Quality Assurance

Documented inspection at every stage — from raw-material receipt through fabrication, welding and galvanizing to final dispatch — backed by an in-house testing laboratory and open to third-party inspection.

Quality Control at Every Stage

Our quality management system is ISO 9001:2015 certified. Every order is subject to documented inspection protocols from raw-material receipt to final dispatch.

Raw-Material Inspection

Incoming steel verified against Mill Test Certificates. Chemical and mechanical properties checked for compliance with IS 2062 and customer specifications.

Dimensional Inspection

All cut, drilled and fabricated components checked against GA drawings. Tolerances per IS 7215 or customer specs. Jig checks for critical assemblies — jigs and fixtures are built in our own tool room.

Weld Quality Control

Visual weld inspection per IS 822. Welder qualifications maintained per WPS / PQR. NDT (dye-penetrant, ultrasonic) conducted as required.

Galvanizing Inspection

Coating thickness measured with calibrated DFT gauges. Adherence test. Visual check for bare spots, lumps and drips. Results recorded in a galvanizing report.

Third-Party Inspection

Inspections by BVQI, SGS, Bureau Veritas, DNV, TÜV and customer-nominated agencies are fully supported; records are maintained to facilitate them.

Pre-Dispatch Inspection

Final check before loading. Assembly trial for complex structures. Marking, stencilling and bundling per export or client packing requirements.

Our Testing Laboratory

A dedicated in-house lab enables complete mechanical, chemical and galvanizing certification — reducing turnaround time and reinforcing quality at every stage. Our German-built Bruker spectrometer reads steel, zinc, aluminium and copper, so both the incoming steel and the zinc in our kettle are verified under our own roof.

7-Stage Galvanizing Pre-Treatment

Coating quality is decided before the steel ever touches zinc. Every consignment passes this sequence in our 7-metre kettle line.

1
Degreasing

Alkaline degreasing removes oils, grease and organic contaminants.

2
Water Rinse

Rinsing removes chemical residue after degreasing.

3
Acid Pickling

Hydrochloric-acid bath removes mill scale and rust, exposing clean steel.

4
Water Rinse

Removes acid and residual scale.

5
Fluxing

Zinc-ammonium-chloride flux prevents oxidation and aids bonding.

6
Drying

Warm-air drying eliminates residual moisture before immersion.

7
Hot-Dip Galvanizing

Immersion in molten zinc at 450 °C forms a durable multi-layer coating.

8
Quenching & Cooling

Water quench or air cool; thickness measured with DFT gauge per IS 2629.
