For sale is a HEAVY DUTY WELDED STEEL FLOOR GRATE 24 x 18 x 2 1/4 INCH. This is the heaviest built industrial floor or drain grate available, period. Dimensions 24 x 18 x 2.8 inches. Weight 67 lbs each. They have minor rust on them, they will not fit your dining room, but they will work great at your factory and will withstand a lifetime of extreme abuse. Due to weight, combined UPS shipping is not available, shipping two is twice more expensive than shipping one. However, for multiple purchases, I can arrange freight shipping. I charge $10 per pallet plus actual shipping, you can use my quote (and pay me) or your own carrier (you pay me only $10). Free local pick-up. Similar grates sell for $280 new.
