High-quality cast iron products for urban and industrial use

Reliance Foundry hardscape supplies are designed to work in any setting: from urban infrastructure to residential driveways to industrial environments. Our products include tree grates, trench drains, and detectable warning plates, and serve various functions from protecting greenspaces, offering drainage solutions, to improving accessibility. All hardscape products are made from high-quality cast iron that withstand rigorous conditions with no maintenance.

Reliance Foundry hardscape products are designed and manufactured in the USA, in compliance with the Buy American Act.

Tree Grates

Protect urban trees from the rigor of city life by installing ADA-approved tree grates around their bases. Made from durable cast iron and painted black for a modern, stylish look.

Trench Drains

Water management is a key component of street design. View our heavy-duty trench grates, available in a range of designs from decorative to industrial.

Detectable Warning Plates

Ensure crosswalks and other variable environments are inclusive for all users by adding ADA tactile paving to your project. Available in raw cast iron, or painted yellow for added visibility.

Tree grates

Tree grates protect trees and surrounding soil from pedestrian foot traffic, bicycles, and the rest of bustling urban life. Their attractive, sophisticated features add aesthetic flair to city streets while ensuring that moisture, light, and air are delivered to trees so they continue to thrive. ADA-approved tree grates conform to specific size and shape standards while the slots are designed to create appealing patterns to add style to any location. Tree grates also act as a safe extension of the sidewalk, reducing tripping hazards for pedestrians and other urban traffic.

Trench drains

Trench drain systems prevent flooding of open spaces that are subject to excess surface or rainwater. These can include driveways, sidewalks, parking lots, roads, loading areas, and more. Trench grates collect excess water, ensuring the surface remains safe and dry for pedestrian and vehicular traffic.

Heavy-duty trench grates withstand extensive loads and are ideal for industrial environments such as loading docks and warehouses. Reliance Foundry’s decorative trench drains have the same durability and load capacity as heavy-duty grates, but come in appealing designs for a mix of functionality and style. They are a perfect complement to the aesthetics of modern, urban infrastructure.

Detectable warning plates

Create an inclusive community: make city streets accessible for all pedestrians by using detectable warning plates. Tactile surface indicators signal potential hazards, and mark the transition from sidewalk to street for pedestrians with visual impairment. Reliance Foundry’s detectable warning plates comply with current ADA and ABA guidelines, and are made to last. Formed from durable cast iron, detectable warning plates virtually eliminate maintenance issues and can withstand heavy pedestrian, vehicle, and snowplow traffic without cracking, chipping, or breaking. Whether in their natural rusted patina state, or painted yellow, Reliance Foundry detectable warning plates provide ample visual contrast.

High-quality materials

All Reliance Foundry’s hardscape products are made from durable cast iron. Cast iron has excellent resistance to wear and will stand strong in any climate. It is low maintenance and ideal for use in any environment, from industrial to residential to parks. Due to the casting process, cast iron has a high coefficient of friction that provides a safe, non-slip surface. This is especially important for hardscape as it is often exposed to water and snow, and surfaces must remain safe for pedestrians and vehicular traffic.

Painted finish

Cast iron trench grates and tree grates are finished with resilient black paint. Black adds a stylish, contemporary look to hardscape supplies placed in urban environments. Reliance Foundry’s high-performance paint finish provides a thick, uniform coating that has superior corrosion resistance. It is specifically designed not to crack, chip, or peel, and offers a hard, protective layer against harsh outdoor elements.
