With decades of development, the technique of Guang Jing Aluminum materials have been updating. Till now, the Oubuys Ceiling can provide various projects clients with metal Aluminum ceiling material of diversified environments, can not only bring the top grade beauty effects but also takes into consideration of the application environment. Guang Jing Aluminum Ceiling provides clients with 3 grades of Aluminum ceiling materials. The first type is Aluminum-Magnesium Alloy with part of Manganese. The best advantage of this material is the good anti-oxidative capacity. The appropriate adding of Manganese improves the strength and stiffness, which is the best material for ceiling. The second type is Aluminum-Manganese Alloy. This strength and stiffness of this material is better than that of Aluminum-Magnesium Alloy but with a comparatively weaker anti-oxidative capacity. The third type is Aluminum Alloy, with a less content of Magnesium and Manganese, the strength and stiffness of this material is obviously less than that of Aluminum-Magnesium Alloy and Aluminum-Manganese Alloy and with an ordinary anti-oxidative capacity.
