Fabricated Steel Structures Manufacturers in India

Fabricated steel structures are built by cutting, shaping and welding steel sections and plate into frames, buildings, tanks, pressure vessels, platforms and equipment supports. Quality depends on the welding procedure, the qualifications of the welders, inspection and the standard the design follows.

How to choose

State the design code or standard and the loads, since a structure, a storage tank and a pressure vessel are governed by different rules.
Check the fabricator’s procedures: welding procedures, welder qualifications and how they are recorded.
Ask about inspection and testing: visual checks, dye penetrant, magnetic particle, ultrasonic or radiographic tests, and hydraulic tests for vessels.
Confirm the material grades used and the certificates for plate and sections, and how they are traced through the job.
Look at the surface treatment: blasting, primer and paint systems or galvanising, and the thickness checks for coatings.
Check the shop’s capacity: the size and weight it can handle, lifting, machining and the ability to trial-assemble large work.
Ask about drawings, change control and documentation at hand-over, and the experience with similar projects.

Frequently asked questions

What is a welding procedure and why does it matter?

A welding procedure is a documented method that has been tested to show it produces sound welds in a given material and thickness. Qualified procedures and welders give consistent, reliable welds.

How are welds inspected?

By visual inspection first, then by tests such as dye penetrant, magnetic particle, ultrasonic or radiographic examination depending on the code and the criticality of the weld.

What is the difference between painting and galvanising?

Paint systems protect steel with layered coatings and can be repaired on site. Hot-dip galvanising coats the steel in zinc for long-life protection with little maintenance, but the part size is limited by the bath.

What should I provide for a quote?

Design drawings, the code or specification, the materials, the quantity and weight, the coating and the inspection and documentation you require.

What documents should I receive at hand-over?

As-built drawings, material and weld test records, inspection reports, coating records and any certificates your standard requires. Agree the list before fabrication starts.

Can I contact the manufacturers listed here directly?

Yes. Each listing shows the contact details the company has published, with no lead form or middleman. Confirm procedures, inspection and capacity with the company before ordering.
