The galvanized wire is made of high-quality low-carbon steel wire rod. It is made of high-quality low-carbon steel, which is processed by drawing, pickling and rust removal, high temperature annealing, hot-dip galvanizing and cooling. Galvanized wire is further divided into hot-dip galvanized wire and cold-galvanized wire (galvanized wire).we are galvanized hard drawn wire
and the best galvanized hard drawn wire
,you can know it.
Subject content and scope of application
This standard specifies the technical requirements, test methods and inspection rules for hot dip galvanizing of steel.
This standard is applicable to steel structures made of carbon structural steel, steel pipe assembly pipes, welded or welded pipe fittings, hot-dip galvanized layers of containers and batch-processed steel parts and similar products. The steel pipe is galvanized and anti-corrosive.
Galvanized wire can be divided according to its use:
The wire for building bundling is 22# (0.71mm), the price is low, its characteristics are flexible and not easy to break. It is one of the most ideal wire binding in the construction industry, mainly using low-zinc cold-plated wire. Mainly used low-zinc cold-plated wire.
Handicraft iron wire, using a special processing of a line, no broken ends, the amount of zinc on the uniform and bright, the general price is slightly more expensive.
The galvanized wire also includes the sprinkling line: the weight of each plate is about 100 kg-1000 kg per roll, which is mainly suitable for industrial, agricultural and animal husbandry.
Tensile strength and calculation method of galvanized wire
Wire cross-sectional area = square of diameter * 0.7854 mm2
Wire breaking force Newton (N) / cross-sectional area mm2 = strength MPa
Classification of galvanized wire
The classification of electroplated zinc wire is divided into large-volume electroplated zinc wire, medium-volume electrogalvanized wire, small-volume electrogalvanized wire, galvanized axial wire, and cut-off galvanized wire. The galvanized iron wire is packaged and transported according to the customer's requirements, and the finished product is in shape, weight and quantity.
Large rolls of galvanized wire can reach a weight of 1 ton, mainly used for export, requiring no breaks in the middle, a smooth use of a complete product of a joint; small rolls of galvanized wire as small as 0.5 kg, 1 kg per piece, Mainly used for building market lashing and handicraft production, but also for export.
The galvanized cut-off wire used in the construction market at home and abroad is also an advantage product of galvanized wire manufacturers. Hot-dip galvanizing is immersion plating in hot melted zinc solution. The production speed is hot galvanized wire. The coating is thick but uneven. The market allows low thickness of 45 microns and height of up to 300 microns. The color is darker, consumes more zinc metal, forms an infiltrated layer with the base metal, and has good corrosion resistance to hot-dip galvanized wire. The hot-dip galvanizing in an outdoor environment can be maintained for several decades.
