As a manhole cover manufacturer,there are many friends who require composite manhole covers.Those who use composite manhole covers know that composite manhole covers use unsaturated polyester resin as the matrix,reinforced materials,fillers,etc.,and are made using compression molding technology.It is a new type of environmentally friendly inspection manhole cover.So what are the advantages of composite manhole covers?Let's take a look together.

　　1、Strong weather resistance:The manhole cover can be used normally in environments ranging from-50℃to+300℃through scientific formula,advanced technology,and complete technical equipment.

　　2、Beautiful appearance:The surface pattern design is exquisite,and the color is bright and adjustable,beautifying the urban environment.

　　3、High strength:It has high compressive,flexural,and impact strength,and is resilient.After long-term use,the product will not experience crushing or damage to the manhole cover.

　　With the rapid development of supporting facilities for newly-built residential areas and roads in urban and rural areas,the demand for composite manhole covers has sharply increased.Due to their resistance to acid and alkali,corrosion,wear,and vehicle rolling,they are easy to use,lightweight,easy to transport,install,and repair,greatly reducing labor intensity.

　　The above are the advantages of composite manhole covers.I hope they can be helpful to everyone.If you want to learn more,please feel free to call for consultation.
