Angle Steel – Complete Product Detailed Description
1. Product Overview
Angle steel, also known as angle iron, is a hot-rolled structural steel with L-shaped cross-section. It is divided into equal angle steel and unequal angle steel. With stable structure, high rigidity, excellent bending resistance, easy cutting, welding and installation, angle steel is one of the most widely used profile steels in global construction, steel structure engineering, machinery manufacturing and support frame projects.
Our angle steel is manufactured under standard rolling technology with precise dimension tolerance, smooth surface, straight angle and stable mechanical performance. All products are strictly inspected and widely exported to Africa, Central Asia, Southeast Asia and European countries.
2. Main Product Types
2.1 Equal Angle Steel
Both sides with the same width, the most common type for building frames, supporting structures and general steel fabrication. Full sizes in stock, large demand for overseas infrastructure projects.
2.2 Unequal Angle Steel
Different side widths, specially used for mechanical equipment, vehicle structures, bridge accessories and special engineering supports.
2.3 Galvanized Angle Steel
Hot-dip galvanized angle steel features strong anti-corrosion and rust-proof performance, suitable for outdoor structures, coastal engineering, power towers, guardrails and long-service-life municipal projects.
