Highway crash barrier

1 Scope

The highway anti-collision guardrail is also called “wave beam guardrail” and “corrugated board”. The highway anti-collision guardrail is a typical cold-formed corrugated plate or Q235 carbon steel pipe as the substrate. The hot-dip galvanizing process is firstly carried out, and then the flow-dipping process is used to uniformly coat the inner and outer surfaces of the hot-dip galvanizing layer. Ethylene powder, which can enhance the anti-collision protection and greatly improve the anti-corrosion and anti-corrosion ability of a composite product.

2, the composition

2.1. The highway anti-collision guardrail is composed of corrugated beam plates, columns, ends, fasteners, anti-blocks, brackets and other components.

2.2, coating: special coating for polyethylene.

3, classification

Highway anti-collision guardrails can be divided into standard type and adjustable type according to their standards; standard type refers to standard length boards used in installation. An adjustment plate is a plate that is handled by a dispensing method to handle non-standard spacing.

4, specifications

4.1. Specifications of corrugated beam plate (plate length × plate width × wave height × plate thickness)

The standard type has a length of 4320×310×85×3mm;

The length of the adjustment type is 3820×310×85×3 mm;

3320×310×85×3mm;

2820 × 310 × 85 × 3mm.

4.2. The column is a steel pipe column, and its specifications are ¢114×4.5mm and ¢140×4.5mm.

4.3. Both the end anchor type and the round head type, the specifications are R-160, R-250, R-350mm.

4.4. Fastener splicing bolt M16×45mm, washer ¢35×4mm, gasket 76×44×4mm, etc.

4.5. The specification of the anti-blocking block is 178×200×3mm (used in conjunction with the ¢114 steel pipe column).

4.6. The specification of the bracket is 300×70×4.5mm R=57mm.

5, characteristics

As a basic safety facility on the highway, the crash barrier plays an important role in promoting traffic safety on our high-grade roads. The crash barrier acts as an integral part of the safety facility and plays an important role in preventing traffic accidents.

The product is called a hot-dip galvanized polyethylene dip steel fence. It has strong mechanical strength, strong adhesion, good corrosion resistance, good weather resistance, anti-aging performance, acid and alkali resistance, low temperature and no brittleness, wide temperature range (-40°-80°), impact resistance Strong ability, not only can guarantee the function of anti-collision, but also improve the service life of the product. At the same time, beautify the environment, it is the most ideal ring protection bar product in highway engineering construction.
