Metal beam guardrail is semi-rigid w or thrie profile galvanized barrier. Metal beam guardrail is the most common roadside rail in use in most countries in the world. Tongsu traffic supplies various standard types of metal beam guardrail in two waves w rail and three waves thrie beam, effective lengths in 3.2m, 3.81m, 4.0m.
Features
Metal beam guardrail is cold roll formed from steel coil and cut to standard lengths. It is then punched, slotted and hot dip galvanized in accordance with AASHTO M180 and client's specifications.
For instance, our metal beam guardrail is available on stock in standard effective lengths 3.20 meters for U.A.E and 3.81 meters for Saudi, Oman, Qatar and 4.0 meters for African and eastern Asian countries such as Mauritius, Kenya, Malaysia, Indonesia, Brunei, Philippines, etc. We also customize longer rails for some American countries such as Brazil, etc.
Metal beam guardrail conform to the designation of AASHTO M180 and AS/NZS 3845 Road safety barrier systems. Factory checked and third party inspected for use by SGS, Intertek, TUV, etc. Specifications differ between nations,
The metal beam guardrail system is the most commonly used road safety barrier system worldwide. The main reason for its widely application is that it consists of a rigid post and a flexible and energy absorbing spacer block design, which has been approved by crash test as being highly effective in reducing snagging and preventing vehicles from crossing over the rail.
Tests show that in automobile accident, the impact power is greatly absorbed by the deformation of the posts and blocking piece. At the time the w rail and posts separate, the w rail provides a re-directive function, guiding the vehicle back to traffic flow and avoid the chance of the vehicle crossing over the rail.
Tongsu Traffic produce and supply metal beam guardrail system and accessories worldwide. Well known for their trustworthy and professionalism, our experienced salesman will always provide expert response and we have completed countless projects for home and abroad.
Our metal beam guardrail system has been fabricated in maximum conformity with AASHTO M180 and relevant international standard designation and you are rest assured.
Never save money when it is involving people and road safety, your safety our job!
