Commercial Drainage Systems
MasterBuilder Mercantile offers floor drains, roof drains, area drains, trench and channel drains, industrial floor drains, scupper drains, cornice drains, and shower trench drains, along with replacement grates and drainage accessories.
A floor drain typically collects surface water directly from the surrounding floor. A floor sink is commonly used as an indirect waste receptor, receiving discharge from equipment through an air gap or air break where permitted by applicable plumbing codes.
Consider the application, required drainage capacity, outlet size and connection type, grate material, expected loading, floor construction, and any applicable plumbing-code requirements. Manufacturer specifications should be reviewed before selection.
An area drain collects surface water at a localized point, typically through a square or round grate. A trench drain uses an elongated channel and grate to collect water across a wider linear area.
Drain Grates & Replacement Parts
Start by identifying the drain manufacturer and model number. Check for casting numbers on the existing grate, then measure its actual width, length or diameter, thickness, and seating profile. Compare these details with the manufacturer's replacement-part specifications before ordering.
Yes. Many commercial floor and area drains have removable grates that can be replaced independently, provided the existing frame and drain body remain in suitable condition and the correct replacement component is available.
Drain sizes often refer to the nominal frame or drain-top dimensions rather than the removable grate. For example, the Zurn P150-GRATE used with the 14-inch Z150 promenade drain measures approximately 12-13/16 inches square. Always verify actual replacement-part dimensions.
Commercial drain grates are commonly manufactured from cast iron, ductile iron, stainless steel, bronze, or other materials depending on the drain model. Material selection depends on loading, corrosion exposure, appearance, and application requirements.
