As one of the largest manufacturers in the aero performance sector, every product is engineered and validated to follow the ASTM Durability of Nonmetallic Material Standards. The ASTM's durability of nonmetallic material standards provides us for carrying out environmental exposure tests to determine the strength, service life, and weathering behavior of certain nonmetallic materials. These tests are conducted to examine and evaluate the algal resistance, light exposure behavior, activation spectrum, spectral irradiance and distribution, and microbial susceptibility of nonmetals, which include polymeric materials, glass, and plastic films. To reduce the chance of crack and break, we use high-quality Carbon Fiber and Polypropylene to mass-produce unique parts that are more durable than any other materials. Last but not least, with their years of experience, EOS knows how to give you the most reliable products and the most excellent deals. The people behind the business are experts in the field. With expertise, EOS will provide you with the best quality products and services.
