What is more specific
Roughly speaking, this is a piece of alloy, which can be an independent element. For example, a barn can be covered with a sheet of iron. But it is quite suitable as a raw material for the production of various products. For example, stamped body elements for cars are made from the same thin steel.
Main types
There are several of the most common. By type of finished products can be:
high-quality;
sheet;
pipe;
special (shaped).
Which happens depending on the production technology:
cold-rolled (first, a workpiece is formed by pickling, and then shaped by means of several shafts);
hot-rolled (the workpiece is formed due to the strong heating of the alloy or steel).
Depending on the metal:
black (cast iron);
non-ferrous (alloys);
stainless (not subject to corrosion).

Main parameters and pipe profiles
The classification is based on several criteria. They are divided depending on the diameter, size, material of manufacture, connection method, type of insulation, profile cross section.
Kinds
Steel. The advantages of these products include a long service life (about 25 years) and reliability, the disadvantages are huge weight, lack of resistance to corrosion. They are made galvanized, welded, cold and hot rolled, cold drawn, profiled.
Galvanized. They are able to tolerate various temperature extremes. Not subject to corrosive influences. At a cost, of course, much higher than usual, but, on the other hand, they are several times better in quality.
Copper. Pluses are durability (the service life reaches 100 years), resistance to corrosion and high temperatures. Cons - high price, low strength, difficult installation.
Cast iron. Depending on the strength, there are black, gray and spheroidal graphite. Reliable, corrosion-resistant, but not so strong and costly during installation work.
Metal-plastic - made of plastic and metal. By far the most popular on the market. They have many positive characteristics: price, quality, ease of installation. The disadvantages include poor resistance to temperature extremes.
In addition, according to the method of application, the pipes can be:
electrowelded;
water and gas pipelines;
casing;
seamless;
