Specific parameters of galvanized corrugated guardrail

Specification classification:

Double wave corrugated guardrail board: 4320mm×310mm×85mm×3mm/4mm

Three-wave corrugated guardrail board: 4320mm×506mm×85mm×3mm/4mm

Double wave corrugated guardrail column: 114mm/140mm×4.5mm×height;

Three-wave corrugated guardrail column: 114mm/140mm×4.5mm×height;

Column spacing: divided into 2-meter spacing and 4-meter spacing;

Connection method: There are two ways of connecting the column and the board: anti-block type (matched with nine-hole plate) and bracket type (ten-hole plate).

Usage: The standard section of the corrugated guardrail board has a column spacing of 4 meters per kilometer, using 250 boards, 250 columns, 2 ends, 250 column caps, 250 anti-blocking blocks, 250 sets of connecting bolts M16×170/42, and splicing bolts M16×35 2000 sets.

Material: Q235

Surface treatment of corrugated guardrail: hot dip galvanizing, cold galvanizing + plastic spraying, hot dip galvanizing + plastic spraying.

Principle of wave guardrail: When external force is applied, the guardrail panels and columns deform to absorb the impact force and protect pedestrians and vehicles.

Application of corrugated guardrail: Currently widely used in domestic highways, first- and second-class highways, provincial roads, county roads, scenic spots, rural roads, etc.

The functions of wave guardrail: safety protection and beautifying the environment.

The most commonly used model of corrugated guardrail: Gr-A-4E. The amount of Gr-A-4E guardrail components per 1000 meters is: 250 corrugated plates. 250 columns. 250 column caps. 250 anti-blocking blocks (or brackets). Bolt M16*170, 250 sets. M16*42,250 sets. M16*35, 2000 sets.

Advantages of galvanized corrugated guardrail panels:

1. After galvanized surface treatment, the corrosion resistance of the guardrail board is increased and the service life of the guardrail board is increased.

2. Low price and good quality. #3 guardrail board is made of high-quality and low-carbon Q235 material. Zhongan's large-scale production has achieved the ideal goal of low cost and low charges, and can provide users with a low price. Moreover, the quality standards of #3 guardrail panels meet the standards of the construction inspection department.

3. Installation services. When purchasing #3 corrugated guardrail panels, installation services will be provided. Zhongan is an enterprise integrating production, sales and installation.

The function of corrugated guardrail board

Corrugated beam guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail panels spliced to each other and supported by main columns. It uses the deformation of the soil foundation, columns and beams to absorb collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction, preventing the vehicle from running off the road to protect the vehicle and passengers and reduce losses caused by accidents. The corrugated beam guardrail is both steel and soft, with strong ability to absorb collision energy and anti-collision. It has a good line of sight induction function, can be coordinated with the road alignment, has a beautiful and coordinated appearance, and can be used on small radius curves. Easy to replace. Combined corrugated beam guardrails are available on narrow center dividers. For sections where vehicles may cross the road (bridge) and cause serious consequences, you can choose to strengthen the corrugated beam guardrails.
