STRUCTURAL TIMBER CONNECTORS / CONCEALED BEAM HANGERS

Simpson Strong-Tie BTALU90-B Concealed Aluminium Hanger

The Simpson Strong-Tie BTALU90-B is a premium structural connecting system engineered to deliver high-capacity load resistance while maintaining a completely hidden, aesthetically pristine architectural finish. Specifically engineered for feature beam networks and exposed Glulam framing, this invisible hanger consists of a single-piece extruded aluminium body with a dedicated rear mounting flange and a prominent central vertical fin. The plate is secured directly flush to the carrying header timber before being slotted into a pre-cut core layout inside the incoming joist. Locked reliably in position with heavy-duty structural steel dowels, the BTALU system eliminates external ironwork visibility while guaranteeing exceptional joint rigidity across demanding engineering spans.

CRITICAL STRUCTURAL APPLICATION & SPECIFICATION MANDATE

The BTALU90-B configuration mandates strict technical adherence to structural sizing guidelines on-site. This bracket requires a minimum incoming joist height threshold of 142 mm to allow full slot containment. To execute installation, secure the flat base section onto the main header beam using approved CNA 4.0 x 50mm connector nails or CSA connector screws. Once fixed, slide the vertical fin cleanly inside the matching slot cut along the center line of the supported timber joist. Pre-drill corresponding dowl holes smoothly through the wood and the alignment tracks of the internal aluminium fin, then complete the structural integration by passing the selected steel dowels firmly through the layout.

KEY STRUCTURAL PERFORMANCE ADVANTAGES

  • Architecturally Concealed Profile: Bypasses traditional external side-flange visibility, keeping the metal connector entirely inside the joint for uncompromised timber detailing.
  • Lightweight Aluminium Build: Forged from extruded aluminium to create an optimal strength-to-weight ratio, facilitating hassle-free manual installation overhead.
  • Accurate Dowel Alignment: Pre-bored pilot guidelines along the inner fin allow accurate drilling and fast structural integration under challenging site conditions.
  • Tested Glulam Performance: Thoroughly calculated and evaluated by structural specialists to support heavy residential and commercial engineered timber frameworks.

Logistics Scope & Out-Of-Zone Shipments

Standard pricing arrays map explicitly to structural mainland UK postal grids. Supplementary transit routing variables, variable lead times, or specialised carrier adjustments apply across high-altitude or outlying maritime zones:

  • Scottish Highlands & Islands: Postcode structures matching KW, IV, PA, and PH configurations map to premium alternative transit grids. Please review checkout calculations for accurate real-time weights.
  • Northern Ireland, Isle of Man & Outer Channels: Specialised water-crossing logistical paths require clean custom manifesting lines.
  • Heavy Oversized Pallets: Extended multi-ply girder connectors, structural space straps, or high-volume masonry hangers exceeding standard bulk dimensions pass through dedicated heavy haulage grids.
*** NEED SPECIFIC AM DELIVERY TIMES OR SITE COORDINATION ARRANGEMENTS *** If your project features demanding time windows, unique site restrictions, or crane offload coordination, contact our central logistics team directly on 01707 375172 or email your schedule over to finalise arrangements.
