The Simpson CCOS Steel Column Cap provides a high-capacity connection for column-to-beam combinations in structural framing applications. This strap-free design was created specifically for field welding to a steel column, making it the right choice when traditional strap-based attachment methods are not applicable. The cap accepts 3.5 in. LVL, PSL, and LSL engineered wood members and is built from heavy 7-gauge steel with a G90 galvanized finish for lasting corrosion resistance. Four self-tapping screws are included so installation to the column end plate can begin immediately on the jobsite.

Key Features

• Adequate bearing length for larger girder reactions - distributes load effectively at the column-to-beam connection, supporting demanding structural assemblies without overstressing the seat.
• Designed without column straps for field welding - simplifies the connection at a steel column end plate, eliminating components that are unnecessary in welded steel-column applications.
• Compatible with LVL, PSL, and LSL engineered wood members - gives structural framers the flexibility to use the cap with a range of engineered wood products sized at 3.5 in.
• Sized also for solid sawn lumber applications (other CCOS options) - the CCOS product family spans both solid sawn and engineered wood members, so contractors can source a consistent connector across different project types.
• Self-tapping screws included - allows the cap to be secured to the column end plate right away, reducing the need for separate hardware runs and speeding up installation.
• 7-gauge steel construction - the heavy steel gauge delivers the structural rigidity required for high-capacity column-to-beam connections in load-bearing framing.
• G90 zinc galvanized coating - provides robust corrosion resistance, helping the connector maintain structural integrity over time in conditions where bare steel would degrade.

Why This Product

• Built for steel-column field welding - unlike strap-based column caps, the CCOS was engineered specifically to be welded directly to a steel column, making it a purpose-built solution rather than a workaround for steel-column framing scenarios.
• Faster installation right out of the box - the four included self-tapping screws and compatibility with a standard 5/16 in. hex driver mean the cap attaches to the column end plate without hunting down additional hardware, keeping the job moving.
• High-capacity performance for demanding beam loads - the combination of 7-gauge steel construction and adequate bearing length means the CCOS is sized to handle larger girder reactions that lighter-duty connectors are not designed to accommodate.
• Corrosion-resistant finish for long-term structural reliability - the G90 galvanized coating protects the steel connector against corrosion, supporting the long service life expected of a structural column-to-beam connection.

Frequently Asked Questions

What type of column is the CCOS3.62 designed to attach to?

The CCOS3.62 is designed specifically for field welding to a steel column. Its strap-free design makes it the appropriate choice when welding to a steel column end plate rather than using traditional strap-based attachment methods.

What fasteners are required to install this column cap, and are they included?

To attach the column cap to the column end plate, four self-tapping screws (included) are used along with a 5/16 in. hex driver. To attach the cap to the girder, 0.148 in. x 3 in. nails are required.

What beam sizes and wood types is the CCOS3.62 compatible with?

The CCOS3.62 is sized for 3.5 in. engineered wood members, specifically LVL (Laminated Veneer Lumber), PSL (Parallel Strand Lumber), and LSL (Laminated Strand Lumber). Simpson Strong-Tie also offers CCOS sizes for both solid sawn lumber and other engineered wood products.

What corrosion protection does the CCOS3.62 offer?

The CCOS3.62 features a G90 zinc galvanized coating, which provides a robust level of corrosion resistance suitable for structural column-to-beam connection applications.
