Fiberglass Reinforced Polyurethane Composite Profile Processing Services（OEM）

    G-Ren Tech, together with HUNTSMAN, jointly launching the epoch-making high performance energy-saving door and window material -- fiberglass reinforced polyurethane profile. Apply the composite material that widely used in the aerospace field to the civil door and window system, leading the innovation of a new generation of door and window materials.

    By own professional technology, G-Ren independently researches and develops the injection box, mold and a series of design and production process for polyurethane composite complicated section pultrusion. Besides, cooperate with the customized polyurethane resin for pultrusion that jointly researched with HUNTSMAN. Till now, G-Ren's polyurethane pultrusion process can realize the stable production for a long time, and achieve the qualified rate of 95% or more, which is in the advanced level among the same industry in the world. A number of international enterprises, including LG of South Korea, are conducting in-depth exchanges and cooperation based on the existing design and production technology of G-Ren, with a view to introduce this product and related technology into the local market.

    In 2019, G-Ren was recognized as a high-tech enterprise, and in 2020 won the leading award of “Demonstration Project, Innovative Technology” by Shanghai Construction Association. Besides, G-Ren was shortlisted in Beijing Energy-saving Technology Recommended Directory(2020 Edition) and the Yangtze River Delta region energy saving product catalog composition. At present, G-Ren has more than 20 patents of invention, utility model and appearance design. G-Ren is certificated by the UKAS quality management system ISO9001-2015; Environmental management system ISO14001; Occupational health and safety management system ISO45001. And participated in the preparation of "T/CECS 591-2019 Fiberglass Reinforced Polyurethane Doors and Windows Engineering Technical Specifications", Beijing "DB11/891-2020 Residential Building Energy-saving Design Standard", "aluminum alloy - polyurethane profiles", Beijing "Residential Building Doors and Windows Engineering Technical specifications" and other standards and design specifications. 

    In the backgroundof the global emission reduction, energy saving requirements for the doors and windows have been raised in every country in the world. Fiberglass reinforced polyurethane composite, as a new energy saving material, has gradually received wide recognition around the world. Including VELUX in Denmark, Inoutic in Germany, Pella in the United States, and many other well-known window companies have similar products as their series of high-end products to the market.

    Based on the advantages of sound upstream and downstream industrial chain, polyurethane pultrusion industry in China has considerable advantages over European and American countries in raw materials, equipment manufacturing, mold processing, coating technology, door and window manufacturing, and professional technical personnel training. At present, in the polyurethane door and window pultrusion industry, G-Ren is in a leading position in terms of product series perfection, product quality control, and the quantity of mass production, also has reached cooperation with some of the world's large doors and windows brands.

    Currently, G-Ren operates the manufacturing facility in Dafeng District, Yancheng City, Jiangsu Province. With 16 pultrusion production lines, the plant achieves the total annual output capacity of up to 5,300 tons of fiberglass-reinforced polyurethane composite profiles.  

    G-Ren Tech provides professional pultrusion profile processing services from product section optimization, mold design, mold and profile production and a full set of technical solutions for customers in various industries around the world.
