Angle steel is a common building and structural material. It can be classified into many categories according to different standards, mainly including:
Classification by edge shape:
Equal-leg angle steel: The lengths of the two sides are equal, usually used for load-bearing structures.
Unequal-leg angle steel: The lengths of the two sides are unequal, used for structures that require a specific force direction.
Classification by production process:
Hot-rolled angle steel: Produced by hot rolling process, with good mechanical properties and processing properties.
Cold-bent angle steel: Formed by cold bending, usually used for thinner materials, suitable for light structures.
Classification by material:
Carbon steel angle steel: The most common material with good strength and toughness.
Stainless steel angle steel: Strong corrosion resistance, suitable for humid or chemically corrosive environments.
Alloy steel angle steel: Contains other alloy elements and has specific properties such as high strength or high temperature resistance.
Classification by surface treatment:
Hot-dip galvanized angle steel: The surface is galvanized and has good corrosion resistance.
Spray-coated angle steel: The surface is sprayed with a protective layer to increase beauty and durability.
Classification by use:
Architectural angle steel: used for building structures, such as frames and supports.
Mechanical angle steel: used for the support and connection of mechanical equipment.
Different types of angle steel are suitable for different engineering needs. Choosing the right angle steel according to the specific application can ensure the safety and stability of the structure.
