rb The surface of the regular steel belt is lubricated. Reduce the friction resistance between the steel belts and between the steel belts and the packaged objects during packaging, so that the steel belts can be tightened to make the packaging more secure. The edges of the steel belts are smooth and have no edges and corners, so as to avoid scratching hands and scratches on the packaged objects during packaging.
The outside of the steel strip is packed with linen, and each package contains a coil or coil of steel strip (according to the specific model), and is bound with iron bars. The raw material is high-quality cold-rolled plate.
The plate surface is smooth, the zinc flowers are uniform, and the color is bright
Galvanized strip steel has anti-corrosion and strong tensile properties Fire-resistant type and other characteristics
The galvanized strip steel produced is beautiful, economical and durable
The galvanized layer has good adhesion to the steel plate, is rust-proof and durable, and does not fall off< br />
As a raw material for a series of building materials, such as light steel keels, galvanized pipes, fireproof rolling shutter doors, civil materials and other industries.

The effects of different galvanizing methods on strapping:
Heat Since galvanized strapping is produced on a hot-dip galvanizing line, it is continuously hot-dip into zinc solution through continuous annealing. The steel plate is heated and cooled in a short time, so its stamping performance is worse than that of the cold-rolled original plate.
Since electroplated galvanized strapping is not affected by temperature such as heating and cooling during the electroplating process, it has roughly the same stamping performance as the cold-rolled original plate. There is no fragile iron-zinc alloy layer in the galvanized layer. The ductility of the galvanized layer is good, but due to the pores on the surface and low strength, it is easy to scratch and is susceptible to contamination such as dry paint.
Causes of indoor corrosion:
The corrosion of the zinc layer of galvanized strapping results in the formation of white iron, which has a great impact on the physical and chemical properties of the strapping. Big impact. The reasons why the zinc layer of galvanized packing tape corrodes indoors:
, high indoor air humidity
, finished products are not dried and stored
, zinc There is a layer of water film condensed on the surface of the layer. When the moisture content in the air reaches % or is within the range of ~%, and the corrosion reaction is more violent. When the water temperature is as high as about ℃, it will corrode the zinc layer the fastest.
Stacking site requirements:
When stacking galvanized strapping straps, there should be no condensation on the surface
There should be no condensation on the surface in the warehouse. Maintain air circulation. The relative humidity of the air should not be within the range of % or ~%
. There should be no harmful gases and excessive dust when stacking galvanized packing tapes
