Guardrail

W-Beam Guardrail

Time uses W-Beam guardrail that is produced in standard AASHTO 12'-6" or 25'-0" lengths. Custom lengths and custom post-hole spacing are available on request.  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.

Our manufacturer, Gregory Industries, 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.

Gregory’s 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 Gregory guardrail is supplied in galvanized finish, it is also available in black, painted epoxy coatings, or weathered steel as alternative finishes for aesthetic applications.

Gregory W-Beam guardrail is manufactured to AASHTO specifications in M-180 Class A or B, and finish types 1, 2, 3, or 4.  Every piece of guardrail is stamped with a brand registration that is repeated throughout the entire length of the rail.

MGS Midwest Guardrail System

Time now offers the W-Beam Barrier for the Future!

Existing W-Beam barriers were developed many years ago when the vehicle fleet was different than it is today. These existing W-Beam barriers measure 27 5/8'' to the top of the rail.  When crash tested with today's higher center of gravity vehicles, many results have not been successful.

The differences between the MGS Barrier and the older W-Beam barrier is:

  • The MGS top of rail height is 31'' rather than 27 5/8''.
  • The MGS blockout is 12'' rather than 8''.
  • The MGS W-Beam rail splices occur mid span between posts rather than at the post.

In 2001-2002, the Midwest States Pooled Fund Program funded by 11 States recognized the need for a new generic strong post W-Beam barrier that would be compatible with the newer higher center of gravity vehicles crash tested under NCHRP 350 Test Level 3 conditions.  The result was the MGS Barrier.

Convex and Concave Guardrail

Rail sections to be installed on curves having a radius of 5 feet to 150 feet can be curved at the manufacturer's facilities prior to project site delivery. Rail can be curved either convex or concave as required. Terms "convex" or "concave" refer to the direction curved, inward or outward, relative to the traffic face of the rail.

End Sections

We can supply complete highway safety guardrail systems for every specification.  We can meet your full project requirements with standard end sections and energy-absorbing end treatments for steel post designs.  We can also recommend safety solutions that meet the specifications for your project.
