ADA compliant and heel proof perforated galvanized steel grate - 3" wide x 24" long x 0.5" thick  - rated for DIN load class B.
 
This 3" wide trench drain grate is used where ADA compliance and heel compliance are a priority but the budget simply won't allow for stainless grating.  It is typically used on a 2" wide prefabricated trench drain.  The small openings are more prone to clogging, but will provide adequate inflow when properly maintained.  This trench drain grate is made of a heavier gauge galvanized steel than most competetors to provide a longer service life.  Typical uses are trench drains in pedestrian walkways, patios, plazas, parks, commercial buildings, and balconies.
