ASTM A588 Angle Steel Hot Rolled Corten Weathering Structural Angle Bar
Product Overview
ASTM A588 Angle Steel is a hot-rolled high-strength low alloy steel angle, it is an atmospheric corrosion resistant steel. Although more commonly identified with Corten weathering steel, when subjected to appropriate outdoor exposure, ASTM A588 angle steel forms a very stable protective rust patina that significantly retards additional surface rusting and extends maintenance cycles.
For its combination of structural strength, durability, and weathering good-performance, A588 Angle Steel is popular across a diverse range of uses including bridges, steel structures, industrial plants, infrastructure projects, outdoor decks, and architectural applications.
Royal Steel Group offers ASTM A588 weathering steel angle bars in broad range of sizes and lengths along with services of customized cutting, drilling, fabrication, inspection, packaging and shipping across the globe.

Main Features
1.Performance of the weathering steel: ASTM A588 is intended to form a protective patina when exposed to the atmosphere that provides superior resistance to atmospheric corrosion when compared to normal carbon steel.
2.High Structural Strength: The high-strength, low alloy nature of this steel part makes it capable of supporting heavy loads and is ideal for industrial applications.
3.Hot-Rolled Manufacturing: Hot-rolling ensures a uniform structure with good dimensional tolerance and with good suitability for further processing and utilization.
4.Less Maintenance: In some suitable outdoor conditions, the patina formed naturally in outdoor might even reduce the need of over-coating or maintenance treatment of the surface.
5.Multipurpose Structural Shape: The L-shape is an effective support and reinforcement for structural elements such as framing, beams, brackets, towers and much more.
6.Custom Processing: Cutting, drilling, welding, machining and other processing on the basis of customer's drawings and project description.
ASTM A588 Weathering Steel Material
ASTM A588 is a high strength low alloy (HSLA) steel which has been designed for use in structural applications where a higher level of corrosion resistance is required.
The alloying elements of A588 allow a protective surface layer to be formed under suitable atmospheric exposure. What happens over time is the original hot-rolled surface transforms to a typical brown or rust colored patina that offers both function and aesthetics.
The weathering action is most efficient in atmosphere of frequent wetting and drying and sufficient exposure.
MAIN APPLICATION
ASTM Angle Steel Service is employed in many structural and industrial applications, such as warehouses and manufacturers because of its superior strength, high weldability and dependable quality.
