Flexible Size and Stock Options
The 304 stainless steel sheet can be supplied in standard stock dimensions or manufactured according to customer requirements.
For cold-rolled sheets, common stock sizes include 1000 × 2000 mm, 1220 × 2440 mm, 1250 × 2500 mm, and 1500 × 3000 mm, with thicknesses generally ranging from 0.4 to 6.0 mm.
Hot-rolled sheets are commonly available in thicknesses from 3.0 to 16.0 mm, with dimensions such as 1250 × 2500 mm, 1500 × 3000 mm, 1500 × 6000 mm, 1800 × 6000 mm, and 2000 × 6000 mm.
Thicker sheets from 6.0 to 80 mm can also be customized according to the required width and length. Mirror, hairline, color-coated, and sandblasted sheets are available in customized dimensions as well.
Multiple Surface Finishes
Surface treatment is an important part of stainless steel sheet selection, particularly when appearance is a major consideration.
Available options include:
2B Surface
A commonly supplied cold-rolled stainless steel finish with a smooth, practical appearance, suitable for general fabrication and industrial applications.
BA Surface
Bright annealed stainless steel provides a brighter surface appearance and is suitable for applications where a cleaner visual finish is required.
8K and 6K Mirror Finish
Mirror-polished surfaces provide a highly reflective appearance for decorative and architectural applications.
No.4 Surface
The No.4 finish features a directional brushed appearance and is widely used for equipment, architectural elements, kitchen products, and interior decoration.
HL Hairline Finish
The hairline finish creates a continuous linear texture, offering a refined appearance for decorative panels and architectural applications.
Embossed and Perforated Surfaces
Embossing and perforation provide additional design and functional possibilities for architectural panels, decorative products, and specialized fabrication projects.
304 Stainless Steel Grade Equivalents
304 stainless steel is available under different designation systems depending on the applicable standard.
