The automobile has become a major industry in the world, and with it comes people’s safety issues.

Mr. Fricens from Saudi Arabia recently contracted a project and wanted to buy a highway guardrail cold roll forming machine . He found our Liming stamping form machine Co., Ltd. on Alibaba. We provide a No glitches, exquisite appearance, and stable forming highway guardrail cold roll forming machine, which solves the problem of Mr. Fricens producing high-speed guardrails during the production process.

The problem of burrs occurs when the plate is cut, which meets the requirement that the profile will not be unable to be installed during the installation process. All the parts of our machines use standard parts, and we have compiled  machine documents for each machine. If the parts of the machine are damaged, you can purchase the parts of the machine in the local market in Saudi Arabia according to our machine documentation, saving transportation time, reducing machine downtime and saving costs. In order to solve the internal wiring confusion of the electric control box, we established our own electric control team in 2015, which not only ensures the quality and safety of the machine, but also brings great convenience to future maintenance and repairs.

Mr. Fricens was very satisfied with our highway guardrail cold roll forming machine and gave a good evaluation of our online factory inspection service. We have also become good friends.
