An In-Depth Technical Guide for Specifiers, Architects, and Commercial Building Contractors
The architectural fabric of London represents a unique dynamic: combining historical Victorian, Georgian, and Edwardian structures with modern high-density steel-and-glass developments in Canary Wharf and the City. For architectural specifiers and interior design firms procuring solid wood staircases, balancing historical aesthetic authenticity with modern structural rigor is paramount.
As an established export-oriented timber manufacturer with over two decades of technical expertise, Nineteen Intertrade Co., Ltd. specializes in the direct-from-factory production of high-performance solid wood staircases, tread assemblies, handrail systems, and structural winders specifically engineered for the United Kingdom market.
Timber supplied to the UK must withstand severe seasonal moisture fluctuations. Standard tropical or Asian timber dried to 14-16% moisture content will shrink, cup, and creak under British central heating systems. Our specialized automated kiln-drying processes stabilize timber to an exact 8% to 10% Equilibrium Moisture Content (EMC), guaranteeing dimensional stability inside London homes.
Using advanced 5-axis European CNC machining centers, our factory translates CAD drawings into micron-accurate stair components. From complex winder steps to continuous helical handrails, every mortise, tenon, and housing joint fits seamlessly on site, drastically reducing labor installation costs for UK site contractors.
Under post-Brexit UK Timber Regulations (UKTR), London commercial developers require 100% legal timber traceability. We provide complete Chain of Custody (CoC) documentation for all solid wood species including Acacia, Teak, European Oak, and Rubberwood, ensuring flawless customs clearance at UK ports like London Gateway and Tilbury.
All solid wood staircases exported to the Greater London region are custom-manufactured to conform to UK Approved Document K (Stairs, ladders and ramps). For private domestic properties, our treads maintain a maximum pitch of 42°, with risers engineered between 150mm and 220mm, and goings between 220mm and 300mm. For public and commercial buildings in London, we supply open-riser systems fitted with 100mm gap-bar limiters to comply with mandatory safety codes for child entrapment prevention.
Tailored timber engineering solutions matching the structural and aesthetic requirements of distinct London boroughs.

Combining cost-efficient Asian raw material processing with world-class OEM customization and direct sea-freight logistics.
By bypassing intermediary traders, London contractors and importers save up to 35% on bespoke stair flights. Our 20,000+ sqm manufacturing facility in Bangkok handles everything from raw log sawing to final lacquering.
To eliminate onsite installation errors, every complex staircase is pre-assembled in our factory test tower. We provide 3D CAD modeling, component numbering, and HD video verification prior to packing into containers.
Stair components are packed using moisture-proof shrink wrap, reinforced edge protectors, and heavy-duty ISPM-15 heat-treated wooden crates. Direct container shipping routes from Bangkok to London Gateway reach destination in 28-32 days.
