Angle steel bar is a common structural steel profile with an L-shaped cross section. It is also called steel angle, angle iron, L angle bar, or L section steel. Because of its simple structure, good strength, easy processing, and convenient installation, angle steel is widely used in construction, steel structures, towers, frames, brackets, machinery, bridges, shelves, support systems, and general fabrication.
Angle steel can be divided into equal angle steel and unequal angle steel. Equal angle steel has two sides with the same width, while unequal angle steel has two sides with different widths. Customers can choose different sizes, thicknesses, steel grades, lengths, and surface treatments according to project requirements.
Henan GDD supplies hot rolled angle steel, galvanized angle steel, painted angle steel, and customized angle steel products. We support steel distributors, construction companies, steel structure factories, machinery manufacturers, tower projects, fabrication workshops, and global industrial buyers.

Angle steel is a structural steel profile formed into an L-shaped cross section. The two legs of the angle provide good support and reinforcement performance, making it suitable for both load-bearing and connecting applications.
In steel structure projects, angle steel is often used as bracing, supports, frames, connecting members, edge protection, and reinforcement components. In industrial fabrication, it can be cut, drilled, welded, bolted, punched, galvanized, or painted according to the final product design.
Angle steel is popular because it is easy to process, economical, strong, and suitable for many different construction and manufacturing applications.
Equal angle steel has two legs with the same width. It is widely used in steel frames, supports, brackets, shelves, machinery structures, towers, and general fabrication.
Unequal angle steel has two legs with different widths. It is suitable for structures that require different load distribution, special connection design, or customized reinforcement.
Galvanized angle steel is coated with zinc to improve corrosion resistance. It is commonly used in outdoor structures, power towers, fences, solar mounting systems, construction brackets, and humid environments.
Customized angle steel can be supplied according to drawings, size requirements, length, hole position, surface treatment, and project specifications.
| Grade | Standard | Feature | Common Application |
| Q235B | GB | Economical structural steel with good weldability | General construction and fabrication |
| Q355B | GB | Higher strength and good mechanical performance | Steel structures, bridges, heavy frames |
| SS400 | JIS | General structural steel | Construction, machinery, steel components |
| S235JR | EN | Common structural grade | Buildings, supports, brackets |
| S275JR | EN | Medium strength structural steel | Fabrication and structural projects |
| S355JR | EN | High-strength structural steel | Bridges, heavy-duty structures, industrial frames |
| ASTM A36 | ASTM | Common carbon structural steel | Construction, frames, supports |
| ASTM A572 Gr.50 | ASTM | High-strength low-alloy steel | Heavy structures and engineering projects |
Angle steel is one of the most widely used structural steel profiles in construction and industrial manufacturing.
| Application Area | Typical Use |
| Construction | Structural support, reinforcement, frames, brackets |
| Steel Structure | Bracing, columns, beams, connection members |
