Manhole covers are generally divided into round and square, in the city's road governance, Jiangxia composite covers, generally circular, because a circular covers easy to tilt, Wuhan composite covers production, can better protect pedestrians and vehicles Security. Circular, mainly on account of the circular center of each of the covers through its diameter is the same length, so if the covers are rolled from passing vehicles, because no matter how rolling onwards, its diameter will be more than slightly below the wellhead wide, Wuhan Buying composite covers, covers not fall wellhead go. Composite covers technical features: light covers weight, easy to transport and install, can greatly reduce labor intensity. The new resin covers have a good anti-theft performance, because the synthetic resin material no recycling value, Wuhan composite covers size, effectively put an end to the "urban black hole" appears. Composite covers high accuracy, corrosion resistance, high temperature molding production, with good acid, corrosion-resistant ability, effectively extending the life of the resin covers.
