Ground anchor end (bend-ed end) is a new type of end of road guardrail

The end of the highway waveform guardrail plate is used in the round head type or ground anchor type, the ground anchor guardrail is at the end of the road guardrail, will our guardrail bending, side and road guardrail connected, the other side through this Angle, buried in the earth, at the beginning or end of the road play a guiding or extension role. If the out-of-control vehicle hits the front of the end, there is a possibility that the guardrail may penetrate the car. Therefore, ground anchor type end treatment can be adopted according to the needs of the road section. This end treatment uses the inclined Angle of waveform beam to gradually extend to the ground, and is directly anchored underground with concrete foundation at the end, without the need for additional end beam installation. In the frontal collision of the runaway vehicle, the vehicle will climb up along the diagonal waveform beam and absorb energy. When side impact, it also has better guiding function. The purpose of setting the end of the corrugated guardrail is to eliminate the potential safety hazard of the end. According to the survey, the vast majority of the hazards are caused by the insertion of wavy guardrail boards into cars. First of all, to eliminate the hidden danger is to avoid the waveform guardrail plate inserted into the car, the vehicle and the human body caused injury; Secondly, the use of clever design, so that the waveform guardrail plate end in the impact of energy absorption, reduce the speed of the vehicle, and reduce injuries. Under the premise of achieving the above two requirements, we should also ensure the basic function of the waveform guardrail plate, that is, prevent vehicles from rushing out of the lane, to ensure the safety of vehicles.

Guardrail Blocker refers to a prevention block, blocker ,block-out. In some places, it is known as a “Spacer” or a “Separator”. It refers to the part between guardrail and post,and with many different shapes or designs. The block itself is an energy absorbing part,so it could make the guardrail deform gradually during the sudden collisions. This is conducive to energy absorption, it helps reduce occupant casualties; at the same time, the block could allocate the crash energy to the guardrail and post, thereby increasing the overall strength and tension of the guardrail system.The guardrail block is installed between the guardrail and the post with the function of energy absorbing. If there is no block, vehicles are forced to stop through the deformation of the guardrail, the post and the roadbed.

The Channel type block is made of steel, which is directly truncated and perforated. The production process is simple and the cost
is low, and it is mainly used in developed countries such as Europe. This high-speed guardrail structure has strong bearing
capacity and strong strength, which can effectively prevent vehicles from rushing out after collision and avoid secondary
accidents. The Channel shaped block is mainly respectively used in conjunction with the Channel shaped post, which is connected
with the guardrail plate on one side and the post on the other side to play a bonding role. The whole block is assembled into the
highway guardrail to effectively prevent vehicles from deviating from the road. Channel type highway guardrail components
generally undergo a hot-dip galvanized treatment, anti-corrosion, enhance the life span of guardrail.

Galvanized Channel Spacers for Guardrail:
1 .Material: steel: Q235 (S235JR / ASTM A283M) or Q345 (S355JR / ASTM A529M 1994)
2. Standard specification: 150*100*4.3/5.5 or 120*55*7.0/9.0mm
3. Surface Treatment: Hot dipped galvanized or powder coated
4. Zinc coating thickness (double sides): 550 g/m2 (40µ) / 1100 g/m2 (80µ) / 1200 g/m2 (85µ)
5. Relevant parts required for guard rails: post, spacer (C, U and Sigma types etc) ,end and fasteners
6. Other special specification as per client's requirement or drawings.

Advantages:

1. Highway and bridge safety.
2. Great corrosion resistance and good impact resistance.
3. Samples available for you to check the quality.
4. Connects the ten hole corrugated plate and the post.
5. Good energy absorption effect.
6. Protects the safety of vehicles and passengers.
7. Helps increase the overall strength of the fence.

The box-shaped anti-blocking block, has a similar appearance to a box, this is achieved by steel belt punching formed after welding. After it is hot dip galvanized, it's surface is clean, has anti-corrosion, and it has a trapezoidal shaped surface. After the blocker has undergone all the processes it now has strong bearing capacity, impact resistance, it can resist the collision of out-of-control vehicles, and it can effectively prevent vehicles or pedestrians from going out of the road. The box block is usually used in combination with the C-shaped post to support the guardrail. One end of the box is connected to the C-shaped post and the other end is connected to the guardrail plate to act as a bond.

The most common type of highway guardrail connection is the bracket

W beam guardrail bracket, a continuous structure with corrugated steel baffles joined together and supported by a main post. It is generally known as the bridge bracket or dovetail-shaped bracket, bracket material for Q235 cold rolled strip steel, stamping formed surface to do anti-corrosion treatment, surface treatment: Hot dip galvanized (silver white), galvanized + plastic sprayed (blue, white, green, yellow). The bracket is used to connect the ten-hole corrugated plate and the column, and absorb a large part of the impact force through its own deformation when impacted by external forces. Good energy absorption effect to protect the safety of accident vehicles and personnel. The advantage of brackets is low processing cost. Small size, easy to transport. Installation is simple and easy to operate.

W beam guardrail accessories cross partition beam for the road central separation belt with a column double - hanging guardrail.

It is used in the middle of the road to separate the guardrail of one-way roadway. The two ends are connected with the guardrail of two-way road respectively, and the middle is connected with the column to serve as a link between the above and the below.
