ABOUT THE 4″ SCH 40
Light Duty Bollard: Not to be used to stop vehicles.
4-inch Schedule 40 Steel Pipe Bollards have a 0.237″ thick wall and can be used for non-critical, light duty bollard applications only. Smaller pipe sizes like this should only serve to delineate, to hold signage or chains or as protection from light machinery impacts. If impacted with an ecomony car at 5 mph, the pipe will easily shear or bend and pull up and tilt the footing. These should be considered light duty bollards.
At only 86.5 lbs for an 8-footer, they can easily be set into place with a single worker by hand, all while drinking a Rockstar.
GENERAL APPLICATIONS: The 4″ SCH 40 Pipe:
- might be used as protection for objects or building corners from collision by light weight machinery at best.
- may be utilized as delineators (visual queues) to drivers for traffic control where, if omitted by collsion, does not present greater problems than if it did not exist.
- may be used to hold non-critical signage like “reserved parking” for instance; not to hold stop signs for instance.
- can be used as stanchions for crowd control or queue line.
- as fixed immobile delineators.
- may be tall to hold signage high.
- SHOULD NOT EVER be used to protect people, or anything else for that matter, from vehicle impacts, even at low speeds.
- SHOULD NOT be used as a barricade or for building entrance protection.
AS A BARRICADE: Nope, not even close. At minumum, use a 6-inch Schedule 40 pipe or maybe the 5″ Schedule 80 pipe. To have more certainty in a barrier’s stopping force, it is advised to use an impact-rated bollard system such as the C40, K4 or K12.
VARIETIES: ASTM A500 Carbon Steel Pipe is the common go-to choice for bollards. Although, it is sometimes sufficient to use a structural grade untested pipe. Of course, we also offer pipe that meets various prescribed ASTM and ASME standards. See “Pipe Varieties” below.

PIPE SIZES EXPLAINED
Confused about "Schedule" or "Standard" wall thicknesses? See this short article.
This Pipe may be available in the following types and grades:
Electric resistance weld (ERW), seamless (SMLS), and double submerged arc weld (DSAW) in all published schedules and walls, Grades ASTM A-500 GR A & GR B, ASTM A-53 GR B, ASME SA-53 GR B, ASTM A-106 GR B, ASME SA-106 GR B, AP1 5L X-GRADES, ASTM A-252 GR 1, 2, AND 3, ASTM A-139 GR B, and ASTM A-501.
UNTESTED PIPE VARIANT
This pipe may also be available as untested pipe without an ASTM rating. It is then referred to by Diameter and Wall Thickness only; no Schedule #, Standard, XH or XXH etc. Untested pipe can be much cheaper, and is often perfectly fine for bollard applications since the testing is really about pressure testing; how much PSI the pipe can withstand when filled with a pressurized liquid or gas. Bollards are just filled with concrete, so PSI ratings are generally not applicable. Their may be a small or negligable weakness in terms of bollard strength associated with untested pipe.
