Guardrail manufacturer: introduction of material and classification of high speed guardrail

      
       Highway guardrail is a semi-steel type protection product, and its corrugated guardrail plate is rolled by high quality Q235 low carbon steel plate. The surface is treated by hot galvanizing, spraying plastic and other treatment methods, and anti-corrosion and rust prevention treatment is carried out.

 

     

 

       During installation, the spacing between columns is generally 4m, while the length of wave guardrail plate is generally 4.32 M. because both ends of the column need to be fixed and spliced, the length is slightly longer. The length of high-speed guardrail plate is fixed, so the number of sets of high-speed guardrail can be calculated by measuring the length of pavement to be installed.

 

 

 

       The material selection of high-speed guardrail plate column is also very important. The diameter of steel pipe of general column is 114 mm and 140 mm, and the length can be customized according to the requirements.
