Industrial surface treatment companies

Industrial surface treatment companies

Find suppliers that protect, clean and improve metal surfaces through anodising, galvanising, zinc plating, electrolytic coatings, industrial painting, electropolishing and other technical finishes.

Find a process suited to the substrate, function and service environment

Aragón Sourcing brings together Aragon-based companies specialising in the preparation, protection and finishing of metal parts, components, profiles, assemblies and structures.

Supplier search can be guided by substrate, dimensions, weight, corrosion resistance, wear, chemical exposure, colour, texture, thickness, standard, batch size, lead time and inspection requirements. Aragón Sourcing acts as a directory and connection point; final process definition and quotation are provided by the selected supplier.

Surface treatments and finishes you can source

Compare suppliers by substrate, geometry, treatment purpose, exposure, appearance, tolerances, standard, volume and line capacity.

Surface preparation and cleaning

Degreasing, pickling, washing, shot blasting, abrasive blasting and pretreatments to remove oxides, oils, scale and contaminants before coating.

Aluminium anodising

Electrochemical treatment to improve corrosion and wear resistance, enhance appearance and provide technical or decorative finishes.

Hot-dip galvanising

Coating iron and steel by immersion in molten zinc, for structures, parts and assemblies exposed to corrosive environments.

Zinc plating and electrolytic coatings

Controlled metallic deposits used to protect parts, modify surface properties and meet functional or aesthetic requirements.

Industrial painting and powder coating

Liquid paint, powder coating and lacquering for protection, colour, texture and finish on metal parts, assemblies and structures.

Electropolishing and passivation

Processes that reduce microroughness and improve cleanability, brightness and corrosion resistance, particularly on stainless-steel components.

Substrate, geometry, performance, finish and inspection

A well-defined enquiry enables the supplier to review compatibility, surface preparation, process, racking, thickness, masking, inspection, packaging, lead time and cost.

What to verify before awarding the work

In addition to price, assess process compatibility, dimensional capacity, preparation, inspection, environmental management and logistical protection of the finish.

Technical compatibility

Experience with the substrate, geometry, previous treatment, part function, service environment and applicable specification.

Dimensions and capacity

Maximum size, weight, tank or furnace length, batch load, automation, throughput and suitability for series or one-off parts.

Surface preparation

Cleaning, pickling, blasting and pretreatment method, contamination control and management of areas that must remain uncoated.

Inspection and testing

Thickness, adhesion, appearance, colour, roughness, corrosion, hardness, cleanliness, traceability, certificates and acceptance criteria.

Environmental and safety management

Management systems, bath and waste treatment, legal compliance, chemical handling and working conditions.

Packaging and logistics

Protection against impact, marks and corrosion, separators, identification, returnable packaging, transport and finish preservation.

Tell us which treatment or finish your part requires

Which surface treatments can I source in Aragon?

The directory includes suppliers for preparation and cleaning, anodising, hot-dip galvanising, zinc plating and electrolytic coatings, industrial painting and powder coating, electropolishing, passivation and other finishes. Exact availability should be checked in each profile.

State the material and alloy, dimensions and weight, initial surface condition, required treatment or target performance, applicable standard, colour or finish, masking areas, critical tolerances, quantity, frequency, packaging and testing or traceability requirements.

Selection depends on the substrate, service environment, corrosion, wear, temperature, chemical exposure, appearance, tolerances and applicable standards. Where no fixed specification exists, request a technical proposal and validate samples.

Yes. Aragon has companies focused on one-off parts or small batches and others operating automatic lines for series production. Confirm dimensions, weight, line capacity, minimum batch, lead time and repeatability with each supplier.
