Angle Steel, Angle Bar, L Shape Steel

Angle Steel

Angle steel, commonly known as angle iron, is a long strip of steel with an L-shaped cross-section and two sides perpendicular to each other at 90°. Angle steel can be used alone as a load-bearing component or combined with other steel materials to form various supporting structures or connecting components. Angle steel has good weldability, plastic deformation capacity, and high mechanical strength, and is widely used in building structures and engineering structures, suitable for factory frames, bridges, transmission towers, and warehouse racking, among other fields.

Types of Angle Steel

Equal angle steel

Equal angle steel refers to angle steel with two legs of the same length. It is the most common type used in steel structures and fabrication projects.

Unequal Angle Steel

Unequal angle steel has two legs of different lengths, which allows engineers to design structures with more flexible load distribution.

Stainless steel angle steel

Stainless steel angle is a type of stainless steel profile with an L-shaped cross-section and two sides perpendicular to each other at 90°. It is usually made of stainless steel materials such as 304 stainless steel and 316 stainless steel, and has good corrosion resistance, strength and aesthetics.

Carbon steel angle steel

Carbon steel angle is a type of structural steel with an L-shaped cross-section and two sides perpendicular to each other at 90°. It is mainly made of rolled carbon structural steel, and common materials include Q235 carbon steel, Q345 carbon steel and ASTM A36 steel.

Galvanized Angle Steel
Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip zinc angle steel. Cold galvanizing coatings mainly use electrochemical principles to ensure full contact between zinc powder and steel, generating an electrode potential difference for corrosion protection. Hot-dip galvanized angle steel, also called hot-dip zinc angle steel, involves immersing rust-removed angle steel in molten zinc at around 500℃, causing a zinc layer to adhere to the surface of the angle steel, thus achieving the purpose of corrosion protection. It is suitable for various strong acid, alkali mist, and other highly corrosive environments. Cold galvanizing is used to protect metal from corrosion. For this purpose, zinc-filled coatings are used. These are applied to the surface to be protected using any coating method, and after drying, a zinc-filled coating is formed. The dried coating contains a zinc content (up to 95%). It is suitable for repair work (i.e., during repair work, only the damaged areas of the protected steel surface need to be repaired before recoating). Cold galvanizing is used for corrosion protection of various steel products and structures.
