YUANDA is the name of the company and the fully integrated building system with Autoclaved Aerated Concrete (AAC) panels and blocks, perfect for commercial, industrial, educational, public and residential projects.

YUANDA Shandong state-of-the-art manufacturing facility is located in Qingdao, Shandong. The 180,000 square meters facility is designed to efficiently produce blocks and engineered panels for rail or shipment transport throughout the world.

AAC Panel was developed by a Swedish architect, and was patented in 1924. The architect was looking for a construction material which has the properties of wood thermal insulation, solid structure, easy to work with and handle but without the disadvantages of combustibility, decay and termite damage. At that time there were only small, heavy building blocks with poor insulation properties. He succeeded in producing a highly cellular, lightweight material from quartzite sand, lime and water.

These raw materials can be found in almost unlimited quantities throughout the world. They are processed with cement and a rising agent to provide a building material with a large number of air pores aerated concrete. And it is precisely these pores, in addition to the solid structure of calcium silicate hydrates, which give YUANDA its exceptional product properties: fire resistant/non-combustible, superior thermal insulation, excellent acoustic insulation, lightweight, termite and pest resistant, ease of workability and handling, universal application, non-allergenic, and efficient construction.

Environmentally friendly and energy-conserving, YUANDA meets all the requirements of our modern life. Absolutely no pollutants or hazardous wastes are generated in the process and there is no waste of precious raw materials. Pure YUANDA, not containing any foreign materials, can be recycled into other useful products.

Even the production method conserves energy since steam curing is carried out at high pressures and thermal energy is recovered and reused for maximum efficiency. Production trimmings can also be fully recycled, again making YUANDA Panel a highly efficient and environmentally compatible building material.
