The anodising process: Chemical conversion for maximum resistance
The anodising process (short for electrolytic oxidation of aluminium) is a surface technology process in which a protective oxide layer is created on aluminium through anodic oxidation. In contrast to galvanic processes, the protective layer is not applied, but is created by converting the top metal layer into an oxide or hydroxide. This creates a 5 to 25 micrometre thin layer that protects the material from corrosion - in comparison, the natural oxide layer of aluminium is only a few nanometres thick. The layer thickness varies depending on the application:
- 5-10 micrometres: Suitable for indoor use.
- 15-20 micrometres: Ideal for outdoor applications.
- Up to 25 micrometres: For extreme conditions such as in industrial areas or on seashores.
This finish makes the aluminium resistant to corrosion, abrasion and mechanical stress. The oxide layer also offers protection against dirt thanks to its closed structure and is easy to clean.
Advantages of anodised ladders compared to untreated aluminium
Anodised aluminium ladders offer decisive advantages over untreated ladders in terms of functionality, durability and aesthetics.
One major advantage is the excellent corrosion protection. The oxide layer created during the anodising process permanently protects the aluminium surface from moisture, salty air and chemical substances. This property makes anodised conductors particularly suitable for use in damp environments or in areas with aggressive environmental influences, such as near the coast or in industrial production facilities.
Another advantage is the increased surface hardness. Anodised aluminium is significantly more resistant to mechanical stresses such as scratches or abrasion. The robustness of anodised rails proves to be a significant added value, particularly in everyday working life, for example on construction sites or in industry, where ladders are frequently moved or subjected to loads. This not only extends the service life of the ladder, but also minimises maintenance costs.
The grip and feel of anodised ladders make a decisive contribution to user-friendliness. The smooth surface is pleasant to the touch and remains non-slip even under difficult conditions such as wet or dirty conditions. This not only increases ease of use, but also work safety - a key aspect in any professional working environment.
Anodised aluminium ladders also score points for their appealing aesthetics. The matt or shiny surface has a high-quality and professional appearance, which makes it particularly suitable for use in prestigious environments such as exhibition stand construction, shop fitting or modern offices. The visual design can also be adapted to individual requirements through colour variations.
An often overlooked advantage is the cleanliness of anodised aluminium surfaces. Due to the closed and smooth structure of the anodised layer, the surface is less susceptible to soiling such as dust, oil or grease. Such substances adhere less easily, which makes cleaning much easier. The ladder remains visually neat and hygienic, especially with frequent use. Another advantage in terms of cleanliness concerns the hands of the user. In contrast to untreated aluminium, which often leaves black residue after intensive use, the hands of anodised ladders remain clean. This makes them ideal for use in hygienically sensitive areas such as pharmacies, food shops or hospitals. Anodised ladders are also the perfect choice in environments where packaging or surfaces need to remain clean - for example in retail.
Finally, the anodising process is characterised by its remarkable sustainability. It is an environmentally friendly process that does not produce any toxic residues. The aluminium remains fully recyclable, which not only offers ecological benefits but also meets the requirements of modern, sustainable production processes. Anodised ladders are therefore a sensible investment for anyone who values durable, safe, hygienic and visually appealing work equipment.
Anodised KRAUSE ladders: perfect for demanding applications
With its anodised products, KRAUSE offers a selection of ladders and steps that combine high quality, durability and functionality. The models are specially designed for applications where cleanliness, stability and comfort are paramount.
Securo and SePro S step ladders
The Securo and SePro S step ladders with single-sided access combine sophisticated safety features with a high level of convenience. Both models have ergonomically shaped safety rails with integrated storage areas that provide space for tools, cables and buckets. The anodised uprights are easy to clean and prevent hands from getting dirty - ideal for hygienically demanding environments.
The Securo features a 250 mm deep aluminium platform with slip-resistant inserts and six riveted step/rail connections for high stability. The 125 mm deep, slip-resistant safety steps ensure safe ascent and descent, while the slip-resistant safety foot caps provide a firm footing.
The SePro S is the high-end model and also offers a high-strength, flanged step/rail connection and a 260 mm deep aluminium platform with barleycorn profiling for maximum slip resistance. The 80 mm deep V-steps with anti-slip profile increase comfort, while sturdy metal articulated joints ensure safety and durability.
Step double ladder SePro D
The SePro D can be accessed from both sides and is ideal for work areas that require flexible access. It is characterised by a 250 mm deep top platform that provides additional storage space. The high-strength, flanged step/railn connection ensures a particularly robust construction, while the large foot caps guarantee stability and floor protection. The anodised uprights make cleaning easier and prevent soiling, which also makes the SePro D interesting for sensitive areas of use.
Treppy double folding step
The Treppy is a compact, lightweight aluminium step with a footprint of 350 x 200 mm for safe standing when working at low heights. Thanks to its anodised uprights, it not only stays clean but is also easy to clean, making it the perfect choice for applications in hygienic areas. The sturdy metal articulated joints and integrated folding lock guarantee safe use. Thanks to its compact design, it can also be stowed away to save space.
With the anodised models, KRAUSE offers the right solution for every work situation - whether in the home, in trade or in industry. Anodised ladders impress with their combination of durability, ease of care and professional appearance. They are the ideal choice for users who value quality, durability and sustainability.
