Features of ductile iron round manhole cover:
:
. Environmental protection: high-performance modified M sheet material, all raw materials meet environmental protection requirements and will not cause any pollution to the environment
. Save mineral resources: Under the current situation of increasingly tight domestic iron ore resources, our company has developed high-performance modified M sheets to replace traditional cast iron manhole covers, saving iron ore resources
． Anti-corrosion: Resistant to acid, alkali and salt corrosion,
does not rust, can be used in various harsh environmental conditions, and adapts to the temperature range
Wide: can be used under conditions from ℃ to ℃ use.
． Cast iron manhole covers are easy to transport, install, repair and construct with the same performance, which greatly reduces labor intensity
. Due to the special properties of the modified M sheet material: the product has strong plasticity, beautiful appearance, strong colorability, and rich color change. The whole material is used for coloring instead of spraying. Therefore, the color and luster of the product are smooth, and the hand feel is smooth and delicate, which is consistent with the tone of the surrounding floor. and floors
The materials can be coordinated, beautiful and practical
. Anti-theft: This material has no recycling value once formed and is naturally anti-theft, fundamentally eliminating theft, thus making up for the shortcomings of safety accidents caused by frequent theft of cast iron manhole covers. This product is equipped with a unique locking system independently developed by our company. , to achieve
anti-theft of equipment and facilities inside the well. It can completely prevent the occurrence of urban black hole accidents and bring great convenience to the management of municipal public departments
. Low noise: This product is made of non-metallic materials. There is no harsh metal impact sound when the car is rolled over, which greatly reduces noise pollution.
． It has a long service life. After testing by the National Construction Engineering Quality Supervision and Inspection Center, this product can withstand tens of thousands of anti-fatigue tests, and its service life can reach more than thirty years! It is the most ideal substitute for cast iron manhole covers.
