STRUCTURAL TIMBER CONNECTORS / ADJUSTABLE POST BASES

Simpson Strong-Tie PPRC Adjustable Elevated Post Base

The Simpson Strong-Tie PPRC is an innovative, heavy-duty adjustable structural timber post support engineered to allow precise leveling modification even after the structure has been fully built and installed. Highly popular for architectural framing, awning posts, pergolas, and verandas, this support provides an off-the-ground stand-off isolation zone that is adjustable from 100mm to 150mm. Designed to work seamlessly with solid wood, composite lumber, and glued-laminated (Glulam) timber columns from 100x100mm up to 200x200mm, it requires absolute zero timber machining or pre-boring, saving crucial installation time while offering lifetime adjustment capabilities.

CRITICAL STRUCTURAL SPECIFICATION: LATERAL RESTRAINT MANDATE

Like all standard stand-off structural supports, the PPRC operates strictly as a pinned structural connection. It is engineered exclusively to resist vertical axial loads and downward compression 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).

KEY STRUCTURAL PERFORMANCE ADVANTAGES

  • Post-Installation Level Adjustment: Unique engineering allows full vertical alignment and leveling adjustments ranging from 100mm to 150mm even after the main timber frame is resting on the base.
  • Zero Machining Needed: Completely eliminates complex wood cutting, routering, or center-fin slotting on columns, streamlining trades on-site.
  • Dichromate Shield Array: Enhanced dichromate coating over a galvanised base plate system delivers long-lasting protection against environmental degradation under Service Class 2 rules.
  • Regulatory Compliance Standards: Fully ETA and CE certified component, delivering a guaranteed uniform character capacity profile of up to 57.1 kN compression loading.

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.
