Heavy Steel Fabrication
Precision Heavy Structural Steel Fabrication Services
At Kraficon Buildtek India, we specialize in high-capacity heavy steel fabrication engineered to support extreme mechanical stresses, heavy industrial crane operations, and large-span plant facilities. Utilizing advanced CNC plate cutting, submerged arc welding (SAW), and automated shot-blasting, we manufacture heavy structural steel members with micron-level tolerances.
From heavy-tonnage built-up I-girders and crane runways to multi-tier mezzanine frameworks and complex pipe racks, our facility executes custom steel manufacturing adhering strictly to IS 800, IS 2062 (Grade E250/E350 steel), and AWS welding codes. Every assembly undergoes non-destructive testing (NDT) to guarantee flawless load distribution.

High-Tensile Certified Steel Plates & Profiles (IS 2062 Grade E250 / E350)
-
Submerged Arc Welding (SAW) & Ultrasonic NDT Quality Inspections
-
Heavy Crane Gantry Girders & High-Tonnage EOT Support Brackets (Up to 50T+ Capacity)

Surface Treatment & Multi-Coat Anti-Corrosive Epoxy / PU Painting Systems
Controlled shop-floor manufacturing utilizing CNC oxy-fuel cutters and beam-drilling lines ensures 100% bolt-hole alignment during site erection.
Qualified AWS/IS welders execute full-penetration butt welds verified via Magnetic Particle (MPT) and Ultrasonic Testing (UT).
What grades of structural steel do you use for heavy fabrication?
We source prime, mill-tested steel plates and rolled sections conforming to IS 2062 Grade E250, E350 (BR/BO), and high-strength alloy plates depending on design stress requirements.
What quality checks are performed on fabricated steel assemblies?
Our quality assurance protocol includes raw material mill test certificates (MTC), dimensional verification, Ultrasonic Testing (UT) on full-penetration welds, Dye Penetrant Testing (DPT), and DFT paint thickness measurement.
Can you fabricate heavy gantry girders for EOT cranes?
Yes. We regularly manufacture heavy crane gantry girders, surge trusses, gantry rails, and stepped columns designed to handle dynamic impact loads for 5-Ton to 50+ Ton EOT cranes.
What surface protection treatments are applied to fabricated steelwork?
All fabricated members undergo Sa 2.5 automatic shot-blasting to remove rust and mill scale, followed by red-oxide zinc chromate primer, zinc-rich epoxy coating, or hot-dip galvanizing for harsh chemical/coastal environments.
Do you handle transport and high-reach crane erection on site?
Yes. We deploy heavy hydraulic mobile cranes, boom lifts, and certified rigging crews to execute safe, fast-track site erection under strict EHS safety compliance.
