thrie beam guardrail design of road

thrie beam guardrail design of road introduce

thrie beam guardrail design of road is a kind of guardrail for road collision avoidance. It is the main form of semi-steel guardrail.thrie beam guardrail design of road is also a continuous structure in which corrugated steel guardrails are spliced ​​to each other and supported by the main column.

thrie beam guardrail design of road are classified according to the location and collision level. According to the setting location, it can be divided into road side guardrail and central middle partition guardrail. According to the anti-collision level, thrie beam guardrail design of road can be divided into A level and S level.

The S-class guardrail is of a reinforced type, which is suitable for use on road sections where thrie beam guardrail design of road is particularly dangerous, and Class A is used for special roads. Fence sheet material: high-quality steel plate after anti-corrosion treatment High-speed guardrail board manufacturing process.

steel wire after welding, can also be electroplated, hot-plated and plastic coated. Use of guardrails: Fences, decorations, and defenses for industries such as industry, agriculture, urban management, and transportation.

The guardrail board products are unique and special: anti-corrosion performance, anti-aging, good-looking and generous. The installation is simple and convenient. Raw material: national standard q235, low carbon steel plate, etc.

Application of highway guardrail

Surface treatment: Dip molding after extrusion; can also be electroformed or zinc-plated after hot stamping of zinc-plated hot-dip galvanized steel; low-carbon steel blackboard after extrusion molding; galvanized after low carbon steel blackboard extrusion molding Dip/spray; dip material is (pvc or pe); Scope of application:

Safe collision avoidance of highways, large parking lots, etc. Product-specific and special places: Bending increases the visibility and increases the mesh Strength, both; the automatic production line is extruded, the surface is clean and damage-free, and the corrosion resistance is very strong;

thrie beam guardrail design of roadthe surface treatment is mature; the pe&pvc material is non-toxic and harmless, anti-corrosion, anti-aging, anti-sun, high-resistance, Unique places such as low temperature.

thrie beam guardrail design of road development

the use of life in the outdoor environment can reach 10-20 years; the product structure is brief, good-looking and practical, easy to transport, install, good anti-theft performance, limited by actual terrain, for mountains.

highway guardrail weight

thrie beam guardrail design of road broken fields The multi-bend area has strong conformity and moderate cost.The guardrail board is currently galvanized and plastic coated. The galvanized layer has lower hardness and is more susceptible to mechanical damage than ordinary steel.

Therefore, be careful during thrie beam guardrail design of road construction, and gently handle it. After the galvanized layer is damaged, Apply with high concentration of zinc within 24 hours and replace if necessary. When installing, first install the bracket on the column, do not tighten the fixing bolt too tightly,

then fix the guardrail on the bracket with the connecting bolt, and splicing the guardrail with the splicing bolts, if the splicing is reversed, even if thrie beam guardrail design of road is slight The collision will also cause a large loss.

The anti-collision guardrail should be constantly adjusted during the installation process. Therefore, the connecting bolts and the splice bolts should not be tightened too early.

The long round holes on the guardrail should be used to adjust the line shape in time to make the line shape smooth and avoid local unevenness. The top line of the guardrail is considered to be linear. When you are satisfied, tighten all the bolts. According to the experience,

highway guardrail

thrie beam guardrail design of road the installation of the guardrail board is the most qualified for the group of 3, 5, and 7 people. It is easier to install when the installation direction is opposite to the driving direction.
