Machinery & Equipment

The most commonly used profile used in expressway construction is 2 wave guardrails which are produced by highway guardrail roll forming machine or expressway guardrail roll forming machine. We can design 2 different models of highway guardrail roll forming machine and expressway guardrail roll forming machine based on the differences of transmission,chain-brackets highway guardrail roll forming machine,and gear-boxes expressway guardrail roll forming machine. For each type,we design a different punching tools which can produce 8 holes at one time on the highway guardrails or expressway guardrails.We can produce both 2-wave highway guardrail roll forming machine and 3-wave crash barrier roll forming machine also.
