Roadway Gratings

Borden’s roadway gratings are trusted and installed across North America, especially on Bascule (lift) bridges where strength and airflow are critical. These gratings are designed with an open pattern that allows up to 80% free air passage, offering a strong yet lightweight solution.

Product Options and Benefits

Rectangular Roadway Gratings
A cost-effective option, offering the highest level of open area for air and water flow.

Riveted Roadway Gratings
A cost-effective option, designed for added lateral support, these gratings use a crimped design that acts like a truss. The crimp can be slightly raised to ensure a smoother, more comfortable ride.

I-Bar Roadway Gratings
These provide the best strength-to-weight ratio among all Borden products. Available in several styles:
– Standard Rectangular
– R/W-I (with truss-like crimp)
– Concrete-filled for added durability

Engineering Considerations

Design tables are available to help engineers meet strength and deflection requirements. Fatigue performance should be evaluated based on the specific needs of each project.
