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, butt hinges (BS EN 1935 grade), parliament and projection hinges, mortice locks and rim locks, door closers (selected models), letter plates, numerals, door knockers, window stays and fasteners, casement and espagnolette handles, friction hinges, curtain hardware, railing components, and ancillary brass fittings.

For UK and European market buyers, the relevant ironmongery standards are BS EN 1906 (mechanically operated lever handles and knob furniture), BS EN 1935 (single-axis hinges), BS EN 12209 (mortice locks), and BS EN 1154 (door closers). These standards specify dimensional limits, performance grades, fire-rating compatibility, and corrosion resistance cycles. For US, Canada, and Mexican market buyers, the ANSI/BHMA series governs the same categories.

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 butt hinge sizes: 75mm, 100mm, 102mm, and 125mm leaf lengths in 2mm and 3mm leaf thickness. 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.

Test certification (where required for fire-rated assemblies or performance-graded ironmongery) is arranged through third-party labs with cost passed through transparently. Confirm certification requirements at RFQ stage rather than at QC stage; certification adds 4–6 weeks to lead time if not pre-arranged.

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.

Commercial, hospitality, and multi-residential projects increasingly require fire-rated and performance-tested ironmongery on critical doors. In the UK and Europe, this typically means BS EN 1634-1 fire test certification covering the complete door assembly including hinges, lock, and closer. In the US and Canada, UL 10C and CAN/ULC-S104 certification cover the equivalent.

For fire-rated ironmongery, we manufacture to specification but the certification belongs to the door assembly tested with our hardware installed. Coordinate certification at the door manufacturer level — most commercial door manufacturers maintain a list of certified hardware partners, and our hardware can be added to that list with testing.

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.
