The lid of the hatch is square

## Luke Square: an inconspicuous hero under our feet
Every day we walk the streets, without thinking about what is under our feet. And there is a whole underground world: communications, cables, pipes. And over this world, strong, often invisible, hatches of hatches are vigilantly standing. Today we’ll talk about the square lids of hatches - not as common as round, but no less important.
### Why exactly the square form?
Round lids of hatches are known for their resistance to failure, because a circle is the only form that cannot fall into a hole of smaller diameter. But the square form has its advantages. Firstly, square lids allow more effectively using the space, tightly adjacent to each other and forming an even surface. This is especially important when planning a roadway. Secondly, the square form can be more convenient for installation and maintenance, providing simpler access to underground utilities. Thirdly, sometimes designer solutions dictate the choice of a square form, harmoniously fit into the overall architectural style.
### Material and strength: durability underground
The square lids of hatches, like their round counterparts, are made of various materials, the choice of which depends on operating conditions and the necessary strength. Cast iron, concrete, composite materials - all of them are able to withstand significant loads from passing transport and pedestrians. Modern technologies allow you to create lids with high wear resistance, providing a long service life even in the most difficult conditions. It is important to remember that strength is not only the protection of underground utilities, but also the safety of pedestrians.
### Aesthetics and urban environment
Do not forget about the aesthetic side of the issue. The square lids of hatches can be not only functional elements of urban infrastructure, but also part of the general architectural ensemble. The variety of colors, textures and even decorative elements allows you to fit them into the environment, making them almost invisible or, conversely, turning into small works of street art. The square form opens up wide opportunities for design experiments, allowing you to create unique and harmonious solutions for the urban environment.
