Engineering Excellence & Custom Metallurgy
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 ProofInherent safety for volatile oil refineries, hydrogen plants, and offshore ATEX zones.
Extreme Bio-Fouling ResistanceCupro-nickel and copper surfaces inhibit marine organism growth in seawater intakes.
High Strength-to-Weight RatioStructural aluminum alloys reduce platform dead loads by up to 65% compared to steel.
Non-Magnetic & Thermally StableIdeal for sensitive electronics facilities, electrolysis cells, and cryogenic columns.
Material Selection
Non-Ferrous Alloy Portfolio Tailored to Your Specifications
Every industrial project requires strict compliance with metallurgy and environment. Review our primary non-ferrous manufacturing materials:
Aluminum Gratings
Fabricated using structural marine-grade aluminum alloys 6061-T6 and 6063-T6. Highly resistant to atmospheric corrosion, sulfur gases, and moisture while offering a lightweight profile that significantly decreases structural shipping and installation costs.
Alloy: 6061-T6, 6063-T6, 5052-H32
Finish: Mill, Anodized, or Powder Coated
Use: Water treatment, marine walkways, architectural sunshades
Copper & Brass Gratings
Produced from electrolytic grade copper and high-strength commercial or naval brass. Known for absolute non-sparking properties in explosive gas zones, exceptional electrical/thermal conductivity, and architectural anti-microbial longevity.
Engineered from 90/10 (C70600) and 70/30 (C71500) copper-nickel alloys. Delivers superior resistance to high-velocity seawater erosion, pitting corrosion, and marine microbial fouling in submerged or splashing offshore conditions.
Internal support plates for random packing, structured packing, and fractionation column trays requiring complete chemical inertness.
Desalination & Seawater Intakes
Cupro-nickel grating panels that prevent barnacle, algae, and molluscan adherence in cooling water ducts and intake canals.
Explosion Risk & Battery Rooms
Non-sparking copper and brass trench grates and platforms certified for petrochemical storage, hydrogen fuel stations, and munitions plants.
Offshore Platforms & Helidecks
Lightweight high-strength aluminum marine bar gratings engineered to endure salt-fog turbulence without structural fatigue.
Quality & Export Compliance
International Standards & Rigorous Quality Assurance
Manufactured to ASTM, BS, and DIN standards with 100% material traceability and strict dimensional verification prior to seaworthy packing.
Spectro & PMI Verification
Every non-ferrous raw material heat receives Positive Material Identification to verify precise elemental composition before fabrication begins.
Custom CNC Cutting & Banding
Panels are machined, notched, and fully banded with matching alloy perimeter bars to maintain full design load integrity and edge safety.
Surface Passivation & Polish
Chemical pickling, passivation, or electropolishing eliminates foreign surface impurities and enhances self-healing oxide barriers.
Heavy-Duty Seaworthy Crating
Packaged in fumigated solid timber cases with corrosion-inhibiting VCI foil layers for safe overseas container transport.
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.
