Choosing Hinges, Locks and Hardware for Custom Metal Doors

t490-19

Custom metal door hardware should be chosen by door weight, use, security level and finish, then coordinated with the frame and wall construction from the start. Specify hinges, locks and closers together in one hardware schedule so each component is sized and fixed to suit the door it serves.

Start with the door's weight and use

Before selecting any hinge or lock, define how the door will be used. A heavy steel entrance door opening to a busy stair lobby places very different demands on hardware than a light interior door in a private house. Door weight, width and height determine how many hinges are needed and what load rating they must carry.

Ask whether the door is single or double leaf, whether it swings in or out, and how often it will be opened. High-traffic doors call for heavy-duty bearings and reinforced fixing points, and these decisions are best made early in the design stage.

Hinge types and how to place them

Hinges for custom metal doors are commonly butt hinges, bearing hinges or concealed pivot systems, depending on the look and the load. Concealed options suit minimal architectural detailing, while visible heavy hinges can be a deliberate design feature.

Confirm the number of hinges based on door height and weight.
Align hinge knuckles so the door sits square in the frame.
Plan reinforcement plates in the leaf and frame at each fixing point.

Locks, latches and security levels

Lock selection depends on whether the door is an entrance, a service door or an internal room door. Mortise locks, multipoint systems and electric strikes each suit different situations, and each requires a cut-out or cavity sized correctly in the metal leaf.

Discuss security requirements with the client early. A door that must resist forced entry needs a stronger frame, hardened fixings and a compatible lock body. Locks should always be specified by model and handing so that the factory can prepare the door accurately.

Closers, stops and door controls

Door closers protect the frame, keep fire-rated doors closed where required and control the speed of opening. Floor springs, overhead closers and concealed arms each have distinct installation needs and affect the clear opening width.

Include door stops and holders in the schedule as well. Where a door must stay open during the day, an electromagnetic holder linked to the fire alarm may be appropriate. Confirm all fire and access requirements with the relevant engineer or consultant before finalising the schedule.

Finish, corrosion protection and compatibility

Hardware must suit the door finish and the environment. Exposed exterior doors benefit from stainless steel or corrosion-resistant components, while interior doors may use standard finishes matched to the design palette. Mixing metals without care can cause galvanic corrosion, so compatibility matters.

Coordinate hardware finishes with the powder coating or galvanizing applied to the door, so that handles, escutcheons and visible fixings look consistent across the project.

Coordinate with the factory and site

The most reliable results come from sharing a complete hardware schedule with the metalwork manufacturer before production. The factory needs exact hinge positions, lock cut-outs, closer mounting details and cable routes for electric hardware. Late changes after fabrication are costly and can weaken the door.

Measure the opening on site, confirm wall construction and check that the frame is plumb and square. A short coordination meeting between architect, installer and manufacturer usually prevents most problems at installation.

Frequently asked questions

How many hinges does a custom metal door need?

The number depends on the door's height, width and weight, and on how often it is used. Heavier or taller doors normally need more hinges, and the manufacturer can confirm the right count for your specific door.

Should hardware be specified before or after fabrication?

Hardware should be specified before fabrication, because the factory must prepare cut-outs, reinforcement and fixing points in the metal. Changing hardware after production often requires modification or replacement of the leaf.

Can stainless steel hardware be used on galvanized doors?

It can, but the combination of metals should be checked to avoid galvanic corrosion, especially outdoors. Confirm the compatibility with the manufacturer and choose suitable insulating washers or finishes where needed.

Who decides the security level of a door?

The architect or designer should define the security requirement together with the client, based on the building's use and risk. The lock, frame and fixings should then be specified to meet that requirement.

Common mistakes to avoid

Specifying hardware separately from the door design often leads to wrong cut-outs, weak fixings or mismatched finishes. Leaving the hardware schedule until late in the project is one of the most common causes of delays on site.

Our recommendation

Prepare a single hardware schedule listing every hinge, lock, closer and accessory by model, finish and handing, and send it to the metalwork manufacturer before fabrication begins. Review it together with the frame and wall details to confirm that all components fit and function as one system.

Summary

Choose custom metal door hardware by considering weight, use, security, finish and frame coordination, and lock the full schedule before production. Early coordination with the manufacturer prevents costly changes and ensures a durable, well-fitting door.
