Nantong Chaoli Rolling Machine is a plate rolling equipment manufacturer incepted in 1997. To ensure the quality of our rolling machinery and make them traceable, we have set up an archive system to record the production process, and have introduced many professional testing instruments for strict inspection.

Chaoli has established a complete set of quality inspection system for the raw materials, the semi-finished products, as well as the finished plate rolling machines.

Quality Control System in Chaoli
Raw material control

In the metalworking sector, achieving precision in shaping metal sheets and mastering various welding techniques is crucial for producing high-quality sheet metal products. Our hydraulic press brake and welding center are key to achieving these goals, catering specifically to the metal fabrication needs within the engineering and construction sectors.
