Engineering That Moves Industry Forward

STECOO Steeltech Engineering & Construction Operations LLP delivers pressure vessels, storage tanks, process piping and structural steel across a range of steel grades, including stainless steel. From single, one-off fabrications to larger, complex and bespoke projects, requirements are planned and manufactured at our dedicated workshop area near the Visakhapatnam Special Economic Zone (VSEZ) / Auto Nagar in Visakhapatnam.
Every project is manufactured to order, engineered around the customer's exact specification rather than off a generic catalogue. Fabricated items are carried through a structured series of quality checkpoints referenced against API, AWWA, ASME and CE standards before shipment, and the team is experienced in surge vessels, spool-piping and architectural steel structures to ASME-referenced practice.
Steeltech is experienced in the design of steel tanks and firefighting tanks, and in specialised hydraulic lifting and plate-tilting devices. The engineering group designs, fabricates and supplies EGW, SAW, BWM and C&B welding machines to client-specific requirements for customers in the UAE, Saudi Arabia and Turkey, supported by design teams in Turkey and India. The company also supplies manpower for projects in Turkey, Saudi Arabia, the UAE and within India.
Built on Engineering Discipline
Engineering-Led
Technical engineering and fabrication expertise applied from first survey through final drawing, not just shop-floor assembly.
Made to Order
Every pressure vessel, tank, pipe spool and structural assembly is engineered to the customer's stated requirement — no generic off-the-shelf substitutes.
Fabrication + Installation
Support spans engineering and CAD drawings through fabrication and, where scoped, on-site installation — managed to minimise disruption at the customer's site.
International Experience
STECOO's leadership and engineering team bring engineering and site-management experience from tank, piping and mechanical projects across GCC markets, carried into the LLP's own working methods.
Structured Quality Focus
Production is checked through defined quality checkpoints, with standards referenced against API, AWWA, ASME and CE practice and supported by qualified inspection personnel.

A Dedicated Fabrication Facility Near VSEZ, Visakhapatnam
STECOO's facility sits near the Visakhapatnam Special Economic Zone (VSEZ) / Auto Nagar industrial belt, close to Duvvada Railway Station — a location chosen to serve both local and export-bound fabrication work efficiently.
The site combines a covered fabrication shop with a larger open fabrication yard, equipped with oxy-acetylene cutting machines, welding equipment and the fabrication tools and tackle needed to take a project from raw plate to finished, inspected assembly.
Work is managed from order intake through site survey, engineering calculations and CAD drawings, into material control and fabrication, quality control, and — where scoped — installation at the customer's site, with the aim of minimising disruption during that final stage.
