🪨 Product Guide

What Is GSB?

GSB (Granular Sub-Base) is well-graded granular material that forms the foundation layer of a road, below the WMM base course.

GSB (Granular Sub-Base) is well-graded granular material — crushed granite and gravel blended across a range of sizes — that forms the lowest structural layer of a road, spreading load and helping drainage.

At Mrs Bluemetals our GSB is produced at our VSI plant in Keerapakkam and graded to MORTH Section 400 — the Ministry of Road Transport & Highways specification — from our BIS-certified plant. Every load is weigh-bridge checked before dispatch. See the MORTH specifications.

Buying factory-direct keeps the gsb price in Chennai low: ₹950 per tonne, all-inclusive and delivered, with test reports included free. Resellers add a margin and bill transport separately.
