Buying Guide

How to choose the right gi binding wire

GI binding wire is preferred over MS binding wire because the galvanized zinc coating prevents rusting and corrosion. This is especially important in Mumbai's humid and coastal climate where uncoated wire can rust within days.

For most construction work, 20 gauge is the standard choice. Use 18 gauge for heavy reinforcement (20mm bars and above) and 22 gauge for lighter slab work with thinner bars. The rule of thumb is: thicker the TMT bar, thicker the binding wire.

Buy in 25 kg bundles for the best rates. A typical residential project of 1000 sq ft requires approximately 15-20 kg of binding wire.
