The Economics of Specific Gravity

Why Green Diamond
Goes Further

Green Diamond has a lower specific gravity than copper slag and garnet. That means one 50 lb bag contains more abrasive volume — delivering more blasting power and coverage per bag than the same weight of competing media.

Fewer Bags

More volume per bag means fewer bags to purchase, handle, and dispose of on every job.

Greater Coverage

The same weight delivers 25% more abrasive per truck load versus copper slag — a direct reduction in freight cost per square metre blasted.

Lower Total Cost

Combined with a 15% lower total cost versus garnet at fine grade, the numbers consistently favour Green Diamond across every application.

"Three tubes. Same weight — 5.2kg each. Green Diamond fills the tube. Copper slag and garnet don't come close."

Specific gravity comparison — Green Diamond vs Copper Slag vs Garnet, same weight 5.2kg

From left to right: Green Diamond · Copper Slag · Garnet — all at exactly 5.2kg
