Door Hardware includes every mechanical component used to hang, open, close, secure, protect, seal, identify, or control a door. The main types of door hardware are handles, locks, cylinders, latches, hinges, door stoppers, bolts, guards, viewers, drop seals, closers, and mounting accessories.
Selecting architectural door hardware requires more than matching finishes. Door material, thickness, weight, traffic level, fire or emergency function, exposure, accessibility, security, and local building requirements all influence the correct specification.
Handles allow users to operate or move the door. Common formats include:
Lever handles
Pull handles
Knob handles
Recessed pulls
Back-to-back glass door handles
Tubular and solid stainless steel handles
Handles combined with locks or indicators
Lever handles operate a latch through a spindle and are widely used on bedrooms, offices, hotel rooms, washrooms, and interior doors. Pull handles do not normally retract a latch by themselves; they are frequently installed on entrance, glass, sliding, and commercial doors.
Our stainless steel door handle range includes tubular, hollow special-shape, solid, lever, and pull-handle configurations for residential and project applications.
A door lock controls authorized access. Depending on the application, a lock set may contain a mortise body, latch bolt, deadbolt, cylinder, spindle, handles, escutcheons, thumb turn, and strike plate.
Common lock applications include:
Entrance doors requiring key control
Hotel doors using electronic credentials
Offices requiring controlled access
Bedrooms requiring privacy
Washrooms using thumb turns and indicators
Storerooms requiring restricted access
Security depends on the complete door assembly. A strong lock cannot compensate for a weak frame, poorly fitted strike, unsuitable cylinder, or loose hinges.
A latch holds a closed door without necessarily providing key-operated security. Lever handles commonly retract the latch through a square spindle.
Passage latches suit rooms that do not require locking. Privacy latches may work with a turn or indicator, while roller latches are used where the door should remain closed without conventional lever operation.
Hinges support the door and establish its pivot point. Butt hinges are common on timber and metal doors, while concealed hinges provide a less visible architectural finish. Bearing hinges can be selected for doors subject to frequent movement or greater loads.
The correct stainless steel door hinge depends on door weight, dimensions, material, usage frequency, frame construction, and environmental exposure.
A door stopper limits travel and helps prevent the handle or door leaf from striking a wall. Floor-mounted, wall-mounted, magnetic, and rubber-cushioned designs serve different layouts.
Door guards, chains, bolts, and viewers add controlled opening or secondary protection. These components should be positioned where users can operate them safely and where the door construction provides adequate fixing strength.
A drop seal is installed at the bottom of a door. When activated, it lowers a sealing element toward the floor and retracts when the door opens.
Depending on the complete tested assembly, sealing hardware may help reduce light, drafts, dust, smoke movement, or sound transmission. Performance claims should be supported by the applicable test method rather than assumed from appearance.
Public-space hardware includes toilet-partition fittings, Handrails, Balustrade components, door signs, and high-traffic access hardware. Bathroom hardware can include glass hinges, clamps, sliding-door components, seals, and stainless steel handles.
Wet or chemically cleaned environments require careful material and finish selection. SS316 may be more appropriate than SS304 where chloride exposure is significant, but the entire product construction must be verified.
Our factory has produced door and architectural hardware since 1993. Our capabilities include CNC turning, spark erosion, digital-controlled milling, hydraulic pipe bending, cold and hot forming, and high-frequency welding.
As a door hardware OEM/ODM manufacturer, we can manufacture from drawings or project specifications for door factories, hotels, public buildings, shopping centers, property developments, and distributors. Customization can cover material grade, tube or solid construction, dimensions, spindle and lock compatibility, mounting method, finish, logo, packaging, and accessory combinations.
Handles, latches, locks, cylinders, hinges, stops, and seals must work together with the door and frame. A coordinated schedule reduces incompatible parts, installation delays, and inconsistent finishes.
Provide door type, thickness, handing, weight, usage, environment, lock function, and required finish when requesting a project quotation.
