A grating is a metal lattice used to cover sewer holes. Because it is lattice, it drains water easily. At the same time, it is a cause to block the flow of the sewer by the accumulated cigarette butts and garbage. In some cases, rods of older people or wheels of strollers are stuck in and in some other cases, it gets broken by heavy vehicles. 


Introducing DSP Design Grating

Established in 2019, N Tech has succeeded development of a new concept steel grating ‘DSP Design Grating’. DSP stands for Design Steel Plate). It is consisted of 之 configure, end bars and filter plugs. The patented 之 configure has strong resistance against heavy weight and has strong supporting power. This improves the load-bearing performance due to drainage holes with burring, and it also performs well under static load, localized load, horizontal load, and fatigue repeated load. This creates an embossed surface on the grating to prevent slipping. This configuration was produced with the technical support of the Korea Institute of Science and Technoloyg Information and has been fully verified for structural adequacy and stability.

The filter plug has a patented technology for combining an anti-dirt filter with an individual filter insertion method. It is a high-strength engineering material that is certified to be vandal-proof and has an excellent drainage capacity in relation to dirt prevention. It is a high-strength PC material that is certified for impact strength at minus 30 degrees Celsius and is available in various designs, as well as road accident prevention with color and photoluminescent filters. The endbar is a component made up of multiple components arranged by length and then welded together to form an integral unit.

Excellent drainage, strength and safety

DSP Design Grating is highly drainable. Unlike conventional comb-type gratings, only rainwater drains through the spigot while preventing dirt from entering, and its drainage performance has been certified through authorized tests. The sturdy construction makes it hard to break or deform, and the narrow gaps prevent items, canes, and stroller wheels from falling out. DSP Design Gratings can be patterned to blend in with the surroundings. Filter plugs of different colors can be combined in the appropriate places on the body. The company has also developed DSP Design Gratings with solar light emitting modules. The protruding modules improve lane identification in low-light conditions.
