During the stainless steel polishing process, technicians may use various types of sandpaper, such as sanding belts, sanding rolls, and sanding loops. So, how is this process carried out step by step?
If you’re curious, check out the detailed guide below from LEKAR on how to polish stainless steel quickly, simply, and effectively using sandpaper.
1. Learn about sandpaper and its role in polishing stainless steel.
Sandpaper is a material composed of three layers: abrasive grains, adhesive, and a backing layer made of paper or cloth. Its main function is to abrade the surfaces of various materials such as wood, plastic, and metal.
To polish the surface of stainless steel, sandpaper is an essential material.
Currently, there are various types of sandpaper available in the market, such as sanding belts (sanding rolls, sanding sheets), sanding discs, and sanding belts. Each type is used for different polishing purposes, with its own unique functions and advantages.
In metal surface treatment in general, and stainless steel polishing in particular, sandpaper is an essential material. Users can apply sandpaper manually or combine it with specialized machines. Sandpaper not only helps clean, smooth, and flatten the surface of stainless steel after processing but also enhances its shine and aesthetics, thereby increasing the product’s value.
2. How to polish stainless steel with sandpaper simply
In the process of polishing stainless steel with sandpaper, the technician needs to follow specific technical steps to ensure the final product achieves the highest quality. Below are the 4 steps for polishing that you can refer to:
Step 1: Rough surface grinding
Rough grinding, also known as initial grinding, is performed to remove excess material and large burrs from the stainless steel surface. This step typically requires the support of specialized equipment, especially sanding machines.
Nowadays, various types of sandpaper are used for rough grinding. Among them, coarse-grit sandpaper, typically ranging from #60 to #120, is the most commonly used.

Step 2: First fine grinding
This fine grinding step continues to remove any remaining excess material left over from step 1. At this stage, finer-grit sandpaper should be used for a smoother finish.
Step 3: Second fine grinding
The technician proceeds with even finer sandpaper to further polish the surface. This step enhances the smoothness and brightness of the stainless steel, ensuring that all unnecessary surface details are removed.
Step 4: Finishing
In the final finishing step, sandpaper can be combined with other materials such as buffing cloths or non-woven wheels. Once completed, the stainless steel product will have a mirror-like, smooth, and flawless surface.
Sandpaper makes the stainless steel polishing process faster and more efficient.
3. Where to Buy Sanding Belts for Polishing?
Sanding belts are indispensable materials in the process of machining and treating metal surfaces. When used in combination with polishing machines, sanding belts not only help reduce manual labor but also ensure production progress, quality, and the refined aesthetics of finished products.
As a widely used abrasive material, sanding belts can be easily found at many hardware stores or specialized polishing accessory suppliers. However, to ensure you select the right and high-quality products, it is recommended to purchase only from trusted suppliers.
