Our Position in Hinged Door Hardware
WANO is a Hinged Door Hardware manufacturer and supplier with R&D and production facilities in Ningbo, China. Established in 2003, we design and manufacture door handles, hinges and lock bodies for hinged door systems used in residential villas, commercial buildings, hotels, apartments and public facilities.
We supply fabricators, system window brands, architectural hardware dealers and project clients with complete hardware sets rather than isolated components. Each set is engineered as a system: hinge load rating is matched to the door leaf weight, lock body specification matches the required security level, and handle design supports the interior finish. Our 38,000 m² manufacturing base, 500 employees and 100-person R&D center support both volume distribution programs and project-specific OEM/ODM development.
What We Supply in This Category
The Hinged Door Hardware range covers the three components that define door operation, security and appearance. We also coordinate matching accessories such as door stops, strike plates and cylinder options as part of a complete package.
| Product | Core Function | Typical Application |
|---|---|---|
| Door Handle | Operating lever for latch retraction and locking action; available in multiple profiles, grip shapes and finishes. | Residential and commercial hinged doors where ergonomics and interior style matter. |
| Door Hinge | Supports the door leaf and guides smooth opening and closing; butt and pivot hinge types for varied load requirements. | Single- and double-action doors, including heavy sashes and high-traffic entries. |
| Door Lock Body | Engages locking points and coordinates handle operation; multiple backset and latch configurations. | Entrance doors, room doors and public building assemblies with defined security requirements. |
Application Fit Across Building Types
We position the range by building scenario rather than by component alone, because cycle frequency, security exposure and finish expectations differ significantly between project types.
- Residential villas: design-conscious handle profiles, quiet hinge action and corrosion-resistant finishes for coastal environments.
- Commercial buildings: higher cycle endurance, consistent locking geometry and tamper-resistant fixing.
- Hotels & apartments: durability under repeated guest use, simplified maintenance and optional brand marking on handles and packaging.
- Public buildings: robust lock bodies, multi-point configurations and documented test evidence for acceptance.
Materials, Finish and Critical Specifications
Hinged door hardware carries repeated mechanical load and must maintain appearance over years of service. We select aluminum alloy, stainless steel and zinc alloy for hinge bodies, lock cases and handle bases according to the required strength, weight and environmental exposure.
- Hinge geometry and load rating are matched to door leaf weight, width and opening frequency.
- Lock bodies are configured by backset, latch projection, locking point count and cylinder type.
- Surface treatment options include powder coating, electrophoretic coating and anodizing, with custom textures and colors developed to match interior design languages.
- Salt spray resistance testing verifies corrosion performance for coastal and high-humidity installations.
- Handle operating force is validated through torque testing to ensure ergonomic compliance.
Configuration and Project Customization
Our hinged door hardware is not limited to standard catalog items. We configure opening angle, load capacity, adjustment range, locking layout and appearance for the specific door system and project requirement.
- Opening configurations from 90° to 180° for single- and double-action doors.
- Hinge load ratings and 3D adjustment ranges tailored to heavy sashes and narrow-profile systems.
- Multi-point locking layouts for wider and taller door leaves.
- Handle profiles, curvature and grip thickness customized — square or rounded — for minimalist, modern luxury or vintage interiors.
- Brand marking through laser engraving, screen printing or die-cast integrated molding.
- Packaging customization with unit boxes, outer cartons, product certificates and packing lists printed under your brand identity.
We handle the full customization path in-house: requirement consultation, drawing and sample confirmation, technical assessment, sample development and testing, pricing, mass production, inspection, then packaging and delivery.
Quality Assurance and Testing
Quality control starts with incoming material inspection and continues through first-article inspection, in-process monitoring and final pre-shipment verification. Our 15 specialized laboratories support this full-process chain.
- Torque testing to verify handle operating force meets ergonomic and industry requirements.
- Load and tensile testing to confirm the ultimate load-bearing capacity of hinges and locking points.
- Opening and closing cycle testing to simulate tens of thousands of operations and verify durability.
- Salt spray resistance testing to validate surface treatment stability in corrosive environments.
Information We Use to Configure Your Solution
To prepare a precise proposal and quotation, we work from the following project inputs. The more complete the data, the shorter the sample and approval cycle.
- Door leaf dimensions, weight, thickness and opening direction.
- Frame material, profile system and hinge preparation details.
- Required security level, locking point count and cylinder specification.
- Expected usage frequency and environmental conditions, including coastal or high-humidity exposure.
- Finish color, texture, handle profile and brand marking requirements.
- Target order volume, packaging format and delivery schedule.
Frequently Asked Questions
Can we order door handles, hinges and lock bodies as a matched set?
Yes. We supply the three components as a coordinated package, with hinge load rating, lock body geometry and handle style matched to the same door specification and finish requirement.
Do you support custom surface finishes?
We offer powder coating, electrophoretic coating and anodizing, and we can develop custom textures and colors for handles and hinges. Salt spray testing is used to verify the finish for coastal and high-humidity installations.
What project information do you need for a quotation?
Door leaf size and weight, frame material, opening direction, security level, finish and branding preference, order volume and packaging format. With these inputs we prepare a technical assessment, samples and pricing.
How is durability verified for high-traffic doors?
We simulate tens of thousands of opening and closing cycles and perform load and tensile testing on hinges and locking points to confirm that the hardware maintains smooth operation and structural integrity.
Can you produce private-label packaging?
Yes. We print individual unit boxes and outer cartons with your logo, brand name and product model details, and we can provide neutral or brand-exclusive packaging with fully rebranded certificates and packing lists.
