Stainless Steel Channels
General information on stainless steel channels
Stainless steel channels are structural beams that are created from stainless steel, a type of steel that contains at least 10.5% chromium and is highly resistant to corrosion. These channels are often used in construction, manufacturing, and other structural applications where strength, durability, and corrosion resistance are important factors.
There are several different types of stainless steel channels, including standard channels, tapered channels, and miscellaneous channels. Standard channels are typically used for general structural purposes and have a U-shaped cross-section, while tapered channels are used where a slope is needed. Miscellaneous channels are a catch-all category that includes a variety of custom shapes and sizes.
Manufacture of stainless steel channels
A widely used stainless steel material for the production of stainless steel channels are 304 or 316. Stainless steel channels can be either cold or hot rolled, laser welded or edged.
In the cold or hot rolling of channels, stainless steel flat material is rolled either at room temperature or forming temperatures of at least 1,100° C and passed through rollers to produce the U-shaped profile cross-section. Compared to hot rolling, cold rolling results in a higher degree of precision, higher strength and metal hardness and a finer surface than hot rolling, but is more costly because it requires more rolling passes. The rolling process creates a fillet with a pronounced radius at the transitions to the profile legs.
For laser-welded channels, three strips of strip steel or, in the case of thicker material, sheet metal are used as the starting material. The contact surfaces between the stainless steel strips are welded directly together by laser welding. The resulting weld seams are hardly noticeable and can be reworked so that they are almost invisible. With this process, sharp-edged stainless steel channels can be produced with tight tolerances.
If channels are made of stainless steel materials with the appropriate corrosion and acid resistance, they can also be used untreated outdoors, in humid conditions or even in aggressive industrial environments. However, surface treatments such as grinding or polishing are often applied to make the material smoother and thus even more corrosion-resistant and easy to clean, or to emphasise the noble appearance of the material.
Where are stainless steel channels used?
Stainless steel channels are ideal for areas where high corrosion resistance or particularly high-quality surfaces are desired. Due to their stability, they can serve as structural elements depending on the profile thickness, for example as beams, support elements or frame profiles, or be used to make racks, housings, cladding or gutters, as edging or edge protection and as running or guide rails.
Overall, stainless steel channels are a versatile and durable material that is widely used in a variety of applications due to its strength, corrosion resistance, and aesthetic appeal.
Stainless steel channels are used in a variety of applications, including:
- Construction: Stainless steel channels can be used in the construction of buildings, bridges, and other structures as a support for beams or as a protective barrier.
- Manufacturing: Stainless steel channels are often used in the manufacturing of various products, such as machinery, equipment, and vehicles.
- Food processing: Stainless steel channels are frequently used in the food processing industry due to their ability to resist corrosion and their ease of cleaning.
- Chemical processing: Stainless steel channels are resistant to corrosion and are often used in the chemical processing industry for piping and storage tanks.
- Marine environments: Stainless steel channels are often used in marine environments, such as on ships and offshore platforms.
- Architectural design: Stainless steel channels can be used in architectural design for their aesthetic appeal and durability.
- Other industries: Stainless steel channels may also be used in other industries, such as the automotive, aerospace, and pharmaceutical industries.
