12/26/2025

S235JR angle steel, produced in accordance with EN 10025, is one of the most commonly used structural steel materials in construction, manufacturing, and industrial projects. Known for its reliable mechanical properties, good weldability, and cost efficiency, S235JR angle steel is widely selected for both structural and fabrication purposes.

This article introduces the classification, application areas, and practical uses of S235JR angle steel, helping buyers, contractors, and distributors better understand where and how this material is applied.

How Is S235JR Angle Steel Classified?

S235JR angle steel can be categorized based on geometry and intended application. Understanding these classifications helps ensure correct material selection for different project requirements.

Classification by Shape

Equal Angle Steel

Equal angle steel features two legs of identical width and thickness, providing balanced strength and uniform load distribution. It is commonly used in steel frames, machinery structures, platforms, and equipment supports.

Unequal Angle Steel

Unequal angle steel has legs of different widths, making it suitable for applications with asymmetric loads. It is often applied in building reinforcement, customized steel structures, and support systems.

Classification by Application

Industrial Angle Steel

S235JR angle steel used in industrial environments offers stable strength, good toughness, and excellent weldability. Typical applications include machinery frames, steel structures, containers, and industrial equipment.

Construction Angle Steel

In construction projects, S235JR angle steel is widely used for wall corners, door and window frames, floor reinforcement, brackets, and auxiliary structural components. Dimensional accuracy and surface quality are key requirements.

Decorative and Fabrication Angle Steel

For furniture manufacturing, shelving systems, interior decoration, and metal fabrication, S235JR angle steel is often selected for its clean appearance and processing flexibility. Galvanized options are frequently used to improve corrosion resistance.

Common Applications of S235JR Angle Steel

Building and Infrastructure

S235JR angle steel is extensively used in building frames, stair structures, ventilation systems, cable supports, handrails, and safety barriers. It is often installed to connect beams and columns or reinforce concrete structures.

Machinery and Equipment Manufacturing

In mechanical and manufacturing sectors, angle steel plays an important role in machine bases, lifting equipment, transport frames, and load-bearing structures, offering stable mechanical performance.

Structural Support Systems

Galvanized S235JR angle steel is widely applied in steel frameworks, racks, beams, columns, and support systems where durability and corrosion resistance are required.

Furniture and Storage Systems

Angle steel is commonly used in the production of tables, chairs, bed frames, warehouse racks, and shelving units, providing strength, stability, and cost-effective fabrication.

Oil, Gas, and Chemical Industry

S235JR angle steel is used in pipe supports, platform structures, equipment frames, and storage facilities within petroleum, natural gas, and chemical processing industries.

Why Choose S235JR Angle Steel?

S235JR angle steel offers a practical balance between strength, weldability, and cost. It is suitable for a wide range of structural and non-critical load applications, making it a popular choice for international projects following European standards.
