Crafted from premium Class 35 exterior-grade gray iron, our cast iron plates are engineered for extreme durability. Snowplow-resistant, they provide long-term, reliable performance, even in the most challenging environments.

Our unique interlocking system allows for seamless connections between adjacent panels. With a vent hole on top to release air and ensure secure embedment, these panels are designed for effortless installation. Their lighter weight makes for faster, easier setup, saving time and effort on every project.

Our products meet or exceed the standard specification requirements of AASHTO M 333-16 for detectable warning surfaces. Featuring truncated domes with a nominal height of 0.2”, diameter of 0.9”, and 2.4” center-to-center spacing, they are designed for full compliance. With pedestrian-safe slip resistance ratings of 1.27 (dry) and 0.72 (wet) per ASTM C1028, these surfaces ensure safety in all conditions.

Our products naturally weather to a maintenance-free patina finish, offering an attractive and long-lasting appearance that blends seamlessly into any environment.
