Applications
Metal guardrail can be used in parking lots,single and multi-lane highways, bridges, and bridge approaches.
Mainly used for the isolation and protection between highway and lane.
Applied to industry, agriculture, municipal administration, transportation and other industries to act as fence, decoration, and safeguard.Can be used in curves and slops, and the damage is easy to replace.
Steel highway guardrail can be divided into corrugated steel guardrail, square tube guardrail and steel wire rope guardrail in China. And people can also see other types of highway guardrail such as concrete guardrail, roller guardrail and some new innovation for highway steel guardrail in some area. In addition, according to surface treatment, it can be divided into galvanized steel guardrails and galvanizing plus plastic spray steel highway guardrail.

In addition, according to surface treatment, it can be divided into galvanized steel guardrails and galvanizing plus plastic spray steel highway guardrail.
According to location, it can be divided into steel roadside guardrails and steel median guardrails. According to anti-collision level, it can be divided into W Beam guardrail and three beam guardrail. Three beam steel highway guardrail is reinforced barrier, which is suitable for application of dangerous roadside sections, and W beam steel highway guardrail is used for special roads.
