Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.

3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh is attributed to a hook mesh, it is the selection of galvanized wire, hot dip galvanized wire as raw materials, woven through the hook mesh crimping truncated.

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. So how long can stainless steel blade thorn rope be used?

2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.

Hexagonal guardrail net custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, is prone to fracture, lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail net and extend the service life of the product.

The fence effect of the barbed wire installation can be recognized by the majority of customers, its advantages are as follows: First of all, for some of the original protective device barbed wire because of the convenience of installation, the installation process is very simple, only need to fix the barbed wire column, and then gradually install the barbed wire according to the hook on the barbed wire column.

The whole country is cooling down on a massive scale. People suddenly feel that winter is coming. In much of the north, the collection of central heating and heating has also begun. People who do not have central heating or do not want to use traditional heating choose air heating. As heating equipment enters the peak season, building network sales are also gradually increasing.

Pet cage You can choose a pet cage that you like or find suitable. It is recommended that you buy a metal cage, with a metal tray at the bottom, of course, the better is stainless steel, plastic can also be, but the plastic tray is very easy to be bitten by pets and damage, plastic tray is also easy to be pet uric acid corrosion, and plastic products are also low, not durable. So pet cages are usually made of metal. This will prevent the pet from entering the house and causing damage, while also providing it with maintenance and not getting sick from running around and touching dirty things.
