highway guardrail history

highway guardrail history

The highway guardrail use the deformation of the soil foundation, post and beam to absorb the collision energy, and force the out of control vehicle to change direction, restore to the normal direction of driving, prevent vehicles from out of the road, to protect vehicles and passengers, reduce the loss caused by the accident.

First generation of highway guardrail history：

hot dip galvanized highway guardrail

Advantages: good self repairing effect and strong UV resistance。

Disadvantages: hot dip galvanizing is acid cleaning and low temperature heating, which is heavy purification and high energy consumption. Without acid, alkali, salt, cold and fear of rotten land, the earth will soon be fast.

The second generation of highway guardrail history:

Hot-dip galvanizing + electrostatic spraying steel guardrail

Advantages: UV, acid, salt, dry and cold rot.

Disadvantages: hot dip galvanizing is acid cleaning and low temperature heating, which is heavy purification and high energy consumption. Thin coating is afraid of bumping. Vertical columns inside the walls do not sprout quickly in the soil.。

The third generation of highway guardrail history：

Hot-dip galvanized + polyethylene dipped plastic guardrail

Advantages: coating thickness, life progress 1~2 times. Anti ultraviolet, acid, alkali, salt, cold and impact resistance have good protective effect in soil.

Disadvantages: hot dip galvanizing is acid cleaning and low temperature heating. It belongs to heavy purification and high energy consumption.。

Disadvantages: hot galvanizing is acid washing and low temperature heating. It belongs to the heavy purification and high energy consumption.

Hot dip galvanizing has the characteristics of pickling and low temperature heating. It belongs to the industry of high purification and high energy consumption.

Traditional working methods, such as breaking strength, rest, low productivity and uneven product quality, can not achieve standardized production.

The function of the highway guardrail history is poor and the application period is short；

Fourth, after the corruption of the Protection Bureau, the disposal can only be abolished, and no recycling can be applied:

Epoxy zinc based polyester coating guardrail

High safety, energy saving, environmental protection, long term, repeated application。

Classification of highway guardrail

Traffic facilities are ubiquitous in our daily life, such as traffic lights, deceleration strips, block blocks, guardrails and so on. They are what we often see and even be accustomed to negligence, these are to ensure the safety of pedestrians, the normal operation of the auxiliary equipment, so we should abide by the rules of traffic, can not go to the convenience of the railing Oh! Here we will see what kinds of traffic can be divided into:

One, classification by use

　1. Traffic equipment in the parking lot include: marking, sign, angle protection, deceleration belt, wide angle mirror, parking lock, car blocking device, nail, summary standard, road gate, parking lot system and so on。

2、Highway traffic facilities are mainly: traffic signs, traffic signs, safety barriers, retaining nets, traffic signs and so on.;

Two. Classification by raw materials

　1, electronic products: indicator light, signal lamp, emergency light, energy saving lamp, intelligent road gate, charge system, solar sign, electronic monitoring, alarm device and other electronic transportation equipment;

　2、Hardware products: parking lock, sentry box, road gate, roadblock, road pile, sign, nail, barrier, fence, fence, stop shed, car blocking device and other hardware;

　3、Plastic products: wide angle mirror, deceleration belt, barrier bar, guard column, warning column, nail, locator, reflective film, marking belt, safety suit, safety cap, body paste, angle, road pile, road cone, summary mark, warning belt, anti collision bucket and other plastic transportation goods。
