Highway Guardrail Systems for Roadside Safety
Highway guardrail is a critical component of roadside safety systems, designed to reduce impact severity while redirecting vehicles when drivers leave the roadway. It must be engineered to meet federally recognized crash-safety standards, including MASH requirements for performance. Gregory Highway manufactures MASH-compliant highway guardrail products, including W-Beam and Thrie-Beam guardrails and end treatments, for highway and transportation applications.
Highway Guardrail Systems Built for Safety and Durability
Highway safety depends on properly engineered and installed guardrail systems. Gregory Highway’s W-Beam and Thrie-Beam galvanized highway guardrails offer straightforward installation and long service life while meeting or exceeding applicable safety standards. All Gregory Highway safety products conform to AASHTO and ASTM specifications.
We use prime steel in each guardrail design. A multi-stage cleaning process prepares the metal for galvanizing. Our continuously galvanized steel ensures a consistent finish without sharp points or zinc build-up. Looking for a different finish for your highway safety guardrail? We offer black, painted epoxy coatings or weathered steel as alternative finishes for aesthetic applications.
Whether your highway guardrail project calls for weak-post or strong-post, W-Beam or Thrie-Beam, wire rope guardrails, curved or straight sections of guardrail, Gregory Highway products are designed as a system that assures consistency for fast, safe guardrail installations.
We also provide highway guardrail end treatments. Guardrail end treatments (like MSKT) safely absorb crash energy and help complete highway safety guardrail systems for every specification. With standard end sections and energy-absorbing guardrail end treatments for wood post or steel post designs, we can meet your full project requirements. Let Gregory Highway be your expert highway guardrail manufacturer and roadside safety product provider.

Frequently Asked Questions
What is a MASH-compliant guardrail?
A MASH-compliant guardrail is a roadside barrier that has been tested according to the Manual for Assessing Safety Hardware (MASH). MASH testing levels classify how a highway guardrail system performs during impact. Gregory Highway offers MASH TL-3 and MASH TL-5 compliant highway guardrail.
Where are highway guardrails typically installed?
Highway guardrails are commonly installed on road embankments, highway medians, bridge approaches, and near areas with fixed hazards. Guardrails help redirect vehicles from leaving the roadway and reduce the severity of injury during a crash.
What is the difference between W-Beam and Thrie-Beam guardrail?
W-Beam guardrail is the most common type of highway guardrail in the U.S. W-Beam guardrail has a side profile with two waves, resembling a ‘W’, while Thrie-Beam guardrail has a three-wave side profile. Thrie-Beam is stronger than W-Beam, which is why it’s often used in areas with bigger containment risks.
How long do galvanized highway guardrails last?
Gregory Highway’s continuous galvanized steel is manufactured to last many years with minimal maintenance. Unlike batch dipped galvanized guardrail, continuous galvanized guardrail receives a uniform zinc coating that reduces corrosion and better protects the surface from environmental exposure. Continuous galvanizing produces greater consistency and performance over the long term compared to batch-dipped .
What components are included in a guardrail system?
A highway guardrail system typically consists of guardrail, posts, hardware, and guardrail end treatments. These parts work together to absorb crash energy and maintain the integrity of the barrier while redirecting the vehicle safely.
