Surface Treatment (or Surface Finishing) is a process designed to modify a material’s surface, enhancing its durability, aesthetics, and functionality. Commonly applied to metals, plastics, and glass, it creates protective coatings or decorative layers. This technique is essential for maximizing corrosion resistance, wear resistance, and the overall visual appeal of components.
What is Surface Treatment?

Surface Treatment Types - Process Overview
At Sureton, we provide high-quality surface finishing services that boost durability, superior corrosion protection, and visual appeal. Our eco-conscious surface treatments comply with rigorous environmental regulations, supporting your goals for green manufacturing and sustainable product development.
Custom Painting
We apply advanced, eco-friendly paints to create precise, customizable color finishes. Our spray painting service ensures a smooth, high-quality decorative appearance for a wide range of surfaces.
Industrial Powder Coating
Designed for metal surfaces, this technique provides a robust shield against rust and scratches. Offering superior corrosion resistance, it ensures outdoor durability for heavy-duty industrial equipment.
UV Surface Treatment
Using instant UV curing technology, this method boosts surface hardness and chemical resistance. UV coating is the optimal choice for protecting precision components with a long-lasting, premium finish.
