The difference between angle steel and angle iron
Angle steel and angle iron are different names for the same material in many cases. They both refer to steel consisting of two perpendicular flanges, similar in shape to the letter "L".
Definition
Angle steel: The standard name is angle iron, which is a steel with an L-shaped cross section, widely used in construction, machinery manufacturing and other fields.
Angle iron: In some specific cases, metal angle iron can also be called steel angle iron, but in fact they refer to the same material.
Shape and structure
Cross-section shape: Whether it is metal angle or angle steel bars, its cross section is L-shaped, consisting of two perpendicular flanges.
Dimensions: According to the national standard GB/T 706-2016 "Hot-rolled steel", steel iron angle has a variety of specifications, including equal angle steel and unequal angle steel.
Equal angle steel: The width of the two flanges is equal. Unequal angle steel: The width of the two flanges is unequal.
Material and performance
Material: Steel metal angle usually uses carbon structural steel such as Q235 and Q345 or low-alloy high-strength structural steel.
Mechanical properties: Sheet metal angle has good bending resistance, good ductility, easy processing and welding, and is suitable for various structural parts. Depending on the material, the yield strength and tensile strength of structural angle are different.
Application areas
Building structure: Structural steel angle is used for beams, columns, support frames, stair handrails, etc. in buildings.
Mechanical equipment: Rolled steel angle is used for frames and brackets of mechanical equipment.
Bridge construction: Hot rolled steel angle is used for structural parts of bridges.
Others: such as cable trays, shelves, etc.
