Metal parts used in industry are frequently exposed to moisture, temperature variations and environments that can accelerate corrosion. Even if they are well designed and machined, without proper surface treatment rust, degradation and performance problems can quickly occur. Galvanizing applies a protective layer, usually zinc-based, that protects the base metal and extends its life.

For manufacturers and equipment users in the area, Brasov electroplating services coordinated through HAWEMA offer an effective solution for protecting parts and reducing maintenance costs.

Galvanizing is a process by which a layer of zinc or other protective metals is deposited on the surface of a metal part, usually by galvanic processes or by hot dipping, depending on the technology and application. The main purpose is:

• anti-corrosion protection of the base metal;
• increasing resistance to environmental factors;
• obtaining a more stable surface over time;
• preparation for use in outdoor conditions or wet environments.

The deposited layer acts as both a physical barrier and cathodic protection: even if the surface scratches locally, the zinc continues to protect the underlying steel.

Galvanizing treatments can be applied to a wide variety of components used in industry:

• fasteners (screws, nuts, washers);
• brackets, supports and fasteners;
• light structures and metal frames;
• components for automation and equipment;
• parts used outdoors or in areas with high humidity.

Depending on the geometry and the destination, the working method is chosen: coating in a drum for small parts, coating on frames for larger parts, or other variants adapted to the application.

Through the correct use of brasov galvanizing treatments, direct benefits are obtained:

• Improved corrosion resistance – parts rust much harder;
• Extended lifespan – metal structures and components remain functional for longer;
• Easier maintenance – there are fewer cases of replacement due to rust;
• Uniform technical appearance – the galvanized surface looks clean and professional;
• Good cost/benefit ratio – relatively small investment, significant long-term effect.

For equipment that works in outdoor environments or in non-air conditioned halls, galvanizing can make the difference between a part that lasts a few years and one that runs smoothly for much longer.

HAWEMA integrates surface treatments into the complete solution offered to customers. In projects that include galvanizing, we deal with:

• mechanical machining of the parts to the dimensions required in the drawing;
• surface preparation (deburring, cleaning, where appropriate);
• defining, together with the customer, the requirements related to the type of layer and thickness;
• collaboration with partners specialized in galvanic coatings;
• checking parts after treatment, dimensionally and visually.

The advantage for the customer is that it has a single point of contact for the entire flow – from the semi-finished product, to the machined part and protected by galvanization.

For good results, the treatment is planned from the design and technology phase:

• the right materials are chosen for the part and for the galvanizing process;
• possible changes in dimensions caused by the deposited layer are taken into account;
• determine the areas that must be covered and any surfaces that remain free;
• the order of operations is decided: processing, coating, possible subsequent assembly.

In the case of parts that are also to be assembled, it is important that the type of adjustment and the tolerances are thought out so that the zinc layer does not cause assembly difficulties.

After the treatment is carried out, the parts are checked to confirm that they meet the requirements:

• visual inspection – the uniformity of the layer, the absence of obvious defects;
• dimensional check – where adjustments are important;
• specific testing, on request, for projects with high requirements regarding anti-corrosion protection;
• documentation of results for traceability, especially in the case of recurring series.

This step ensures that the galvanizing process correctly complements the mechanical machining, without compromising the assembly or operation of the assemblies.

Companies from Brasov and its surroundings benefit from several advantages when working with Hawema:

• shorter shipping times for parts;
• quick reaction to project or volume changes;
• direct communication with the technical team;
• the possibility to develop standardized solutions for repeated series.

By integrating Brasov galvanizing services into the processing flow offered by HAWEMA, customers reduce the number of steps they have to manage internally and have better control over delivery times.

If your metal parts and structures work in environments where corrosion is a problem, it's worth considering a galvanizing treatment integrated into your production flow. By collaborating with HAWEMA, galvanizing services Brasov can be combined with mechanical machining, assembly and other surface treatments, so that you receive ready-to-use components, protected and compliant with technical documentation.
