3. Corrosion Resistance In environments where moisture is a concern, such as outdoor applications or regions with high humidity, it’s crucial to choose screws that are coated or made from materials resistant to corrosion. Galvanized or stainless steel options are available and can greatly extend the lifespan of the fastening.
Conclusion
One of the key benefits of self-drilling screws is their ability to create precise and secure connections without the need for pre-drilled holes. This is particularly useful in applications where access to the back of the material is limited or where traditional drilling methods are impractical. Self-drilling screws are commonly used in the construction of steel and metal structures, as well as in the installation of roofing and cladding systems.
1. The diameter of the raw material and the thickness of the diameter are directly affected;
In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized process, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well.
4, when the greenhouse special electric galvanized shaft wire from the well and winding to the roll, be sure to clean up the well fluid, mud sand and other things stuck on the wire, and also coated with protective oil.
Some raw materials in the production of unstable processing, the wire itself will exist burr, surface small pits and other local defects. Galvanized steel in galvanized, generally should pay attention to the galvanized layer protection time of galvanized wire, and the thickness of galvanized layer has a great relationship. Generally speaking, when the main gas is relatively dry and used indoors, the galvanized layer thickness of galvanized wires is only 6-12μm, and under relatively harsh conditions, the galvanized layer thickness of galvanized wires needs 20μm, and can be predicted to reach 50μm.
1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it should also be reasonable for post-treatment to avoid affecting its use effect. Of course, when the black iron wire is galvanized, the thickness of the galvanized layer should be ensured, so that the possibility of rust can be reduced. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
Wire mesh first welding after galvanized is through the end of welding and then the company to produce wire mesh wire mesh steel mesh construction mesh, floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
