Ironmongery Specification Guide: Architectural Hardware for Construction Buyers

Architectural ironmongery covers more than door handles. A residential development specification typically runs to several hundred SKUs across doors, windows, cabinetry, and ancillary fittings; commercial projects can exceed a thousand. Knowing how to break a project ironmongery schedule into supplier-aligned categories is the first step toward an efficient procurement process.

The categories we routinely manufacture from Aligarh: door lever handles and pull handles, door knobs, escutcheons and thumb-turns, tee hinges and band-and-hook gate hinges, Suffolk latches and thumb latches, tower bolts and door bolts, letter plates, numerals, door knockers, cabin hooks, window stays and fasteners, hat and coat hooks, curtain hardware, railing components, and ancillary brass fittings. In UK trade language this splits into door furniture — the visible items like handles, knobs, knockers, and letter plates — and the working ironmongery of hinges, bolts, and latches behind them. We supply both, as decorative and standard-duty hardware.

UK and European door furniture follows well-established dimensional conventions, and matching them is what makes imported hardware drop straight onto a UK door leaf without remedial work. Standard residential lever handle dimensions: 8mm square spindle, 38–45mm rose diameter for compact roses, 50–60mm rose diameter for larger decorative roses, 175–200mm overall lever length. Standard hinge sizes: 75mm, 100mm, 102mm, and 125mm leaf lengths. Tee hinges for gates and ledged doors run 100mm to 600mm; letter plates typically 250 x 75mm or 300 x 75mm.

Confirm dimensional alignment with your project specification early — small mismatches between architect specifications and manufacturer standards are a frequent cause of remedial work on site. Where a drawing exists, attach it to the RFQ; where it doesn't, reference a sample piece and we reverse-match it.

A scope note for specifiers: our range is decorative and standard-duty ironmongery — door furniture, hinges, latches, bolts, and window fittings. Where a commercial schedule includes performance-graded or fire-certified positions, those items sit outside our range; buyers typically split the schedule, sourcing certified positions from a tested-hardware line and the visible door furniture from a manufacturer like us, with finishes matched from approved samples across both sources.

Architectural ironmongery finishes serve both aesthetic and protective purposes. The standard finish palette covers polished brass, brushed brass, antique brass, satin nickel, polished nickel, brushed nickel, satin chrome, polished chrome, matte black powder coat, oil-rubbed bronze, and the PVD family (rose gold, champagne gold, gun metal, black gold). BHMA finish codes are widely used by US-market specifiers; RAL colour references for powder-coated finishes by European specifiers.

For projects where multiple ironmongery categories must finish-match — door handles, hinges, escutcheons, window furniture, cabinet hardware all in the same finish — single-batch production matters. We schedule finish runs to ensure all components for one project pass through the same finishing batch where possible, eliminating cross-batch tonal variation that becomes visible when components are installed side-by-side.

The ironmongery schedule is the document that turns a project specification into a manufacturable order. It lists hardware door-by-door: every opening gets a reference, and every item on that opening gets a line — item, size, finish, and quantity. Compiled properly, it does three jobs at once: quantities roll up per SKU so the quote and MOQ alignment are accurate, finishes stay consistent across every category on the schedule, and phased deliveries can be packed by floor or zone instead of by SKU.

The minimum workable columns, in the order most UK specifiers use them:

Standard ironmongery MOQ guidance: lever handles, pull handles, hinges — 200 pieces per SKU. Escutcheons, thumb-turns, ancillary accessories — 300–500 pieces per SKU. Custom-tooled SKUs — 500+ pieces to amortise tooling. Project orders covering multiple SKUs can be combined; a 10,000-piece project order across 20 SKUs is treated differently from 20 separate 500-piece orders.

For builders merchants and distribution buyers maintaining inventory, the most commercially intelligent approach is to consolidate annual requirement into 2–4 production batches per year — this maintains inventory turnover without sacrificing per-piece economics. Speak to us about annual contract pricing arrangements; we offer favourable terms to distributors with predictable repeat volume.

Construction-sector packaging differs from retail packaging. The priority is product protection in long-distance freight, traceability through the supply chain to site, and ease of handling at the installation point. Standard configuration: each piece in an inner poly-bag with foam protection on machined faces, grouped by SKU into branded inner cartons, then aggregated into master export cartons.

For buyers operating an SKU-coded warehouse system, master cartons can be labelled with EAN/UPC barcode or buyer-specified internal SKU codes to support automated stock receipt. For project deliveries direct to site, packing can be organised by floor, zone, or work package rather than by SKU type. Specify your downstream requirement at RFQ stage so packing is configured correctly from the production floor.

Standard catalogue ironmongery in standard finishes: 18–28 days from order confirmation. Custom-tooled SKUs: add 14–28 days for tooling and sampling. Fire-rated test certification, where required: add 4–6 weeks. Sea freight from JNPT to UK and European ports: 22–28 days; to North American East Coast: 30–38 days; to UAE Jebel Ali: 7–10 days; to Australian east coast: 26–32 days.

For project ironmongery requiring delivery aligned to construction schedule, partial shipment is supported across multiple dispatches — doors and windows in phase one, fitted furniture ironmongery in phase two, ancillaries in final phase. This eliminates site storage burden and matches hardware arrival to install sequence.
