Nicorex Alloys is an ISO 9001 and ISO 14001 certified, trusted metal sheets and plates supplier in Mumbai, stocking hot rolled plate and cold rolled sheets across nickel alloy, duplex, super duplex, and speciality steel families. Every batch ships with MTC 3.1 per EN 10204.
Sheet metal is a flat-rolled product made from slabs by hot rolling or cold rolling. From pressure vessel shells at 300-bar to 0.5 mm shim stock lining a pharmaceutical reactor, every metal sheet plate in a critical application must carry verified chemistry and documented origin. Flat products up to 6 mm (0.23 inch) thick are sheets; above 6 mm is a plate. Sheets are cold rolled for tighter tolerances. Plates are hot rolled for structural and pressure vessel work.
Our stock covers Hastelloy (C276, C22, C2000, X, Alloy 59), Inconel (600, 625, 625 LCF, 718), Incoloy (800/800H/800HT, 825), Monel 400, Nickel 200/201, Alloy 20, 904L, Duplex S31803/S32205, and Super Duplex S32750/S32760. Forms include HR plates, CR sheets, shim sheets, perforated sheets, chequered plates, coils, strips, and foils.
We supply plate and sheet metal from 0.5 mm and plates up to 200 mm thicknesses, in widths from 1000 to 2500 mm, and lengths from 2000 to 6000 mm or cut to your required size. Finishes include 2B, 2D, BA, No.1, No.4, No.8, hairline, and chequered. Cut-to-size sheet and plate services cover plasma, laser, waterjet, and shearing. We supply fabricators and EPC contractors across India and 40+ export markets.

Types and Forms of Sheets and Plates We Supply
Nicorex stocks multiple forms of sheets and plates for vessel fabrication, shimming, and coil-processing.
Shim Sheets
Thin metal sheets with a thickness of 0.05–2 mm are used to space and align rotating parts.
Perforated Sheets
Metal sheets with round, square, or long holes are used for filtering and airflow.
Chequered Plates
Plates with a raised pattern that prevent slipping on walkways and platforms.
Coils
Continuous flat metal is used for cutting, stamping, and roll-forming.
Strips
Narrow metal strips, 10–600 mm wide, are used for gaskets and stamping.
Foils
Ultra-thin sheets below 0.15 mm are used for heat shielding and laboratory use.
