Picket fence galvanized steel for highway
Highway guardrail include W-beam guardrail, thrie beam guardrail, cable barrier systems, etc.
W-Beam Guardrail
W-Beam guardrail is produced in standard AASHTO 12'-6" or 25'-0" lengths. Custom lengths and custom post-hole spacing are available on request. Gregory W-Beam guardrail is offered in 10-gauge or 12-gauge steel, four types of finishes, and in pre-curved shapes as part of our commitment to value.
Nova begins with prime steel that matches requirements for quality, physical properties, and chemistry. A multi-stage cleaning process prepares the metal for galvanizing on Gregory's own Modified Sendzimer Continuous Galvanizing Line. Production then pierces the steel with holes and/or slots (to either industry standards or project specifications) and then roll-forms it into the W-Beam profile in one continuous process.
Nova continuously galvanized steel assures a consistent finish while eliminating sharp points and uneven zinc build-up that is typically found in hot-dip galvanized products. While most guardrail is supplied in galvanized finish, it is also available in black, painted epoxy coatings, or weathered steel as alternative finishes for aesthetic applications.
Thrie-Beam Guardrail
Thrie-Beam guardrail is produced in standard AASHTO 12'-6" or 25'-0" lengths. Custom lengths and custom post-hole spacing are available on request. Gregory Thrie-Beam guardrail is offered in 10-gauge or 12-gauge steel, four types of finishes, and in pre-curved shapes as part of our commitment to value.

Cable barrier system
The effectiveness and safety benefits of cable barriers have been proven in China , Europe and much of the United States to help prevent the most serious of injuries from cross-median crashes. Approximately 13% of these cross-median crashes in Nevada are fatal, while over 50% of cross-median crashes result in injury.
DESIGN
The basic design of cable barriers consists of heavy-duty cables strung along a row of posts. The cables are tensioned to provide enough strength and give to safely catch misguided vehicles like a net, thus avoiding head-on collisions. Approximately 30 inches tall, the cable barriers are positioned low to efficiently catch most misguided vehicles around the vehicle chassis, grill and/or bumper and safely redirect them away from opposing traffic.
BENEFITS
- Cable barrier rails can help prevent head-on collisions by catching misguided vehicles like a net and redirecting them in the median area.
- The design of cable barrier is more flexible than concrete barriers when struck, helping to diffuse the crash impact felt by vehicle occupants.
- If hit, cable barrier rails are relatively fast and easy to repair, allowing the Nevada Department of Transportation to quickly and cost-effectively return the roadway to its original condition.
- Immediately following an accident, and even prior to repairs, cable barriers often continue to provide protection against further head-on collisions.
- In the event of a crash that closes the roadway, cable barriers more easily allow for traffic to be re-routed through the median. This can help prevent roadside delays following traffic crashes.
- Cable barriers allow for proper roadside drainage.
- Cable barriers are often less expensive to install than other barriers, providing an effective transportation safety solution at less cost.
