About Roofing Bolt

Roofing bolts have a wide, low mushroom head with a square neck, so they sit flush on sheet metal and do not turn while the nut is tightened.

Builders and sheet metal fabricators across Thanjavur district use them to fix roofing sheets to purlins on sheds, godowns and farm buildings. Choose GI for long outdoor life.

Common applications

  • Roofing sheets and purlins
  • Sheds, godowns and cattle sheds
  • Sheet metal fabrication
