Vehicle crash barrier

Guardrail for road sides of the ground (Grades 2W SB2 and SB4(Left) / Grades 3W SB2,SB3-B,SB5-B, and SB4 (Right))

Prevents accidents in advance by preventing vehicles from going to the shoulder of expressways, routes, or general roads and people from passing.

Open-type guardrail (Grades SB2 and SB4)

Is much more visible than the surrounding landscape and prevents vehicles from running off the tracks because of more excellent performance than the existing general (W type) guardrails.

Median strip (Standard Grades 2W and 3W SB4 (Left) / Narrow width Grade 3W SB4 (Right)))

Is installed to prevent accidents due to vibration of the centerline in advance by smoothing the flow of traffic in both directions of expressways and routes with more than four lanes, motorways, and sections with poor load alignment.

Transition section (Grade SB4)

It’s the section of connecting more than two crash barriers with different types of strength to one another and prevents the second accidents due to being overturned and spinning by preventing vehicles from pushing and entering them in case of colliding with them.

End treatment facilities (ET2)

In case that vehicles collide with the end, there is a strong possibility that member of crash barriers penetrate into the inside of the vehicles and seriously threatens the occupants’ safety, while the end treatment facilities (ET2) has a function to make the vehicles which run off the tracks stop safely or return to the direction by absorbing their impact energy.

Median strip (Standard Grades 2W and 3W SB4 (Left) / Narrow width Grade 3W SB4 (Right)))

Is installed to prevent the second accidents and secure occupants’ safety because of making the vehicles which run off the tracks or collide with each other return to their direction safely or reduce their speed by absorbing their impact energy with their rotational energy.

Guard fences for bridge rails

Prevents vehicles from falling in advance by being installed on overpasses, bridges for crossing the sea and the rivers.

Assistant post construction method for reinforcing bearing power

01. Test for reinforcing bearing power (Before the test)
02. Test for reinforcing bearing power (After the test)

It’s the construction method that brackets are connected to the back of the existing guardrail supports with them, piling work is done on underground anchors (Two left and right places) with a pilling rod, and the cross section of the pipe which was cut in advance penetrates into ground being bent and widely spreads so that the pullout force of the anchors increases bearing power.

Assistant post construction method for reinforcing bearing power[BRACING TYPE]

01. Test for reinforcing bearing power (Before the test)
02. Test for reinforcing bearing power (After the test)
03. Bracing Type

It’s the method to install auxiliary supports with the certain depth in four sides of a guardrail support and connect them to the main support with connecting materials. The method uses the principle that the lower loading position to act on the support is, the higher resistance of the support and ground is. Bearing power of the support increases as the maximum load that the auxiliary support can bear acts on the main support as the reaction force. At this moment, the load is delivered through strut. The auxiliary support is installed to be separated from the ground range which is destroyed by the main support.

Movable temporary crash barrier (Left) Concrete / (Right) Iron

단부처리시설(ET2)

Feature Feature Absorbs impact being bent when vehicles collide with it. Is simple and easy to be connected, assembled, and installed and can freely be moved and disassembled.
Range of application Is installed on sections for inducing vehicles in construction sites, preventing jaywalking and illegal U-turns, and protecting vehicles temporarily.

※ A plan for improving traffic safety facilities in road construction sites by The Ministry of Land, Infrastructure and Transport, the Wonju Regional Construction and Management Administration
Making the installation of temporary fences [Crash barriers] with protection performance when vehicles collide with them on their tracks compulsory to protect buzzers, workers, occupants, and human life in the construction sites. December 18)
