1. A brushed finish creates a matte, silky texture on the surface of stainless steel, offering high wear resistance and a more upscale visual effect. The surface texture can be categorized into four types: straight lines, random lines, wavy lines, and spiral lines. Straight lines are formed through mechanical friction, while random lines are achieved through an irregular oscillating grinding process.
2. The surface is matte; upon close inspection, you can see fine, thread-like textures, but these are not perceptible to the touch. It is more wear-resistant than regular glossy stainless steel and appears more sophisticated.
3. The brushing process reduces the thickness of the stainless steel sheet to some extent (generally by 0.1~0.2mm). Additionally, due to the high levels of oil and sweat secreted by human hands, brushed stainless steel sheets will show noticeable fingerprints with frequent handling and require regular cleaning.
4. Hot-rolled surfaces (NO.1) are characterized by a "rough, silvery-white, matte industrial finish, possibly with rolling marks." Therefore, in outdoor landscaping projects, the visible surface requires brushing. Cold-rolled surfaces (2B) are characterized by a "smooth, straight surface," so brushing is not necessary. If electroplating is required, brushing should be performed before electroplating.

II. Classification of Brushed Textures
1. Straight Brushed Texture. This is usually achieved by mechanically rubbing the stainless steel surface to obtain a straight texture. The brushing process eliminates scratches on the stainless steel raw material surface and also provides a good decorative effect. This texture also includes long and short brushed textures, as it is achieved by using a scouring pad or stainless steel brush to brush the surface of the sheet in straight or short lines. Different brush diameters can be used to obtain textures of varying thicknesses.

2. Brushed Random Grain (Random Grain). From a distance, the surface texture appears as concentric rings; up close, it's an irregular, random pattern, created by the irregular up-and-down and left-and-right oscillation of a grinding head, followed by electroplating for color. This texture has a matte finish and requires high-quality manufacturing.

3. Brushed Wavy Grain. This is achieved by using the axial movement of the grinding rollers on a polishing or texturing machine, resulting in a wavy texture on the stainless steel surface.

4. Brushed Threaded Grain. This has a unique manufacturing process. A small motor with a circular felt attached to its shaft is fixed to a table at approximately a 60° angle to the edge. A sliding plate is then used to hold the stainless steel sheet, with a polyester film attached along its edge to limit the threading speed. This allows for the linear movement of the felt and the mop, creating threaded textures of uniform width on the stainless steel surface.
