Product Overview

Steel bar grating is an open grid assembly of steel bars known for its high strength and robust structure. It consists of bearing bars with greater cross-sectional depth than width, held at equal parallel spacing by cross bars. The construction type is determined by how cross bars are attached.

This extremely strong and durable grating is ideal for load-bearing applications including pedestrian and light vehicle traffic. Available in various bearing bar spacing, depths, and widths to meet specific load requirements.
