Requirement Review
Share your drawings, samples, target dimensions or reference products. We review the application, structure and key requirements to define the project direction.

Jiulixing supports project buyers, distributors and private-label customers with flexible handle customization covering dimensions, structure, finishes, mounting details and packaging. Our team helps turn clear product requirements into practical, production-ready solutions.
A structured process keeps custom projects easier to manage. We move through requirement review, technical development, sample confirmation and production in four clear stages.

Share your drawings, samples, target dimensions or reference products. We review the application, structure and key requirements to define the project direction.

Dimensions, materials, mounting details, finishes and related requirements are organized into a clear production specification for confirmation.

A sample can be prepared when required to verify appearance, dimensions and key product details before the final specification is approved.

Once the product is confirmed, production is scheduled according to the approved specifications, order quantity and delivery requirements.
Configure key product details around your design, installation and market requirements. Jiulixing supports flexible customization for both project-based orders and private-label product programs.
Overall length, center-to-center distance, tube diameter, projection and handle structure can be adjusted around different door systems and design requirements.

Material specifications can be selected according to product application, durability expectations and target market requirements.

Surface treatment can be coordinated around different architectural styles, bathroom collections and product positioning.

Mounting structures and related components can be adjusted around different door materials, thicknesses and installation conditions.

Private-label details can be coordinated for distributors and product brands that need their own market-ready presentation.


For custom handle projects, sample development gives both sides a chance to verify the product before moving into mass production. Key details such as dimensions, structure, finish and installation fit can be reviewed against the approved specification.
When required, samples can also be checked for assembly condition, mounting compatibility and overall appearance. Any necessary adjustments are confirmed at this stage, helping reduce uncertainty and keep the final production run aligned with expectations.
