Simpson Post Brackets Product Walkthrough

Post bracket connectors, encompassing various caps and bases, are crucial in building wooden structures like decks, porches, and fences. They are vital for ensuring the longevity and robustness of these constructions.

Enhancing Structural Integrity

Post caps and bases significantly enhance the strength and stability of connections between posts and beams in wooden structures. They provide crucial support against shear loads and tension, which is essential for maintaining the structural integrity of constructions such as decks, fences, and pergolas.

Preventing Moisture Damage & Decay

Post caps and bases act as a critical barrier for the tops and bottoms of posts, protecting them from water penetration. This helps prevent rot and mold growth, which can severely weaken wood over time.

Types of Post Brackets

Post brackets generally fall into two categories: bases and caps. Bases secure posts and columns to the ground or other structures, while caps attach to the tops of posts or columns. Below, we explore each type in more detail.

Bases

Bases are essential components that anchor posts and columns to the ground or other structures, providing stability and support. Post bases are typically used for smaller, lighter posts, whereas column bases are designed for larger, heavier columns that support significant structures.

Post Bases

Post bases are designed to anchor posts securely to the ground or a concrete base, ensuring stability and resistance to uplift and lateral forces. Commonly used in the construction of decks, pergolas, and other outdoor structures, these bases help prevent moisture-related deterioration.

Types of Post Bases

  • Retrofit Post Bases: Installed after the concrete foundation has set and cured.
  • Cast-in Place Post Bases: Installed in the formwork, with concrete poured around them, embedding the base once set.
  • Fence Post Bases: Specifically designed for fence posts, often with unique features for this application.
  • Decorative Post Bases: Black powder-coated bases that enhance the aesthetic appeal of outdoor structures.
