Press-locked steel bar grating manufactured through a precise process of slotting, pressure lock plug insertion, and finishing. At the intersection points of flat steel and horizontal poles, the horizontal pole is pressed into the loading flat steel and securely fixed. In some configurations, flat steel may also be used for horizontal poles.
This versatile grating system is widely used for:
