Tensile Structure in Valsad

Valsad district, with Vapi, Sarigam, Umbergaon and the GIDC estates along the south Gujarat coast, is one of India's most concentrated chemical, pharmaceutical, dyes and engineering manufacturing belts — and the district is also known for its horticulture (Valsad's Alphonso and Kesar mangoes, chikoo) and agri-processing. The tensile demand is industrial: large covered spans over plant and process areas, warehouse and loading cover, and covered yards.

Ekra Decor's documented Valsad project is about 28,492 sq ft of continuous single-span tensile membrane roof on a steel frame, supplied for Plasser through the Valsad-based contractor Desai Construction Pvt. Ltd.

Valsad is on the Mumbai–Ahmedabad corridor, a long haul from the Delhi NCR base. Steel and membrane are fabricated at the workshop and shipped; the same in-house team installs. For the full technical background, see the tensile structure guide.

On the coast the steel specification matters as much as the fabric: hot-dip galvanising plus paint or duplex coating, and stainless cables and fittings where exposed. Full comparison on the membrane materials page.

• Site survey & soil investigation — coastal and alluvial soils vary, so foundations are sized from the site's own soil investigation to IS 456.
• Wind — wind uplift is taken to the coastal, cyclone-fringe design figure under IS 875 Part 3.
• Drainage — steep falls, oversized valley and eaves gutters and a designed overflow route for the heavy south-Gujarat monsoon.
• Coastal corrosion package — galvanising plus paint or duplex coating on the steel, stainless cables and fittings where exposed.
• Long single spans — a continuous single-span roof like the Desai Construction project needs the primary steel and the membrane both sized for the span, with movement joints and drainage planned across the whole length.
• Working through a main contractor — Ekra Decor works either directly or, as at Valsad, as the tensile-roofing specialist to a main contractor, integrating with their steel and programme.
• Corrosion protection — the steel is hot-dip galvanised; the coating class is set by the local air.
• Thermal movement — the seasonal temperature swing is designed into the connections so the membrane never slackens.
• Off-site fabrication — steel and membrane are cut and made at the workshop and shipped, so the on-site work is assembly and tensioning.
