  • What is a Zigzag Stitch?


  • The position of the needle as it enters and exits the leather is fundamental to achieving secure stitches. Ideally, you should hold the leather firmly but not excessively tight, as this can distort the material. When inserting the needle, aim to enter the leather at a 90-degree angle to maintain consistent stitch depth. This angle not only ensures a cleaner penetration but also helps create uniform spacing between stitches.

The diameter of steel wire can reach 2.0mm-4.0mm. The surface of steel wire is usually used for hot-dip galvanized maintenance. The thickness of galvanized maintenance layer can be made according to the needs of customers.

  • The production process is to roll the hot metal billet into 5mm thick steel, and then put it into the wire drawing device, draw into different diameters of the line and gradually reduce the aperture of the wire drawing disk. Production process through cooling, annealing, coating and other processing technology, and then made into a variety of different specifications of galvanized wire. Galvanized wire production because of simple process, wide application, early development. Galvanized wire or steel wire is a cold working product of steel wire, and the material used is generally low carbon steel or stainless steel.

  • The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.

  • (4) Stop the use of more than two strands of galvanized iron wire around the operation method.
