Composite manhole cover is one of the most popular composite products globally.
Due to its composite features and related unique capabilities, this product has been able to achieve a good position among competitors in market.
The composite manhole door, unlike the metal manhole door, has a higher security, since the metal manhole valve with a lot of weight, and also the nature of iron or steel cost, is not be stolen and can be mentioned as a hard duty component in high pressure and chemical materials contact.
In composite manhole cover, based on molding and structure type, the frame and installation is without slippage and error.
The manhole composite lid has other features like:
1. Electrical resistance
Due to the composite material structure, electricity cannot be stored/shared on surface or internal layers of these doors.
2. High pressure tolerance of 90 newton
In high-pressure locations such as streets and factories, a composite valve can be one of the best choices.
3. Ability to produce different sizes and shapes based on customer order
According to the composites included in these doors, the door can be produced in different shapes as well as with custom logo.
Matin Technical Design Co. has done a project with a different size of manhole composite door for a company in Fars industrial zone, which is described as follows:
The manhole door was produced in diameter of 60 cm in blue color with its square frame, size 76 * 76 in 2017.
