A325 fasteners are available in different grades, which dictate their yield and tensile strength. The most common grades include
The hot plating wire is made of low carbon steel wire rod, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
People who want to keep birds for the long term need to know how to choose the right cage and how to raise them scientifically. It’s all about the birds’ daily life and health. Only by knowing more about the various aspects of raising birds can they be raised healthy and lively, singing freely and suitable for viewing.
Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.
One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.
With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.
Factors affecting the corrosion resistance of galvanized wire: The corrosion resistance of galvanized wire is affected by many factors, mainly including the following aspects.
The hook mesh is a good material for flood control and flooding. Can also be used for arts and crafts manufacturing, mechanical equipment transport network mountain beautification network – high strength steel wire grid (hook mesh, diamond mesh) hook mesh mountain protection application principle, hook mesh interests, mesh uniform, flat, woven concise, hook woven, beautiful and generous, net, net width, wire diameter is thicker, not easy to corrosion, long life, strong usefulness.
Cooling can be in the groove close row of thin wall plastic pipe, through the flow of tap water for cooling, can also be used as a temperature control device titanium pipe. In the process of electroplating galvanized wire, it is necessary to stir the plating solution to obtain the composite coating with particles dispersing in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
Select cut silk first to ensure that the raw material of the silk is exactly the raw material you need, the raw material will be used well. Choose high straightness, so that the length of the truncation will be the same, will not show a lot of length difference, the length of the truncated wire is a very important element to choose the truncated wire.
