Steel wire is the simplest and most widely known metal product. The form and method of its manufacture are simple, but ... there are subtleties everywhere - and such a seemingly uncomplicated hardware, like steel wire, also has its own characteristics, which are regulated by the relevant GOST. There is also a GOST for the most common type of steel wire - general purpose.

There is also a GOST for the most common type of steel wire - general purpose.

The diameter of this product can be very different - from tenths of a millimeter to several centimeters, but the most commonly used will still be rolled products with a thickness of 0.8 mm to 6 mm., Made from steel grades 08kp, St10ps or St10 by cold drawing.

All these types of steel are low-carbon, they are highly flexible.

The wire obtained from them belongs to the category of "general purpose" and can be produced both with an additional coating and in its pure form.

Low-carbon wire is usually divided into two categories: heat-treated and non-heat-treated. Heat treatment reduces the elasticity of the wire and increases its bendability - therefore, nails can be made from this wire, and the wire itself can be made from heat-treated wire.

The heat-treated wire can be light (if it was calcined without access to oxygen) and black (if it was covered with an oxide layer as a result of interaction with atmospheric oxygen - turned black). Black wire is considered to be more resistant to corrosion, but it will be more difficult to coat it with another rust-preventing compound - therefore, consumers prefer to order wire with a light version - it can be coated with zinc, varnish, etc.

As for the use of such wire, one of the most common options for its use is the fastening of reinforcement. So steel wire general purpose is often also called "knitting" - suitable for its properties for tying reinforcement. General purpose wire produced in accordance with GOST 3282-74 is best suited for these tasks.

It is used in the manufacture of reinforcing reinforced concrete frames wherever the use of welding is not specifically stipulated - that is, in most reinforced concrete products. You can easily teach any worker to fasten reinforcement bars with it, and you can simply check the quality of his work by eye - there is right places wire ties or not.

But the minimum requirements for the worker dictate rather high requirements for the material.

What exactly? This is what GOST 3282-74 says.

Main indicators

First of all, it contains requirements for the mechanical characteristics of the annealed wire. GOST provides that the relative elongation of the heat-treated wire should be in the range of 15-20% for "bare" wire, or 12-18% (if the wire is coated).

GOST 3282-74 also divides the wire into several varieties:

• in terms of production accuracy for normal and increased accuracy;
• according to the processing method - annealed and unannealed;
• by type of surface - with and without special coatings;
• by tensile strength (for wire that has not undergone heat treatment) - for products the first and second groups;

For non-heat-treated wire, the main indicator will be tensile strength, which should have the following values:

To control these main indicators of the quality of the binding wire, GOST requires acceptance finished products, testing mechanical characteristics in 3 percent of coils or coils from each supply lot.

The geometric parameters of the wire (thickness and cross-sectional shape) should be checked for 5% of the coils, and the surface quality (scratches, dents, and ridges with a depth not exceeding 0.25 of the maximum allowable) is checked in general in all packages.

If the test results for at least one of these parameters turn out to be unsatisfactory, then a series of tests is performed - but already on a sample doubled.

How else is the wire checked according to GOST?

In addition, "bare" unfired wire produced in accordance with GOST 3282-74 can be tested for a number of other indicators, namely:

• on the ability to wind
• for tear resistance
• for stretching ability
• for resistance to repeated kinks

Features of wire packaging

For wire, the quality of which corresponds to the specified indicators, GOST defines the conditions for packaging and storage, of which the main requirements will be:

• long pieces of wire are wound into coils and tightly fixed;
• each bay should consist only of a single piece of wire;
• in the coil of wire, the ends should be located so as to be easily detected;
• coils formed from wire are tied up with at least 3 annealed wires;

Coils of wire of small cross sections must, in addition, be wrapped in paraffin-impregnated paper (if the cross section is less than 0.5 mm.) or polymer film (if the cross section is from 0.5 to 1 mm.)

When storing wire of large diameters, GOST allows (at the request of the customer) the use of anti-corrosion lubricating coatings based on technical oils I-50A, I-20A or ZhKB-1, NG-203.

Samples may be cut into an arbitrary number of segments depending on the test conditions.

4.6.1. Volumetric-gasometric method

The removal of the zinc coating is carried out by completely immersing the wire samples in the solution at ambient temperature until the gas evolution stops.

A coil (coil) of wire is evaluated by the arithmetic mean of the test results of at least two samples. The test is carried out separately for each sample in the following order:

a) take samples of the wire and measure the length specified for testing. Sampling is carried out not less than 0.5 m from one another;

b) degrease the wire samples in alcohol, benzene or gasoline and wipe with a clean cloth;

c) dissolve the zinc coating, completely trapping the hydrogen released in this case;

d) measure the volume of released hydrogen for each sample, summarize it and bring the arithmetic mean value to normal conditions (pressure 760 mm Hg, temperature 0 °C);

e) calculate the average surface density of zinc per 1 m 2 of the wire surface ( m) in grams, according to the formula

where V- arithmetic mean value of the volume of hydrogen under normal conditions, cm 3 ;

d- nominal diameter of the wire sample, mm;

l- sample length, mm.

The wire, the price of which is indicated above, is a metallurgy product that has the shape of a cord or thread. For its manufacture, through successively tapering holes, the process of drawing the source material is carried out: steel, copper, as well as other metals and alloys.

Our company sells wire made in accordance with GOST 3282-74. For its production, low-carbon steel is used. Applications:

• production of nails;
• production of linkage elements;
• production of building protections and other products.

Steel wire

The price depends on many factors, for example, at the moment there are two main production technologies: with heat treatment; without heat treatment. The coating is also of two types: galvanized and non-galvanized. Heat-treated non-galvanized wire can be distinguished by everyone: such a wire has a light color.

Products are also available in two degrees of production accuracy - normal accuracy and high accuracy. The diameter of the section lies in the range of 0.16 .. 10 mm, while the galvanized one has a diameter of 0.2 .. 6 mm. Steel wire with a cross section of 0.1 .. 7.5 mm from alloys with increased electrical resistance has found application in heating elements and resistors.

GOST allows a certain percentage of surface defects, such as local ripples, relatively small dents or shallow scratches. Such defects have a maximum allowable deviation threshold of 25 percent.

You can buy wire to choose from: in coils or in coils. To avoid entanglement of turns, it is required to observe the rows very accurately when winding, to do this without effort. One coil necessarily contains no more than one piece of wire, while the coil is limited to 3 coils.

Wire galvanized

Galvanized wire is one of the leading materials among metallurgy products, it is constantly required in everyday life and construction. Wherever it is not used: this is the manufacture of nails, cables, nets, all kinds of springs, wires, and reinforcement of reinforced concrete structures, and as fences. The list is endless!

The section can be either round or any other, for example, oval, square, etc. As mentioned earlier, the section diameter lies in the range of 0.2 .. 6 mm.

We also offer to buy welded galvanized mesh wholesale and retail.
