Reliance Foundry uses top-quality materials in all its bollard products to ensure long-term service life for a range of decorative and utility applications. All bollards are made from fully recyclable materials and require a minimum amount of maintenance.
Compared to iron and steel, aluminum is a lightweight material ideal for removable applications. Aluminum is also highly castable, making it useful for a range of decorative and ornamental designs. Exposed aluminum naturally oxidizes to form a discreet barrier against further corrosion—making it suitable for more corrosive, high saline environments. Aluminum is used in architectural and decorative bollards.
Concrete bollards offer a clean, natural finish featuring exposed aggregate from the Pacific Northwest. Concrete is easy to mold, making it suitable for a range of decorative designs. Bollards use high-pressure cement to ensure the best strength and durability to prevent chipping and wear.
Ductile iron offers a high level of castability, which makes it especially suitable for ornamental products featuring more intricate shapes and textures. Unlike standard cast iron, which is brittle in nature, ductile iron is made using small amounts of magnesium or cerium to manipulate carbon into forms that won't compromise integrity under stress. The result is a metal with high impact properties and resistance to long-term fatigue. Ductile iron is used in many architectural and decorative bollards.
Stainless steel offers a structural versatility similar to standard steel—but with a clean metallic aesthetic and exceptional resistance to corrosion. Stainless steel products are manufactured from 316-grade stainless steel—designed especially for marine applications and resistance to chemical corrosion. Stainless steel offers a bright and partially reflective surface—making it an ideal complement for many existing building and landscape designs. Stainless steel products can be powder coated to match site aesthetics and/or to increase resistance to corrosion.
Steel is a versatile material suitable for a range of applications. It is exceptionally strong and is often used for structural support in buildings and large transportation infrastructure. Steel bollards are machined from prefabricated materials. They offer a more economical solution while providing high-end, uniform finishes suitable for any contemporary building or property. Standard steel bollards are powder coated in 1 of 6 standard colors to increase visual quality and to protect against corrosion and wear. Standard steel is used in removable, fold down, bike parking, architectural and decorative bollards.
Structural grade steel
Steel pipe security bollards use ASTM 500 B structural grade steel to offer a high degree of impact protection. Steel pipe bollards come coated with primer and should be painted or covered with a protective sleeve to prevent corrosion. An engineer should be consulted for site-specific security applications.
Polyethylene is a durable material used for a range of applications. When used outdoors, it won't fade or chip, and it will resist marking from collisions and chemical wear from solvents and de-icing salts. Polyethylene offers an economical means to providing long-term protection for security pipe bollards against corrosion and wear. Polyethylene is used in standard utility and decorative plastic post covers.
Polyurethane is a versatile plastic material that will give way to vehicle impacts—bending up to 90 degrees—without losing its shape. Polyurethane will resist scratches and dents, won't fade from ultraviolet sun exposure and will show minimal marking from vehicle collisions. Bollards made from polyurethane also minimize damage to vehicles in the event of a collision. Polyurethane is used in flexible bollards.
