Steel Channel S235JR
Introduction to Steel Channel S235JR
Steel channel S235JR is a cornerstone material in modern construction and industrial applications.
As a non-alloy structural steel grade compliant with the European standard EN 10025, S235JR combines versatility, durability, and cost-effectiveness.
This product is widely recognized for its excellent weldability, machinability, and adaptability to dynamic loads, making it a go-to choice for engineers, architects, and fabricators worldwide.
| Height | 40mm to 400mm |
|---|---|
| Flange Width | 20mm to 100mm |
| Thickness | 3mm to 20mm |
| Length | 6m to 12m (custom lengths available) |
-
Cold bending performance
Good plasticity and toughness make it easy to cut, drill, cold bend and other processing, meeting the design requirements of complex structures.
-
Low carbon content
This significantly reduces the sensitivity of cold cracks during welding, simplifies welding process requirements, and greatly reduces welding costs and technical barriers.
-
High cost performance
While meeting the needs of a wide range of structural applications, S235JR has significant procurement cost advantages over higher grade steels (such as S355).
Mechanical properties
Yield Strength (ReH): ≥235 MPa. This is the critical stress value at which the material begins to undergo significant plastic deformation, and is a key indicator in structural design to prevent excessive deformation or failure. The yield strength of 235MPa ensures the stability and safety of the component under conventional loads.
Tensile Strength (Rm): 360 - 510 MPa. The maximum stress that a material can withstand before breaking reflects the overall strength and toughness reserve of the material. The wide range of S235JR indicates its good processing adaptability.
Elongation (A5): ≥26% (thickness t ≤ 40mm). Excellent ductility means that the material can absorb a lot of energy before breaking and has good plastic deformation ability, which is essential for bearing impact loads, preventing brittle fractures, and avoiding cracking during cold bending.
Surface treatment: adapt to different environmental requirements
To meet the corrosion resistance and appearance requirements of different application environments, we can provide channel steel S235JR with a variety of surface states:
Hot-rolled black state (Black): The surface state of steel after hot rolling and natural cooling, with a layer of dark blue iron oxide scale (Mill Scale). This is the most economical and common delivery state, suitable for subsequent sandblasting, painting or in a dry indoor environment.
Sand Blasted: The surface oxide scale and rust are removed by high-speed abrasive spraying, revealing the original color of the metal and increasing the surface roughness. It significantly improves the adhesion of subsequent coatings (such as paint and galvanizing) and is an ideal pretreatment state before painting.
Hot Dip Galvanized (Hot Dip Galvanized - HDG): The cleaned steel is immersed in molten zinc liquid to form a dense zinc-iron alloy coating. It provides excellent long-term corrosion protection, especially suitable for corrosive environments such as outdoor, humid, and industrial atmospheres, greatly extending the life of the structure and reducing maintenance costs.
Application
Construction field: Steel channel commonly used in beams, columns, supports and other components in building structures, such as frame structures for building houses, support systems for industrial plants, substructures of bridges, etc., which can bear the weight of buildings and various loads.
Mechanical manufacturing: Channel beam can be used as frames, brackets and other components of mechanical equipment, such as machine tool beds, crane bridges, and brackets for conveying equipment, etc., to provide stable support and structural foundation for mechanical equipment.
Vehicle manufacturing: In the production of vehicles, U shaped steel channel can be used to manufacture support structures for frames and carriages, etc., which helps to reduce the weight of the vehicle while ensuring the strength and safety of the vehicle.
