Drainage grates: purpose and varieties

Drainage grates are an integral part of not only urban communications, but also the land near the house. They are designed to perform several functions and have special characteristics and properties. After examining the shower lattices, you can be sure that they are not as simple as it seems at first glance. After all, they not only complement drainage sewage, but also add aesthetics to the surrounding space.

In the park areas, these structures become a kind of protection for the rest from injury. Thanks to their device, they reliably close the drainage channel, which prevents possible fall into it.

The installation of drainage systems on the carriageways or road congresses is carried out in such a way as to ensure the smooth passage of vehicles. In addition, they are able to withstand a huge weight, which allows them to maintain the original appearance even after the passage of very heavy cars.

Drain nets not only protect the drains from falling into large debris, but also serve as a decorative element, completing the installation of the system. And due to the variety of shapes and colors, they can decorate any territory of a private household.

Protective nets are used for elements of the drainage system. In the form of a grid, trays are often made of a linear type, point inlets, sand traps and cast iron hatches.

All storm lattices are distinguished according to the material of manufacture, the method of installation and the load. Speaking about the material, there are several types.

These are water intake grids, which are usually installed with concrete and iron gutters in places with high loads. They have a lot of advantages, among which we can highlight the high resistance to various environmental influences and corrosion. Besides, cast iron system is strong enough, durable and affordable. You can buy products in any specialty store and at an affordable price.

Due to its operational properties, cast iron structures are used in industrial facilities, sea and air ports, as well as in places with a large flow of trucks.

Metal constructions are made of stainless or galvanized steel, which improves the quality. The stamped steel system has a light weight, an attractive appearance, and can be made to order in any size. It is reliable and durable, and mount it simply due to special latches.

Galvanized steel has high strength and availability, but is not intended for installation in places with high loads. In addition, it is prone to corrosion.

It is expensive stainless steel welded grille, which is important to consider when creating a project.

Ideal for installation in recreation areas and in the territories of private houses. They are distinguished by low weight, low cost, and resistance to chemicals and temperature extremes.

Most often, such options are used to underscore the status of the owners. Lattices made of copper have a beautiful appearance, but differ in high cost. In addition, they are not designed for high loads.

Depending on the structure, the drainage systems are divided into two types: slotted and cellular grids. They differ only in the form of the located internal partitions, and have no significant differences.But the water-receiving cellular construction for trays, unlike the slotted one, better allows sewage to pass through and more reliably protects the sewage system from the entry of debris.

The storm water grids can be classified according to the load according to the weight that this product can withstand. It is important to understand that this indicator represents the largest weight that the structure can withstand. This must be taken into account when choosing.

Classification drainage occurs using six steps. Each stage displays individual characteristics.

• Class b can be installed on a busy street as it will not withstand a load of more than 12 tons. The higher the class, the higher the allowable head.
• Class A designed for loads up to 1.5 tons, and therefore can only be used in areas where they move on foot or by bicycle. But class C can withstand a weight of more than 20 tons, which allows it to be installed on the roads of medium intensity of movement of vehicles and at gas stations.
• Category D It is intended for location on busy roads, as the maximum weight that it can withstand is 40 tons.
• Even higher rates have category Ewhich is applied to drains in port and industrial facilities.
• The highest loads can endure class FTherefore, its direct purpose is to protect the drain at airports and other large places.

By way of installation allocate overhead and fixed mesh.

• Overhead devices are placed directly on the tray. They are used in deserted places that are reliably protected from severe mechanical loads.
• Fixed grilles are fastened with a dowel, and can be installed in any places.

The selection of drainage grids for drainage should be based on the following factors and criteria:

1. The main thing - the correct choice of load class and material of manufacture. From these indicators depends on the use and service life of the drainage system.
2. The size of the stormwater elements must cope with large streams of water. Small grids have low bandwidth, and therefore are practically useless.
3. The price of the product is not the last place. The higher the cost of the device, the better its operational properties.But there is no need to install concrete trays and steel gratings for drainage in the garden area or on a pedestrian walkway; it is quite possible to limit it to plastic systems.
4. If the installation of the structure will be done personally, it is important to choose the easiest option. Such is plastic, which is easy and simple to assemble. But for the laying of steel mesh will need the participation of several people.

The choice of storm nets directly depends on their purpose. Therefore, there is no definite answer to the question of what they should be.
