Fabricated Metal Trench Grates
Fabricated metal grates are combinations of surface plates and load bars. The surface plates are cut or punched to the desired pattern and size. Load bars are cut and welded to the back side of the plate to add strength. Finally the fabricated metal trench grates are finished with galvanizing, painting, powder coating, electro polishing, sand blasting, brushing, or other finishes.
The Dura Trench difference is the highly automated process used to manufacture our fabricated trench grates. We use a variety of in house CNC equipment to process the bars and plates, then use robotic welding to ensure high quality connections, and finally use automated sandblast and surface finishing equipment. This ensures high quality and consistent products at high production rates.
A fabricated metal trench drain grate can reach any load class. We do this by first working with our engineering team to accurately model the trench grate. The trench grate is load tested using finite element analysis to ensure it will meet the required load rating. Plate thickness, hole spacing, bar size, and bar quantity can all be varied until the design requirements are met. The individual trench grate components are then output to our CNC equipment for cutting and programming of robotics and finishing. The process ensures high quality grates meeting the customer's specifications.
Because fabricated metal trench grates are fabricated in house with CNC equipment it also allows a lot of design flexibility. We can work with many types of metals including carbon steel, stainless steels, brass, bronze, aluminum, etc. We can cut openings of any size or pattern to meet your design requirements. Trench grates can have ADA compliant openings, heel proof openings, or some other type of ornamental pattern openings. We can customize trench grates with logos or architectural details as required.
Finally, fabricated trench grates can be finished in a number of ways. If they are steel it is common to powder coat the grates. Black is common, but other colors can be utilized for that perfect look at a budget friendly cost. Steel trench grates can also be hot dip galvanized for long lasting durability. If it is an architectural trench grate application and high grade materials are utilized then the finish can be polished, brushed, or sandblasted to give the appropriate amount of shine or texture.
