Simpson Post Bases & Column Bases Walkthrough

Post Bases & Column Bases

Bases are crucial post brackets used for anchoring posts and columns to the ground or other structures, providing stability and support. Post bases are typically for smaller, lighter posts, while column bases are for larger, heavier columns that support bigger structures.

Post Bases

Post bases securely anchor posts to the ground or a concrete base, ensuring stability and resistance to lifting and sideways movement. They are commonly used in building decks, pergolas, and other outdoor structures, helping to prevent damage from moisture.

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.
