EN 10025 S235JR Flat Steel – CE Certified for European Construction Projects-1
Product Introduction
Flat steel is a type of steel product with a rectangular or flat cross-section, typically produced through hot rolling or cold rolling. Its width (10mm~300mm) is significantly greater than its thickness (3mm~60mm). Known for high strength and machinability, flat steel is widely used in construction, machinery manufacturing, automotive components, shipbuilding, and other industrial applications.

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. |

1.What are the key applications of carbon flat steel?
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.
