Latest Industry News

The global structural steel sector maintains steady development in 2026, and angle steel remains one of the most widely used hot-rolled steel profiles in the construction and engineering fields. With the continuous advancement of global infrastructure renewal, new energy supporting projects, and industrial factory expansion, the market demand for high-quality angle steel keeps growing steadily.

At present, standardized size production, stable chemical composition, and excellent surface treatment have become the core competition points of steel suppliers. More overseas buyers tend to choose durable, cost-effective carbon structural angle steel, as well as hot-dip galvanized angle steel with strong anti-corrosion performance for outdoor and coastal engineering.

What is Angle Steel

Angle steel, also known as angle iron or triangular steel, is a L-shaped long steel profile formed by hot rolling or cold bending. It consists of two sides perpendicular to each other. Featuring simple structure, high mechanical strength, easy cutting, welding and installation, it is an indispensable basic building material and industrial metal accessory.

Classification of Angle Steel

1. Classified by Section Type

• Equal Leg Angle Steel
Two sides with the same width, complete specifications, the most widely used type. Commonly used for building frames, supports, fixed parts and general engineering.

• Unequal Leg Angle Steel
Two sides in different sizes, suitable for special stress structures, curtain wall engineering, mechanical equipment supports and special installation scenes.

2. Classified by Material Grade

• Q235 Carbon Steel Angle Steel
Low cost, good toughness and weldability, mainstream for civil construction and ordinary engineering.

• Q355 Low Alloy High Strength Angle Steel
Higher bearing capacity, suitable for bridges, power towers, large industrial equipment and heavy-load projects.

• Stainless Steel Angle Steel
304 / 316 grade, rust-proof and corrosion-resistant, applied in marine environment, chemical industry, food equipment and decoration projects.

3. Classified by Production Process

• Hot Rolled Angle Steel
Mature technology, high overall strength, stable performance, the mainstream product for engineering construction.

• Cold Bending Angle Steel
Precise size, smooth surface, light weight, mostly used for light steel structure and decorative engineering.

4. Classified by Surface Treatment

• Black Steel / Plain Surface Angle Steel
Original rolling surface, cost-effective, suitable for indoor concealed parts and secondary processing.

• Hot Dip Galvanized Angle Steel
Thick zinc layer, strong anti-rust and anti-corrosion, suitable for outdoor, humid, coastal and outdoor guardrail projects.

• Painted / Coated Angle Steel
Custom color coating, beautiful appearance, anti-oxidation, for decoration and landscape engineering.
