The present invention provides a steel grating including a nonskid unit. The steel grating has an excellent binding power for nonskid paint coated on the surface of a rolling design steel plate formed in the steel grating and improves a frictional force so that a nonskid function is efficiently performed. Therefore, the steel grating enables pedestrians to safely walk and has beautiful design. To achieve the purpose of the present invention, the rolling design steel plate on which a drain hole of various shapes is punched is welded on the steel grating. After the steel grating is washed and dried, the steel grating is preprocessed and dried. A paint for a lower layer is firstly applied on the preprocessed rolling design steel plate and is dried. A paint for an upper layer is secondarily applied on the paint for a lower layer and is dried, wherein the paint for an upper layer is composed of an MMA resin, silica, and an optimal amount of hardeners. |
