Steel Pipe Bollards

> Request a Quote on Bollard Pipe Below

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. Finally, 10″ Schedule 40 Pipe and 12″ Standard Pipe can be used for Heavyweight Entrance Barriers.

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.

What Pipe is for What Purpose?

The most commonly installed pipe bollard may be the 6″ Schedule 40 Steel Pipe Bollard.

The smaller 4″ is often seen installed in non-vehicle collision protection situations. For instance,  to protect a building corner from forklifts or machinery from carts. The 4″ should not be used to try to stop an errant vehicle.

The 5″ Schedule 80 Pipe may be close to the 6″ Schedule 40 Pipe in strength.

The 8″ Schedule 40 is used where even greater impact resistance is desired.

10″ or 12″ are sometimes used for staunch building entry protection for the fact that they hold a lot of concrete.

In all, the sizes typically used for bollards are 4″, 5″, 6″, 8″, 10″ and 12″ and each in Schedule 40 and Schedule 80.

Independent In-Ground Pier Installation

For in-ground bollards, footings may vary, but typical for all is that the Pipe extends nearly to the bottom of the footing, but should be suspended off sub-base with a masonry chair. 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 any potential local codes, the staunchness desired and the verified clearance of any utilities.

Trench Installation

For barrier security applications, bollards are placed a minimum of about 5′ or less apart to stop vehicle entry, and no less than 3′ apart for ADA compliance. Using 8″ Pipe (or larger) further increases the stopping power of the system. In most situations, it makes more sense to dig at least a shallow trench since individual footings would leave little undisturbed soil between them. Especially with barrier security lines, a long rebar enforced cage can be placed in the trench. Rebar lengths can also be embedded within bollard concrete which makes the bollard itself stronger.

If your goal is to protect buildings and people from errant vehicles and ram raids, and you’re on a budget,, think bigger pipe, thicker wall and reinforced concrete, and more concrete. Another option is to look at our traffic impact bollards. The C40 is actually quite affordable, while the more robust K4 and K12 can be considered cheap when you consider the cost of a human life.

Alert: Galvanized does not hold paint worth a darn because it's acts like a non-stick frying pan, so don't choose galvanized if you are hoping to paint pipe. Leave galvanized be, or cover it with a bollard cover, don't paint it!
Structural ASTM A500 Grade A is often typical. Untested and Rejected pipe doesn't necessarily meet fluid pressure tests, but is usually OK for bollard applications that aren't critical.

You must have a way to receive delivery. Trucks don't usually come with a fork and pipe has to be forked from the side of truck. Smaller pipe under 150 lbs can be offloaded by hand, but the driver may not be happy about it. Note: "Forks" is short for forklift, Lull, Track Loader with forks, Skid Steer with forks etc.
