Types of grit finishes for stainless steel and other metal sheets:
- Grit polishing
- Brush polishing
- Satin grit polishing
- Hairline grit polishing
- Cross grit polishing, Etc.
When applying these mechanical surface treatment processes, various patterns and designs of polishing are achieved with the help of a variety of abrasive media, different machinery, and machinery parameters.
The desired finishing results are defined by the customer’s optical specifications, for example, in architecture and other design applications, in which details such as the reflections and the haptics of the surface play an extremely important role (e.g., building architecture, indoor and outdoor wall designs, escalators, balustrades, etc.).
Since inox steel sheets do not usually have a very attractive appearance and are often not sufficiently reproducible when they leave the mill or service center, STAINLESSINOX processes their surface with very high-quality grit-polishing standards to provide you with a satisfactory result.
Our stainless steel grit polishing offer
- Large selection of grit patterns and finishes from very fine to very coarse.
- Free-issue grit polishing, grit polishing of aluminium, brass, titanium, and other services on request
- Production according to customer specifications possible: Ra grinding and other special grinding types such as CROSS, perpendicular grit polishing, and others
- Values of each order and every sheet, such as gloss and roughness, are measured and recorded, thus ensuring maximum reproducibility.
- Grit polishing is also possible on both sides of the stainless steel plate (Front + Reverse)
Grit finishes on stainless steel: our grades and applications
STAINLESSINOX always offers you the optimal grit finish solution for stainless steel sheets or plates, such as SATIN finish sheets, whether it be small quantities of material or larger projects in the fields of:
- Architecture
- Elevators
- Escalators
- Shopfitting
- Exhibitions
- Yacht and shipbuilding
- Machinery engineering, Etc.
Our solutions are predominately based on stainless steel grades AISI 304 and AISI 316 for outdoor applications, particularly for façade construction, as well as using raw materials such as aluminium, titanium, or brass and also for grit-polished surfaces.
Other highly sought-after products are finishes with extremely low Ra values. These can go as far as high-gloss surfaces (Ra value <0.1), which are required for the most demanding industrial applications, for example in:
- Container and machine construction
- Pharmaceutical and food industry
- Cleanroom and medical technology
Here again, STAINLESSINOX meets the highest technical requirements for stainless steel surfaces and other types of metal.
How do we grit polish stainless steel?
STAINLESSINOX ‘s controlled and precisely recorded production is based on many years of experience in stainless steel grit polishing, measurement of the roughness depth and the gloss of the surface, and the professional assessment of the visual appearance.
In addition to that, we have sufficient production capacities to guarantee the fastest delivery service possible.
