Stainless Steel Trench Drain
All standard Unitherm Trench Drains are fabricated of 14 Ga. Grade 316 stainless steel. Standard drains come with perforated stainless steel pedestrian grade grating of 12 Ga (for extreme duty loads ½” thick solid plate option is required). All welds are done using TIG technique with 316 rod, polished smooth – crack and crevice free. Concrete anchors are welded to the parameter for a solid installation. The inside dimension across the width of the grate is 6” and the start depth of each section is 3” with a .125” fall per linear foot of trench from the shallow end(s) to the collection point. Please note lengths up to 40’ can be shipped. Longer lengths can be accommodated but will require a “field” weld for final installation.
