As a dedicated metal fabrication manufacturer, we engineer brackets for structural reliability, corrosion performance, and wholesale logistics efficiency.
Adjustable / Fixed / Raised / Concealed under unified specification & QC.
Slotted or threaded center adjustment compensates footing offset.
Raised standoff designs maintain air gap above concrete surface.
Finish matrix mapped to exposure classes (interior → coastal salt).
A post base bracket is a structural metal connector anchoring a vertical timber (or engineered wood) post to a concrete footing, slab, pier, or masonry surface. It commonly provides:
Variants include fixed, adjustable (slotted or threaded), raised (standoff), concealed (knife / internal), and heavy-duty seismic or high-load forms. It is distinct from a simple “post saddle” by engineered edge geometry, uplift retention features, or concealed load path hardware.
Indoor / Covered Dry: G90 (economical)
Standard Exterior / Deck: G185 / HDG
Pressure-Treated / High Moisture: HDG (thicker zinc) or Duplex for aesthetics
Coastal / Chloride / Marine: 316 stainless (primary) / 304 for moderate salinity
Architectural Appearance: Powder or Duplex (HDG + Powder)
High Chemical / Industrial: 316 + passivation report
* Provide your project drawings—we convert to manufacturable bracket specs.
Looking for more solutions.
Post base bracket emphasizes engineered load path (uplift, lateral) and moisture separation; a simple anchor may only locate the post.
By elevating the post end, capillary moisture uptake and surface pooling are reduced, extending service life when combined with proper sealing.
Not optimally; separate seat geometry preserves bearing and lateral restraint; adjustable multi-size compromises performance.
Use PB Adjustable Slot variant; tighten reference bolt first, then align and torque slotted side.
High chloride, splash zones, coastal decks, or chemical exposures where zinc lifespan is insufficient.
Duplex (HDG + powder) balances cost and appearance; 316 outperforms in harsh chloride cycles but at higher cost.
Yes (Duplex system) provided surface prep (sweep blast / passivation management) to ensure adhesion.
Yes—provide target kN; engineering review may adjust thickness, strap height, anchor spec, or gusset design.
