PERFORATED SHEET MARKING AND IDENTIFICATION
Perforated metal sheet is a practical, durable, and quite interesting material that looks aesthetically pleasing and has a wide range of applications. It is used in architecture and construction, in building and room decoration, in household applications, as well as in the production of practical furniture.
However, manufacturing a large batch of such sheets takes quite a bit of time. It is much more profitable to buy ready-made products. The company "BCmesh" sells high-quality sheets with perforation of various types, including artistic perforation. However, before ordering the product you need, you should correctly identify its type, for which it is worth learning to "read" the marking of perforated sheets.
Marking of Perforated Sheet
BASIC TYPES OF METAL SHEET PERFORATION
All perforated sheets are punched on a special machine, forming a series of holes of a predetermined shape on the metal. This allows you to obtain products with round, square, rectangular, and elongated holes. Sometimes you can order sheets with artistic cutouts with hexagons, flowers, and other perforations.
Naturally, each of these sheets has its own designation: R, Q, L, and so on, depending on the shape of the hole. Lowercase Latin letters typically denote the orientation of the cutouts on the sheet (offset, straight, or diagonal). In addition, the sheets also indicate the orientation of the hole, its diameter, and the distance between them.
Marking of Perforated Sheet
MARKING OF THE MOST COMMON TYPES OF PERFORATION:
Rv 3-5: round perforation, checkerboard arrangement, hole diameter 3 mm, hole center distance 5 mm;
Qg 5-8: square perforation, straight arrangement, square side 5×5 mm, hole center distance 8 mm;
Rg 3-5: round perforation, straight arrangement, hole diameter 3 mm, hole center distance 5 mm;
Qd 8-14: square perforation, diagonal arrangement, square side 8×8 mm, hole center distance 14 mm.
Perforation Marking
PERFORATED SHEET MARKING - A DETAILED BREAKDOWN
To make it clearer for you, let's visually examine how the marking of a perforated sheet is carried out. Let's take, for example, such a sheet - Rv-3.0-5.0-1×1000×2000. This means that you have a sheet with dimensions of 1000×2000 mm, thickness of 1 mm, with round holes and offset rows. The hole diameter is 3 mm and the spacing between them is 5 mm.
Where R - hole shape (in this case, round);
V - arrangement of cutouts (we have offset rows);
3.0 - cutout diameter;
5.0 - hole spacing.
Also, the sheet may indicate the state standard (GOST) under which it was manufactured. You can find special tables on the Internet to determine the marking of the sheet and order the material correctly.
Our company offers sheets of various sizes with different types of perforation, so you can order any suitable option wholesale or retail.
