In the field of industrial electrical, metal distribution boxes are often regarded as functional products - users are more concerned about the material, protection level and internal configuration.
However, with the upgrading of urban landscape, the unification of enterprise brand image and the increasing requirements for the integration of outdoor equipment and environment, the surface color of distribution box has changed from a single "industrial ash" to diversified customization.
This paper introduces the process flow, color card selection and attention of metal distribution box customized color.
| Process of operation | Content | Critical control point |
| Surface pretreatment | Oil removal, rust removal, phosphating treatment | Ensure coating adhesion and prevent shedding |
| Primer spraying | Epoxy zinc-rich primer or general anti-rust primer | Thickness ≥30μm, enhance anti-corrosion |
| Spray finish paint | Apply polyurethane or outdoor powder coating according to customer's color card | The color is accurate and the coverage is uniform |
| Curing by baking | Constant temperature oven (180-200℃, 20-30 minutes) | Ensure that the coating is fully cured and the hardness is ≥2H |
| Film thickness detection | Spot check of coating thickness meter | The total film thickness is 60-120μm |
| Color difference detection | Colorimeter compares standard color plates | ΔE≤1.5 (no significant difference visually) |
Tips:The Electrostatic Powder Coating is strongly recommended for outdoor use. The weather resistance of the coating is better than that of liquid spraying, the anti-ultraviolet aging ability is stronger, and the color retention time can reach 5-8 years.
We can provide color matching according to the following standards:
| Color card type | Application scenarios | Remarks |
| RAL 7035 (light grey) | Conventional indoor distribution box | Industrial standard color |
| RAL 7040 (window ash) | Outdoor cabinet, communication box | Dirt resistant, compatible with most environments |
| RAL 9003 (signal white) | Hospital | Visual clarity |
| RAL 1007 (bright yellow) | High voltage warning equipment | High visibility |
| RAL 6005 (moss green) | Parks, green belts | Integration of environment |
| Customize samples | Brand equipment, special projects | Color card number or sample should be provided |
| Customer type | customized color | use |
| A new energy charging pile operator | RAL 3020 (Traffic Red) | Branding Integration, improve site recognition |
| A scenic spot management company | RAL 6005 (moss green) | The distribution box is integrated with the green belt |
| A chemical plant | RAL 1018 (Zinc yellow) | High pressure area warning |
| A communication base station project | RAL 5005 (bright blue) | Cooperate with enterprise VI system |
