Power Distribution Box

Cangzhou Mengqi Hardware Products Co., Ltd. is one of the leading manufacturers and suppliers of power distribution box in China. Please feel free to buy cheap power distribution box made in China here from our factory. All customized products are with high quality and low price.

Optotron specializes in the R&D, manufacturing and customized service of power distribution boxes, serving as an experienced Chinese enclosure manufacturer. We possess mature metal stamping technology with years of industry experience. We supply highly adaptable, robust and stable structural housings for distribution box factories and electrical system integrators. Our product range covers civil, commercial, industrial and special-environment power distribution projects, supporting clients to achieve fast assembly and on-time product delivery.

Precision stamping serves as our core manufacturing process, combined with bending, welding and surface finishing to guarantee consistent quality. Multiple metal material selections are available to match diverse working scenarios

Cold Rolled Steel Sheet Cost competitive raw material, widely adopted for residential buildings and ordinary office buildings. After stamping, it forms standard distribution box housings. Optional post-processes including powder coating and baking finish can further enhance anti-corrosion performance;

Stainless Steel Excellent rust and corrosion resistance, suitable for harsh conditions with high humidity, heavy dust and salt spray. Ideal for outdoor distribution boxes, chemical plant enclosures and offshore platform power housings;

Aluminum Alloy Lightweight, high mechanical strength and outstanding thermal conductivity with moderate corrosion resistance. Perfect for precision instrument distribution boxes, intelligent power enclosures and rail transit supporting distribution equipment

Our distribution boxes are processed on precision CNC stamping equipment. Dimensional tolerance can be controlled within 0.05mm. All cutouts, slots and bending profiles are precisely formed to minimize assembly errors in subsequent procedures. The one-piece forming structure delivers superior strength and impact resistance compared with traditional welded casings. Three mainstream surface treatment options are available： powder coating, galvanization and anodizing

Powder coating features strong coating adhesion and supports custom color matching

Galvanization greatly upgrades anti-corrosion performance

Anodizing is dedicated to aluminum alloy shells, improving surface hardness and visual appearance

We provide graded protection solutions based on different environmental demands：

Dry indoor residential and office power rooms： IP30 basic protection is sufficient

Corridor distribution boxes, underground parking garages and ordinary factory workshops (semi-outdoor or humid indoor)： IP54 for dust and splash water resistance

Fully exposed outdoor equipment including street light control boxes, charging pile housings and municipal monitoring distribution boxes： IP65 high-grade dustproof and waterproof protection required

Our Factory Service Strength

Support drawing-based customization: Adjust outer dimensions, internal rail layout, cable hole positions and cover structure

Small trial orders are accepted for new product verification; automated production lines guarantee stable lead time for bulk orders

Export-oriented packaging solutions to avoid collision damage during long sea transportation

We can provide dimensional inspection reports and technical data sheets to facilitate customs clearance and project acceptance

Confirm the installation environment and target IP protection grade before ordering. If equipment will be deployed outdoors or coastal regions, prioritize stainless steel or upgraded surface anti-corrosion treatment. Clarify internal component layout so we can reserve proper mounting space for DIN rails and terminals;

Our factory manufactures a full lineup of metal electrical enclosures: power distribution boxes, junction boxes, CCTV power housings, LED driver enclosures and meter boxes.
