The Simpson BC60R BC Galvanized Post Base for 6x Rough is an 18-gauge steel post base from Simpson designed to securely anchor the bottom of a 6x rough-cut post or column to a wood deck or concrete surface. Built for light base applications in deck construction and patio cover installations, it delivers a positive, structurally reliable connection where angled nailing or screw fastening simply cannot match the holding strength. The G90 galvanized coating provides extra corrosion resistance, making this base well suited for the moisture-prone outdoor environments where post-to-structure connections are most critical.

Key Features

• Positive post-to-deck connection - creates a secure mechanical attachment at the base of the post, eliminating reliance on less reliable nailing techniques and giving the overall structure greater stability.
• Stronger than angled nailing or screw fastening - engineered to outperform common field methods, reducing the risk of connection failure under load in deck and patio cover applications.
• Reduces post splitting and eliminates end-grain nailing - the base design spreads fastening force away from vulnerable end grain, helping preserve the integrity of the post over time.
• Sized specifically for 6x rough lumber - matched to rough-cut post dimensions rather than standard dimensional lumber, ensuring a proper, snug fit without shimming or modification.
• Made from 18-gauge steel with G90 galvanized coating - the heavier zinc coating provides extra corrosion resistance compared to lighter finishes, extending service life in wet and outdoor settings.
• Intended for top-supported structures only - designed for decks and patio covers where the post is braced at the top, so buyers can confidently spec this base for the right application and avoid costly misuse in non top-supported installations like fences or unbraced carports.

Why This Product

• A more reliable connection than traditional field fastening - rather than depending on angled nails driven into end grain, this post base uses a formed steel seat that holds the post positively in place, reducing the chance of splitting and improving overall structural performance at the base connection.
• G90 galvanizing for long-term outdoor durability - the G90 zinc coating provides extra corrosion resistance, making this base a dependable choice for decks, patio covers, and other exterior applications where moisture exposure is a constant factor.
• Precise fit for rough-cut lumber avoids guesswork - because the BC60R is specifically sized for a 6x rough post rather than dressed dimensional lumber, contractors and builders get a proper fit from the start, saving time on the job and reducing the chance of an insecure installation.
• Domestically produced to Simpson quality standards - manufactured in the United States, this post base reflects the consistent dimensional accuracy and material quality that the BC series is known for in light-base post and column anchoring applications.

Frequently Asked Questions

What post size is the BC60R designed to fit?

The BC60R is designed for a nominal 6x rough post size, making it specifically suited for rough-cut lumber applications rather than standard dimensional lumber.

What fasteners should be used to install the BC60R?

Install with 16d commons or 16d x 2 1/2" joist hanger nails, as specified for the BC series post base.

Can the BC60R be used for fences or unbraced carports?

No. This post base is not recommended for non top-supported installations such as fences or unbraced carports. It is intended for top-supported structures like decks and patio covers.

Why is the G90 galvanized coating important?

The G90 galvanized coating provides extra corrosion resistance compared to lighter zinc coatings, helping the post base withstand moisture-prone outdoor environments such as decks and patio installations over time.
