The welded grid is one of the most commonly used building materials, it is made of steel wire, pieces of which intertwine in directions perpendicular to each other, and then weld. The product made in this way has high strength and ability to withstand enormous loads, without deforming at the same time. Products such as masonry, as well as road and reinforcing nets are often attributed to welded grids.
The welded grid is made of high -quality low -carbon steel wire. Steel has excellent resistance to changing weather conditions, corrosion, high loads, dampness and cold. Actually, this is why the steel welded grid is so widely used in a variety of types of work, in particular, in the manufacture of the roadway.
There are galvanized welded nets, as well as a polymer coating grids. Such products are even greater than strength, wear resistance and durability.
The welded mesh is made on welding machines. Professional equipment used to create this product provides its high quality and reliability. When creating a welded grid, a point welding method is used.
The strength of the steel welded grid depends on several factors. So, the diameter of steel wire, as well as the size of the cell, directly affects the ability to easily withstand huge loads. The most durable nets are made of thick wire and have very small cells. Thus, the strength of the welded grid directly depends on the amount of metal per square meter of the product.
Varieties of the welded grid welded mesh are divided into several types according to different criteria:
By the shape of the cells:
zero hexagonal rectangular rombic trapezoid -like square cells:
The lesser — the cell area is not more than 0, 025 mm2 the smallest — the area of the cell is from 0, 025 to 0, 25 mm2 small — the area of the cell is from 0, 25 to 1 mm2 medium — the area of the cell is from 1 to 25 mm2 large — the area — the area — the area — the area The cells are from 25 to 625 mm2 is very large — the area of the cell is 625 mm2 and more by the type of galvanizing:
The net was first galvanized, and then welded (electrolytic galvanizing method, a zinc layer is 10 grams per square meter. m.)
The net was first welded, and then galvanized (the electrolytic galvanizing method, the zinc layer is 20 grams per square meter. m.)
The grid was first galvanized with hot zinc, and then welded (a layer of hot zinc is 50 grams per square meter. m.)
The grid was first welded, and then galvanized with hot zinc (a layer of hot zinc is 130 grams per square meter. m.)
It is important to remember that the larger the ratio of zinc/sq. m., the stronger the product itself.
The main undeniable advantages of steel welded grid are high strength, reliability and wear resistance of the product and at the same time its very low cost and ubiquity. You can buy a welded grid in any specialized store or in the construction market. In this case, this product can be used in many areas of construction. The steel welded grid is especially in demand when laying road paintings.
Where else, in addition to road construction, a welded grid is used? In industrial and municipal construction, when reinforcing (increasing the bearing capacity) of masonry, floors, glass, plaster, thermal insulation. In addition, steel welded mesh is widely used in the manufacture of frames for different types of greenhouses, ventilation grilles, cells and aviaries for birds and animals, as well as when protecting the territory.
