Product Description

NO.4 Finish Stainless Steel Coil

1. Surface Treatment
The NO.4 finish, also known as satin finish or brushed finish, is achieved by mechanically polishing the stainless steel surface with abrasive belts or brushes. This process creates a uniform, dull appearance with fine parallel lines, imparting a smooth texture to the surface.

2. Appearance
The surface has a muted, matte appearance with a low level of reflectivity, characterized by fine, evenly distributed lines running in the same direction. It provides a contemporary and elegant aesthetic suitable for various applications.

3. Applications
NO.4 finish is commonly used in architectural and decorative applications where a refined, textured surface is desired, such as wall panels, elevator interiors, kitchen equipment, and decorative trim.

4. Material Specifications
Grades: 304,304L,303,302,301,430,201,202,316,316L
Thickness: Typically ranges from 0.3mm to 3mm, but can vary based on specific requirements.
Width: Commonly available in widths from 3.5mm to 1500mm.

304 Stainless Steel Sheet

304 is the most versatile and widely used of all stainless steels. Its chemical composition, mechanical properties, weldability and corrosion/oxidation resistance provide the best all-round performance stainless steel at relatively low cost. It also has excellent low-temperature properties and responds well to hardening by cold working. If the potential for intergranular corrosion in the heat-affected zone exists, 304L is recommended.

Mirror finish stainless steel sheet is also named mirror-polished stainless steel sheet, which is processed with a non-directional and high-gloss polished #8 finish to remove the scratches, grooves, or dents on the surface, which can make it like a super reflective mirror, and it doesn't need any finishing or coating material to assist the process.	The surface texture of brushed finish stainless steel sheet looks like straight hair, so it's also known as a hairline stainless steel sheet. The hairline grain is processed by applying the #4 finishing technique, which dully polishes with a metal bristle brush turning on a wheel or belt that moves in the same direction when polishing the metal surface, then use a medium non-woven abrasive belt to re-polish the surface with some greaseless compound make it more delicate.
Grand Metal has the ability to produce etched stainless steel sheet and other metal sheets with precise and long-lasting etched patterns. The exposed areas are etched by acid to remove a thin layer of metal, the surface becomes dull and matte, and the concealed areas are protected by the film and retain their original condition, the non-etch areas can be finished with some specified colors before or after the etching process.	PVD coated stainless steel sheet is one of the innovative types of powder coated metal sheets. PVD coating is a type of paint that is applied to the surface of the sheet, which is a mixture of polyester and fluorocarbon. PVD coated aluminum sheets are known to have excellent properties, including excellent weather resistance and rust resistance. These panels are suitable for a variety of building materials and can be custom-designed for the desired thickness, color, and shape.
