Terminal End Section and The Buffer end for highway guardrail

The end of the highway guardrail is the end of the road guardrail or joint part, which is composed of an end, because the road conditions are different, so the road guardrail end is divided into a variety of styles, according to the guardrail design situation, the guardrail end is generally divided into the following types: Fishtail End, Buffer End, Round End(bull-nose end), Ground anchor end, Bridge End, Extruded guardrail end, etc.

The roadway guardrail terminal end are installed at the end of each part of crash barrier system with the aim to prevent damage and harm to pedestrians and vehicles when vehicles become errant and crash at the end of guardrails. Generally speaking, every 1000 meters will need two pieces of guardrail end terminals.Rounded guardrail end, known as the bull-nose end, this kind of guardrail end looks like a "?", generally used at the end of the road, play the role of guidance and impact prevention, it is made of strip steel stamping, after hot dip galvanized or hot spray treatment, the surface corrosion resistance is strong, as the end of the fish tail, installation is simple, construction is convenient.The bull-nose end is widely used because it is easy to manufacture and install, and has better guiding function in the case of small collision Angle.Double Terminal End, also known as Buffer End, are mounted on road bends or median strips.

1. Fishtail End,

2. Buffer End,

3. Round End (bull-nose end),

4. Ground anchor end,

5. Bridge End,

6. Extruded guardrail end, etc.
The fishtail end, is a European and American countries design concept, it is shaped like a fish's tail, so it is called the fishtail end, it can also be called an end-wing. It consists of the strip which is formed after punching and forming a molding. This product is simple and easy to assemble, and through the surface hot galvanizing processing it undergoes it as gained a strong anti-corrosion ability, it can play a guiding role to the cars on the road, it reduces the effect of collisions and it effectively prevents the vehicle from leaving the road.
The fishtail end is divided into two types of specifications and models with W beam and Thrie beam. W beams are used with a W beam guardrail plate, and Thrie beams are used with a Thrie beam guardrail plate.

Guide-able road guardrail crash mat

An anti-collision pad is another name for an anti-collision block, buffer pad, rubber block, etc.The cushion is mainly installed at the edge of the loading and unloading platform, which facilitates the parking of trucks and reduces the difficulty of parking for drivers. It plays a role in protecting the platform, loading and unloading equipment of the platform and trucks from damage.
Anti-collision adhesive is one of the necessary protective devices for unloading platform. Craps made of material and process rubber are usually applied to the entire front edge of the cargo platform, while craps made of natural rubber (the same material as automobile tires) are usually used to fix both sides of the loading and unloading position equipment.
Anti-collision cushion is a device that can stop the vehicle safely and change the driving direction of the vehicle to avoid serious injuries to passengers by absorbing the collision energy of the vehicle. Its main function is to reduce the severity of the accident. On the other hand, it also plays a warning and inducing role through its surface color and graphic symbols.

There are many kinds of anti-collision pads, which can be divided into kinetic energy principle and momentum conservation principle according to the anti-collision principle. Kinetic energy principle Collision cushion absorbs the kinetic energy of the vehicle by cushioning or absorbing energy through the destructible or plastic deformed material or structure set in front of the collision object. This structure needs rigid support or obstruction to make the energy absorbing material or structure deform to reduce the impact force on the vehicle.
According to the law of momentum conservation, the other is a structure that transfers the momentum of the runaway vehicle through some sand and water containers set in front of the anti-collision object and plays a buffering role.
This kind of structure has strong flexibility in construction and is more convenient in application.

The structure of the cushion Kinetic energy principle anti-collision pad is generally composed of the end, energy absorbing material, both sides of the beam, diaphragm and back support. After a vehicle collides with the anti-collision pad, it absorbs the energy of the colliding vehicle through the deformation of the end part and energy absorbing material, and the back support is used to resist the impact force of the vehicle.
Energy absorbing material is generally foam material or rubber material, the principle of the anti-collision pad for the front and side of the vehicle has a good effect of energy absorption and guidance, and the system after the collision, the main components can be reused, convenient and fast maintenance and low cost, the disadvantage is a little more complex and high cost of the initial installation.
