We should know that construction screw steel is most afraid of rusting and corrosion. When we visit the steel market, we will see two ways to store the screw steel. One is to put it outdoors directly and expose it to the wind and sunshine; the other is to store it in a shed, where the rain can't reach it and the sun can't shine on it.
There are many important building materials in our life, which belong to the steel most. If the daily maintenance is not proper, the construction screw steel will be corroded.
1. Steel bars in atmospheric environment are affected by sunshine, wind and sand, rain and snow, frost and temperature and humidity changes throughout the year. Water and oxygen in the atmosphere are important factors causing corrosion of outdoor steel.
2. This is aimed at some coastal areas. There is a large amount of salt in the ocean atmosphere. The deposition of salt particles on the metal surface has moisture absorption and erosion, which aggravates the corrosion of metal surface. The more serious the corrosion of coastal steel is, the more serious it is.
3. Steel products in industrial areas and industrial gases contain SO2, NO2, H2S and other metal elements. These gases will be acidic when combined with rain in the earth and sky. If acid rain forms and corrodes metal facilities, construction threaded steel can not escape corrosion if it is stored improperly.
Steel is a large-scale object, and the price is expensive, steel dealers should take good protective measures, Tianjin Tiantaicheng Steel Company's threaded steel is new, specifications are complete, national standard steel is your first choice.
