50 mm thick panels at Baopeng / China

One of the largest AAC production plants in China, located in Liyang is now operating at full capacity. The superSMART plant produces blocks and panels of exceptional high quality, right at the heart of the Chinese AAC industry in the Jiangsu province.

High in demand are thin panels with thicknesses of 50 and 75 mm. The panels are vertically applied (floor to ceiling) and enable fast and easy installation. The new plant is already designed to cut super smooth surfaces, simply by adding Wehrhahn’s newly designed super smooth cutter.

The teams of Baopeng and Wehrhahn jointly managed to accomplish all targets set out in this project.
