Corporate Profile
Seamless Steel Industries (SSI) is a stocking distributor, indentor, and project supply partner based in Mumbai–Thane, Maharashtra, dedicated to specification-driven procurement and reliable commercial supply of seamless steel pipes, ERW pipes, alloy steel, stainless steel, buttweld fittings, and forged flanges.
Every procurement requisition is verified against precise engineering standards including ASTM, ASME, API, EN, DIN, JIS, and IS. We match project line items with primary and approved mill sources to ensure dimensional tolerances, metallurgical integrity, and exact schedule compliance.
Consignments are accompanied by Manufacturer Test Certificates (MTC) conforming to EN 10204 3.1. We facilitate third-party inspection (TPI) with accredited agencies including LRS, TUV, DNV, BV, SGS, and IRS to meet client and consultant quality requirements.
Our inventory coordination encompasses nominal bores from 1/2" NB to 24" NB and beyond, covering standard to extra-heavy wall schedules (Sch 20 through XXS). This enables single-source commercial fulfillment for complete piping packages.
Operating from the Mumbai–Thane industrial corridor provides immediate access to major national highway networks and Nhava Sheva (JNPT) container terminals, facilitating dependable dispatches across Maharashtra, Gujarat, Tamil Nadu, and pan-India project sites.
