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.
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.

The Team Behind Each Hardware Program
A successful hardware program requires clear responsibility from inquiry through repeat orders. CHIER coordinates the technical, manufacturing, quality and packaging decisions that require buyer confirmation.
Sales & Requirements Coordination
Collecting application details, drawings, samples, quantity, finish, packaging and delivery requirements.
Product & Application Review
Reviewing the opening type, profile, mounting dimensions, spindle or fork, handing and lock or gearbox interface.
Engineering & Sample Development
Coordinating feasibility review, drawings, tooling where required, sample development and buyer approval.
Production Planning
Aligning the approved model, order revision, process requirements, quantity and production schedule.
Quality & Inspection
Defining applicable incoming, in-process and final inspection requirements for the product and order.
Packing & Export Coordination
Confirming labeling, carton marks, barcode requirements, inner packaging, palletization and shipment details.
Built for Professional Procurement
Our customers need information that can be shared across purchasing, engineering, quality and logistics teams. We therefore structure each project around the details required to quote, approve, produce and reorder with fewer assumptions.
Who CHIER Works With

Hardware Brands & Private Labels
Need product differentiation, finish consistency, logo and packaging options, and clear control of approved product versions.
Importers & Distributors
Need a practical SKU range, quantity-based quotations, labeling support, packing consistency and clear references for repeat orders.
