Structural Steel Fabrication
SISPL is a structural steel fabrication company running design, cutting, welding, finishing and erection from a single in-house plant in Chakan, Pune — so the drawing that engineers your frame is the same one that builds it.
— About the Fabricator
Most structural steel fabrication contractors hand off at least one stage of the job — cutting to one vendor, painting to another, erection to a labour contractor nobody on the design team has met. SISPL doesn't run that way.
Every primary and secondary steel member that leaves our Chakan plant is cut, welded, roll-formed, blasted and painted inside our own facility by a 120-plus-strong technical team accountable for the whole order, not just one station on the line. That's what lets us operate as both a structural steel manufacturer and an erection contractor, hand a fabrication drawing straight to the shop floor that built it, and field a site query in Marathi, Hindi or English without anything getting lost between design intent and execution.
The result, after more than 170 delivered projects: a steel fabrication contractor that industrial clients keep calling back for the next building, not just the first one.

General FAQs
A structural steel fabrication company turns a structural design into physical steel members — cutting plate and sections, welding built-up columns and rafters, punching connection holes, and finishing the steel with blasting and painting — so the frame can be erected on site exactly as the drawing specifies.
PEB manufacturing is a specific, optimised branch of structural steel fabrication. Conventional fabrication often uses standard hot-rolled sections, while PEB fabrication builds tapered, built-up sections sized to the bending moment along their length — which usually reduces steel tonnage and cost for clear-span industrial buildings. Both rely on the same cutting, welding and finishing capability.
Indian projects are typically designed to IS 800:2007 for general steel structures, IS 875 (Parts 1-5) for dead, live and wind loads, IS 1893 for earthquake-resistant design, and IS 456 for associated concrete elements. Projects following international specifications also reference AISI, AWS D1.1, and ASCE 7 / IBC.
Yes. Design and detailing, fabrication, finishing, transport and on-site erection run as one scope, so a single contractor is accountable for the structure from the first cutting drawing to the last bolted connection.
The Chakan plant runs CNC plasma cutting beds up to 24 × 4.2 metres, a 16 mm-capacity hydraulic shearing line, and dedicated PTW H-beam welding lines for built-up primary members, with present output of roughly 20,000 metric tonnes a year, scaling toward 2,00,000 metric tonnes annually as new capacity comes online.
The manufacturing unit is in Chakan, Pune, Maharashtra, with a corporate office in Pimpri. An in-house transport fleet and crane support move fabricated structural steel to industrial sites across Maharashtra and to project locations across India.
