Floor Drains

The primary purpose of any floor drainage system is to remove water as quickly as possible in a controlled and predictable way.

Frost gratings and covers are designed to suit the wide variety of modern floor finishes such as ceramic tiles, resin floors, sheet vinyl and concrete. We offer nickel bronze, stainless steel and ductile iron to allow aesthetic choice.
