About CHIER: Door Handle and Window Handle Manufacturer

CHIER supports window and door manufacturers, hardware brands, importers and distributors with window handles, door handles and related hardware. From requirements review and sampling to production, inspection and packing, our role is to help buyers build repeatable supply programs—not simply purchase isolated components.

A Foshan Door and Window Hardware Manufacturer Built Around Buyer Requirements

Based in Foshan, Guangdong, CHIER works on door and window hardware programs where fit, finish, operation and repeat-order consistency all matter. We begin with the application: the profile, opening type, mounting interface, lock or gearbox connection, target finish, quantity and destination market.

Compatibility Comes First

We review drawings, profile sections, physical samples and critical mounting dimensions before recommending a product or defining a development path.

Decisions Stay Traceable

Approved drawings, samples, finishes, packaging requirements and revisions can be recorded against the project to support future orders.

Production Follows the Agreed Standard

Manufacturing, inspection and pack-out requirements are aligned with the approved product and the confirmed order scope.

What We Stand For

Our purpose is straightforward: make door and window hardware easier for professional buyers to specify, validate and reorder.
Application-led product selection
Clear technical and commercial communication
Buyer approval before mass production
Consistent execution across repeat orders

From Individual Components to Complete Hardware Support

CHIER is based in Nanhai District, Foshan, China. Our product work centers on window handles, door handles, locks, hinges, latches and related hardware for professional door and window applications.

As buyer requirements became more detailed, our role expanded beyond supplying standard components. Today, CHIER supports existing-product selection, build-to-drawing, build-to-sample and co-development programs according to the requirements confirmed for each project.

The principle remains the same: a handle, lock or hinge is only successful when it fits the system, operates as expected and can be reproduced consistently for future orders.

Face to Face With Door and Window Hardware Buyers

Trade exhibitions give our team an opportunity to discuss real applications directly with manufacturers, importers, distributors and project buyers. Buyers can compare samples, review handle operation, discuss profile compatibility, evaluate finishes and clarify packaging or documentation requirements before moving forward.

Compatibility review may include the profile section, mounting centers, base dimensions, door or window thickness, spindle or fork length, handing, rotation and the lock or gearbox interface. Final compatibility should be confirmed against an approved drawing or sample.

Sampling and buyer approval can be included before mass production. The relevant dimensions, appearance, operation, finish and packaging acceptance points should be agreed during the sample stage.

Logo application, barcode labels, carton marks, instruction sheets, inner packaging and mixed-SKU requirements can be reviewed according to the project. The exact options should be confirmed before quotation and sample approval.

Document availability varies by product and project. Ask for a model-specific list, which may include drawings, inspection records, packaging specifications, material or finish information and applicable test reports.
