High-Performance Non-Ferrous Alloys Engineered for Demanding Environments

Omkar Gratings Pvt Ltd manufactures high-precision non-ferrous metal gratings custom fabricated from specialized non-iron alloys including structural aluminum, pure electrolytic copper, naval brass, and cupro-nickel. Developed primarily for harsh marine exposures, distillation towers, and explosion-sensitive industrial operations, our non-ferrous products deliver unmatched corrosion prevention, non-sparking safety, and thermal properties.

Unlike standard carbon or galvanized gratings, non-ferrous open mesh solutions provide specialized physical characteristics required inside critical process equipment—serving as internal catalyst bed supports, vapor-liquid contact grids, filtration column floors, and demister retainers where chemical compatibility is paramount.

Non-Sparking & Explosion Proof Inherent safety for volatile oil refineries, hydrogen plants, and offshore ATEX zones.
Extreme Bio-Fouling Resistance Cupro-nickel and copper surfaces inhibit marine organism growth in seawater intakes.
High Strength-to-Weight Ratio Structural aluminum alloys reduce platform dead loads by up to 65% compared to steel.
Non-Magnetic & Thermally Stable Ideal for sensitive electronics facilities, electrolysis cells, and cryogenic columns.
Industrial non-ferrous gratings fabricated to engineering drawings

Technical FAQ

Frequently Asked Questions by EPC Engineers & Buyers

What non-ferrous metals and alloys can Omkar Gratings fabricate?

We fabricate custom non-ferrous gratings from structural and architectural aluminum (6061-T6, 6063-T6, 5052-H32), electrolytic grade copper (C11000), commercial and naval brass (C26000, C46400), cupro-nickel alloys (Cu-Ni 90/10 and 70/30), and phosphor bronze. All panels are built strictly to customer layout drawings and project load requirements.

Why are non-ferrous gratings selected over carbon or stainless steel?

Non-ferrous gratings are specified when steel or stainless steel cannot meet particular physical demands. Aluminum provides over 60% weight reduction and corrosion resistance without painting; copper and brass offer verified non-sparking safety in explosive atmospheres; and cupro-nickel alloys provide unmatched natural bio-fouling immunity and resistance to high-velocity seawater erosion in marine and offshore vessels.

How are non-ferrous gratings used in distillation and process filtration columns?

Inside refining, chemical, and alcohol distillation columns, non-ferrous gratings serve as structural support grids for random packings (such as Raschig rings or saddles), structured packing beds, and catalyst retainers. The alloys prevent unwanted chemical reaction with process vapors, endure thermal cycling, and maximize open free area for liquid and gas flow.

What technical documentation is provided with export shipments?

All export consignments include complete EN 10204 Type 3.1 Mill Test Certificates (MTC), Positive Material Identification (PMI) spectrometer test reports, dimensional inspection certificates, welding procedure specifications (WPS/PQR), and heat-treated export packing certificates.

Can circular, segmented, and cut-out configurations be supplied?

Yes. A substantial portion of our non-ferrous manufacturing involves vessel internal discs, annular rings, multi-segment pie pieces, and cut-outs for vertical pipe clearance. All segmented panels are stamped with individual piece-mark tags that correlate with assembly layout plans.
