Rigang black steel wire，It's widely used in construction or daily use as binding material. Besides, Mainly used in construction, mining, chemical, welded mesh, welded hangers, and then processing. Soft annealed wire, increase flexibility, doing construction tie wire, and has good steel banding.

Rigang Steel wire rod(s) is also called wire rod, which usually refers to small-diameter round steel in a coil. The diameter of the wire rod is in the range of 5-19mm (usually 6-9mm), and the lower limit is the minimum size of the hot-rolled steel section. There are many varieties of wire rods. Low carbon steel wire rods in carbon steel wire rod(s) are commonly called soft wires, and medium and high carbon steel wire rods are commonly called hard wires. Wire rods are mainly used as blanks for wire drawing, and can also be directly used as building materials and processed into mechanical parts.

Shandong Rigang Supply Chain Management Co.,Ltd. Prestressed steel wire is a high-strength steel, widely used in construction, bridges, tunnels, water conservancy projects and other fields. It has excellent mechanical properties and durability, and can effectively improve the bearing capacity and seismic performance of structures.
   The material of the prestressed steel wire is mainly high-strength steel wire, and steel wires such as SWRH82B and SWRH77B are usually used. These steel wires have the characteristics of high strength, high toughness, high durability, etc., can withstand large tensile and bending forces, and also have good corrosion resistance and fatigue resistance.
   The manufacturing process of prestressed steel wire mainly includes drawing, steel wire stranding, prestressing processing and other links. During the drawing process, the steel wire is drawn and annealed multiple times to make it meet the requirements of high strength and high toughness. In the wire stranding process, multiple steel wires are twisted into one prestressed steel wire to improve its bearing capacity and seismic performance. During the prestressing process, the prestressed steel wire is tensioned to a certain level of prestressing, so that it generates compressive stress in the structure, thereby improving the bearing capacity and seismic performance of the structure.

Shandong Rigang Supply Chain Management Co.,Ltd. Galvanized wire production process: It is processed by high-quality low-carbon steel wire rod, and the high-quality low-carbon steel is processed by drawing forming, pickling and derusting, high-temperature annealing, hot-dip galvanizing and cooling.
Galvanized wire characteristics: Galvanized iron wire has good toughness and elasticity, and the highest amount of zinc can reach 300 grams per square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Galvanized wire application: The products are widely used in various fields such as construction, handicrafts, weaving wire mesh, highway guardrails, product packaging and daily civilian use.
Galvanized wire is further divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire), which are distinguished as follows:
Hot-dip galvanizing is dip-plating in a heated and melted zinc solution. The production speed is fast, and the coating is thick but uneven. The minimum thickness allowed by the market is 45 microns, and the maximum thickness can reach more than 300 microns. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can last for decades in outdoor environments.
Cold galvanizing (electrogalvanizing) is to gradually coat the metal surface with zinc through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, and the thickness is thin, usually only 3-15 microns. The appearance is bright and the corrosion resistance is poor. It usually rusts in a few months.
Compared with hot-dip galvanizing, the production cost of electro-galvanizing is lower.

Shandong Rigang Supply Chain Management Co.,Ltd.  Metal sheet stretched mesh also refers to steel sheet stretched mesh, metal punching and shearing mesh. The stretched metal net refers to the metal plate net with different image holes formed by punching, shearing and stretching the metal plate. Common materials are steel plate, aluminum plate, stainless steel plate, brass expanded mesh, nickel expanded mesh, etc.

Shandong Rigang Supply Chain Management Co.,Ltd. Punching mesh/Perforated mesh refers to punching holes of different shapes on the same material. Common raw materials for perforated mesh include cold-rolled steel coils, stainless steel, galvanized steel coils, aluminum coils, copper coils, etc. Perforated mesh is suitable for environmental noise control, sound-absorbing panels around buildings, generator rooms, etc., and can also be used as speaker grilles.
The perforated net has a lot of loss in the production process, and the production process is complicated, mainly because it has a lot of hole-like structures, but this variety of shapes adds a colorful visual impact to the perforated net. Make the decoration effect of the punching net more obvious. At the same time, the perforated mesh has good air permeability and a wider range of use.
Specification of punching mesh plate: aperture 0.2-20mm, plate thickness 0.25-20mm
Iron plate punching mesh is divided by thickness: 1, thin plate, 2, medium plate, 3, thick plate, 4, extra thick plate

Shandong Rigang Supply Chain Management Co.,Ltd.The material of the metal woven mesh filter is made of metal wire woven mesh. The materials include carbon steel wire, stainless steel wire, aluminum wire, copper wire, etc. According to different weaving methods, the metal woven mesh is divided into two types: square hole mesh and dense pattern mesh. types. Dense netting can be divided into smooth grain and reverse grain. The square mesh woven by ordinary methods is generally used for coarse-effect filters; the dense mesh woven by inverted weave has high precision, good filtering effect, and high strength, but the porosity is small and the fluid resistance is relatively large.
