What is No.3 Stainless Steel Surface Finish? Properties and Applications
What is No.3 stainless steel surface finish? Stainless steel is a material widely used in many fields, from industrial production to architectural applications, standing out with its durability and aesthetic appearance. One of the most important factors determining the performance and application area of this material is its surface finish. Karametal Steel offers high-standard stainless steel products in both cold-rolled (No.2B) and hot-rolled (No.1) surface finishes.
Cold-rolled stainless steels are characterized by their annealed and matte surfaces. These materials, shaped through coarse grinding processes, are frequently preferred especially in interior and exterior building decorations, kitchen equipment, and household applications. Their matte surface prevents glare, providing a more natural and simple appearance in architectural designs. Additionally, the level of surface roughness can be adjusted through sandblasting, offering users a wide range of options both aesthetically and functionally.
Its unidirectional textured structure gives stainless steel a characteristic appearance. This texture enhances resistance to scratches. Since it reflects less light compared to polished surfaces, it is particularly preferred in modern and minimalist interior designs. Such surfaces are also defined as 1G or 2G stainless steel finish quality and are known for maintaining visual uniformity.
- Cold-rolled stainless steels with No.2B finish are generally produced in thicknesses ranging from 0.50 mm to 6.00 mm. These products are used in applications requiring high precision, such as industrial kitchen equipment, white goods manufacturing, and decorative claddings. Due to their smooth, clean, and aesthetic surfaces, they are highly suitable for processing, painting, or coating.
- Hot-rolled stainless steels with No.1 finish are produced in thicknesses ranging from 4.00 mm to 50.00 mm. These products are used in heavy industrial applications requiring high strength, as well as in construction and machinery sectors. Although the surface becomes rougher as a result of the hot rolling process, durability is increased. Therefore, No.1 surface finish is especially preferred for structural steel elements, tanks, boilers, and large-scale industrial projects.
Karametal Steel manufactures in its modern technology-equipped facilities without compromising on quality and precision in both production methods. By providing technical support in material selection, it ensures the most suitable surface finish is chosen for each project.
In conclusion, whether you are looking for an aesthetic appearance in architectural decoration or durability in heavy industrial applications, Karametal Steel’s No.1 and No.2B surface finishes offer solutions suitable for every need. With their matte, durable, and controlled texture, 1G / 2G finished stainless steels combine quality, aesthetics, and performance under one roof.
