Steel Pipe Bollards

Steel Pipe Bollards come in many flavors. The most common ones for parking lots are the 6″ Schedule 40 Pipe Bollards. 4″ and 8″ Schedule 40 can be appropriate for various applications. Schedule 80 Steel Pipe has a thicker wall, so 4″, 5″ and 6″ can be used to deliver more strength in a more compact form. In fact, we have a great deal on 5″ Schedule 80 right now!

If impact rated bollards are desired, see our traffic impact bollards page.

We also supply Base Plate Bollards, or Bumper Posts, that are surface installed with anchors. These are great for inside a warehouse or exterior locations where an in-ground installation is prohibitive or not necessary.

$90 5" SCH80 Bollard!


We have a distributor who has bought out a large lot of 5″ Schedule 80 Pipe. This pipe is heavier than 6″ Schedule 40. While supplies last, we are offering 7′ long 5″ Schedule 80 Pipe for $90 each, with discounts for quantities. They are freighted out of Detroit. As an example, freight for one dozen to Minnesota is about $350. Email sales@stpaulsign.com for a quote.

Schedule 40 Pipe Bollards

Most commonly installed is the 6″ Schedule 40 Pipe. 4″ is often installed in non-vehicle collision protection situations. For instance,  to protect a building corner from forklifts or machinery from carts. 8″ is used where greater impact resistance is warranted. Sizes available include 3″, 3.5″, 4″, 5″, 6″, 8″ which cover the conventional bollard applications.

Independent In-Ground Installation

For in-ground bollards, footings may vary, but typical for all is that the Pipe extends to the bottom of the footing. A typical 6″ bollard application might have 48″ under finish grade in a 48″ deep footing of 18″ diameter, and then have 36″ to 48″ above finish grade. So this requires pipe to be cut to 7′ or 8′, respectively. Footing depths depend on both local codes and the staunchness desired. 

Trench Installation

For barrier security applications, bollards are placed 5′ or less apart to stop vehicle entry. Using 8″ Pipe (or larger) further increases the stopping power of the system. In most situations, it makes more sense to dig a trench since individual footings would leave little undisturbed soil between them. Especially with barrier security lines, a long rebar enforced cage is often placed in the trench which also helps nicely lay out and plumb the bollards.

If designing an impassable barrier is the goal, take a look at our traffic impact bollards.

Schedule 40 Pipe Weight

In regards to in-ground installations: It is worth noting that a 6″ Sch 40 Pipe 8′ long weighs about 152 lbs. Along with 1/3 yard of concrete in the footing, the system is around 1200 lbs.

Schedule 80 Pipe Bollards

For beefy in-ground installations, Schedule 80 Pipe has a thicker wall for greater resistance to bending or cracking in the event of a collision. There is also Schedule 160 and XXS which are even thicker yet, but are rarely if ever used as conventional bollards. You may more commonly see Schedule 80 Pipe used for 4″ and 5″ Pipe Bollards to yield a similar strength as Schedule 40 6″ in a more compact form.

Barrier Protection

Typically, if you are looking for greater stopping power, it is better to use an impact rated bollard rather than just going bigger and heavier. Theoretically, Schedule 80 Pipe may be part of that plan, but definitely start looking at impact rated bollards.

Is a Heavier Wall Better?

It’s not just the thickness of the steel that makes for more stopping power. It may be better to use a larger diameter pipe that holds more concrete. It’s hard to say what plays a more significant role, wall thickness or diameter. That’s why they have ASTM impact rated bollards.

Steel Types and Finishes

Bollard Steel Types

Schedule 40 pipe can be the conventional Carbon Steel, COR-TEN or Stainless Steel. The ongoing battle with carbon steel bollards, which are the cost-effective way to go, is that they rust, especially outdoors. Painting them can be an endless chore though, a finish is necessary to counter most of the rusting. We always suggest a Bollard Cover after painting. Alternatives are COR-TEN is cool if you like the rusty look, and Stainless Covered Carbon Steel Bollards for more corporate settings.

Steel Pipe Bollard Finishes

Our Steel Bollard Pipe comes in raw, factory primed and galvanized. Finish painted and powder coated options are not offered because the finish would suffer greatly in shipping. These finishes are handled on the installer’s end.

Base Plate Bollard Finishes

Base Plate bollards come from the factory as Raw, Galvanized, Primed, Finished Coated or Powder Coated.

Factory Red-Primed Schedule 40 Pipe

And the Best Bollard Solution is…

In-Ground Installed

For in-groud installations of typical parking bollards, the best way to go is to use a regular carbon steel pipe bollard, slap it with protective paint, and then use a bollard cover. We sell standard and decorative bollard covers and bundle the pipe and cover together for better pricing. 9 times out of 10, this will be a 6″ Schedule 40 Pipe Bollard.

Surface Installed

For surface mounted bollards, the Base Plate Bumper Post Bollard is really the only way to go. All finishes are available from the factory, and there are hundreds of bollard cover colors and styles to choose from. The pipe size and height will be whatever works best for your application.
