The following are some features and applications of hot galvanized hot rolled flat steel: 1. Corrosion resistance: hot dip galvanized layer can effectively protect flat steel from corrosion, suitable for humid, corrosive environment and outdoor use. 2. Strength and toughness: hot rolled flat steel has good strength and toughness, which can meet the requirements of general structure and mechanical parts. 3. Appearance quality: The surface of the flat steel after hot dip galvanizing is smooth, the zinc layer is uniform, and the appearance quality is good. 4. Widely used: often used in building structures, manufacturing Bridges, steel structure components, guardrail, shelves and so on. In the selection of hot galvanized hot rolled flat steel, it is necessary to consider the size of flat steel, thickness, zinc layer thickness and other parameters to meet the specific application needs. In addition, during installation and use, attention should be paid to protecting the hot-dip galvanized layer to avoid scratches and damage.
