4.The history of honor. By the end of 2018, highway guardrail factory has provided engineering services for the construction and installation of expressway guardrail plates for more than 700 projects. This is an unparalleled competitor.

Quality is the only standard of choice

Everyone has seen the highway guardrail, but many people do not understand his production process and think it should be very simple. The extrusion deformation of the steel plate through the guardrail plate machine is completed. In fact, it is only a very small process in the production process of the guardrail plate. Now I would like to introduce some production techniques for guardrails.

The raw material of highway guardrail is a high quality steel plate that conforms to the national standard. The staff need to select the steel plate, and the next step can be carried out after the inspection of the qualified product.

The selected highway guardrail will be transported to the guardrail production workshop. During transportation, we should pay attention to not scraping the steel plates.

We need to carry on the removal of highway guardrail into the workshop, we can only plastic removal of his cleaning, polishing machine etc.. Then the steel plate is extruded through the guardrail production equipment, some are extruded into two wave guardrails, some are extruded into three wave guardrails, and then punched.

Next, the highway guardrail factory also need to degrease the highway guardrail with acid wash. Degreasing is very important because next we need to carry out anticorrosion measures for the guardrail. Before hot dip galvanizing or dipping, we need to wash, phosphating and drying.

The choice of different highway guardrail at high speed sections is different

In the rain and snow, fog and haze weather, the highway guardrail due to the effect of reflection, the driver can give the driver correct guidance, to ensure that it has a clear direction.

When buying a highway guardrail, you need to determine what level of protection is needed, or directly tell the highway guardrail factory where to install it, such as the middle of the village road belt, the highway isolation belt, the expressway both sides and other places, the guardrail manufacturers will clearly give the specifications of the barrier board requirements. The guardrail board is divided into five levels: B, A, SB, SA and SS. The intermediate barrier plate is mainly distinguished from the wave shape and material quality of the guardrail plate. In terms of protection effect, it can also be divided into two wave guardrails, three wave guardrail plates and two wave three wave transition plates.

The highway is inseparable from the protection of highway guardrail. Many people feel that the guardrail boards are the same. Actually, there are differences in the guardrails of different sections. So what section of the fence should we choose? Generally, it is easy to collide on the turning road. When the vehicle turns, it is easy to rush out of the expressway because of poor speed control. Therefore, we need to install a guardrail plate with higher protection at the corner.

the highway guardrail factory The concrete foundation construction should pay attention to the concrete foundation construction in summer.

1 .construction as short as possible transportation, pouring, vibration and other process time, pouring should be covered in a timely manner, watering maintenance.

2 .concrete mixing should have shading shelter. The surface of foundation pit should be watered before pouring concrete.

3 pay attention to weather forecast. If rain falls, construction should be suspended.

4 .when temperature is high, it is advisable to avoid construction at noon.
