Established in 2009 and incorporated as a Public Limited entity — DIPTI METAL INDUSTRIES LIMITED (CIN: U24104MH2026PLC476016) — our enterprise operates as a multi-certified global manufacturing powerhouse. Operating from our Corporate Head Office in Mumbai, India, we deliver high-integrity Ferrous & Non-Ferrous engineering solutions to a prestigious clientele in 65+ countries. Our specialization encompasses Carbon Steel, Alloy Steel, Stainless Steel, Duplex & Super Duplex Steel, Tool Steel, Nickel Alloys, Aluminum Alloys, Brass, Copper, and Titanium Alloys. We cater to mission-critical Oil & Gas (Petrochemicals), Chemical & Fertilizers, Marine, Offshore, and Power Generation sectors. In 2025-2026, we significantly expanded our footprint into Aerospace, Defence, and Metal Powders. To ensure world-class metallurgy, our raw materials are exclusively sourced from premium Non-China and Non-Russia mills.
Our technical work style for products beyond standard pipe fittings, flanges, and fasteners utilizes a highly successful, controlled Job-Work scenario. We manage an elite network of audited vendor facilities across Maharashtra, Gujarat, Punjab, Uttar Pradesh, Rajasthan, and Tamil Nadu. Furthermore, we maintain strategic Contract Manufacturing Agreements and NDAs with international manufacturers to ensure a seamless supply for global requirements. By directly supplying certified raw material ingots and billets and dictating all engineering drawings and Quality Assurance Plans (QAPs), we maintain 100% Heat Traceability and 100% PMI verification. This total oversight authorizes Dipti Metal Industries Limited to issue authentic Material Test Certificates (MTCs) per EN 10204 3.1 standards.
DIPTI® serves as a strategic fast-track alternative to primary mills. We specialize in the rolling of Round Bars, precision Wire Drawing, and custom rolling of structural Beams, Channels, and Angles. Our corporate facility management model allows us to minimize MOQ and drastically reduce lead times for global EPC contractors facing constraints at primary large-scale mills. We ensure project continuity through engineering integrity and rapid, certified delivery via major Indian ports.
*Materials exclusively sourced from Tier-1 Non-China & Non-Russia mills to ensure maximum compliance and safety for international defense and energy projects.
