Customization Costs: Design + Materials + Processing
The cost structure for custom power distribution cabinets includes: design fees (drawings and plans), material costs (sheet metal and components), processing fees (assembly and workmanship), and accessory costs. The total price is typically 10% to 40% higher than that of a standard cabinet. Industry experts note that the cost depends on the level of customization: minor customization (such as dimensional adjustments) incurs a small markup, whereas deep customization (non-standard designs) involves cumulative design and processing fees;
therefore, it is important to clarify the cost structure when obtaining a quote.
Cost Reference (Based on Industry Pricing Practices)
- Standard power distribution cabinets (e.g., GGD series): 10,000–50,000 RMB per unit;
custom versions incur a markup; - Minor customization (adjustments to dimensions, color, or labeling): 10%–20% markup;
- Deep customization (non-standard designs, special components): 20%–40% markup, including design fees;
- Design fees: Often charged for deep customization (ranging from hundreds to thousands of RMB per design); may be waived for bulk orders;
- Component upgrades (imported brands/smart configurations): Charged separately based on the price difference of the components.
Four Components of the Cost
First is the design fee. Non-standard designs require blueprints and a Bill of Materials (BOM);
design fees are listed separately (though costs may be amortized or waived for bulk orders).
Second is material cost.
Sheet metal (steel plate specifications and thickness) and components (brand and grade) constitute the bulk of the cost, accounting for 60%–70%.
Third is processing cost.
This covers CNC sheet metal fabrication, welding, coating/painting, and assembly.
Fourth is accessory cost.
This includes expenses for busbars, connectors, mounting brackets, and other accessories.
Key Points for Cost Control
First, simplify the design.
Make minor adjustments to standard models rather than opting for extensive customization.
Second, tier the components.
Prioritize brand-name components for core functions while selecting cost-effective options for non-core parts.
Third, leverage batch production to spread costs.
Amortize design fees across multiple units to lower the per-unit price.
Fourth, ensure cost transparency.
Itemize quotes to clearly separate design, material, and processing fees for individual verification.
Pitfalls to Avoid
First, beware of “hidden design fees.”
Design costs may be quietly rolled into the unit price; clarify the cost structure.
Second, watch out for “component upgrade surcharges.”
Price hikes due to component upgrades after design confirmation can occur;
lock in the bill of materials early.
Third, avoid “omitted accessory costs.”
Ensure accessory fees are accounted for and included in the total price calculation.
Trends and Reminders
Custom power distribution cabinet costs are trending toward “modular cost reduction”: modular design lowers customization costs, while digital quoting ensures cost transparency.
For purchasers, the recommended strategy is to “simplify designs, itemize costs, and leverage batch production.”
Customization costs reflect the design structure—transparency in costs ensures budget accuracy.
