yes as long as the canopy is properly engineered. In the computer analysis of the different load cases wind uplift is usually as great as the live snow load. A factor of safety between 4 and 6 is then used to select the fabric weight.

The detailing of the fittings and surrounding structure needs to take into account the maximum deflections of the membrane. Boundary details need to accommodate the oscillations that may be generated at the canopy extremities. Our conical canopy in Mauritius is 32m in diameter and is designed for and had regularly experienced 150 mph winds.

In these extreme circumstances an annual re-tension/maintenance check is recommended. Designing for heavy snow loads requires more care as you have greater risk of melt water ponding. The profiles would generally need to be steeper and spans smaller.Image result for Autocad drawing tensile structure


PVC fabrics incorporate UV stabilisers which protect colour fastness and base cloth slowing the rate of degradation, however in high UV lifespan will be reduced. After 20 years the PVC will lose its flexibility and will become more brittle. In areas of high humidity regular cleaning will reduce the risk of mould growth on the surface of the fabric causing permanent staining. For design life over 10 years in areas of high UV, pollution or humidity, PTFE/glass becomes a better option.


The fire performance of a membrane depends on the basecloth and the seam details. All membranes will de-tension under high temperatures. The speed will start peeling apart at around 100. At 250c the PVC membrane will melt back from the heat source creating vent holes for heat and smoke.

PVC has fire retardants in the coating so that if self extinguishes when the flame source is removed and therefore would not produce flaming droplets. With PTFE fabric the glass base cloth withstands temperatures up to 1000c and the openings are limited to failed seams which would part at approx 270c.

The net effect in a fire can be quite beneficial as most canopy designs form a smoke reservoir which may well allow sufficient time for escape, and when sufficiently hot self venting will occur through a failed seam. Critical steelwork should be supported so that partial failure of a damaged roof will not cause collapse of the structure.

The design should consider smoke generated by the membrane used. PTFE fabric used internally may require sprinkler systems or mechanical extraction to reduce toxic fume production at temperatures over 400c.


As you would expect in some cold weather conditions condensation is likely to occur with roofs covering a sealed heated space. The design of the roof gradients and edge detailing can minimise any problems.

Ventilation can obviously reduce the risk but if more control is required then it would be necessary to incorporate a second skin and possibly additional thermal quilt. Control of the air flow in the air gap is recommended to get the best environmental control. A sealed gap is best in winter for insulation and good air flow in the summer will help cooling. The design of roofs especially conic forms can make use of the passive stack effect ventilation with fans or louvres used to enhance the performance if requiredRelated image


A single fabric membrane is virtually transparent to low frequency sound due to its low mass. A double skin with an acoustic quilt inter layer will give you the absorption figures required. Reverberation times on the other hand can be very successfully reduced with tensile fabric linings with acoustic quilt behind wither wall mounted or hung on drop wires.


Unlike glass or brittle panels fabric is highly resistant to impact damage from blunt objects. It is however susceptible to sharp objects.

Small cuts can be repaired with glue-on patches. Larger tears may need specialist repair with portable hot air welders. If an invisible repair is required then the membrane may need to be removed and a replacement panel inserted in the factory. Graffiti solvents may damage the PVC lacquers so should be avoided.

PTFE fabrics are highly resistant to abuse as paints wont key to the surface. The sensible solution is to design out the problem as much as possible but putting the fabric out of reach and details the masts accordingly to minimise the risk of climbing. In vulnerable areas a modular canopy with slide out panels may be a sensible precaution to minimise replacement costs. Some structures such as public bus stops in very exposed sites are probably not ideally suited for membranes.

Advantages over overhead glass canopies are that thrown objects tend to bounce off a fabric canopy and health and safety issue of falling glass is largely resolved.


For the smaller structures this is done with long handled brushes and soapy water if necessary from cherry pickers or tower scaffolds. With the larger membranes trained rope access riggers abseil from high level anchorage points or traverse across the membrane with a Latchway or similar restraint system using brushes and water filled back packs or pressure washers.

Every structure has its own maintenance manual describing fixing points and cleaning procedures. Ideally canopies should be cleaned annually but PTFE/glass fabric would be the preferred option if cleaning is unlikely or impractical. This is because its inherent no-stick surface resists pollutant adhesion and allows rain to clean off most dirt. Raw PVC is readily adhered to by pollutants so all membranes are treated with dirt resistant lacquers or surface foils.

Careful cleaning maintains their life and the optimum appearance of the membrane.


The fabric manufacturer can issue a 5 year up to a 10 year warranty covering the structural strength and integrity of the fabric. The specialist subcontractor can be asked for a collateral design warranty. We recommend that structures have annual inspections to ensure the ongoing integrity of each critical component.
