Firstly, the etched metal shims, gaskets and washers make of wire in the form of a cellular web. The cells can have different calibers, depending on the type of metal shims, and the material, the diameter of the feedstock, the method of wire weaving determine the required consumer properties of such a metal shims fabric.
Initially, metal nets were made from brass and copper alloys on looms, very reminiscent of weaving. They were good to use to filter liquids and gases in technical devices.
Secondly, they learned how to draw wire from iron and weave various products from it in antiquity. So, in Ancient Russia, warriors wore chain mail woven from small metal rings, the chivalry of Medieval Europe also good to use this protection in the service.
But on an industrial scale, the metal shims began to be produced with the advent of the first machine industries, that is, at the time of the industrial revolution.
For construction needs and finishing works, fine- etched metal shims, gaskets and washers is most good to use. It is divided into the following types:
Most often, such etched metal shims, gaskets and washers are made from carbon steel, but there are also metal shims made of alloyed (stainless) steel, a variety of alloys that improve the consumer characteristics of the metal shims or add special properties to them.
As well as, woven nets are produced using the technology of interlacing the warp and wire by the method of crossing in the transverse direction. This type of metal shims can be recognized by the spirals of round or flat wire woven into one another.
An etched metal shims, gaskets and washers is made by twisting each wire with two more on both sides in the transverse direction.
The cut-and-draw type of the grid is made of sheet metal. Through cuts (notches) are made on the surface of the sheet, and then the sheet is pulled in the desired direction.
The classification of etched metal shims, gaskets and washers bases on two bases: by the type of coating and by the shape of the cells.
In addition, there are types of metal shims according to the type of coating:
Despite the theme of our online store, we emphasize that the use of metal shims is possible not only in construction and repair. The range of its suitability is unusually wide - from the automotive industry to space!
Moreover, the slotted type of metal shims weaving is distinguished by the preliminary stage of manufacturing vertical parallel grates with shaped section loops, on which metal studs are then attached.
Furthermore, welded etched metal shims, gaskets and washers obtain by spot bonding the wire at the intersection of the threads, using welding equipment.
Subsequently, this is one of the most economical types of metal shims. It is good to use in the process of finishing work for cladding and plastering walls. The required cell size, the thickness of the products and the required cutting step are determined according to the degree of complexity of the forthcoming work.
The standard notch pitch is 0.6, 0.8, 1.0, 1.5 mm. The thickness of the sheet metal itself can be 0.6, 0.8, 1.0 mm. Experts recommend taking an expanded metal product with cells 17 by 40 millimeters for leveling surfaces with plaster.
It is intended for strengthening during cement work, pouring the foundation, concreting and other operations in which reinforcement of structures requires. Since it is usually laid around the perimeter, or in a certain corridor (formwork), builders call such a grid an armored belt.
Eventually, it can be distinguished by such a feature as notches every 2-3 mm - to increase adhesion with the solution.
Fine etched metal shims, gaskets and washers is good to use for various types of finishing work, but this material is also in demand in other construction works. It prevents the formation of cracks and crevices on facades, walls, floors or ceilings, that is, it reinforces them.
But the main thing is that such a etched metal shims, gaskets and washers perfectly interacts with any type of finishing material: waterproofing, plaster or putty. Any self-respecting builder can no longer do without it. She flies in a special way.
Main advantages:
We must not forget about another important advantage - fine- etched metal shims, gaskets and washers shims significantly reduce the consumption of building materials. The price of a metal shims is much lower than the cost of the same putty or plaster, but with it the finish will live much longer.
Fine etched metal shims, gaskets and washers are of the following types:
Most often, this material is made from carbon steel, but sometimes a metal shims comes from alloyed or stainless steel and even from non-ferrous metals and their alloys (copper, brass, aluminum).
The old problem of our country is fools and roads. If the first problem is very difficult to cope with, then the solution to the second is available with the help of modern construction methods. Etched metal shims, gaskets and washers are often good to use for road construction. It consists of BPI reinforcement wire, which joins by spot welding.
During the laying of the road, such material lays on the prepared base, and then poured with concrete.
