Steel is the primary material used for supports and hangers; common options include carbon steels such as Q235B and Q345B, as well as stainless steels like 304 and 316. While carbon steel is cost-effective and suitable for most environments, stainless steel or hot-dip galvanized steel offers greater durability in humid or highly corrosive settings, such as chemical plants or coastal areas.
Anti-corrosion treatment is crucial for extending the service life of supports and hangers. In addition to hot-dip galvanizing, methods such as applying anti-corrosion paint or epoxy resin coatings can be used. For instance, supports and hangers in food processing plants often need to meet hygiene standards, making stainless steel and specialized coatings the preferred choices.
