One of India's most complete sheet metal fabrication services, all under one roof in Ahmedabad: CNC laser cutting, press-brake bending, welding, rolling and powder-coat finishing, run by engineers, on time, to ±0.05 mm.
From a single laser-cut blank to a fully welded, powder-coated assembly, no subcontracting in between.
MS ≤ 20 mm, SS ≤ 12 mm, Al ≤ 10 mm, brass ≤ 6 mm on a TRUMPF TruLaser, ±0.05 mm.
Yawei PBA-110/3100, 1100 kN over 3100 mm. Repeatable, programmed bends.
TIG, MIG, spot and stud welding across MS, SS and aluminium by certified welders.
3-roll bender for cylinders and curves up to 20 mm thick, 2500 mm wide.
Radial drilling, bandsaw and lathe for finishing operations.
Powder coating (RAL), deburring, polishing and galvanizing partners.
Sub-assemblies and full enclosures, fixtured and inspected in-house.
5-tonne EOT crane for heavy plate and large weldments.
Most fabricators subcontract bending, welding or coating, and the buck gets passed when something slips. At Sigma, every operation happens on our own floor in Ahmedabad, so one team owns your part from drawing to dispatch, with daily WhatsApp photo updates.
18 years, 500+ delivered projects, and repeat orders from L&T, Inductotherm, Parle Global, Sacmi and Aqseptence back that promise.
