Door Ironmongery: The Details That Make a Building Work

Ironmongery might seem like a minor detail compared to structural steelwork or concrete foundations, but walk into any building and the first thing you interact with is a door handle. Getting ironmongery counts wrong leads to incomplete door sets, delayed handovers, and frustrated fit-out teams. The Door Ironmongery Count Estimator on ToolWard generates a complete ironmongery schedule from your door schedule, ensuring every handle, hinge, closer, lock, and accessory is accounted for before you place a single order.

What This Estimator Produces

The Door Ironmongery Count Estimator takes your project's door schedule - listing each door by type, size, function, and fire rating - and produces a comprehensive ironmongery count. For each door type, it lists the required items: hinges (typically three per door, four for heavy or fire-rated doors), handles or lever sets, locks or latches (mortice deadlocks, cylinder locks, bathroom turns, or passage latches depending on function), door closers (required on all fire doors), kick plates, letter plates, numerals, signage, and hold-open devices or magnetic releases where specified.

How to Use the Door Ironmongery Count Estimator

Begin by defining your door types. A typical commercial project might have single-leaf fire doors, double-leaf corridor doors, entrance doors with access control, bathroom doors with privacy locks, and plant room doors with heavy-duty hardware. For each type, specify the quantity on the project and the ironmongery items required per leaf.

The tool allows you to configure ironmongery sets - predefined combinations of items that apply to a door type. For example, a standard office door set might include one pair of lever handles, three butt hinges, one mortice latch, and one overhead closer. A fire door set adds an intumescent strip, smoke seal, and self-closing device. Once you've set up these templates, the estimator multiplies through your quantities and presents a consolidated shopping list.

The output groups items by product type rather than by door, making it easy to place orders. Instead of seeing that door type A needs 3 hinges and door type B needs 4, you see the total hinge count across the entire project - ready for your supplier quote.

Who Needs an Ironmongery Schedule?

Architectural practices produce ironmongery schedules as part of their detailed design documentation. The Door Ironmongery Count Estimator streamlines this process, especially on large projects with dozens of door types. Main contractors use ironmongery schedules for procurement, placing bulk orders that achieve better pricing than ad hoc purchases. Door set manufacturers need accurate ironmongery lists to assemble complete door sets in the factory. Specialist ironmongery consultants use tools like this to verify their schedules against the architect's door schedule before issuing to the contractor.

Real Projects Where This Tool Saves Time

Consider a hospital construction project with 500 internal doors across 15 different types - from standard ward doors and fire escape doors to specialist laboratory doors and clean room entrances. Each type has a unique ironmongery specification, some with access control, some with vision panels, some with electromagnetic hold-open devices linked to the fire alarm. Compiling the total ironmongery requirement manually from a 500-row door schedule is a full day's work and highly error-prone. The Door Ironmongery Count Estimator reduces this to less than an hour of data entry followed by an instant, accurate output.

On the other end of the scale, a developer building 50 identical apartments needs ironmongery for 6 doors per unit - that's 300 doors. With just 3 or 4 door types across the entire project, the estimator produces the total requirement in minutes, giving the procurement team enough time to source competitive quotes rather than rushing last-minute orders.

Ironmongery Estimation Tips

Always include fixing screws and sundries in your count. Most ironmongery items come with fixings, but budget hardware might not. Check with your supplier whether screws are included or need separate ordering. The estimator includes a sundries allowance option for this purpose.

For fire-rated doors, ensure your ironmongery items are certified to the same fire rating as the door leaf and frame. Using non-fire-rated hardware on a fire door invalidates its certification - a serious compliance issue that building control inspectors will flag. The tool lets you tag fire-rated door types to remind you of this requirement.

Consider master-key suites early in the design process. Cylinder locks need to be ordered as part of a coordinated suite where a master key operates all locks while individual keys only operate their own. This affects procurement lead times significantly and should be factored into your programme.

Every Handle, Every Hinge, Every Door
