STRUCTURAL TIMBER CONNECTORS / CONCEALED & INTERNAL FLANGE JOIST HANGERS

Simpson Strong-Tie SAI380/90 Heavy Duty Internal Flange Hanger (90mm x 145mm)

The Simpson Strong-Tie SAI380/90 (SAE380/90/2) is an industrial-grade, heavy-duty face fix joist hanger engineered with inward-turned internal fixing flanges to deliver a sleek, concealed finish. Designed specifically for securing 90mm wide solid sawn timber joists, glulam, LVL, and deep engineered wood members, this structural connector is ideal for tight corner joints, boundary positions, or applications where external flanges would interfere with adjacent cladding or structures. Manufactured from 2.0mm thick pre-galvanised steel, it features a generous 76mm seat depth and pre-punched fastener patterns for high shear load capacities across floor framing and structural timber connections.

RECOMMENDED INSTALLATION FASTENERS

To achieve published structural load values and satisfy UK building control regulations, the SAI380/90 must be installed using specified 3.75x30mm square twist nails or CNA connector nails. Ensure all header and joist nail holes are filled as required by the structural layout specification. Note: Internal flange (SAI) hangers are not recommended for structural bolted applications.

KEY STRUCTURAL PERFORMANCE ADVANTAGES

  • Concealed Internal Flanges: Turn inward to hide fixing flanges completely behind the carried member, creating an aesthetically clean finish and allowing joists to flush up tightly against walls or adjacent corner framing.
  • Heavy-Duty 2.0mm Construction: Engineered from thick G275 pre-galvanised steel to handle high downward and shear loads in heavy timber structures.
  • Generous 76mm Bearing Seat: Delivers maximum support area for the incoming joist, reducing localized timber crushing stress and boosting joint stability.
  • Fully Building Code Certified: ETA and UKCA compliant to maintain strict structural compliance across commercial and residential timber frame assemblies.

How We Keep Your Builds Moving

We partner with leading heavy industrial parcel and parcel-freight carriers across the country to maintain real-time tracking from our central warehouse shelves straight to your signature pad.

01.
Instant Hub Sorting: Approved orders pass straight to active pick queues via our localised automated barcode stock framework.
02.
Heavy Component Packing: Structural products are safely stored in industrial reinforced crates or strapped securely to custom pallets to fully safeguard fine threads and anti-corrosion zinc surfaces.

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.
