Product Description
Angle steel, also known as L-shaped steel or angle steel, is a structural steel with right-angle bending. It consists of two long sides (legs) perpendicular to each other and one short side (base). Angles can vary in size, with different lengths, thicknesses, and dimensions to suit specific applications. Angles usually have equal length legs, but unequal leg sizes can also be found.
Production Process
The production process of angle steel consists of several steps:
1. Raw material preparation: The raw material used for angle steel is usually low carbon steel or mild steel. The blank is then heated and shaped into a suitable rectangular cross-section for the subsequent rolling process.
2. Rolling: Pass the prepared billet through a series of rolling mills to form the required L shape. The shape is achieved by applying pressure and compressing heated steel. The angle iron is gradually formed to the desired size and angle.
3. Cooling and straightening: Cool the angle steel after rolling to stabilize its structure and prevent warping. Goes through a straightening process to remove any distortion and ensure straight and accurate angles.
4. Surface treatment: Angle steel can be given various surface treatments to enhance its appearance and provide corrosion protection. Common treatments include painting, powder coating or galvanizing.
Material Specifications
Because of its economy and availability, angles are usually made of mild or mild steel. Material Specifications can vary, but some common ones include:
1. ASTM A36: This specification covers carbon structural steel shapes, including angles, commonly used for general purposes
It can be used for construction purposes due to its excellent weldability and machinability.
2. EN 10025-2 S235JR: This European standard specifies the technical delivery conditions for hot-rolled non-alloy structural steels, including angles. It is commonly used in structural applications and has good formability and welding properties.
3. JIS G3101 SS400: This Japanese standard specifies hot-rolled general structural steel, including angle steel, which is widely used in various applications due to its high strength and excellent weldability.

Classification
Angles can be classified according to several factors, including:
1. Equal and unequal angles: Angle steel can have legs of equal length, forming so-called equal angles. Alternatively, it can have unequal leg lengths, creating unequal angles. Classification depends on the specific size of the angle.
2. Dimensions and Dimensions: Angles come in various sizes and dimensions, specified by the length of the legs and the thickness of the base. For example, an angle with dimensions 50 x 50 x 5 mm means that the two legs measure 50 mm each and have a bottom thickness of 5 mm.
3. Bearing capacity: Angle steel can also be classified according to its bearing capacity. This classification takes into account factors such as angular dimensions, material strength, and structural design requirements.
Applications
It is mainly divided into two categories: equal side angle steel and unequal side angle steel, among which unequal side angle steel can be divided into unequal side thickness and unequal side thickness.Angle steel has a wide range of applications in various industries and sectors, including:
1. Structural support: Angle steel is commonly used as structural elements in construction and engineering projects. It provides support and stability to structures such as buildings, bridges, towers and frames. Angles are commonly used in beams, columns, trusses and bracing systems.
2. Fabrication and fabrication: Steel angles are widely used in the fabrication process to create frames and supports for machinery, equipment and conveyors. Its versatility makes it suitable for forming brackets, frames, reinforcements and shelves.
