- The strength, service life and hardness of positive and negative twisting rope are good. The tensile strength of steel wire is 1200N and that of iron wire is 350N. This service life is much longer than ordinary wire barbed rope.
The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.
- Galvanized wire to galvanized evenly, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface scum in the plating pot and other reasons will cause the accumulation of galvanized layer on the surface of galvanized wire, and efforts should be made to solve the problem.
- Steel mesh plastic sprayed: Coating is also we often speak of electrostatic powder spraying coating, it is to make plastic powder charged with static electricity generator, adsorption in the iron plate or other product appearance, and then through 180 ~ 220 ℃ baking, make powder agglomeration adhesion of metal or other objects, plastic product used for indoor use more boxes, paint film present flat or matte effect. Spray powder mainly acrylic powder, polyester powder and so on.
Because the coal resources are exposed on the surface of the open pit coal mine, it is more important to protect and prevent coal theft. The erection and use of barbed rope in these places are better than other products. The barbed rope factory recommends suitable barbed rope products to everyone.

Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.

The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.

1. Improved Stitch Quality Using a zigzag presser foot ensures that the zigzag stitches are uniform and even, preventing issues such as skipped stitches or uneven tension.
The characteristic feature of a zigzag sewing machine is its ability to create a zigzag stitch, which is produced by moving the needle from side to side in addition to its up-and-down motion. This unique pattern allows for stitching that is not only functional but also decorative. The width and length of the zigzag stitch can typically be adjusted, enabling a diverse range of applications from seam finishes to embroidery.

Features to Consider
1. Heavy-Duty Construction Sewing machines meant for leather should have a sturdy frame that can withstand the stress of thick materials. Machines made of metal as opposed to plastic components usually offer better durability and stability.
Not Suitable for Heavy Fabrics:
Not all leather projects require the same thickness of thread. Factors such as leather thickness, the type of stitch, and the intended use of the item play a significant role in determining the appropriate thread size. General recommendations suggest using heavier threads, typically around size 69 to 138, for thick leather like harness and luggage leather, while finer threads serve well for lighter-weight projects.
The material of lock stitch sewing machine needles is another factor to consider. Most needles are made from high-quality steel, often coated with chrome or nickel to enhance durability and reduce friction. These coatings enable smoother sewing, especially when working with dense or heavy materials. Using the right needle material can significantly impact the lifespan of both the needle and the sewing machine, as well as reduce the likelihood of needle breakage, hence preventing potentially costly machine repairs.
Commercial Upholstery
- Needle Positioning The ability to adjust needle positions can enhance the functionality and the types of projects that can be undertaken. Some machines offer various needle spacing options to accommodate different styles of sewing.
Sewists can utilize double needles for more than just knit fabrics. They are also effective for hemming, topstitching, and adding decorative accents to a variety of materials, including cotton, denim, and more. By opting for a double needle, you can introduce unique design elements, such as decorative stitches that can elevate the overall style of a garment.
