As a complementary equipment, a 3 wave highway guardrail roll forming machine has been designed for the manufacturing of 3 waves or thrie beams guard rails for highway or expressway construction.

3 wave or thrie beam crash barriers application

There are always two types of road beams or crash barriers placed on the two sides of highway, or expressway: Two wave guard rails or W-shaped beams, and Three wave or thrie beam crash barriers. Most of the guard rails are 2 wave or w shaped beams (More about w beam or 2 wave highway guardrail roll forming machine) but in some occasions, 3  wave or thrie-beam crash barriers are necessary to installed on the highway or expressway (the most common applications for 3 wave or thrie-beam guardrails are bridges on highways , or exit and entrance of tunnels on highways).

Brief introduction of 3 wave highway guardrail roll forming machine:

This 3 wave or thrie beam crash barrier roll forming machine is a cost-effective and heavy duty production line. It produces 3 wave guard rails fully automatically and continuously out of galvanized steel (sometimes cold rolled steel) of 2-3.5mm thickness  in the same way as a 2 wave or w beam highway guardrail roll forming machine does, from material feeding all the way until running out from the main machine.

Not like a 2 wave or w beam highway guardrail roll forming machine We offer only gear-box and universal-joint shafts transmission system, and separate forming stands structure for a 3 wave or thrie beam crash barrier roll forming machine. (There is interchangeable highway guardrail roll forming machine for the production of both w beam and thrie beam.)

Main components for a thrie beam or 3 wave crash barrier roll forming machine are listed as a 10 Ton hydraulic decoiler with coil car, a feeding guide, a leveler, a hydraulic punching tool, a roll forming part, a hydraulic cutting tool, a transmission system, a PLC control cabinet, a hydraulic oil pump and runout tables.
