Guide Rail Examples:
A guide rail serves to provide a safety barrier that is used to prevent a driver who has veered off the roadway from hitting objects beyond the guardrail.
The guardrail face functions to guide the vehicle back onto the road. The end terminal or the exposed end of the guardrail is outfitted to absorb energy. The impact head slides down the length of the guardrail, flattens, and redirects the guardrail away from the vehicle until it comes to a complete stop.
There are three types of guardrails, including W-beams, standard highway, and traffic safety rails; Bolt-on, durable and inexpensive guardrails where rails are bolted onto the posts; Drop-in, feature brackets to slide the post onto the structure allowing for access to guardrail protected areas.
Guide rails are commonly used for applications such as protecting equipment from forklift damage and other industrial safety applications, preventing or minimizing accidents on roadways, protecting buildings from damage, protecting pedestrian walkways and providing barriers for transformer or workstation areas.
They can also be used for fencing for private installations, parking lot barriers, and work-zone safety installations, and more.
Guardrail life expectancies will vary. If the guardrail is hit often, it will likely need to be replaced sooner rather than later. The advantage of guardrails is that they are modular, meaning when one piece is damaged, you only need to replace that section, not the entire guardrail.
A small dent or ding here and there will not affect how your guardrail performs. However, if your guardrail has bent posts or vertical tears, it is likely you will require repairs or replacement parts to ensure the guardrail is functioning at its best.
Generally, the cost of a guardrail installation is roughly $4-$6 per foot. For each ton of highway guardrail, the cost is roughly $570 to $630. There are a variety of factors that affect the cost of your guardrail installation, which include the cost of permits, parts, grading the land, utilities, labor, and the type of guardrail you choose. For example, bolt-on guardrails can be less expensive than W-beams.
