Simpson Strong Tie RPBZ Retrofit Steel Post Base

Product Description

The SIMPSON STRONG TIE RPBZ is a retrofit steel post base designed to anchor vertical posts in both new construction and retrofit applications. Fabricated from ZMAX galvanized steel with a hot-dip galvanized finish, it delivers strong corrosion resistance in exposed outdoor environments. The base provides a stable, code-compliant connection point between structural posts and concrete or treated lumber substrates. Installation is straightforward for carpenters, deck builders, and general contractors working on residential and light commercial projects.

The RPBZ is suited for deck posts, fence posts, and other vertical structural members in outdoor settings. Its retrofit design allows it to be installed on existing concrete pads or footings without requiring formwork modifications. The ZMAX galvanized coating makes it appropriate for ground-contact and pressure-treated lumber applications where standard galvanizing may not provide adequate protection against accelerated corrosion.

Key Features

• ZMAX galvanized steel construction for enhanced corrosion resistance in harsh outdoor environments
• Hot-dip galvanized finish compatible with ACQ and other pressure-treated lumber types
• Retrofit design allows installation on existing concrete without full formwork
• Suitable for residential and commercial deck, fence, and vertical post applications
• Sold in packages of 12 units (unit of measure: EA)

Compatibility

Designed as an OEM-style replacement and retrofit solution for standard steel post base applications in residential and commercial structural framing. Consult the SIMPSON STRONG TIE load table documentation for specific post sizes and load ratings before installation.

Installation Notes

Installation is typically performed by licensed contractors or experienced carpenters following local building codes and the applicable provisions of the IBC or IRC. Ensure the concrete footing or slab is fully cured before anchoring the base. All fasteners should be compatible with ZMAX galvanized hardware to prevent galvanic corrosion. Do not substitute standard zinc-plated fasteners when installing in ground-contact or high-moisture environments.
