Product Description
W Beam Galvanized Guardrails
W-beam guardrail is a kind of road crash barrier used for securing highway safety by preventing errant vehicles from sliding out of the roads and impacting the roadside buildings or other objects. So it is most commonly fixed on the side of the highways, dock areas, aisles, especially on curves and slopes for protection against run-off-road collisions.
Our W-beam guardrail product is formed in accordance with the latest highway safety barrier technology for making sure its high durability and maximum strength. It is made of high quality steel, which reduces the impact force caused by mobile equipment to the maximum extent.
Meanwhile, the zinc coating or PVC coating perfectly combined to the W-beam guardrail keeps the products free of damages of corrosion and rust.

FAQ
1. How Does RAMSHIELD Function?
RAMSHIELD w-beam guardrail safety barrier achieves a controlled redirection of errant vehicles by releasing the w-beam guardrail from the post at an optimal load to retain rail height, limit dynamic deflection and to allow the post to collapse without tripping the vehicle.
The separation of the w-beam guardrail from the post is achieved by a release tab incorporated into the post. The tab is designed to pull forward and tear from the post and remains connected to the rail to ensure there is no debris from the system that may otherwise present as a danger to other motorists.
RAMSHIELD uses standard state road specified w-beam guardrail and standard fasteners meaning there is very little risk of inadvertent use of non-compliant items.
2. How Does The Performance of RAMSHIELD Compare With Australian State Road Agency Design?
RAMSHIELD w-beam guardrail safety barrier has been fully crash tested and evaluated according to the specifications for Test Level 3 (TL3) of the AASHTO Manual for Assessing Safety Hardware (MASH). The MASH specification is an update to and supersedes NCHRP Report 350 for the purposes of evaluating new safety hardware devices.
MASH is also the basis of testing procedures for road safety systems as stated in AS/NZS 3845.1: 2015 Road Safety Barrier System and Devices. Australian state road agency w-beam guardrail designs do not meet the MASH performance level.
3. What Crash Test Impacts Have Been Performed With RAMSHIELD?
RAMSHIELD w-beam guardrail safety barrier has been crash tested as follows;
2270kg pick-up truck travelling at 100km/h and 25 degrees. Recorded impact energy of 156kJ.
1700kg passenger car travelling at 110km/h and 25 degrees. Recorded impact energy of 142kJ.
1100kg passenger car travelling at 100km/h and 25 degrees. Recorded impact energy of 83kJ.
Two (2) impacts were performed with the 1100kg passenger car, which included a reverse direction impact.
