STRUCTURAL TIMBER CONNECTORS / ELEVATED POST BASES

Simpson Strong-Tie PPA100 Elevated Post Base (100mm Stand-Off)

The Simpson Strong-Tie PPA100 is an engineered, industrial-grade elevated post base designed for structural timber installations requiring a fixed, clean stand-off ground clearance. Manufactured from heavy-duty structural steel, it provides a stable 100mm elevated distance that effectively isolates the base of timber columns from standing water and concrete sub-slab capillary draw. Highly specified for outdoor framework such as awning posts, pergolas, verandas, porch-ways, and car-ports, this support eliminates the need for complex timber machining or pre-slotting, allowing direct and rapid structural connection to solid wood, composite lumber, or glue-laminated (Glulam) columns.

CRITICAL STRUCTURAL SPECIFICATION: LATERAL RESTRAINT MANDATE

Like all standard stand-off structural supports, the PPA100 operates strictly as a pinned structural connection. It is engineered exclusively to resist vertical axial loads, downward compression, and horizontal shear forces—it is not designed to withstand bending moments or rotational momentum. To maintain structural integrity, the top of the timber post must be rigidly secured via an approved lateral restraint configuration (such as floor diaphragms, cross-bracing, or braced beam structures).

TECHNICAL DATA & DESIGN CAPACITIES

Specification Parameter Engineered Values & Materials
Base Plate Dimensions 130mm x 130mm square footprint
Stand-Off Ground Clearance 100mm fixed isolation clearance
Material Composition Premium S235JR grade mild steel plate array (NF EN 10025 certified)
Corrosion Protection Grade Heavy 50 µm Hot-Dip Galvanised coating (NF EN ISO 1461 optimized for Service Class 3 exterior exposures; EN 15804 EPD certified)
Characteristic Capacities R1,k (Downward Axial Compression) = 93.2 kN (C24 structural timber column configuration)
Fastener Requirements (Timber) Requires 4 No. structural coach screws (e.g., SSH10x60mm to SSH10x75mm into timber end grain; 4 No. Ø12mm flange holes provided)
Fastener Requirements (Concrete) Requires 4 No. M10 structural concrete anchors (e.g., SET-XP or AT-HP dependent on spacing; 4 No. Ø12mm base anchor holes provided)

KEY STRUCTURAL PERFORMANCE ADVANTAGES

  • High-Capacity Axial Load Resistance: Engineered heavy-gauge steel column configuration delivers an outstanding characteristic compression capacity of 93.2 kN.
  • No Timber Machining Needed: Top plate mounts flush against the square post face using end-grain structural screws, completely eliminating router cutting or boring on-site.
  • Industrial Hot-Dip Galvanised Shield: Thicker 50 µm zinc layer provides maximum anti-corrosion tracking guards under punishing outdoor Service Class 3 environmental conditions.
  • Certified Structural Integrity: Built to rigid EN guidelines with full CE approval and ETA documentation (ETA 503) for audited structural performance verification.

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.
03.
Tailgate On-Site Offloading: Bulk shipments drop cleanly at your structural site boundary line via integrated tail-lift carrier transport systems.

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.
