Mirror-polished stainless steel / High-gloss polished stainless steel

When it comes to high-gloss or mirror-polished stainless steel surfaces, mirrorINOX offers traditional and new, pioneering solutions for applications
in architecture, yacht- and shipbuilding, for the automotive and electrical industry, medical technologies, container- and silo-manufacturers, machinery and engineering, aerospace and many more.

Even for the most demanding art projects, mirrorINOX`s polished quality is selected by the artists and designers.

What is mirror polished stainless steel used for?

In principle, we differentiate between technical applications, which require for instance the lowest possible roughness (Ra value) of the requested surfaces.

Such properties play a major role especially in the container- and silo-manufacturing, mechanical engineering, food and medical technology, where adhesion
to the stainless steel surfaces has to be avoided by using material that bears a maximum of smoothness.

Other customers request certain reflectivity from the metal finish, for example in the lighting industry. A mirror finish best reflects their demands.

Another more and more popular use of the mirror-polished stainless steel sheets is found in architecture, shop-fitting, ship- and yacht-building, where the focus is very strongly set on an optically first-class result in terms of the visual quality of the stainless steel sheets.

Adding to its flawless appearance, more advantages are the low weight ratio compared to glass mirrors, the very good workability and, immensely important when used in public buildings or other highly frequented locations such as trains stations, airports and others, the properties of break-proof, fireproof and vandalism-proof protection.

Mirror-polished stainless steel of the highest quality

mirrorINOX is your ideal and competent partner for all polished stainless steel surfaces of the highest quality: High-gloss polished, mirror-polished and various other levels of surface treatment.

However, since the very common terms "high gloss polished" or "mirror polished" often do not provide a very clear definition of the product, mirrorINOX
defines its self-produced and distributed mirror-polished surfaces in several quality levels such as Mirror No. 7, Super Mirror No. 8, Marine Mirror No 9.
and Perfect Mirror No. 10®, in order to create more transparency for the customer when inquiring and more clarity when ordering the material. That way,
you choose your preferred mirror finish to your liking.

What is the best way to polish stainless steel? Here is how we go about it

During the mechanical polishing, the surface is removed by our polishing lines and the help of polishing agents to create a finish as flat, smooth and flawless
as possible. Only after that, the actual mirror polishing takes place.

Depending on the base material, base surface finish, various machine parameters and processes, different results (qualities) can be achieved. The measurable values such as roughness and gloss plus the visual impression and approval serve as the base of control.

Bead blasting stainless steel by mirrorINOX

In many fields of expertise, high-quality applications increasingly request a uniformly matt, very homogeneous surface, which should not only be non-directional
but also bear little to no reflectivity.

Such a decorative and functional surface is created by blasting onto metallic materials such as stainless steel, aluminum, and even non-ferrous metals like brass
or copper at a very high speed with glass beads or with alternative blasting media of various bead sizes.

Glass bead blasting stainless steel: What are the applications?

In general, these timelessly elegant and visually attractive, metallic surfaces are used in the fields of architecture, elevators, facades, shop-fitting, ship-, yacht-building and works of art. As such, bead blasted stainless steel has many applications within countless professional fields.

They can also be found in high-quality machinery and industrial engineering.

mirrorINOX uses stainless steel sheets with dimensions of max. 2,000 mm (width) max. 6,000 mm (length) and max. 30 mm (thickness) for its bead blasted finishes.

What is glass bead blasting?

The terms “glass bead blasting”, “bead blasting stainless steel” or “bead blasted stainless steel” commonly refer to the surface treatment of sheets or workpieces where blasting a media such as glass beads, ceramic beads or corundum beads hit the material.

The size and roughness of the blasting media, the pressure and the speed during the blasting process can be altered in order to achieve different results
in terms of visual effect, reflectivity and roughness. As such, bead blasting is a very flexible process at mirrorINOX, leading to high quality results.

Glass bead blasting vs. sand blasting: Different methods of blasting stainless steel

For the visually less demanding requirements of industrial and heavy industrial applications, material like stainless steel or other metals are requested very frequently, resulting in different blasting processes such as those using sand ("sand blasting") or metal beads (“shot peening”).

In stark contrast to these processes, the Injector / Venturi blasting line operated by mirrorINOX is perfectly suited for the production of the BEADS product line
with its particularly uniform, very homogeneous surfaces for the highest quality applications.

mirrorINOX is the choice to go for to bead blast your stainless steel surfaces –
here is what we can offer:

The mirrorINOX products of its bead blasting range are called BEADS.

The different variations of the BEADS finish are as follows:

PVD-coating / TiN-coating

The PVD / TiN-coating process is increasingly demanded by architects, product designers and a large number of other users.

Naturally, mirrorINOX being an expert when it comes to surface treatments, is focusing strongly on using this pvd process to predominantly coating stainless steel sheets and other having gained vast expertise with this technology.

The commonly used terms “PVD-coating”, “TiN-coating” or “titanium nitride coating” stand in principle for one and the same process and are used synonymously when it comes to coating of stainless sheets.

Stainless steel PVD-coating – the PVD-coating process explained

In contrast to alternative coatings, for example galvanic processes, PVD-coating / TiN-coating uses no toxic or environmentally harmful substances.

Additionally, the extremely thin layers of the coating are very natural in their metallic and lively appearance, which distinguishes them decisively from alternatives such as wet painting, powder coating or anodized finishes.

Therefore, the PVD-coating process clearly proves to be an excellent method to coat the substrates. By the vapor deposition, not only are physical and technical advantages created, such as an increase in hardness or improvement in corrosion resistance, but also an optically high-quality refinement of these substrates
is achieved when coated with the thinner layers.

In the case of stainless steel PVD, for example, the colored surface coatings obtained with the PVD technology do not only protect the substrate, but also create fascinating metallic and optically extremely attractive shades, which range from champagne, yellow gold and brass to rose gold and bronze to anthracite and black.

Those fascinating colours, in combination with various basic surfaces, give the stainless steel an exclusive appearance and create brilliant examples of applications in architecture and product design for both indoors and outdoors.

What is PVD?

PVD is the process of Physical Vapor Deposition. The PVD / TiN-coating of large areas (sheets) is carried out with the help of ARC evaporation,
in which the "target material" in the form of a solid is brought to evaporation by means of an arc so that it can later be applied to the sheet or workpiece.

By adapting suitable reactive gases, different temperatures and other machine parameters, the chemical combination of metal and non-metal achieves different colors on the surface of the sheets or workpieces.

PVD-coating or TiN-coating: What is the difference?

As mentioned earlier, the abbreviation PVD, which refers to the English term "Physical Vapor Deposition" and also the term “TiN”, the abbreviation which derives
from the chemical compound titanium nitride (a hard metallic material made of titanium and nitrogen, typically of a golden yellow color), both define the same process of physical vapor deposition, and denote the same group of vacuum-based coating processes or thin-layer technologies.

As such, we will gladly advise you about these and other technical details as well as the possibilities mirrorINOX is able to offer when it comes to the PVD process.
We promise to our utmost to not let you in the dark about the PVD services we offer to you as it is in our strong belief that transparency is a fundamental right
of any customer.
