Zinc phosphating
10 years of reliability and highest protection
Sheet steel, zinc-plated, zinc-phosphated and powder-coated.
The high standards of the automotive industry are now realised for cost-efficient solutions. The result: A considerable increase in corrosion protection. According to purpose and application conditions it is even possible to partly substitute aluminium. Zinc phosphating is based on hot-dip galvanised sheet steel, Z 275.
With this combination of material selection a maximum cathodic edge protection is achieved. The protection effect of galvanising is considerably increased by zinc phosphating. The subsequent high-quality powder coating offers additional protection and makes individual colours possible. Optimum rust protection at moderate costs - tests in neutral laboratories underline this new Rittal quality:
Aluminium coating
Galvanic coating with aluminium or AIMg alloys offers completely new prospects.
Special benefits: ingenious corrosion protection and biocompatibility. This surface is used for fitting parts, for example.
Extreme protection for outdoor enclosures: The best will be standard, the impossible will be possible
Our customers assume that our outdoor enclosures resist against expected stresses without 'ifs and buts'. From the basic requirements (humidity, temperature variations, solar radiation) up to extreme ambient stresses (seawater resistance, earthquake protection, vandalism protection) Rittal offers a suitable solution. New in our extreme protection range: zinc-plated sheet steel with zinc phosphating - the surface finish in the automotive industry.
Sheet steel, aluminium-zinc coated, iron-phosphated and powder-coated.
The outstanding standard corrosion protection for all indoor and many outdoor requirements. Surface coating layers: Sheet steel, aluminium-zinc coating, iron-phosphating, powder coating.
Aluminium
Aluminium AIMg3 - the material for all outdoor requirements.
With outstanding features, e.g. light weight and high static load capacity.
Stainless steel
Stainless steel 1.4301 (AISI 304) or stainless steel 1.4571 (AISI 316 Ti) - the material for maximum demands of corrosion, hygiene and for robust mechanical protection.
Corrosion protection push for outdoor enclosures
To improve sophisticated products - this claim is a constant challenge for the Rittal product development. How it is possible to connect a basic increase in quality with a maximum level of efficiency shows the new procedure of zinc phosphating for outdoor applications that equips Rittal enclosures with state-of-the-art corrosion protection.
Outdoor enclosures are partly exposed to extreme conditions from heat and cold up to high humidity. A special demand on corrosion resistance because it is the prerequisite for constant safety and function of sensitive electronic components.
Standards as applied in the automotive industry
Through the process of zinc phosphating the high standards of the automotive industry are now achieved for the corrosion protection of outdoor enclosures.
Here, Rittal sets new standards with regard to safety, durability and efficiency.
In order to improve the quality of the previous procedure - aluminium-zinc coating of sheet steel - new paths have been made with regard to pre-treatment.
The considerable increase in corrosion protection is based on a material change to hot-dip galvanised sheet steel in combination with the new zinc phosphating pre-treatment.
Optimum edge protection
By this means an optimum protection for "sensitive" edges that result from cutting or punching is achieved in addition to the perfect rust protection of surfaces.
The protective effect of galvanising is considerably increased by zinc phosphating.
The subsequent high-quality powder-coating offers additional protection and makes individual colours possible.
10 years of reliability at an excellent price/performance ratio
The result: With the new corrosion protection method for outdoor enclosures Rittal realised the high standards from the automotive industry for its partners as a cost-efficient option in addition to the use of aluminium and steel.
Depending on purpose and conditions of use aluminium can partly be replaced.
This new Rittal quality is underlined by tests in neutral laboratories.
