FABRICATION

Steel Fabrication Services in India — A Manufacturer, Not a Fabrication Company That Outsources

Every process below runs inside our own works. Many fabrication companies quote the job and then place it elsewhere; we do not subcontract, so dimensional responsibility and the delivery date sit with one company. Our steel fabrication services and metal fabrication services in India cover structural, heavy, stainless, sheet metal and custom work.

No subcontracting

One works, one drawing, one team accountable for the dimension and the date.

Structural steel fabricators in India

As structural steel fabricators serving customers across India, we fabricate beams, columns, trusses, purlins, bracings, gantries and portal frames for industrial sheds, warehouses, plant structures and pre-engineered buildings. Members are cut, drilled, welded and match-marked in the works, then cleaned and primed so your erection crew can bolt up on arrival rather than rework on site. Because we also manufacture the anchor bolt package, the holding-down assembly and the frame it receives are made to the same drawing by the same team — which is where most base-plate misalignment problems start.

Match-marked, cleaned, primed

Stainless steel fabrication in India

We carry out stainless steel fabrication in SS304 and SS316 for customers across India in food processing, water and effluent treatment, pharmaceutical and coastal installations. Stainless work is handled with segregated tooling and consumables to avoid carbon contamination and the surface rusting that follows it, and is finished by pickling and passivation where the application calls for it.

Sheet metal fabrication in India

We supply sheet metal fabrication to equipment builders and OEMs across India — enclosures, panels, guards, ducting, hoppers, brackets and one-off assemblies. We work from your drawings, a physical sample or a 3D model, in mild steel, galvanised sheet, stainless and aluminium.

Heavy and custom metal fabrication services

Heavy plate and section work to 40 mm cutting thickness on a 50-tonne lifting capacity, for power, cement, mining, oil and gas and water treatment plants. Custom metal fabrication covers everything that does not fit a catalogue: non-standard profiles, oversized assemblies and single-piece replacements for obsolete equipment.

HOW WE WORK

From Your Drawing to a Certified Delivery

01

Drawing review

Send a PDF, DWG or DXF with the grade, finish and quantity. We check it against manufacturability before quoting — bend radii, thread engagement, projection lengths and galvanising allowances are where drawings most often need a query raised, and it is cheaper to raise it now than after production.

02

Quotation and committed date

You receive a price and a delivery date together. Lead time depends on quantity, grade and finish — hot-dip galvanised items take longer than plain or zinc plated — so the date is confirmed on drawing approval rather than promised in advance. There is no minimum order quantity.

03

Manufacture

Cutting, forming, machining, welding and threading run in-house across a 150 MT per month capacity. Nothing is held in stock; every item is made to your specification.

04

Inspection and documentation

Dimensional inspection before dispatch, with Mill Test Certificates on every batch. Third-party inspection to your nomination and coating thickness verification for galvanised work are arranged on request.

05

Dispatch

We deliver and service across every state in India — not only dispatch. Material moves by road or rail to site, our team supports installation and fitment queries wherever it lands, and export consignments ship through Chennai Port with sea-worthy packing and full documentation.

FAQs

Frequently Asked Questions — Foundation Bolts, Fabrication, Capacity & Delivery

Common questions about our foundation bolts, anchor bolts, steel fabrication services, production capacity, minimum order quantity, materials, documentation and delivery from E S HAJI & CO

Do you provide stainless steel fabrication?

Yes. We carry out stainless steel fabrication in SS304 and SS316 as a service, not only stainless fasteners. Stainless work uses segregated tooling and consumables to prevent carbon contamination, with pickling and passivation where the application requires it.

Are you structural steel fabricators as well as bolt manufacturers?

Yes. We fabricate beams, columns, trusses, purlins, bracings and portal frames alongside the anchor bolt package that fixes them. Having both made to the same drawing by the same works removes the base-plate alignment issues that arise when the bolts and the frame come from different suppliers.

Do you supply foundation bolts outside Tamil Nadu?

Yes. We are foundation bolts suppliers to the whole of India, dispatching by road and rail to Mumbai, Pune, Bangalore, Hyderabad, Coimbatore, Delhi NCR, Ahmedabad, Kolkata and Visakhapatnam, and exporting through Chennai Port.

What is your monthly production capacity for foundation bolts and fabrication?

Our Chennai works produces up to 150 metric tonnes per month across foundation bolts, anchor bolts and fabricated steel assemblies, supplying customers across India and for export.

Is there a minimum order quantity for foundation bolts?

No. There is no minimum order quantity. We manufacture single trial batches and multi-tonne project consignments alike, always to the customer's drawing.

Is E S HAJI & CO ISO 9001:2015 certified?

Yes. E S HAJI & CO is ISO 9001:2015 certified ensuring strict quality control, inspection procedures and reliable manufacturing standards.

What materials and grades do you use for foundation bolts and fabrication?

We use carbon steel, mild steel, stainless steel (SS304, SS316), duplex steel and alloy steel with optional galvanized or electroplated finishes.

A manufacturer. We are not a trading house or a reseller — every bolt and every fabricated assembly is produced in our own 18,000 sq.ft. works in Ambattur, Chennai, on our own machines, by our own team. We have manufactured on this site since 1924.

What industries does E S HAJI & CO serve?

Industries include Oil & Gas, Power, Thermal, Water Treatment, Mining, Food Processing and Construction.

How do I get a quote for foundation bolts or steel fabrication?
