steel guardrail beam-manufacture,factory,supplier from China

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.

Raw material prices: The main raw materials for guardrail beam is metal materials such as steel, aluminum, stainless steel, etc. The price fluctuations of these materials will directly affect the price of guardrail beam. The fluctuation of raw material prices is often influenced by various factors, such as market supply and demand, trade policies, natural disasters, etc.Technical difficulty: The production difficulty of different types of guardrail beam varies, and complex design and processing techniques can increase manufacturing costs, leading to an increase in the price of guardrail beam.

1. Guardrail beam: This is the main component of guardrail beam, usually made of hot-rolled steel. Its specifications are usually 220 * 150 * 100, and there are also some special specifications of guardrail beam.2. Column: Column is the supporting structure of guardrail beam, usually made of hot-rolled steel. Its specifications are usually 250 * 120 * 100, and there are also some special specifications of columns.3. Cross beam: A cross beam is the transverse support structure of a guardrail beam, usually made of hot-rolled steel.

1. The guardrail beam is made of low-carbon steel, which has good elasticity and strong collision absorption ability. After surface rust removal, acid washing and other chemical processes, hot-dip galvanizing is carried out to improve the aesthetic effect of anti-corrosion design. Except for the splice bolt M16-35 which is made of 45 steel, the rest are made of Q235.2. The appearance of the guardrail beam is smooth, with a smooth surface, bright colors, and elegant appearance.

Firstly, the price of guardrail beam mainly depends on their production cost. This includes the cost of raw materials, processing costs, as well as transportation and storage expenses. Among them, the cost of raw materials accounts for the main part of the price of guardrail boards. Generally speaking, the material used for guardrail beam is mainly steel, so the price fluctuations of steel will directly affect the cost of guardrail beam.Secondly, processing costs are also an important component of the price of guardrail beam.

1. The guardrail beam is the main form of semi-rigid guardrail. It is a continuous structure composed of corrugated steel guardrail beam that are spliced together and supported by columns. It uses the deformation of soil foundation, columns, and guardrail beam to absorb collision energy, force out of control vehicles to change direction, return to normal driving direction, prevent vehicles from rushing out of the road, protect vehicles and passengers, and reduce losses caused by accidents.2.

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.

1. The guardrail beam  is located in the middle of road development, which can effectively prevent the occurrence of a second utilization collision when a vehicle loses control and runs into the opposite lane.2. Guardrail beam is a semi steel protective device with good toughness, which forces the vehicle to return to the normal route when it collides.3. Guardrail beam can effectively alleviate the harm that collisions can cause to drivers. Guardrail beam have good toughness and are not easy to break.

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.

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.
