<\/p>\nGuardrail system consisted of a series of components, including rails, posts, post caps, spacers, end terminals, bolts and nuts etc. Guardrails are used widely in the highway guardrail system\u00a0providing\u00a0a visual and physical barrier for\u00a0the vehicles and reduce costly damage to the vehicles. Then what\u2019s the timing to install the guardrails?<\/p>\n
<\/p>\n
The highway guardrail installation really needs skills that if you do not understand the installation techniques and steps, then don’t participate to do that. And because the guardrail itself is used for outdoor barrier, it has to resist the sun,the rain or even the baptism of cold ice and snow, the outdoor temperature and weather conditions varies due to the different seasons, which requires us to choose guardrail beams feature good durability and can’t break down under accidental bad weather.<\/p>\n
<\/p>\n
Guardrail beams installation are generally operated in the spring and autumn.The connecting bolts and splicing bolts for the beams should not be tightened up too early in order to be adjusted in time with the round holes of corrugated beams in the installation process,so that to form a smooth linear shape and to avoid partial irregularity. Spring and autumn are the good seasons for installation for that temperature is appropriate to provide convenience and protection for the transportation and installation work of hot galvanized beams.<\/p>\n

If the construction work of the beams is to be done in the winter, the big difficulties of installation and transportation are to be predicted. In the winter, the low temperature will lead to the phenomenon of soil frozen. If the soil is frozen, shoveling work would be a tough work. And because of the soil freezing, the soil moisture is difficult to volatilize. If the guardrail post is placed in such a soil,it’s easy to cause the phenomenon of erosion of the posts.And after the season changing, if the temperature rises, the phenomenon that frozen soil loosening, which will result in a number of beam not safe. So doing the installation work in the winter is facing great difficulties.<\/p>","protected":false},"excerpt":{"rendered":"
