Beautiful appearance: simple lines, silver appearance, modern trend. Best drainage: the leakage area is 83.3%, which is more than twice that of cast iron. Hot dip galvanizing: strong rust resistance, no maintenance and replacement. Theft design: the cover and frame are hinged, which is theft-proof, safe and easy to open. Save investment: when it is long-span and heavy-loaded, it is cheaper than cast iron and saves the cost of stolen or crushed replacement. High strength: the strength and toughness are much higher than that of cast iron, which can be used in long-span and heavy-load environments such as docks and airports. Many specifications: meet the needs of different environments, loads, spans, sizes and shapes. The power cover plate is simple in construction, light in weight, good in bearing capacity, impact-resistant, bending rather than bending, large in displacement, beautiful and durable after hot-dip zinc treatment, and anti-corrosive, and has the advantages that cast iron cover plates are incomparable.

Power cover plate with hinge connection or hook connection, which is easy to open and has anti-theft function. Usage: It is widely used in Rongcheng foundation, garden facilities, residential quarters, schools, stadiums and other different places. Four production bases under Rongcheng Jianji Cement Products Factory in Panyu District, Guangzhou; Guangzhou Baiyun Jianji Cement Products Factory, Guangzhou Panyu Rongcheng Jianji Cement Products Factory, Huizhou Huicheng Jianji Cement Products Factory and Dongguan Songshulin Jianji Cement Products Factory have a total area of over 2 mu. Fiber reinforced materials are the most widely used and used in power cover plates. It is characterized by low specific gravity, high specific strength and high specific modulus. For example, the composite material of carbon fiber and epoxy resin has several times higher specific strength and modulus than steel and aluminum alloy, and also has excellent chemical stability, friction reduction and wear resistance, self-lubrication, heat resistance, fatigue resistance, creep resistance, noise elimination, electrical insulation and other properties.
