Surface Metal Treatment – Shot Blasting, Sandblasting & Vibratory Finishing

Surface Treatment Machinery and Equipment

We are equipped to perform surface treatment on black steel, stainless steel and non-ferrous metals. Each process is based on carefully selected abrasives and optimal operating parameters, enabling effective cleaning, smoothing and achieving the required surface profile.

Our machinery park includes, among others:

• Shot blasting machines – for intensive removal of rust, paint and contamination

• Vibratory finishing machines – for deburring and achieving uniform roughness

• Polishing equipment – for glossy or matte finishes according to project needs

• Sandblasting stations – for precise cleaning and preparation of surfaces for protective coatings

Surface Treatment –  Shot Blasting, Powder Coating, Galvanizing & Protective Coatings

As part of metal surface treatment, we offer comprehensive preparation of components for further processing and use.
Shot blasting enables the effective removal of impurities, scale and old coatings, while also creating the proper surface profile for painting or galvanization.

Powder coating, hot-dip galvanizing and electro-galvanizing significantly increase corrosion resistance and protect components against environmental factors, while ensuring an aesthetically uniform final appearance.

Powder Coating, Hot-dip Galvanizing & Electro-galvanizing

In cooperation with trusted subcontractors, we provide powder coating, hot-dip galvanizing and electro-galvanizing.

This allows you to complete both surface preparation and final anticorrosive protection in one place — simplifying logistics, shortening the supply chain and improving quality control of finished components.

Final Metal Finishing at Protec

During final finishing, we focus on repeatability and full compliance with technical documentation. Our team selects the abrasive media type, processing time and appropriate technology based on the metal type, geometry and expected visual effect.

Thanks to this approach, we can successfully support both prototype batches and large-scale production orders while maintaining a consistent surface quality at every stage.

Stages of the Metal Surface Treatment Process

At Protec, the surface treatment process includes:

1. Component assessment & technology selection – selection of shot blasting, vibratory finishing or polishing methods and abrasive media

2. Initial preparation – pre-cleaning and removal of loose contaminants

3. Main processing – abrasive blasting, vibratory finishing or polishing according to project assumptions

4. Quality control – verification of roughness, cleanliness, surface appearance and compliance with customer requirements

Benefits of Surface Treatment at Protec

Partnering with Protec in the field of surface treatment offers:

• Tailored processing parameters based on component geometry and use case

• High resistance to external conditions after application of protective coatings

• Repeatability of results in consecutive production batches

• Possibility to combine surface treatment with other services such as Metalworking, CNC Machining or Metal Heat Treatment

Industries Using Metal Surface Treatment

Our services are used by companies from the construction, energy, machinery and automotive sectors. The processed components are delivered to both domestic and international customers, where stable quality parameters and repeatable surface finish are required.

Surface treatment at Protec is suitable for both serial production and complex components requiring precise finishing.
