Structural steel framing and mezzanine deck fabricated and erected by LKS Industries

Structural fabrication & erection

An in-house fabricator, not a trader

Pre-engineered buildings, industrial sheds, structural steel frames, pipe racks, mezzanine floors, platforms and site infrastructure — designed, fabricated in-house and erected at site across Tamil Nadu and South India.

Why this division exists

The same shop floor, the same welders, the same site crew

LKS Industries manufactures industrial valves, strainers, storage tanks, pressure vessels, heat exchangers, pipe spools and skids from its own facility in Chennai. That same shop floor, welding capability and site crew support our structural division.

So the steel that frames your plant and the equipment that runs inside it come from one accountable vendor. One purchase order, one set of drawings to approve, one number to call when the programme moves.

  • We quote on your GA drawing or work from a site visit.
  • Fabrication drawings are issued for your approval before steel is cut.
  • Members arrive shop-primed and match-marked for a bolted site fit-up.
  • Painted and inspected before sheeting, so no coating work is left at height.

Working with us

From drawing to erected steel

We quote on your GA drawing or work from a site visit, and prepare fabrication drawings for approval before cutting steel.

Enquiry & site data

Drawings, spans, heights, loads and site constraints reviewed.

Quotation

Rate per MT or lump sum, with scope, finish and exclusions written out.

Fabrication drawings

Shop drawings issued for your approval before material is cut.

Shop fabrication

Cutting, fit-up, welding and painting under in-house supervision.

Delivery & erection

Transport, site erection, alignment and handover with records.

Before you send an enquiry

What we need to quote accurately

Send these six things and you will get a firm rate rather than a range with caveats attached.

  • GA drawing or sketch — bay spacing, span and eave height.
  • Crane / hoist details, if the structure is to carry one.
  • Roof and wall sheeting specification, or confirmation that sheeting is by others.
  • Floor loading for mezzanines and platforms, in kg/m².
  • Paint system required — primer only, epoxy, PU or galvanised.
  • Site location, access and target erection window.

Also manufactured in-house

The structural division sits alongside our equipment manufacturing, so a single order can cover both.

ValvesGate, globe, ball, butterfly, knife gate, check / NRV, foot, slide gate and diaphragm valves.
StrainersY-strainers ½″ to 60″, basket strainers simplex and duplex, T-strainers and conical strainers.
EquipmentStorage tanks, pressure vessels, heat exchangers, pipe spools and skids — TPI available for pressure equipment.
MaterialsCarbon steel, SS 304, SS 316, SS 316L, cast iron and ductile iron.

Third-party inspection can be arranged for pressure equipment. Structural fabrication is carried out to IS dimensional standards and to approved client drawings.
