Angle Bar

Angle Bar — Structural Steel Solutions

Angle bars (also known as Angle Steel / L-Shaped Steel / Equal & Unequal Angles) are structural steel sections with an L-shaped cross-section, widely used in building structures, metal frames, machinery manufacturing, photovoltaic brackets, ship construction, and various reinforcement projects.

They are typically made of carbon steel, stainless steel, or alloy steel, formed through hot rolling, cold rolling, or extrusion, and possess excellent strength, durability, structural stability, and processability.

As a long-term supplier in the industry, our Angle Bar products strictly comply with international standards such as ASTM, EN, GB, JIS, and DIN. We offer various specifications including Equal Angle / Unequal Angle / Stainless Steel Angle / Hot Rolled Angle Bar / Galvanized Angle Bar to meet the structural needs of different projects.

Angle Bar Features

Hastelloy® is a trademarked family of nickel-based superalloys developed by Haynes International. These alloys are engineered to resist highly aggressive chemical media, such as: Hydrochloric acid, Sulfuric acid, Ferric chloride, Sodium hypochlorite, Acetic & phosphoric acids.

Its superior thermal stability, stress corrosion cracking resistance, and pitting resistance make it ideal for extreme conditions where stainless steel or lower alloys fail.

Frequently Asked Questions
1. What is angle bar steel?+
Angle bar (or angle steel) is an L-shaped structural steel section produced through hot rolling, cold forming, or extrusion for construction and fabrication.
2. What industries commonly use angle bars?+
Widely used in building frames, towers, machinery structures, shipbuilding, bridges, and solar mounting systems.
3. What's the difference between equal and unequal angle bars?+
Equal angles have both legs of identical width, while unequal angles have legs of different widths for specialized structural applications.
4. What grades of angle bar are available?+
Common grades include carbon steel (Q235, Q345, A36), stainless steel (304, 316), and galvanized options for corrosion protection.
5. What are the typical size and thickness ranges?+
Angle bars range from 20×20 mm to 250×150 mm with thicknesses from 3 to 20 mm, with custom sizes available.
6. How do angle bars resist corrosion?+
Carbon steel angles can be galvanized (hot-dip zinc coated) or painted, while stainless steel variants provide inherent corrosion resistance.
7. What are the standard product forms and lengths?+
They're supplied in straight lengths (6m, 9m, 12m) and can be cut, drilled, and welded to specifications.
8. How easily can angle bars be welded and fabricated?+
They're highly weldable with standard processes (MIG, TIG, SMAW) and easily cut, drilled, and bent for custom applications.
9. Why is angle bar preferred for structural applications?+
Its efficient L-shape provides high strength-to-weight ratio, cost-effectiveness, and excellent load distribution in frames and supports.
10. How do I choose the right angle bar for my project?+
Select based on required load capacity, span distance, corrosion environment, code standards (ASTM, EN, GB), and budget constraints.
