1. What Is Angle Steel?

Angle steel, also known as angle bar, L-shaped steel, is a long strip steel with perpendicular two sides, divided into equal angle steel and unequal angle steel two main categories.

Equal angle steel means two legs have the same width; unequal angle steel has two different leg widths. It is widely used as basic structural component in all engineering industries due to stable mechanical performance and easy welding, cutting and processing.

2. Main Classification of Angle Steel

2.1 By Section Shape

1. Equal Angle Steel

Common specifications: 20×20mm, 30×30mm, 40×40mm, 50×50mm, 63×63mm, 70×70mm, 80×80mm, 100×100mm etc., different thickness from 3mm to 16mm.

2. Unequal Angle Steel

Typical sizes: 40×25, 50×32, 63×40, 70×45, 90×56, 100×63mm, suitable for asymmetric support structures.

2.2 By Surface Treatment

1. Black Pickled Angle Steel

Original hot rolled surface, low cost, used for indoor concealed steel frames without anti-rust demand.

2. Hot Dipped Galvanized Angle Steel

Immersed in molten zinc after pickling, thick zinc coating, excellent anti-corrosion, suitable for outdoor, coastal, humid environment. It can resist rain, seawater oxidation for decades.

3. Painted Angle Steel

Spray anti-rust paint on surface, short-term anti-corrosion, mainly used for temporary building supports.

2.3 By Production Standard

- Chinese Standard: GB/T 706 Hot rolled section steel standard

- American Standard: ASTM A36 Carbon structural angle steel

- European Standard: EN 10025 Structural steel angle bar

All our angle steel can produce according to customer’s required standard, full mill test certificate provided.

3. Chemical & Mechanical Performance

Our carbon angle steel adopts Q235B, Q355B as main raw material, stable chemical composition without harmful impurities.

- Q235B: Yield strength ≥235MPa, good plasticity, easy bending & welding, for civil construction, small support frame

- Q355B: Yield strength ≥355MPa, high bearing capacity, for large steel structure, bridge support, engineering bracket

4. Wide Application Scenarios of Angle Steel

1. Building Construction

Main material for house steel frame, wall keel, ceiling support, stair handrail bracket, warehouse rack base.

2. Bridge & Highway Engineering

Used as guardrail support, bridge auxiliary bracket, road sign fixing frame.

3. Machinery & Equipment Manufacturing

Machine base bracket, equipment fixing frame, transmission support frame.

4. Solar PV Bracket System

Hot galvanized angle steel is the top choice for ground solar brackets, corrosion resistant for outdoor long service.

5. Municipal & Water Conservancy Project

Street light support, pipeline fixing frame, dam auxiliary steel structure.

6. Shipping & Container Auxiliary Parts

Light load connecting bracket for ship deck and container auxiliary fixing.

6. Purchase Tips for Angle Steel

1. Confirm equal or unequal angle according to your project load demand.

2. Distinguish surface treatment: choose galvanized type if working outside or seaside area.

3. Clarify material grade: Q235B for light load, Q355B for heavy bearing structure.

4. Specify exact size (leg width × leg width × thickness) and required fixed length.

5. Confirm execution standard before mass order to avoid dimensional deviation.
