Stainless steel finishing
Complete Hermes program for finishing stainless steel sheets, coils and plates
Design and brightness are the priority in surface finishing. Different stainless steel surfaces are required by stainless steel finishers depending on applications and requirements. A distinction is made here between ground, brushed and duplex (ground and brushed) finishes.
The surface finish of cold and hot-rolled stainless steel sheets, coils and panels is usually applied in service centres, but in some cases directly at steelworks. The surface finish is usually created by dry grinding, but for certain applications, also using a coolant additive such as emulsion or oil. Wide belt and brush-grinding machines are used to achieve an ideal, even surface finish. These can be arranged both individually or as a combined unit (grinding/brushing) in one machine or as consecutive grinding stations with separate individual machines.

Decorate finishing with HERMESIT and MERCURIT longlife grinding belts
Decorative finishing with HERMESIT and MERCURIT longlife grinding belts
Die Hermes-Langzeitschleifbänder der HERMESIT- und MERCURIT-Produktfamilien haben eines gemeinsames - den dreidimensionalen Schleifkornaufbau, der sich einerseits aus durch mit Schleifkorn ummantelte Trägerkugeln („HERMESIT-Prinzip“) und für das typische „HERMESIT-Finish“ auf Edelstahloberflächen verantwortlich ist bzw. aus einem Schleifkorn-Agglomerataufbau („MERCURIT-Prinzip“) ergibt.
Benefits you will appreciate
Bei der Abarbeitung der HERMESIT-Trägerkugeln bzw. der MERCURIT-Schleifkornagglomerate kommt fortwährend neues Korn zum Einsatz und daraus resultieren Vorteile, die die Wirtschaftlichkeit und Prozesssicherheit Ihres Schleifprozesses signifikant verbessern werden:
- Consistant surface finish and roughness values on workpieces, throughout tool life
- 3 to 5 times the tool life improves economy compared to conventional grinding belts:
- Reduced grinding belt change times
- Reduced disposal costs for used grinding belts
- Lower grinding temperatures

Further decorative finish grinding belts with a paper backing or a cloth backing
Paper-backed decorative grinding belts
In metal grinding, paper grinding belts with particularly strong paper backings are used for surface grinding/finishing.
These stable backings are primarily beneficial with wide belts for dry grinding. Due to their oil resistance, paper grinding belts can be used even when oil is used as cooling lubricant
Abrasive belt with high-performance aluminum oxide abrasive grain and with a additional Procut coating for cool grinding to reduce the risc of sheet metal rejections when grinding thin sheets (thicknesses < 1 mm).
High-performance ceramic grain paper-backed grinding belt for high stock removal rates, low grinding temperatures and uniform surface pattern.
Abrasive belt with silicon carbide grain and with a with a good edge stability for producing everything form a brilliantly bright decorative finish to so-called "mirror-finish surfaces".
Cloth-backed decorative finish grinding belts
The applications for cloth grinding belts are similar to those of paper grinding belts. However, they are even more robust and in addition to dry grinding, can also be used for wet grinding (resistant to water, emulsion and oil).
High-performance and durable standard cloth-backed abrasive belt for producing the finest surfaces with a very even grinding pattern.
Extremely stable cloth-backed abrasive belt with silicon carbide abrasive grain for producing brilliant bright stainless steel surfaces.
Very heavy, stiff and high-performance cloth-backed abrasive belt with ceramic grain.
The faster way to the brush finish
The “replicated” brush finish with cork grinding belts
As required by the customer different surface qualities can be produced. In most cases cold-rolled 3D material is the basic material. Normally the used grit size changes the produced surface pattern.
Variations can be achieved by different abrasive grain types or different machine parameters as for example the feed or the cutting speed or the design of the contact rollers.
The benefits for you
- Homogeneous finish without defects, such as lines or shadows caused by variations in brush roller construction
- Second choice base material can be used for an excellent brush finish
- Improved productivity due to increased line speed (up to 80 m/min at coil-to-coil machines)
- No time lost in dressing or balancing web rollers
- Belts can be handled easier in comparison to rollers
- Only with cork grinding belts a duplo finish can be produced with a higher line speed
- Wide belts with only one joint, available up to 1.600 mm width
And so it works ...
Hermes cork grinding belts
Flexible particles of cork on the polishing belts allow “cushioned” grinding and produces a polishing effect. This allows the mirror-finish surfaces desired by many customers to be produced in stainless steel finishing.
Cork grinding belts can be used universally in dry and wet grinding (resistant to water, emulsion and oil).

The special finish with webrax non-woven web abrasives
The special finish with webrax non-woven roller and belts
3 good reasons for webrax non-woven web
webrax non-woven web is manufactured from high-quality, three-dimensional special fibre web. The abrasive grain is firmly anchored by a bond to make it correspondingly durable.
We supply the following variants for finishing stainless steel sheets, coils and panels:
Non-woven web rollers
- Non-woven web
- Non-woven web, high density
Non-woven web grinding belts
- Non-woven web, laminated on Xw-cloth (* Heavy, moderately flexible, waterproof cotton cloth)
- Non-woven web, reinforced with cloth
2. Type of grain
The abrasive webs for finishing stainless steel are available in the grit range 80 to 800.
Warning: The abrasive effect and the grain details quoted are not comparable with those of grinding papers and cloths: for the same grit size, webrax non-woven web abrasives generally grind finer. Aluminium oxide and silicon carbide are generally used as the grains.
The abrasive grain is firmly anchored to the synthetic fibres by resins. The resin bond allows use under both dry and wet conditions. Benefits you will appreciate.
webrax non-woven web rollers
webrax non-woven web flap rollers produce an ideal brushed finish. We make these products in four different densities: 1 = soft, 2 = medium, 3 = hard, 4 = very hard. The rollers are also available with additional impregnation to increase tool life.
webrax non-woven web rollers are supplied with a maximum external diameter of 450 mm and in widths up to 2.050 mm. Universal use in dry and wet grinding (resistant to water, emulsion and oil).
