Products & Materials
Useful starting points for selecting conductive materials and product categories.
Which products does Dongyao supply?
We supply copper busbars, copper plates, copper rods, neutral bars, aluminum busbars, and drawing-based custom aluminum parts for electrical and industrial projects.
How do I choose between copper and aluminum busbars?
The selection normally depends on conductivity, weight, installation space, operating conditions, and the overall project budget. Send the application details and dimensions so the material discussion can be more specific.
Can you help with product selection before I place an order?
Yes. Share the intended application, material preference, dimensions, drawing if available, and quantity. We can review the requirement before preparing a quotation.
Custom Processing
Questions about drawings, machining details, finishes, and sample review.
Do you support custom busbars and aluminum parts?
Yes. We can discuss drawing-based hole positions, bends, special shapes, dimensions, surface finish, insulation requirements, and packing details for custom conductive parts.
What information should I send for a custom requirement?
Please include a drawing or sketch, material or grade preference, dimensions, tolerances, holes or bends, surface treatment, quantity, packing needs, and the final application when possible.
Can a sample be reviewed before batch production?
Sample requirements can be reviewed during the technical discussion. The appropriate process depends on the product complexity, material, quantity, and confirmation points in the drawing.
Quotation & Orders
Clear inputs help us prepare a practical quotation and supply plan.
What do you need to prepare a quotation?
Please send the product name, drawing or dimensions, material, surface requirement, quantity, packing requirement, destination, and any target delivery date. We will use these details to review the request.
Can you support repeat or project-based purchasing?
Yes. For repeat supply, it is helpful to confirm the final specification, product code, packing, batch quantity, and delivery arrangement so the requirement stays consistent across orders.
How is the final specification confirmed?
Before production or supply is arranged, the key details are reviewed with you, including dimensions, material, processing points, surface finish, quantity, packing, and delivery destination.
Delivery & Support
Answers for packing, shipping preparation, and ongoing technical communication.
Can you arrange export packing and shipping support?
We can discuss export packing and delivery requirements as part of the order review. Please provide the destination, transport preference, packing expectations, and any project-specific handling needs.
How can I check the progress of an order?
Contact our team with the product and order reference. We will coordinate the relevant production, packing, and delivery information for your update.
I still have a technical question. Who should I contact?
Send your requirement through the contact page with the product name, drawings, photographs, dimensions, and application details. This gives our team the context needed for a useful reply.
