Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

The barbed rope produced by the barbed rope factory adopts the way of winding in order to facilitate transportation, and the disk weight of the galvanized barbed rope is different according to the size.

3, hexagonal network customized weight, the greater the weight, the more sufficient the material.

Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.

Stainless steel blade barbed rope material is produced according to stainless steel plate and stainless steel wire, as a whole have achieved the purpose of high quality anticorrosion.

High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.

The advantages of hexagonal net to do jet hanging net, the first is that the processing speed is fast, the cost is low, and it is very good to roll out when it is open because of the edge. Common specifications: 12 cm x15 cm (11cm x11 cm) 11 cm x15 cm (10 cm x10 cm) 10 cm x12 cm (9 cm x9 cm) 9 cm x13 cm (9 cm x9 cm) 8 cm x10 cm (7 cm x7 cm) common wire: 1.3mm 1.4mm 1.5mm 1.6mm 1.7mm 1.8mm 2.0mm 2.3mm 2.5mm Commonly used materials: galvanized wire hot dip galvanized wire to wire drawn zinc aluminum alloy plastic coated wire stainless steel wire.
