• Supplied Lengths: Standard 6.0-meter lengths; cut lengths and bundle quantities available upon request.

• End Finishes: Threaded (BSPT / NPT with heavy-duty end protectors) or plain/bevelled ends for mechanical grooved couplings and welding.

GI Malleable Iron Fittings — IS 1879 / BS EN 10242

Sourced from accredited foundries to ensure thread accuracy, pressure integrity, and full interchangeability with Class B and Class C lines.

• Available Fittings: 90° & 45° Elbows, Equal/Reducing Tees, Hex Nipples, Unions, Crosses, Bushes, Sockets, and End Plugs.

• Testing & Certification: Tested for working pressures up to 20 bar; Mill Test Certificates (MTC) supplied with consignments upon request.

• Coating: Hot-dip galvanized for seamless resistance against galvanic oxidation at the joints.

Square Hollow Sections (SHS) — Sourced to IS 4923 / ASTM A500

High-strength, cold-formed ERW structural square tubing procured from primary producers for commercial fabrication and architectural frameworks.

Site Handling & Application Advice

• Joint Integrity: Pair male threads with PTFE sealant tape or appropriate thread compound applied clockwise. Avoid excessive torque to preserve internal fitting threads.

• Galvanic Isolation: Always insert dielectric fittings or insulating flanges when connecting GI pipework to non-ferrous metals (such as copper or brass) to eliminate electrochemical corrosion.

• Hanger Intervals:

  • 15 mm – 25 mm NB: Support every 1.8 to 2.0 meters.

  • 32 mm – 50 mm NB: Support every 2.4 to 2.7 meters.

  • 65 mm NB and above: Support every 3.0 to 3.6 meters.

• Material Preservation: Keep pipe bundles elevated on level timber dunnage in covered, well-ventilated storage to protect fresh zinc surfaces against moisture traps and white rust.
