fashionable black metal quartz showroom racks st-21
Humidity in stone warehouses can be extreme. The 21 powder coat is applied at 90-110μm thickness — more than triple the industry minimum — with a zinc phosphate undercoat for corrosion resistance.
21 Product Overview
Stone importers tell us their biggest display headache is racks that develop a permanent lean toward the front. The 21 has full-frame gusset plates at all four corners specifically to prevent this.
Natural stone slabs are heavy, irregular, and expensive to replace. The 21 was engineered around those realities — load-tested to 120kg per slot with a safety factor of 2.5.
We manufacture the 21 with frame tolerances borrowed from industrial pallet racking. Not because display stands belong in warehouses, but because wobbling is unacceptable when presenting a $3,000 marble slab.
The 21 contact pads are made from EPDM rubber — the same material used in permanent outdoor gaskets. They won’t degrade, stain, or transfer color to light-colored stone surfaces.
