At Shenzhen Urain Metal Products Co., Ltd., we continuously optimize our manufacturing processes to deliver high-quality sheet metal parts that meet international standards for appearance, durability, and performance. Recently, we have upgraded our surface treatment production line with more precise, efficient, and eco-friendly technologies, providing better solutions for global customers in machinery, electronics, new energy, and outdoor equipment industries.
Professional Surface Treatment Processes We Provide
Our comprehensive surface finishing capabilities cover almost all common requirements for sheet metal fabrication:
- Powder Coating: Ensures strong adhesion, uniform color, and excellent corrosion resistance. Ideal for outdoor cabinets, electrical enclosures, and structural parts.
- Spray Painting: Supports custom colors and textures for high-end appearance and brand consistency.
- Brushing & Polishing: Creates a smooth, clean metallic finish widely used in electronic enclosures, medical devices, and decorative parts.
- Sandblasting: Improges surface roughness for enhanced coating adhesion and removes burrs, oxide layers, and stains.
- Passivation: Especially for stainless steel parts, improves rust resistance and extends service life.
- Anodizing: For aluminum sheet metal parts, enhances hardness, wear resistance, and corrosion resistance.
Why Our Surface Treatment Stands Out
-
Strict Quality ControlWe conduct standardized tests including adhesion test, salt spray test, and color difference test to ensure every finished part meets customer specifications.
-
Eco-Friendly & ComplianceOur processes comply with RoHS, REACH, and other international environmental standards, supporting safe exports to Europe, North America, and other regions.
-
High Efficiency & Stable Lead TimeWith fully automated production lines, we significantly reduce manual errors and ensure fast, stable delivery even for mass orders.
Customer Case
Recently, we completed a large order of outdoor electrical enclosures for a European client. By combining sandblasting + powder coating, the products achieved excellent weather resistance and passed over 500 hours of salt spray testing. The client praised our stable surface quality and on-time delivery performance.
Conclusion
Surface treatment is a critical step that directly determines the appearance, durability, and value of sheet metal products. With our upgraded capabilities, Shenzhen Urain Metal Products Co., Ltd. is ready to support global customers with reliable, customizable, and cost-effective sheet metal fabrication and surface finishing solutions.
