The leader in corrosion protection, quality assurance and environmental protection
C + P products have been known for their high quality standards for almost 100 years.
Environmental protection is a central aspect of C + P varnishing. We use paint products made in Germany. Our paint suppliers are certified according to EMAS, ISO 9001, ISO 14001, ISO 45001 and IATF standards. We operate sustainably, using only VOC-free paints in efficient systems.
Continuous quality inspections during the varnishing process help us ensure our customers’ color preferences are met. We offer high-quality enamel coatings with durable and eco-friendly dip and powder coating systems for excellent lightfastness. C + P’s coatings correspond to the RAL color register. Continuous system monitoring and color analysis according to the RAL 840-HR color register ensure this quality is maintained consistently.

C + P Cleaner
Ensures optimal surface cleaning of your C + P cabinet.
C + P Cleaner guarantees streak-free cleanliness for automated and manual cleaning applications. Dust, fingerprints and light oil stains disappear effortlessly. Its user-friendly handling makes it “ready to use”. Made in Germany, it stands for reliability and efficiency in every application.
Application: Spray the cleaner on steel surfaces and then wipe with a soft cloth or soft paper towel Go to the safety data sheet
Types and prevention of corrosion on steel materials
Metallic materials are at risk of corrosion if they are not adequately protected. This natural process is due to various chemical and electrochemical reactions with dirt particles, bacteria, substances like water or oxygen or electric current. Each substance causes oxidation of the metal, which leads to the classic corrosion effect.
Corrosion in steel manifests in different ways. According to the DIN standard DIN EN ISO 8044, there are more than 30 types of corrosion. The most common include: uniform corrosion, pitting corrosion, crevice corrosion, cavitation corrosion, galvanic corrosion, stress corrosion.
Steel components are mostly affected by the first type of corrosion. This type is characterized by its uniform distribution on the material surface. It usually occurs due to weather influences and/or moisture, noticeable by a reddish discoloration of the material.
Pitting, cavitation and crevice corrosion are much more dangerous. They attack steel and stainless steel surfaces more aggressively, causing holes and breaking welds. Stress corrosion results from static influences, while galvanic corrosion occurs when two different metallic materials come into contact.
Quality assurance at C + P
Continual tests and test series are required in order to maintain and improve our quality standard. In our own laboratory and the attached testing chamber, for example, we test not only product details, but also the complete product. The latest scientific testing methods are applied in these processes. An important criterion requiring constant monitoring is surface and corrosion protection, particularly for our steel lockers.
The following test methods are used regularly at the C + P testing laboratory:
- Load and bay load of parts and cabinets (up to 4500N)
- Durability tests of drawers and pull-outs with at least 50,000 opening and closing cycles
- Door opening overextension test (up to a 190° opening angle)
- Durability of construction joints
- Continuous stress and lifespan testing
- Surface quality and drying behavior in lockers
- DIN 50021 Salt spray test with subsequent testing according to
- DIN 53167 DIN 50017 Condensation test with subsequent testing according to DIN 53209
- DIN 53151 Cross-cut adhesion test
- DIN 67530 Evaluation of gloss
- DIN 53153 Buchholz indentation resistance test
- DIN 5033 Colorimetry
Maintenance, repair and replacement for steel corrosion protection
At C + P Möbelsysteme, we place great importance on product quality, paying special attention to corrosion and corrosion protection. When you choose one of our lockers, cabinets, or other trend products, you can rest assured that they not only have GS Certification but that they have also been pre-treated with corrosion protection for steel.
Depending on the intended use, we distinguish between different corrosion classes:Class I (for dry zones) • Class II (for humid zones) • Class III (for wet zones) • Class IV (for extreme zones)
For our lockers in classes I and II, we offer a five-year corrosion protection warranty, for class III models, the warranty is ten years and for class IV lockers, it’s an impressive 15 years.
Smaller rusty spots that threaten to disrupt the original color concept can be removed with vinegar essence. Completely rusted and thus irreparable parts should be replaced not only for aesthetic reasons but also for safety.
Frequently asked questions about corrosion and corrosion protection
Rust occurs when metals come into contact with dirt, moisture, electricity, oxygen or hydrogen. The natural process can be prevented with comprehensive steel corrosion protection, such as through alloys, zinc-plating or suitable rust-proof coatings.
To ensure effective corrosion protection, it is important to know in advance how different metallic materials react. Aluminum parts are best treated with specially designed coatings that ensure surface sealing. For corrosion-resistant stainless steel, active protection in the form of a highly rust-resistant chrome-nickel steel alloy is recommended.
The steel cabinets and lockers in your company should undergo regular visual inspections to detect and eliminate any early signs of steel corrosion.
Corrosion and corrosion protection deserve special attention
Even the highest quality raw steel cannot withstand the natural process of corrosion. It is crucial to protect it from rust in advance. With steel cabinets and lockers from C + P Möbelsysteme, you can rely on long-lasting corrosion protection, a result of decades of perfected expertise.
