ST-38A - 3/8 inch - Stainless Grating with Treads

The ST-38A 3/8 inch Stainless Steel Grating is a low-profile foot grille with added Carpet Treads for adding scraping and absorption and color. This 3/8 inch Stainless Steel Grating was designed to offer superior durability and striking architectural design. Uniquely, in addition to the sleek and durable stainless steel rails, ST-38A includes either a Nylon Carpet or a Polypropylene Bristle inserts at every 4-1/2″ on center. These added inserts dramatically increase the scraping and absorption capabilities of the typical stainless steel and offer the opportunity to customize the final aesthetic of the grating.  The entire ST-Series is constructed with tough 304 Type Stainless Steel and is built to withstand up to 1,000 pound rolling loads and incredibly heavy traffic patterns. Stainless steel treads are spaced at .233″ on center allowing for debris scraping capabilities and safety for high-heel traffic. Specify the ST-38A 3/8 inch stainless steel grating with treads where a super durable, highly customizable high-end foot grille with a low-profile is desired.
