DURALAST® Detectable Warning Plates

 DURALAST® Detectable Warning Plates

Cast iron—the natural choice for ADA compliance

Lower your maintenance and product life cycle costs by using DURALAST Detectable Warnings—your Americans with Disabilities (ADA) and Accessibility for Ontarians with Disabilities Act (AODA) complaint, and environmentally friendly solution.


DURALAST® Detectable Warning Plates by EJ help warn blind or visually impaired pedestrians of the approaching street. Engineered to outlast the sidewalk, this long-lasting cast iron design withstands rigorous urban conditions, such as snow plows, street cleaning machines, and vehicular traffic.

Durable and Cost Effective - DURALAST plates are produced from extremely durable, corrosion-resistant cast iron. An independent lab found the wear index of DURALAST was more than 500 times that of composite warning plates. DURALAST plates are engineered to outlast the sidewalks in which they are permanently embedded; long-wearing plates yield cost savings over the life of the sidewalk. DURALAST also provides ease of installation and compliance. A new interlocking tab design ensures consistent and precise placement every time.

Resistant to the Elements - Cast iron’s inherent resistance to the elements, snow plows, and snow melting chemicals make it a natural fit for severe climates.

Made in the USA from Recycled Materials - With DURALAST, you are eligible to earn LEED® points in the Materials and Resources category. Cast iron is an environmentally responsible product that is completely recyclable after its useful life.

Americans with Disabilities Act (ADA) Compliant - The natural finish of the warning plates meets color contrast requirements. It features a slip resistant textured surface, and is DOT approved (contact your local Sales Representative for specification approvals). Bolting ensures compliance during installation.
