Services / Surface Treatment
Surface Treatment
Powder coating, wet painting, anodizing, galvanizing, and electropolishing. We provide the right protective and decorative finish for every metal component, completing your production chain through a single point of contact.
Overview
Protection & Appearance in One Step
Surface treatment is the final critical step that determines how your parts perform in service. MegaMETA coordinates a full range of coating and finishing processes, ensuring every component is delivered with the corrosion protection, wear resistance, or aesthetic finish your application demands.
We match the right treatment to each material and end-use environment, whether it’s a powder-coated steel frame for outdoor equipment, an anodized aluminum enclosure for electronics, or an electropolished stainless steel surface for food-grade hygiene. All treatments are managed through our quality system with full traceability.
Finishing Processes
Five Treatments, Full Coverage
Coating
Powder Coating
Dry powder electrostatically applied and heat-cured into a tough, uniform finish. Excellent corrosion and impact resistance with a wide range of colors, textures, and gloss levels for steel and aluminum parts.
Coating
Wet Painting
Liquid paint application for precise color matching and customization. Supports an extensive range of RAL colors, metallic effects, and multi-layer systems for demanding aesthetic and protective requirements.
Electrochemical
Anodizing
Electrochemical oxidation that creates a controlled oxide layer on aluminum surfaces. Increases hardness, improves corrosion resistance, and allows decorative coloring while maintaining the metallic appearance.
Metallic
Zinc Coating (Galvanizing)
Hot-dip galvanizing or electroplating applies a protective zinc layer for exceptional durability against corrosion and environmental exposure. Ideal for outdoor structural components and heavy-duty equipment.
Electrochemical
Electropolishing
Electrolytic surface smoothing that enhances brightness, cleanability, and corrosion resistance of stainless steel and other alloys. Essential for food-grade, pharmaceutical, and medical device components.
Selection Guide
Matching Treatment to Application
Choosing the right surface treatment depends on the base material, operating environment, and appearance requirements. We help you select the optimal process for each project.
| Treatment | Best For | Key Benefit |
|---|---|---|
| Powder Coating | Steel, aluminum structural parts | Durable color finish, impact resistant |
| Wet Painting | Complex shapes, color-critical parts | Precise RAL matching, special effects |
| Anodizing | Aluminum components | Hard oxide layer, decorative colors |
| Zinc Coating | Outdoor steel structures | Long-term corrosion barrier |
| Electropolishing | Stainless steel, medical/food parts | Smooth, hygienic, corrosion-free surface |

FAQ
Frequently Asked Questions
Powder coating is more durable and impact-resistant, ideal for structural parts. Wet painting offers precise RAL color matching, metallic effects, and multi-layer finishes for parts with demanding aesthetic requirements.
Anodizing is primarily used for aluminum and its alloys. The electrochemical process creates a hard oxide layer that improves corrosion resistance, surface hardness, and allows decorative coloring.
Hot-dip galvanized coatings typically provide 25-50+ years of corrosion protection depending on coating thickness and environmental exposure, making it ideal for outdoor and marine structures.
Electropolishing smooths and brightens stainless steel surfaces, removing micro-roughness and improving cleanability. It is essential for food-grade, pharmaceutical, and medical device components requiring hygienic finishes.
Yes. We accept parts from external sources for surface treatment, provided they meet our preparation requirements. We’ll advise on any pre-treatment needed for optimal coating adhesion.
Yes. We measure dry film thickness (DFT), perform adhesion testing per ISO 2409, and can arrange salt spray testing. Full documentation is included in our quality package.
We offer the full RAL colour range plus custom colours, with options for gloss, satin, matte, and textured finishes. We can match specific colour references on request.
