A vertically integrated Chinese rock-wool group, built on standards and patents.
From a single Zhejiang line to a 110,000 t/y group.
Ningbo Borui Trading Co., Ltd. is the dedicated international sales channel of the Xuanming Group — a Chinese rock-wool manufacturer founded in 2011 and now operating three plants across Anhui, Zhejiang and Shandong.
The group's flagship Anhui Xuanming facility sits on a 100-mu site in Guangde Economic Development Zone, runs a 70,000 t/y line and represents an RMB 200 million capital investment. Together with our Shandong and Zhejiang lines, total group capacity is 110,000 tons per year.
We are an early high-tech enterprise in the rock-wool sector, holding 45 technical patents (5 inventions), and we co-authored three of China's principal rock-wool standards including GB/T 25975. The group sits on the vice-chair of the China Insulation Association.
Borui exists to make that engineering capability available to international buyers — with English-speaking technical sales, export documentation, and FOB / CIF logistics from Ningbo, Shanghai and Shenzhen.
Fifteen years of rock-wool engineering.

A research culture, not a commodity factory.
The group employs 2 professor-grade senior engineers, 5 senior engineers and 6 master's-degree-or-higher staff, including a post-doctoral researcher. Our R&D base operates as the productisation arm of the National Ultrafine Powder Engineering Research Centre at East China University of Science and Technology.
This research depth is why our pipe sections deliver chloride content under 10 ppm, why our ETICS slabs are the reference product in national standards, and why our sandwich-panel lamella stays dimensionally stable through years of thermal cycling.
