Types of Metal Safety Bollards

There are several options available when selecting metal safety bollards for your site. The materials used can be cast iron, stainless steel, or aluminum. This article will discuss some of the different types of metal safety bollards and their properties. You can also choose from a variety of styles and designs.

Stainless steel

Stainless steel metal safety bollards are the ideal option for a variety of locations. They offer high resistance to rust and are easy to maintain. Additionally, stainless steel bollards are relatively inexpensive to purchase and install, reducing the overall costs. Moreover, stainless steel bollards have a stylish and sleek appearance, which can enhance the look of any property.

Stainless steel bollards are available in two types, with Type 304 stainless steel being used for moderate-exposure areas while Type 316 is suitable for harsh environments. Both types are effective for a variety of purposes, including safety and security. The surface of these bollards can be polished to either a #4 or a #2 finish.

Cast iron

Cast iron metal safety bollards are used to establish a protective barrier around urban spaces, buildings, and parking lots. They are available as surface or subsurface mounted products. These bollards are typically made with an ornate design and are designed with eyeholes for chain or rope attachment. They do not come with padlocks. The base of the bollard is cemented into the ground with a socket. A cover plate is then installed to protect the hole.

Cast iron bollards have a long lifespan. They last for more than 100 years. Their weight is much lower than traditional cast steel bollards and are easy to install. They also reduce the risk of injury caused by improper lifting.


Decorative bollards are a great way to direct traffic, limit unwanted access, and organize a busy parking lot. They come in a variety of colors and styles to fit your specific design needs. Heavy-duty cast aluminum bollards are available in 5″ or 8″ diameters. Many have decorative ridges that add design and architectural detail to any environment. Bollards are manufactured using state-of-the-art techniques that seal joints. They also come in either a gloss or textured polyester powder-coat finish.

While steel is the most common material for bollards, stainless steel is another durable and attractive material. This metal is highly corrosion-resistant, and is also more lightweight than standard steel. Stainless steel is also very durable and will take powder coatings with ease. Steel pipe bollards are another excellent choice for safety and security. They can be primed or covered with a protective sleeve to reduce rusting.


While traditional bollards are designed for smaller impacts that damage surfaces, knock-down bollards are designed to withstand larger impacts. They are often used on highways and in heavy traffic areas. Depending on the type of vehicle impact, knock-down bollards can be either removable or permanently installed.

Stand-alone polyethylene bollards are often used in construction and parking applications because of their low cost and low maintenance. Their visual impact is similar to that of their metal counterparts, but plastic’s strength shines through in their covers. These covers can be custom-made in a variety of styles, from traditional to modern.
