highway guard rail beam-manufacture,factory,supplier from China

The guardrail beam in the highway guardrail is its main component, playing a crucial protective role. The guardrail beam is usually composed of soil foundations, pillars, beams, and endurance boards, which work together to absorb collision energy and guide out of control vehicles to change direction, preventing them from rushing out of the road.Structurally, the waveform steel plates of the guardrail beam are spliced together and supported by pillars, forming a continuous structure.

Basic requirements for highway guardrail: Wave beam and rigid guardrail products should comply with relevant document standards such as "Highway Wave Beam Rigid Guardrail" and "Three Road Beam Guardrail". The installation of guardrail columns, corrugated steel, anti blocking blocks, and brackets should meet the requirements of design and construction. To ensure the overall strength of highway guardrail, the compactness of the shoulder and central divider should not be lower than the design value.

(1) The corrugated guardrail beam should not have obvious torsion, nor should it be welded or lengthened, and the end burrs must be removed. The layout of columns is based on the control points on the highway, and the spacing between columns is adjusted appropriately according to the measurement distance; The installation of columns should be consistent with the design drawings and coordinated with the road alignment.

1. Strictly implement the inspection system for guardrail beam components. The construction unit shall report to the supervising unit (group) the acceptance status of the guardrail beam structural accessories entering the site, provide factory certificates, and conduct testing in accordance with the requirements of the current highway engineering quality evaluation standards before installation. After passing the acceptance inspection.2. Strictly adhere to the form, quantity, and location of safety items designed in the approved construction drawings.

The reflection problem of guardrail beam is also a particularly important issue in daily inspection. Guardrail beam that have lost their reflection effect cannot provide drivers with correct direction guidance at night, so reflection inspection is also important to pay attention to!The waveform guardrail beam installed on both sides of the highway are inevitably scratched and collided by some vehicles, resulting in the loss of their previous collision resistance and protective effect. Therefore, we need to stop regular maintenance on them.

Guardrail beam not only has the advantages of good impact resistance, low cost, long service life, and higher safety, but the beautiful design is also coordinated with the highway environment, improving the overall aesthetics of the road.In recent years, with the improvement of road safety awareness and vehicle speed, the design and construction requirements for guardrail beam has also been constantly increasing.In addition, the reuse of guardrail beam has also become a focus of attention.

The guardrail beam is mainly used for isolation and protection of highway lanes. The utility model relates to a combined type corrugated plate movable steel guardrail used at the opening of the central dividing strip of the highway. The guardrail is composed of two corrugated steel guardrail boards and two columns fixed and clamped between them, and the two columns are fixed and clamped between the two corrugated steel guardrail boards.

1. Ordinary w guardrail beamThe ordinary corrugated guardrail is the most basic corrugated guardrail, which is made up of multiple W-shaped steel plates and is shaped into a wave shape. This guardrail has the advantages of easy installation and low cost, and is widely used on both sides of highways. However, its protective performance is relatively poor and is not suitable for highways with fast speeds.2. Highway guardrail beamThe highway guardrail beam is improved on the basis of the ordinary corrugated guardrail.

Firstly, guardrail beam should have sufficient strength and stiffness to withstand the impact force of vehicle collisions, prevent vehicles from crossing or collapsing through guardrail beam and thus avoid the occurrence of secondary accidents.Secondly, guardrail beam should have good energy absorption performance, which can absorb the kinetic energy of vehicle collisions and reduce injuries to vehicles and passengers.In addition, guardrail beam should also have good line of sight guidance function, which can coordinate with the road alignment, provide clear driving direction indications, and

1.Regular dust removal: Due to the accumulation of outdoor dust, the surface of the guardrail beam may be covered with a layer of floating dust, which not only affects the glossiness of the guardrail beam, but also may cause corrosion, rusting, and cracking of the protective film.
