lid of the hatch of the well square

## cover of the well of the well: reliability and practicality
Square covers of wells of wells - the usual element of the city landscape, inconspicuous, but extremely important. They ensure the safety of pedestrians and vehicles, reliably hiding underground utilities. In this article, we will consider some aspects of this seemingly simple product.
### materials and strength
What are these inconspicuous heroes of our streets made of? Most often, cast iron is used for the manufacture of square lugs of hatches, known for its strength and durability. This material is able to withstand significant loads - from the weight of cars to random falls of heavy objects. However, modern technologies do not stand still, and covers of composite materials appear that are lighter than cast -iron analogues, but at the same time have sufficient strength and resistance to corrosion. The choice of material depends on the alleged loads and operating conditions.
### Security First of all
Security is a paramount task in the design and manufacture of hatches covers. The square form, unlike the round, does not allow the lid to fall into the well. Even if the lid shifts slightly, it does not fall inside. In addition, it is important that the surface of the lid is non -rustle, especially in rain or snow. For this, manufacturers use various textures and coatings that provide good adhesion with shoes. Some modern models are equipped with reflective elements that increase visibility in the dark.
### Aesthetics and environment
Previously, the hatches cover were quite incredible. Today we see attempts to give them a more aesthetic look, entering them into the overall design of the urban environment. There are covers with various patterns, flowers and even images. This approach not only improves the appearance of the streets, but also cheers up to pedestrians. In addition, it is important to remember the environmental aspect. The use of redesigned materials and reduction in the weight of the product helps to reduce the environmental trace. In the future, we can expect the emergence of even more environmentally friendly and aesthetically attractive covers of the hatches of wells.
