Zhejiang Kaiyuan new wall materials New Century Tourism Group Co., Ltd. is based on "industrial linkage development" strategy, in 2005 the introduction of Germany Wenham (WEHRHAHN) automatic production lines and proprietary technology, to invest about 200 million yuan to build the autoclaved sand plus Aerated Concrete (AAC) product development and production company, is currently the highest level of technical equipment, can also produce plates and blocks of single-line production capacity of the largest AAC production line, but also the first in Zhejiang Province AAC board production line with annual production capacity of 400,000 cubic meters, equivalent to 260 million standard bricks. The company also has an AAC product test center with international advanced level.

The company's main product is a dry density of 300-750 kg / cubic meter of AAC blocks and reinforced sheet, with light, heat insulation, fire resistance, sound insulation, load, seismic and non-radioactive, etc., can be used as building infilled , partition walls, load-bearing walls, wall decoration, roof, floor. AAC is so far only able to meet without composite wall material innovation and energy efficiency requirements of greater than 50% of a single material lightweight construction materials, concrete frame structure is not only widely used in construction, but also recognized as the most suitable steel building enclosure wall body.

The company has selected the national new wall materials advanced enterprises, the National aerated concrete industry's most influential companies, new wall materials production model line in Huzhou City, Zhejiang Province, as well as advanced manufacturing base demonstration projects for national standards, "autoclaved aerated concrete board "(GB 15762-2008)," autoclaved aerated concrete performance test method "(GB / T 11969-2008) and construction standards Zhejiang Province," autoclaved aerated concrete application of technical regulations "block (DB33 / T1022 -2005) AP units, Zhejiang building Standard Design Atlas "autoclaved aerated concrete (AAC) panel construction detail" (2010 Zhejiang G33), "autoclaved aerated concrete (AAC) blocks construction detail "(2010 Zhejiang G34) editor units, the China Association of aerated concrete units, and passed the ISO9001 quality management system and ISO14001 environmental management system certification.

Currently, the company's products are widely used in public buildings, government agencies, high-grade office buildings, stadiums, high standards of plant and large-scale residential projects, and exported overseas, domestic and foreign users of praise, is the industry recognized high sand aerated concrete products.
