Guardrail roll forming machine

Guardrails roll forming machine is one of most popular roll forming machines, two wave or three wave guardrails are optional. Different countries have different standards of highway guardrails, we design the guardrail forming machine according to customer’s profile drawing.

Features of guardrail:

The bending of the highway guardrail increases the aesthetics and increases the strength of the slab. Both are available. It is rolled by the forming machine. The surface is clean and undamaged, and the corrosion resistance is extremely strong. The surface treatment is mature; anti-corrosion, anti-aging and anti-corrosion The characteristics of drying, high and low temperature, the service life in outdoor environment can reach 10-25 years; The product structure is concise, beautiful and practical, easy to transport, install, good anti-theft performance, limited by actual terrain, for mountain, slope, multi-bend The zone has strong adaptability and moderate cost, which is suitable for large-scale adoption.

There are two types guardrails roll forming machine, they are two waves guardrail machine and three waves guardrail machine. I will show you some details about them in the followings.

Crash barrier roll forming machine

The crash barrier roll forming machine has been designed for producing w shaped guardrails with 2 wave and 3 waves or thrie beams placed on both sides of highway or expressway.

MTC designs and manufactures crash barrier roll forming machine for the making 2 waves or w beam and 3 waves or thrie road beam guardrails or guard rails. Typically one crash barrier roll forming machine produces only 1 type of guide rail. However, it’s technically available to make both 2 wave and 3 wave guard rails on the same machine.

The crash barrier roll former can work fully automatically from material feeding, punching holes , roll forming and cutting under control of PLC computer system. The produced crash barriers or guard rails have been applied for road or mostly highway/expressway construction.

In most of time, people use 10 gauge high-tensile galvanized steel (some with colour painted) to produce highway guardrails! At beginning, there are only 2-wave or w shaped beams with a two-rib corrugated design (with two secondary ribs). While in some other occassions, people must develop higher-tensile crash barriers with higher strength, and then we have 3 wave highway guardrails now.

crash barrier roll forming machine

This 3 wave or three 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.

Easily Operate Highway Guardrail Making Machine

To keep the driver safety, we need the highway guardrail making machine. We are specialized in making the highway machine. And our machines are easy to operate. We can make two waves, three waves for highway guardrail/fence application and two waves and three waves are made by one highway guardrail machine.  The following is about our easily operate highway guardrail making machine.

Production Standard: JT/T 281-2007, JT/T 457-2007

Raw material: Q235A galvanized steel sheet

Steel guardrails provide a visual and physical barrier between traffic and work areas. It is used for protection against accidents due to lift trucks or other mobile equipment in dock areas, aisles, around special equipment, or offices. Reduce costly damage to equipment and inventory. Modular system is easily expanded or moved as needed. For indoor or outdoor use.

Best Machine can make the best finished product to protect road against impact:

Poorly designed machine makes lower quality finished products. The guardrail terminal ends will lead to penetration of errant verticals, which could be extremely dangerous. So for the machine design, we are quite seriously.
