Multiple Grating Options
The 1200NGB and 1200 Series Catch Basins offer an extensive selection of grating. Domed atrium grates (green, black) are available for pedestrian applications while the ADA compliant polyolefin slotted grates (gray, black, green, sand) are rated for light vehicle traffic. Stronger still, the galvanized steel slotted and cast iron slotted grates are built to withstand commercial loads. A pedestrian rated bronze frame-grate option fastens to the catch basin body and is heel-proof, and NDS also offers a solid plastic cover for sump box applications.
There are a broad variety of decorative cast iron grates available in either their natural raw finish or a baked on oil finish (BoOF). Be aware that although a raw grate may arrive in a silver/gray color, it will quickly begin to naturally rust the moment it is exposed to any form of moisture and will appear bright orange before settling to brown. The timing of this process varies and could take up to two years. However, BoOF is a pre-rusting process which seals in a natural chocolate brown weathered appearance that bypasses the initial rusting stages.
