Since the discussion has begun on the topic of the names of steel products, let's develop it!
So let's get it right. Rolled metal products are usually marked with special codes of letters and numbers.
Fittings with code A3, or column I-beam, is used in construction. It is made of steel 25G2S and 35GS. It has diameters of 6, 8, 12 - 22 mm and more.
The first digit in the name indicates the diameter of the product, and the next - the class of steel used. Then follows the designation: is the product unmeasured (“Nemer”) or measured. The type of product is indicated at the very beginning: “Period” - grooved products, “Circle” - smooth.
Decking.
In the name code, the first digit is the thickness of the sheet, the second is the width, the third is the length, all in mm.
Letters in the title
C - wall fencing
H - for flooring
HC - for fencing and flooring.
The last digit indicates the height of the profile.
The corner.
The product names contain numbers: side x side x thickness. These values are shown in millimeters. It is important to remember that corners can be not only equal, but also different-sexed.
Channel.
In the labeling of these products, you should pay attention to the letters: “C” - special, “L” or “E” - having parallel sides of the shelves of the light / economical series, “P” - parallel shelves, “U” - the inner faces of the shelves have a slope. If the name contains one number, then it indicates the height of the product. If three - then this is its height, width and thickness of the profile.
I-beam.
The designations "U", "B", "W", "D", "K" are assigned to beams with internal shelves having parallel faces, and "M" if they are with a slope. The numbers indicate the height of the I-beam, the width of the shelf, as well as the thickness of the profile.
Wire.
Slab.
In general, complement, discuss ...
Let's replenish our dictionary together! Personally, I recently learned some names.
Good luck to all!
