Steel sheets or low-carbon steel sheets are one of the most used products in industries. These consist of high ductility, very good weldability, and ease to be machining. These sheets have high utility and can be easily used in construction, automotive, and other fabrication services.
Carbon steel has been one of the most used materials in industrialisation for many years. Different industries such as shipbuilding, automotive and construction industries have widely used steel sheet because of its favourable physical and mechanical properties.
Composition and Properties
Chemical composition | Mechanical properties |
---|---|
Steel sheet usually contains up to 0. 25% carbon and small quantities of manganese, silicon and other materials. This composition results in its well-known properties:

Types and Grades of Steel Sheets
Hot Rolled vs cold rolled steel sheets
Hot-rolled and cold-rolled steel sheets serve different purposes:
- Hot rolled sheets: Coated and produced at high temperatures, they are relatively cheaper and suitable for structural components.
- Cold rolled sheets: Rolled at room temperature they provide a smooth surface finish as well as improved precision, making them ideal for applications requiring precise tolerances.
Various Grades and Specific Uses in Industry
Different grades of steel sheets cater to specific needs:
- S355JR: S355JR is widely used in areas related to engineering structures. Its excellent weldability and impact resistance make it highly suited for building construction and bridges. Moreover, S355JR is frequently utilised in the production of large machinery and equipment because of its strong mechanical qualities and high strength.
- S355J2: S355J2 has better impact resistance. It is a good option for structures and specific uses that are exposed to different weather conditions outside the house, especially in colder regions It is frequently employed in the building of wind towers, offshore platforms, and other buildings exposed to severe weather. A higher level of toughness in S355J2 further makes it capable of withstanding regular usage, and dynamic load stresses.
Grade | Application | Key Characteristics |
---|---|---|
S355JR | Construction, heavy machinery | Good weldability, impact resistance |
S355J2 | Offshore platforms, wind towers | Improved low-temperature impact resistance |
ASTM A36 | Buildings, bridges, machinery | Excellent welding properties |
EN 10025 S275JR | Frames, supports, general engineering | Good machinability |
JIS G3101 SS400 | Ships, bridges, buildings | High strength, good weldability |
BS4360 Gr43A | Structural applications | High strength, good weldability |
Benefits of Steel Sheets
Cost-effectiveness and affordability | Ease of fabrication and machinability | Corrosion resistance and longevity with proper treatment |
---|---|---|
Steel sheet is more economical when compared to the other types of steel. It is affordable and offers good value and this makes it ideal for projects that are huge and have some strict budgets. | These sheets are very ideal for cutting, bending and even welding exercises as well. Standard operations of fabrication such as drilling, cutting, and welding are easy and thus lessen the time and money used in production. | Even though steel sheet is more vulnerable to corrosion, methods such as galvanising are effective at increasing rust protection. Steel sheet can effectively serve its purpose for several years, and with proper treatment, these products have a long lifespan. |
Sizes and Thicknesses
Grades | Width | Length | Thickness |
---|---|---|---|
ASTM A36 | Up to 3000mm | Up to 9000mm | From 1.2mm |
EH36 | Up to 3000mm | Up to 9000mm | From 1.2mm |
EN 10025 S275JR | Up to 3000mm | Up to 9000mm | From 1.2mm |
EN 10025 S355JR/J0/J2 | Up to 3000mm | Up to 9000mm | From 1.2mm |
JIS G3101 SS400 | Up to 3000mm | Up to 9000mm | From 1.2mm |
BS4360 Gr43A | Up to 3000mm | Up to 9000mm | From 1.2mm |
Thickness variations and implications
Usually, thicknesses vary to meet the needs of various applications:
- Thin sheets: Used in the appliance and automobile sectors.
- Medium sheets: Perfect for applications in building and structural engineering.
- Thick sheets: Used to build ships and massive equipment.
