Shenyang Zishenlong specializes in the production of new energy-efficient building materials that are made of sandwich panels with high thermal insulation. These panels consist of a core with insulating material placed in between two durable steel or any other quality manufactured products. Such design not only improves the building’s max thermal resistance but also supports overall structural strength. Our policies on quality are kept with all International standards and this allows our products to be used in any country and guarantees the durability of the products.
