EN 10025 S235JR Flat Steel – CE Certified for European Construction Projects
Definition of Flat Steel
Flat steel is a type of steel product featuring a rectangular cross - section with slightly rounded edges. It is produced through processes such as hot rolling, cold rolling, or cold drawing. With defined width and thickness, its shape endows it with high versatility, making it a staple in a wide array of industries.
Materials and Standards

Standards |
|
Carbon Steel |
Offers good strength and plasticity within a certain carbon content range. Cost - effective, suitable for general structures and mechanical parts. [Insert a picture of carbon steel flat steel here, labeled "Carbon Steel Flat Steel"] |
In the United States, ASTM A36 is a common standard for carbon steel flat bars, which specifies mechanical properties like yield strength (min. 36 ksi) and tensile strength (58 - 80 ksi). In Europe, EN 10025 - 2:2004 covers non - alloy structural steels, with grades such as S235JR having specific chemical composition and mechanical property requirements. |
|
Low Alloy Steel |
Enhanced strength, toughness, and corrosion resistance compared to carbon steel due to the addition of a small amount of alloying elements. Ideal for applications with elevated performance demands. [Insert a picture of low alloy steel flat steel here, labeled "Low Alloy Steel Flat Steel"] |
ASTM A572 in the US is a well - known standard for low - alloy high - strength columbium - vanadium structural steel. Grades like A572 Grade 50 have a minimum yield strength of 50 ksi. In the international context, ISO 4950 - 1:2018 defines technical delivery conditions for hot - rolled flat products of high - yield - strength steels for cold forming, applicable to low alloy steels used in various industries. |
|
Stainless Steel |
Exhibits outstanding corrosion resistance, maintaining performance in humid, acidic, and alkaline environments. Widely used in food, medical, and decoration sectors. [Insert a picture of stainless steel flat steel here, labeled "Stainless Steel Flat Steel"] |
ASTM A240 is a major standard for stainless steel in the US. For example, 304 stainless steel (type 304 in ASTM A240) has a minimum chromium content of 18% and nickel content of 8%, ensuring excellent corrosion resistance. In Europe, EN 10088 - 2:2005 deals with stainless steels, specifying properties for different grades used in various applications. |

Application
Construction Industry: Flat steel plays a crucial role in building structures. In steel - framed buildings, it is used to fabricate beams, columns, and trusses, providing essential strength and stability to support the entire structure.
Mechanical Manufacturing: It serves as the primary raw material for manufacturing various mechanical parts such as brackets, machine bases, and shafts. Its consistent shape and reliable mechanical properties guarantee the quality and performance of mechanical products.
Automotive Industry: Flat steel is utilized in automotive manufacturing. It is involved in the production of car frames, suspension systems, and some interior components. Its high strength and formability meet the strict requirements of automotive safety and design.
Decoration and Artwork: Stainless steel flat steel, in particular, is highly sought - after in decoration and artwork creation. It can be used to create decorative handrails, fences, sculptures, and other artworks, combining aesthetic appeal with long - lasting durability.
Surface Treatment, Packaging and Transportation
Surface treatment: including bare material (Bare), galvanized (Galvanized), painted (Painted), etc. Galvanizing can significantly improve corrosion resistance.
Packing method: usually bundled into rolls or loaded into containers (20/40 feet), suitable for sea or land transportation needs.

1. How to choose the right material for flat steel?
For general - purpose structures where cost - effectiveness is a priority, carbon steel is an optimal choice. In scenarios where higher strength and enhanced corrosion resistance are needed, such as industrial equipment in harsh environments, low alloy steel is more appropriate. When corrosion resistance is of paramount importance, like in food - processing plants or coastal areas, stainless steel flat steel should be selected.
2.Can I get non - standard dimensions of flat steel?
Absolutely. We are equipped to provide non - standard dimensions of flat steel according to your specific requirements. Please reach out to our sales team with detailed size information, and we will strive to meet your needs.
3. What is the delivery time for flat steel orders?
For standard products in stock, the delivery time is typically within 7 working days. For customized products or large - quantity orders, the delivery time may vary depending on the production process and order volume. Generally, it ranges from 10 - 20 working days. We will communicate the precise delivery time to you once your order is received.
4. How to ensure the quality of flat steel?
We operate a rigorous quality control system. All raw materials are sourced from reliable suppliers and undergo strict inspection prior to production. During the production process, multiple quality checks are carried out to ensure that the flat steel complies with relevant national and international standards. Each batch of products is accompanied by a quality inspection report.
5.Do you offer surface treatment options for flat steel?
Yes, we do. We provide several surface treatment options for flat steel, including galvanization to enhance corrosion resistance, painting for decorative and protective purposes, and polishing to achieve a smooth and shiny finish, especially for stainless steel flat steel used in decorative applications.
