Low profile secondary containment platforms. Long lasting EcoPolyBlend™ polyethylene is nearly impervious to chemicals, including acids and corrosives. Seamless design to ensure any leaks or spills are captured in the sump, before they reach floor drains or create a slip hazard. Sturdy grates are nearly 2-1/2" (64mm) thick for superior crack resistance. Self-locating, they reduce the chance of grate "ride-up" and remove for easy cleaning
