Metal guardrail for low speed roadway
Metal guardrail for low speed roadway
(OP)
Can a W-beam metal guardrail be installed without the end anchorage (concrete block) for a low speed (10 mph) road? The purpose of the guardrail is to protect vehicle from falling off a drop off and lands onto a fuel tank.

If you absolutely don't want anchors, see if box beam railing is available in your area. I think it's used mostly in Wyoming and NY, and may be hard to find outside those states. That system works by bending the box-section railing rather than in tension. Standard deflection is five feet, and minimum run length is 125 feet. It needs to be shop-curved for radii under 725 feet. It's more expensive than heavy-post W beam.
