Product Characteristics

• Material Composition:
  Manufactured from high-quality mild steel, coated with a layer of zinc (galvanization) for enhanced corrosion resistance.
• Types Available:
• • Light Gauge (Class A) – suitable for surface wiring and low mechanical stress applications.
  • Medium Gauge (Class B) – commonly used in commercial and residential installations.
  • Heavy Gauge (Class C) – ideal for industrial and outdoor environments requiring maximum protection.
  • Surface Finish:
  • Hot-dip galvanized or electro-galvanized for uniform zinc coating.
  • Available in pre-galvanized or post-galvanized variants depending on site requirements.
• Size Range:
  Standard diameters: 20mm, 25mm, 32mm, 40mm, and 50mm (as per BS EN 61386 standards).
  Standard lengths: 3.75  meters (custom lengths available on request).
• Threads & Accessories:
  Supplied with screwed ends and couplers or plain ends. Compatible with GI accessories such as bends, junction boxes, inspection tees, saddles, and locknuts.
• Compliance & Standards:     Conforms to BS 4568,

Recommendations and Restrictions

 Recommendations

• Ensure proper threading and tight coupling to maintain electrical continuity and mechanical strength.
• Use anti-corrosive paint or additional coating for installations in highly corrosive or marine environments.
• Employ appropriate saddles and clamps at regular intervals to prevent sagging or vibration.
• Always de-burr and smooth conduit ends before pulling cables to avoid insulation damage.
• Perform continuity and earthing checks after installation as per local electrical codes.
• Use inspection bends or tees to facilitate easy cable pulling in long or complex runs.

Restrictions

• Not recommended for direct burial underground unless specifically coated for such use.
• Avoid using in chemical plants or acidic atmospheres without additional corrosion protection.
• Not suitable for areas where high flexibility is required — in such cases, use flexible metallic conduits.
• Do not use if zinc coating is damaged or rusted — replace to ensure electrical safety.
