steel bridge guardrail-manufacture,factory,supplier from China

During the construction process of highway guardrail, it is important to accurately grasp various facilities. Firstly, the accurate positions of various pipelines buried in the roadbed should be ensured that they do not cause any damage to underground facilities during the work process.2. Column layout: Column layout shall be carried out according to the design drawings, and distance measurement system positioning shall be carried out using highway guardrail as control points for a bridge, passage, culvert, divider opening, overpass, level crossing, etc.3.

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.

The highway guardrail board 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.

The highway guardrail is composed of two corrugated steel guardrail panels and two fixed columns clamped between them. The two columns are fixed and clamped between the two corrugated steel guardrail . During normal operation of highways, highway guardrail can be easily inserted into the pre-set insertion holes at the openings using plug-in columns, providing isolation and protection.

The highway guardrail is a continuous structure, mainly composed of corrugated steel guardrail boards. Each two corrugated steel highway guardrail is fixed on the highway guardrail columns by splicing to form a whole. This structure composed of corrugated guardrail plates not only has a beautiful appearance, but also is convenient to use. For example, simply inserting the column into the corrugated guardrail plate can play a good isolation role, which is convenient and fast. So why do highway guardrail uses corrugated guardrails among numerous guardrails?

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.

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. 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.

The most common materials used in highway guardrail processing are steel, aluminum alloy, and galvanized steel plate.Steel plays an important role in the manufacturing of highway guardrail due to its high strength and durability. It can effectively prevent vehicle collisions and has good anti-corrosion performance, which can extend the service life of guardrails.Aluminum alloy is another common material that is highly favored due to its lightweight, high strength, and excellent corrosion resistance.

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.
