ZhongTuo 2/3 Waves Highway Guardrail Roll Forming Machine
different types of cold roll forming machines. We are a factory with a long history, engaged in the design and manufacture of roll forming machines since 2006. The machines we can produce include: roof tile making machine, cz purlin making machine, light steel keel making machine, metal embossing machine, door system forming machine, ceiling system forming machine, high frequency pipe welding machine, slitting line, cut to length line, shelf system forming Machine, floor decking forming machine, color stone tile production line, hot laminating filmed machine,etc.
The dual-wave barrier is a semi-rigid crash barrier featuring double corrugated profiles, composed of two continuous steel plates with wave-shaped peaks and valleys, circular tubular posts, support brackets/anti-blocking blocks, and connecting bolts, serving as a fundamental safety protection component for road infrastructure.
The triple-wave barrier is a three-layer corrugated reinforced high-protection barrier with widened panels and significantly enhanced cross-sectional stiffness, classified as a premium safety collision prevention facility primarily used for upgrading protection on hazardous highway sections.

Hydraulic pre punching & pre cutting
The cylinder diameter is 250mm and 120mm, with a stroke of 30mm. It has a four-column structure and the base is made of steel plate welded and tempered.
Punching station: 3 sets
Pre cutting blade material: Cr12MoV, heat treatment, HRC 58-62
Hydraulic station motor power:45KW, motor brand is Siemens Innomotics.
Conveyor belt: Used to convey the punched waste materials into the waste box.
Main roll forming machine
Forming machine frame: Made of high-quality steel sections, which are welded and then subjected to shot blasting or vibration treatment. It is machined by CNC numerical control gantry milling machine. Each rolling station has a positioning key groove on the bottom of the frame, ensuring the parallelism of the roller shafts.
Rolling station: 3W profile 20 rolling station, 2W profile 15 rolling station.
From 3W profile change to 2W profile, it is quick change. 3W and 2W share the same one machine basic frame. The 2W profile the distance of two rolling stations should be bigger than 3W profile.
