Is the reinforcement of sa guardrail welded or bound?

This kind of reinforcement is the way of binding.

According to Baidu Encyclopedia, sa-class guardrail steel bars are generally high-strength steel bars, and welding will affect the strength and toughness of steel bars, thus affecting the overall stability and safety of the guardrail. Therefore, through binding, the close connection between the steel bars and the columns can be ensured, thus improving the overall stability and safety of the guardrail.

Steel binding method is as follows:

1. Strengthen the strength and toughness of concrete structures: steel bars are the main load-bearing components in concrete structures. Fixing steel bars in concrete by binding can enhance the strength and toughness of concrete structure and improve its bearing capacity and seismic performance.

2. Convenient maintenance and repair: the binding method can make the connection between steel bars and concrete more firm, facilitate the later maintenance and repair, and prolong the service life of concrete structures.
