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. 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
Iron plate punching mesh is divided into: 1. Hot rolled steel plate, 2. Cold rolled steel plate material, 3. Stainless steel plate 302, 304, 316, 304L, 316L, 4. Aluminum plate, and 5. Copper 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.

Rigang Ductile iron pipe is a type of cast iron, an alloy of iron, carbon and silicon. Graphite in ductile iron exists in the form of spheroids. Generally, the size of graphite is grade 6-7. The quality requires that the spheroidization level of the cast pipe be controlled to grade 1-3 (spheroidization rate ≥80%). Therefore, the mechanical properties of the material itself The performance has been better improved, with the essence of iron and the performance of steel. The metallographic structure of the ductile iron pipe after annealing is ferrite plus a small amount of pearlite, and has good mechanical properties.
