6 mm Metal
crushed stone
6 mm crushed stone aggregate — the smallest coarse-fraction size we produce. Used where the placement is thin or where a smoother surface finish is required than 10 mm or 20 mm metal can deliver.
About 6 mm Metal
Conforms to IS 383:2016 for coarse aggregate of nominal size 6 mm. Produced from the Chimakurthy granite belt with consistent gradation and minimal silt or organic content, which improves packing and surface finish.
Where 6 mm Metal fits — and where it doesn't
Specifying the right aggregate size and grade saves cement, simplifies placement, and avoids rework. Below is a quick guide based on IS / MoRT&H norms and what we see ordered from our Chimakurthy crusher across Prakasam district.
Use 6 mm Metal for
- Thin concrete overlays (30 – 60 mm topping slabs)
- Decorative concrete finishes and exposed-aggregate work
- Micro-concrete and grout used for column / beam jacketing
- Precast elements with thin sections — copings, pavers, kerbs
- Concrete repair mortars and patching compounds
- Terrazzo and mosaic flooring
Don't use 6 mm Metal for
- Standard structural concrete (use 20 mm)
- Mass concrete or large pours (uneconomical fines content)
- Road base or sub-base (use Wet Mix or GSB)
