Over the years, various industries have sought durable and beautiful decorative materials to meet the growing pursuit of aesthetics. From aerospace to submarine infrastructure, stainless steel has become the preferred decorative material due to its excellent corrosion resistance and aesthetics.


Stainless steel has become one of the most popular decorative materials widely used in various industries. You can see it in buildings, landmarks, and even medical equipment. Stainless steel has achieved present status because of its excellent machinability. This article will explore the fundamentals of stainless steel and its surface finish process.

What is Stainless Steel

Stainless steel is an alloy resistant to rusting and corrosion. It originated in 1798 and has been applied to architecture since the early 1900s. And its elements include C, Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.

Cr is the main characteristic that determines stainless steel corrosion resistance. As the indispensable content, Chromium should be at least 10.5%. It will form a coat of self-passivation (oxide) film on the surface to prevent corrosion. The oxide film also can prevent rust from diffusing to maintain its aesthetic and achieve it usable for a long time.

Stainless steel has become one of the most practical alloys with its high weather ability, weldability, plasticity, and corrosion. As a multipurpose material, you can see it from primary products to architectural aesthetics.

The most commonly used type of stainless steel includes the 201, 304, 304L, 316, 316L, and 430 worldwide. You can choose it according to the environment. When used for city architecture, 304 or 304L is the best performance and cost choice.

If used in harsh environments, such as marine or high-temperature industries, SUS 316, SUS 316L, duplex stainless steel, or ferrite stainless steel is the best choice. Because they have higher corrosion resistance and weather ability.

As decorative materials, stainless steel supports various processing, including but not limited to brushed, polished, colored, and embossed. Different situations need different stainless steel finishes. An embossed finish may be chosen in high-traffic areas for its higher scratch resistance.

Types of Stainless Steel Finishes

Raw steel has a rough and dull surface. A decorative plate often requires higher aesthetics. Certain specific industries will require high corrosion resistance of steel. At this time, stainless steel finishing processing came into being.

Every manufacturing process of stainless steel produces a surface texture. We can transform raw steel into high-value products with further surface finishing techniques. Some common stainless steel surface finishing techniques include polishing, brushing, and blasting.

Mirror Finish Stainless Steel

Mirror finish is achieved by buffing and polishing the surface of stainless steel until the roughness is less than 0.8um. The wear marks are barely visible, which can get a sparkling, mirror-like finish. By mirror polishing, the luminosity of stainless steel can be maximized.

During processing, the smoothness of the surface and the flatness of materials can be adjusted.

The most significant characteristic of the Mirror(8K) finish stainless steel is its brightness, like a mirror. Except for visual appeal, the smooth surface can avoid dirt or bacteria, which is the popular stainless steel finish in architectural decoration.

With the highest brilliance, aesthetic and visual expansion of space, Mirror finish stainless steel is often applied to product frames, interior wall decoration, landmark buildings, fittings, bathroom mirrors, and ornaments.

The stainless steel thickness and the project details will affect the quality of the mirror finishes. So, you must confirm the specification as per your project requirements. If you can’t make a selection, please consult with TOPSON and obtain professional suggestions from our engineers.

Bead Blasted Stainless Steel

Bead blasting is one type of shot-blasting technology. It is a finish that utilizes the bead blaster shooting the bead-shaped media to the stainless steel surface at high pressure. Generally, this process maintains the metallic properties of stainless steel and leaves a smooth, shiny, and cleaner matte surface.

Due to its excellent surface finish, bead blasted stainless steel sheet is suitable for various industries, as well as construction, elevators, ornaments, ceiling, and perimeters.

The bead blasted finish depends on the blast media size. It could be adjusted as required for the project. Therefore, confirming the effect and application with your manufacturer before the specification is necessary.

Water Ripple Stainless Steel

A water ripple sheet is a decorative stainless steel that utilizes embossing to form a water texture on the surface. The size of the rippling could be adjusted as required for the project. The most commonly sought classification of sizes is tiny, medium, and large.

When used in decorating, it can reflect the surrounding scenery in a subtle way and brings spaces a dazzling, vivid, and luxurious ambiance.

Water Ripple has stronger corrosion resistance and a higher aesthetic. It can be applied to decorating the ceiling, elevator door, hallways, architectural wall cladding, etc. Generally, 304 stainless and 316 stainless steel are available to fabricate water ripple.

Combined with the Mirror(8K), hairline finish, or PVD coating finish, this technique enables to create of unevenness on both sides of the surface (respectively).

Hairline Stainless Steel (#4 Finish Stainless Steel Sheet)

Hairline finish is one metalworking type of brushed finishes. It forms a matte surface on the stainless steel panel with long, continuous and uni-directional grind marks. It is referred to #4 finish stainless steel sheet. But it is more reflective than a No. 4 polish.

Adjusting the grinding technology can control the texture size to create different brushed effects, like D-HL and Scratch HL. TOPSON will help you achieve whatever brushed finish you need with our strong metalworking.

As one of the classics for stainless steel, hairline finish stainless steel is suitable for interior and exterior products, such as elevator door, escalator cladding, architectural decoration, kitchen cabinet and so on.

Brushed / Cross-brushed Stainless Steel

Cross hairline or cross brushed, is a stainless steel brushed finish with a pattern of intersecting lines at a 45-degree angle.

The grain size can be adjusted by controlling grinding times. Prior to specification, confirm the texture direction with your metalworking fabricator based on project requirements.

Cross hairline is the most commonly sought decorative finish of stainless steel. Due to its excellent scratch resistance, it is suitable for high-traffic areas, like construction cladding, elevator handrails, ornaments, and perimeters.

Vibration Stainless Steel

Unlike hairline finish, vibration stainless steel is a low reflective brushed finish with short, non-directional arch-like grind marks. It utilizes vibratory polishing technology, and the vibratory action causes the media to rub against the workpieces to generate the desired result.

Vibration is the second most commonly sought stainless steel finish as a decorative material. With higher corrosion resistance and scratch resistance, it suits for panels and handrails.

Another advantage of vibration stainless steel, it supports further processes, such as PVD colored or plating, for higher aesthetics and scratch resistance. If so, it may be the best choice for exterior products in high-traffic areas, like architectural walls, luxury doors, advertising boxes, outdoor screens, etc.
