Galvanising OTR Metal Wheel Rims for Agricultural and Industrial Vehicles
For Agricultural and Industrial Vehicles
Hot-dip galvanising metal wheel rims used in agricultural and industrial vehicles offers numerous specific advantages. This surface treatment protects the rims from corrosion, increases their lifespan, and ensures better resistance to mechanical stresses. By extending the service life of the rims, hot-dip galvanising creates significant value and profit, as less maintenance and replacement are required.
Hot-dip galvanising is an ancient process where steel is dipped in molten zinc at a temperature of approximately 450°C. Through the diffusion of liquid zinc with the surface of the steel object, zinc-iron alloys with various compositions are formed, covered with a strongly adhering layer of pure zinc. The zinc layers are applied in accordance with ISO 1461.
Even when there are small damages in the zinc layer, the zinc protects the steel through its electrochemical potential (cathodic protection). Due to special advantages such as corrosion protection on both the inside and outside of the structure and optimal edge coverage, hot-dip galvanising is a sustainable form of corrosion prevention.
After inspecting the delivered product, it is correctly hung on a traverse using lifting equipment. During a wet chemical pre-treatment, all impurities are removed and the steel surface is activated with a liquid solvent. The actual galvanising then takes place.
During hot-dip galvanising, zinc-iron alloys can form at different rates. The chemical composition of the steel, particularly the silicon and phosphorus content, is crucial. At certain concentrations, these elements accelerate the reaction between iron and zinc, resulting in grey and thick zinc layers. For a perfect optical result, it is advisable to consider this during the planning phase.
High-temperature galvanising is an advanced dipping process where steel structures are treated in a ceramic and inductively heated zinc bath at temperatures ranging from 560 to 630°C. This allows thin zinc layers from 25 µm to more than 100 µm to be applied according to ISO 1461, as desired by the customer. A zinc alloy at high temperature provides the same protective effect as with hot-dip galvanising.
Hot-dip galvanising provides extremely durable corrosion protection. Under normal conditions, items are protected against corrosion for more than 40 years, and even under higher stress (e.g., in industrial areas or coastal regions), the protection period is generally more than 25 years.
The zinc coating provides reliable corrosion protection that is applied industrially and according to fixed conditions in compliance with ISO 1461.
The application of hot-dip galvanising to metal wheel rims used in industry and agriculture significantly increases the lifespan of the rims. The superior surface protection enhances the value and profitability of the rims, as less maintenance and replacement are required. This makes hot-dip galvanising an economical and sustainable choice for companies in these sectors.
