Lumber, structural hardware, fasteners, and accessories. Price fields are editable — type your vendor numbers in and the running totals recalculate live. Saved in your browser only.
How to use. Edit any unit price; the line total (qty × price) and the grand total at the bottom recalculate automatically. Edits save to your browser's localStorage. Lumber prices are from Ashby (2026-07-11). Hardware/fastener/roofing prices are public list prices from Home Depot and Amazon, scraped 2026-07-11; treat as a ballpark and verify at the register — especially the Suntuf panels, sealer, and shades, where scraping was blocked and I used my best estimate. Post base: Simpson APVB44 from the Outdoor Accents Avant collection (ZMAX with black powder coat). LSSJ26Z and H2.5A hurricane ties stay as standard ZMAX because the Avant collection has no slopeable hanger or hurricane tie equivalent.
1. Lumber

2. Structural Hardware
Simpson Strong-Tie (or equivalent) connectors in black powder coat to match the "exposed decorative hardware" aesthetic. APVB44 Avant post bases ship with their own fastener kit (4× SDWS22312DBB + 4× STN22 per base); only the concrete anchor and EPDM closure are separate. The LSSJ26Z and H2.5A stay as standard ZMAX because the Avant collection has no slopeable hanger or hurricane tie equivalent.

Field-check before ordering. Verify the APVB44 concrete anchor diameter matches what's available locally (⅝" Simpson Titen HD is what Simpson calls out; ½" wedge anchors work as a substitute but are slightly under-spec for the APVB44's rated load). Confirm the polycarbonate panel rib profile matches the local supplier's stock (Suntuf and Tuftex corrugated profiles differ — check the panel spec against the closure strip profile before buying). Confirm the tinted/gray color choice is in stock at your local HD (special order adds a week and a 15-20% premium).
