The main types of door hardware can be grouped by function: movement hardware, operating hardware, latching and locking hardware, door-control hardware, protective hardware and identification accessories. Each category solves a different problem. Planning a bulk supply of complete door hardware sets requires these parts to be matched by door rather than ordered as unrelated pieces.
Movement hardware connects the door to its frame or guides it along a track.
For a conventional swing door, this usually means hinges. Common forms include:
butt hinges;
ball-bearing hinges;
concealed hinges;
pivot hinges;
continuous hinges;
specialist heavy-door hinges.
Ball-bearing hinges reduce friction around the hinge knuckles and are frequently considered for doors that open often. Concealed hinges are selected when the project needs a cleaner appearance and post-installation adjustment.
Our four-ball-bearing hinge is available in SUS201 or SUS304 with several PVD and stainless-steel finishes.
Operating hardware gives the user a place to grip, push, pull or rotate.
A lever operates a latch through a spindle. It is widely used on passage, bathroom, office and entrance doors.
A knob normally turns to retract the latch. Its compact form suits traditional and residential interiors, although its grip requirements differ from those of a lever.
A pull handle does not necessarily operate a latch. It is used to pull open doors equipped with roller catches, closers, separate locks or other control systems.
Our D-shaped pull handle is offered in multiple sizes and is intended for door materials including wood, aluminum, metal and glass, subject to the correct fixing arrangement.
A latch holds the door closed but does not always provide security. A lock adds a controlled method of preventing entry.
This category can include:
tubular latches;
mortise locks;
deadbolts;
cylinders;
privacy bolts;
bathroom turns;
strike plates;
electronic access-control components.
The correct function depends on the room. A passage door, bathroom, hotel room, classroom and external entrance all require different access decisions.
Handle, spindle, latch, lock case and cylinder dimensions must be compatible. This is one reason a bulk supply of complete door hardware sets should be approved through a hardware schedule and sample assembly.
Door-control products influence how far, how quickly or in which position a door moves.
Door closers return the door to the closed position. Stops prevent the handle or panel from striking a wall. Magnetic holders keep a door open where permitted by the application.
These accessories may appear secondary, but they protect the door, wall and primary hardware from repeated impact. Fire and smoke-control doors require particular attention because holding them open may be restricted or require approved release systems.
Protective products reduce damage caused by traffic and repeated contact.
Examples include:
kick plates;
push plates;
edge guards;
finger-protection devices;
wall buffers;
door stops.
The selection depends on the building. A service corridor may need more protection than a private bedroom, while a hospital or school may need hardware that tolerates frequent trolley or equipment movement.
Double doors and inactive leaves often require additional hardware. Flush bolts can secure the inactive leaf at the top and bottom. Coordinators may control the closing sequence where two fire-door leaves must close in the correct order.
Security chains, guards and specialist bolts may also be used where the door function demands them.
Door signs identify toilets, changing rooms, cloakrooms, accessible facilities and staff-only areas. They should be visible, consistently positioned and appropriate for the intended users.
Our door accessories category includes magnetic door stops and different identification signs for commercial and public interiors.
Each door should have its own hardware set. A simple schedule may record:
door number;
room function;
door and frame material;
hinge model and quantity;
handle or pull type;
latch or lock function;
cylinder requirement;
closer;
stop or holder;
finish;
special compliance notes.
This prevents a common procurement problem: the handles arrive in one finish, hinges in another, and the required latches or fixings are missing.
We manufacture lever handles, pull handles, door knobs, hinges, concealed hinges, stops and other architectural hardware. Our engineering team can modify existing products or develop new products to match supplied specifications.
Quality control monitors production, and on-site management coordinates orders and delivery. This supports a more consistent bulk supply of complete door hardware sets for distributors, door factories and project procurement.
Send us the door schedule, quantities, required functions, materials, finishes and project market. We can identify which products can be combined into coordinated sets and which details still require confirmation. Click here to discuss your hardware list with our team.
