Tensile membrane structure

Shade sail canopies

A shade sail is a tensioned sheet of fabric stretched between posts or building fixings.

Built around the site

A shade sail is a tensioned sheet of fabric stretched between posts or building fixings. It gives quick, flexible cover for patios, play areas, cafes and car parks, with angled and twisted forms that shed water and look lighter than a flat roof.

WhiteShed Solutions LLP designs shade sails in triangular, rectangular and hypar shapes, with steel posts and tensioning hardware sized to the span and wind exposure. Where more permanent, weatherproof cover is needed, the same approach scales up to full tensile membrane structures.

Typical applications

  • Cafes, restaurants and outdoor seating
  • Schools, play areas and sports courts
  • Residential patios, gardens and building entrances
  • Parking bays and loading areas
  • Resorts and hospitality outdoor spaces

    Why choose a shade sail canopy?

    Shade at modest weight

    A light fabric roof on slim posts.

    Shapes that shed water

    A twist or slope in the sail directs rain off the fabric.

    Flexible layouts

    Several sails can overlap to cover irregular areas.

    Colour choice

    Fabric colours can match the surroundings or brand.

    Quicker to fit than solid roofs

    Fewer elements to erect on site.

    From concept to completion

    01

    Site visit and measurement

    We measure the area and check where the frame can be anchored.

    02

    Design and engineering

    Drawings, structural checks and the material layout are prepared for approval.

    03

    Fabrication

    The frame and components are made to the approved drawings.

    04

    Installation

    Our team installs the structure and completes the finishing and drainage details.

    05

    Inspection and handover

    The structure is inspected and handed over after completion.

    Frequently asked questions

    A shade sail is a lighter tensioned fabric canopy on posts. A tensile structure is engineered for larger spans, heavier loads and permanent weather cover. We recommend one or the other after seeing the site.

    It depends on the fabric. Waterproof membrane fabric sheds rain, while open-weave shade cloth gives shade but not rain cover. We specify the fabric to your need.

    Yes, if the wall or beam can take the pull from the sail. We check the fixing points on site.

    Typically ₹350 to ₹700 per sq ft before GST, depending on fabric, size and structure load. The final figure follows your site details.

    It depends on the number of sails, the area and site access. The schedule is confirmed in the proposal.

    Specifications at a glance

    Fabric

    Engineered composite membrane: typically high-tenacity polyester or fibreglass mesh coated with a protective polymer

    Posts and fixings

    Mild steel posts with a protective coating, or fixings to an existing wall or beam

    Tensioning

    Cable edges and turnbuckles for a tight, wrinkle-free sail

    Shapes

    Triangle, rectangle and hypar

    Span

    Engineered to the project requirement and confirmed by the structural design for each site

    Warranty

    Up to 15+ years, depending on the structure requirement and fabric GSM

    Installation time

    Depends on the structure, area and site access; confirmed in the proposal

    Wind and structural design. Wind uplift is usually the critical load on a membrane structure. Each structure is checked for prestress, dead, live, wind and thermal loads, and for ponding, as part of its structural design.
