Questions You Should Know about Hot Dip Galvanized W-Beam Guardrail

W beam guardrail, corrugated guardrail, high-speed anti-collision strip, bridge guardrail, etc., commonly known as wave-shaped guardrails, can be divided into two-wave and three-wave guardrails.

W beam guardrail consists of two corrugated steel guardrail panels and two columns sandwiched between them. The two columns sandwich the two corrugated steel guardrail panels in between. When a vehicle collides with it, the corrugated steel beam guardrail panel has good anti-collision and energy absorption properties, is not easy to be destroyed, and can protect the vehicle and passengers.

What are the precautions for cutting w beam guardrail?

• The basic requirements for guard rail in highway: The railings and guardrails must not be broken or bent. After the sidewalk board is laid, the railing components must be installed. except for couplings, the filled guard rail in highway and handrails must be smooth, and must be constructed. Effective telescopic bare steel guardrails should be protected in accordance with design requirements, whether it is balcony guardrails, guard rail in highway, or wrought iron guardrails. For the installation of W beam guardrail, the ultimate goal is to protect life safety through guard rail in highway and prevent serious consequences. Regardless of the type of wave guardrail, the most important performance is safety.

• The next step is to consider the impact of drivers' aesthetic psychology on guard rail in highway, increase the comfort and safety of road users through the installation of guardrails, naturally attract drivers' attention, maintain the continuity of highways, and reduce the fear caused by dangerous intersections.

• To achieve the above objectives, the performance requirements of W beam guardrail are as follows: the requirements of the vehicle's self-adaptive structure, no cutting or excessive protection, to prevent damage caused by the car's driving method or collision with the opposite lane highway guardrail, making the vehicle's driving direction change, preventing the aft collision of the cabin or other traffic dangerous rear collision of the guardrail component. This is the strength requirement of W beam guardrail. The rear passenger risk requirements and the collision acceleration of the collision vehicle should remain upright, without injury. The highway guardrail should produce a certain amount of elasticity and plastic deformation to absorb collision energy, reduce damage to the vehicle, and prolong the collision process to ensure the safety of passengers in the car. The vehicle's trajectory requires the vehicle to collide with the waveform. After the guardrail, the vehicle returns to its original departure direction with a smaller departure angle, and the vehicle's trajectory and final parking position do not affect the driving of other lanes. Each kind of wave guardrail has its own characteristics and application conditions.

What should be paid attention to when installing w beam guardrail? What are the benefits of using w beam guardrail panels?

• The preparation for installing w beam guardrail should be sufficient, and the stake position on the construction section should be accurate. The layout should be precise, with errors within a specified range.

• The construction of W-beam guardrail columns should be strictly and carefully carried out, with verticality, spacing, bolt hole position, and other dimensions strictly controlled.

• The production and installation of W beam guardrail panels should meet the requirements. If they do not meet the requirements, they need to be reworked immediately. At the same time, they should be strictly reworked according to the specifications stipulated in JTJ074-94.

• The packaging and labeling of components such as W beam guardrail panels and columns should comply with the requirements of GB. The guardrail should not be loose during purchase, and it should be ensured that it does not deform or damage (injury) during lifting, transportation, and stacking. During transportation, it should be securely fixed to prevent damage to the coating or deformation of the components due to bumps and collisions.

• During the w beam guardrail installation, care should be taken not to damage facilities such as cables and pipes buried under the road surface.

1. Introduction of W beam guardrail

People pay more and more attention to the importance of W beam guardrail. W beam guardrail is a combined, corrugated and movable steel guardrail at the opening of the central separation belt of the highway. The guardrail is composed of two corrugated steel guardrail plates and two upright posts fixedly sandwiched between them.

2. The role of W beam guardrail

In economically developed areas, the villages and towns along the highway are relatively dense, and there are many passages crossing the main line, which means that the height of embankment should be increased and the danger of highway slope will increase. Besides the high embankment height and steep slope, the width of central partition, kerb and shoulder is also short, which requires the setting of highway metal guardrails.

W beam guardrail installation can not only prevent runaway vehicles from rushing out of roads and off-road obstacles, but also prevent other objects from rushing into lanes through the central partition to cause more traffic accidents. It can also restore the normal driving direction of vehicles, minimize the damage to passengers and induce the sight.

3. Design conditions of W beam guardrail

W beam guardrail is generally divided into flexible guardrail, semi-rigid guardrail and rigid guardrail. It has certian flexibility and can absorb collision energy and avoid collision through the deformation of the beam. In addition, it has a good line-of-sight induction function, which can be coordinated with road alignment. It can be used in small radius bends with beautiful and harmonious appearance. The damaged parts are easy to replace.
