- Raw Material Procurement — We source only from reputable mills with traceable heats and valid MTCs (EN 10204 / 3.1).
- Incoming Inspection — Every incoming lot is checked for dimensional accuracy, surface condition, and PMI verification before being accepted into stock.
- In-Process Controls — Dimensional checks, weld seam inspection, and visual audits at each stage of processing (cutting, beveling, threading, packaging).
- Final Inspection & Testing — Products undergo hydrostatic, ultrasonic, eddy current, and visual inspection as per applicable standards before dispatch.
- Documentation Package — Each order ships with Mill Test Certificates, inspection reports, packing lists, COO (Certificate of Origin), and any additional third-party inspection reports (Bureau Veritas, TÜV, Lloyd’s Register, SGS, Intertek).

Metinox Overseas supplies Stainless Steel Pipes & Tubes (grades 304, 304L, 316, 316L, 316Ti, 317, 321, 347, 904L, Alloy 20, SMO 254), Duplex & Super Duplex Pipes (UNS S31803, S32205, S32750), Carbon Steel Pipes (API 5L, ASTM A106), Alloy Steel Pipes, Nickel Alloy Tubes, and Large Diameter Pipes. Both seamless and welded types are available across all schedules.
Metinox Overseas operates as both a manufacturer-linked supplier and an established stockist. We source directly from reputed global mills and maintain a large ready stock inventory, enabling us to fulfil both standard and custom orders with short lead times.
Yes. We are experienced in GCC import compliance and can assist with SABER product registration, MODON approvals, and other Saudi Arabia-specific regulatory requirements to ensure smooth customs clearance and project compliance.
SS 316L pipes are preferred in pharmaceuticals (WFI and clean steam lines), food & beverage (dairy and beverage transfer), chemical processing (acid and alkali lines), marine environments, and desalination plants. The low carbon content (0.03% max) and molybdenum addition (2–3%) provide superior corrosion resistance — particularly against chloride stress corrosion cracking — and allow post-weld service without sensitisation.
