1 class, SA guardrail: it is the main form of semi-rigid guardrail, which is a continuous structure formed by splicing corrugated steel guardrail plates and supported by main columns.
2.SBM-class guardrail: also known as corrugated beam guardrail, is the main form of semi-rigid guardrail, which is a continuous structure formed by splicing corrugated steel guardrail plates and supported by main columns.
Second, the characteristics are different.
1, SA-class guardrail: increase the beauty and strength of the guardrail, and have both; Automatic production line extrusion, clean surface without damage, strong corrosion resistance; Mature surface treatment methods; Corrosion resistance, aging resistance, sun resistance, high and low temperature resistance, etc.
2.SBM-class guardrail: it combines rigidity with flexibility, has strong ability to absorb collision energy and prevent collision, has good line-of-sight guidance function, can coordinate with road alignment, has beautiful and harmonious appearance, can be used in small radius bends, and is convenient to replace damaged parts.
Third, the setting method is different.
1, SA guardrail: according to the position, it can be divided into roadside guardrail and median guardrail.
2.SBM guardrail: three-wave corrugated beam guardrail, column spacing 1m, embedded sleeve type.
