About US
oushangya, formerly Junhai Building Materials, was founded in 2003 and is located in Dongguan, Guangdong Province. In 2014, we officially registered our own brand, focusing on the research and development, intelligent manufacturing, and customized services of aluminum alloy extremely narrow panoramic system doors and windows.
Based on more than 20 years of industry accumulation, we have multiple original patents. Create a highly weather resistant door and window system tailored to the climate characteristics of coastal areas with frequent rainfall, typhoons, and high temperatures. Our main products include extremely narrow system windows, heavy-duty sliding doors, and intelligent lifting windows. Our products are soundproof, heat-insulating, moisture-proof, and corrosion-resistant. We carefully select high-quality accessories throughout the entire process, balancing minimalist appearance, safety performance, and cost-effectiveness. We can provide integrated door and window customization solutions for villas and large flat floors.
ENVIRONMENT
Nature and sustainability
In Auchan, environment and nature have always been very important - after all, we try to integrate them into space and create a free flowing transition. For us, there is no doubt that we strive to protect them and constantly check our processes to optimize the use of resources. This allows us to avoid wasting resources and energy.
Especially for this reason, we have invested in a photovoltaic system for the user's new building and integrated a sunshade with grass vegetation on the facade, which provides shade in summer and extra light for the building in winter.
