Expressway Guardrails

Expressway Guardrails include Posts, Beams, Fasteners, end Treatments, and
other Accessories
Expressway guardrails are safety barriers used mainly along highways and
expressways to protect drivers from obstacles and prevent vehicles from leaving
the roadway. They are usually made from galvanized steel, which is strong but
lightweight, and cost-effective compared to more robust materials like
concrete.

Expressway guardrails are designed and manufactured to ensure the safety of
roads and highways. The components of guardrail systems include posts, beams,
fasteners, end treatments, and other accessories. Expressway guardrails
typically come in sizes of W-beam, Thrie-beam, and box beams. These guardrails
are usually available in lengths of 6m, 9m, 12m, and 15m and are also available
in different widths, depending on the type of guardrail. W-Beam guardrails have
a basic design shape of two waves, while Thrie-beam guardrails have three
waves. Box beams are composed of two flat pieces of sheet metal connected with
posts and beams.

Maintenance and service life of expressway guardrails depend on the type of
guardrail system, its location, environmental factors, and levels of traffic.
Generally, guardrail systems require periodic inspections and repairs, as
needed. Proper maintenance and timely repairs will help ensure that guardrail
systems remain safe and in good condition for many years.

Expressway guardrails are used for highway and expressway traffic safety
purpose. W beam and thrie beam are available. Finishes of expressway guardrails
are normally hot dipped galvanized.
