The Foundation of Industrial Infrastructure

Heavy structural fabrication forms the backbone of industrial infrastructure — from power plants and refineries to bridges and high-rise buildings. It involves the cutting, shaping, welding, and assembly of steel components that must withstand immense loads and extreme conditions.

Advanced Machinery & Capabilities

Modern structural fabrication relies on state-of-the-art equipment. CNC plasma cutting machines deliver precision profiles up to 50mm thickness. Heavy plate rollers (up to 3000 ton capacity) form curved sections. Robotic welding systems ensure consistent weld quality, while hydraulic presses handle complex forming operations. Shot blasting and painting lines provide superior surface preparation and corrosion protection.

Materials & Specifications

Structural steel grades like IS 2062 E250-E410, ASTM A36, and high-strength quenched and tempered steels are commonly used. Each batch is tested for chemical composition, tensile strength, yield strength, and impact toughness. Material traceability is maintained throughout the fabrication process.

Quality Control in Fabrication

A rigorous QC plan covers every stage: incoming material inspection, fit-up checks, welding procedure qualification (WPS/PQR), welder performance qualification, dimensional inspections, and final assembly verification. NDT methods including UT, MPI, and RT are applied to critical welds. Surface preparation and painting are inspected against SSPC and NACE standards.

Project Management & Execution

Successful structural fabrication projects require meticulous planning. Experienced project managers coordinate design approvals, material procurement, shop fabrication, surface treatment, transportation, and site erection. Advanced project management tools ensure timelines are met without compromising quality or safety.
