Product Description
Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle. There are equilateral angle steel and unequal angle steel. Its specifications are expressed in millimeters of side width x side width x side thickness. The specifications of hot-rolled equilateral angle steel are 2#-20#.

1.What is an angle bar?
Angle bars are used to strengthen reinforced concrete and in-situ concrete constructions, where it is used as hard and firm steel reinforcement bars. They are used in floors and multi-storey building overhead covers, as well as reinforcement of roof covering. Hot-rolled angle bars are used for construction of bridges.
2.What is another name for an angle bar?
Steel angle, otherwise known as lintel, angle bar, angle iron or metal angle, is steel that's bent or rolled to form a 90 degree or L-shaped cross-section.
3.What are the 4 types of angles?
Angles are where two lines meet, or a way of measuring where two objects are relative to each other from a particular point of reference, like measuring the position of a star. There are four main types of angles: right angles, acute angles, obtuse angles, and straight angles.
4.What are the different types of angle bars?
Types of Angle Bars
Equal Leg Angle Bars.
Unequal Leg Angle Bars.
Rolled Angle Bars.
Extruded Angle Bars.
Galvanized Angle Bars.
Stainless Steel Angle Bars.
Structural Support.
Brackets and Supports.
5.Do angle bars need maintenance?
Keeping angle bars clean is crucial for preventing corrosion and ensuring optimal performance. Regularly remove dirt, dust, and debris that can accumulate on the surface. For angle bar sizes used outdoors or in industrial environments, this is especially important as contaminants can accelerate wear.
