Ask the factory to provide the corresponding quality inspection report before packing. Cold drawing is a kind of material often used in our life, especially in the construction of buildings. Cold wire drawing is used more in building materials, cold wire drawing testing standards are also different. The strength of cold wire drawing is high, and it can be used in many aspects. Where plasticity is not required, only strength is required, such steel can be used.

1 3 8 drywall screwsThe large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.

- Heavy hexagonal mesh is made of low carbon steel wire galvanized large wire braided, the tensile strength of steel wire is not less than 38kg/m2, the diameter of steel wire can reach 2.0mm-3.2mm, the surface of steel wire is usually hot galvanized protection, galvanized amount can reach 500g/m2.
- Nemator roller cage is connected by nemator connecting clasp with longitudinal tension bar fixed on the support, and the connection between longitudinal tension bar and support is selected. The 2.5mm cold-drawn galvanized steel wire is wound 2 times and then tightened and fixed. The bracket is set on the column and the cross side of the protective fence with a span of 3m. Other spans are only set on the upper part of the column, and the bracket and the protective fence are connected with the bracket hoop.
- Before wall plastering, the wall column is connected to the gap construction wire mesh, which can play a certain strengthening and heat preservation effect. The mesh is hung on the interface surface of different grassroots, and the length of each side should meet the requirements of 100mm, so as to prevent shrinkage and cracking caused by different grassroots. Mesh wire diameter can also determine the effect and efficiency of construction, mesh fine laid up convenient soft, high construction efficiency; Of national standard can assure quality, but laid respect is inferior to fine construction fast.

After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.
