Composite manhole cover (valve) / Composite handhole cover (valve)

The entry of new areas of technology and related industries into 21st century urban life is obvious.

One of the old products used in urban planning is water and sewage canals, which could be accessed for maintenance by valves made of dry cast iron or other metals.

Other products in the family of valves are smaller access valves for underground shut-off valves known as handholes.

Acid rain and acidic liquids, the weight of cars and trucks, as well as the price of metals are the three main elements of the inefficiency of metal spout valves and metal handles, which we will discuss below:

Corrosion of metals due to acidic materials causes slipping and damage to all or part of the manholes (valves) and increases the risk of falling people and passing cars to be damaged.

- Pressure and wear resistance of metal manhole doors due to high weights, especially in cold or hot climates where metals show strong expansion and contraction effects will be very low.

- The high price of metals in the market has caused some profiteers to make money by stealing metal valves of municipal sewage, which as a result of the lack of these prestigious doors, while creating dangers for people and cars, gives an unfavorable image to cities.

- In addition to the above, the quality of valve production in terms of dimensions and size, continuous painting and other such issues has made the use of metal manholes and hand holes difficult.

The solution to the above problems has been created by relying on advanced nanotechnologies and polymer resins with the production of composite doors.

Composite cover in the form of manhole or handhole with different colors and the possibility of making special molds because of its features has solved all the problems of metal doors.

Matin Engineering Design Company is one of the leading brands in the field of polymer technologies in Iran in the field of manufacturing composite valves with ten years of after-sales service.
