W-beam guardrail has a section or profile of W shape, it is also named as two wave beam guardrail. This is the major type of beam barriers for highways safety with symmetrical designs on each side of the beam. We supply two kinds of finishes for W beam guardrail panels: hot dipped zinc coating or plastic coating. According to the fabricated shapes, our W-beam guardrails can be divided into two types: the straight line w-beam,or the curved beams.
How to choose straight W beam or Curved Beam used for your uses?
The straight W-beam guardrail can be lined up for transitioning smoothly and is suitable to the curves with a radius greater than 45m. For the radius less than 45m, the pre-curved W-beam guardrail product exploits its advantages to a full.
W beam guard railings can be used in expressway and highways to absorb maximum energy of the impact force when collision occures and reduce harms to cars and people. It can also protect the vehicles against skidding off roads, especially mountain roads and bridges and prevent the pedestrians from the danger of walking across highways.

W-Beam Guide Rail comes in standard 12’ 6” or 25’ sections. This is the most frequently used type of guide rail on our nation’s roadway system. It is a roll-formed product that is shaped out of steel coil into the shape of a “W,” and typically galvanized to prevent corrosion and increase the product’s life-cycle. W-Beam Guide Rail can be installed on steel strong posts or weak posts, using a variety of different post spacing options, depending on the specific situation (typically 6′ 3″ spacing). Some states also specify wood posts for installation. W-Beam Guide Rail can be ordered with the traditional galvanized (gray) coating, Corten (rustic brown) style, or poly coated in a variety of colors to match your specific aesthetic criteria. The W-Beam, consists of two “humps” and one”valley”. Humps are rises that face towards th traffic (convex surface) lane, while the valley (concave surface) points away from the traffic lane. The W-Beam, guardrail measures 13’ 6.5” in length, 12.25” in height, and 3.25” in depth. The lay length of the 13’ 6.25” guardrail is 12’ 6”. This lay length represents the distance between the outermost post holes. Thus, a 12’6” panel has post holes centered at 6’3” apart. The thickness of the W-Beam, Guardrail is 12 gauge or roughly .125” thick. The W-Beam Guardrail can be purchased for both straight and curved roads. National Highway Products, Inc. offers several types of end treatments including the single buffer, double buffer, and flared end. Both the single and double buffer ends measure 16.25” in height and 24” in length, with a radius of 6.3125”. A flared end measures 27.5” in length, 15.375” in height, and 9” in depth. Typical installation consists of a panel of guardrail attached to posts that have been pounded into the ground. These posts are 4” wide, either 6” or 8’ in length, and 6” in depth. The posts are spaced at intervals corresponding to the number of punches in the guardrail panel. Therefore, a 12’6” piece of guardrail at 6’3” post spacing require 2-3 posts, depending on the need for a center post.
