The Simpson Steel Column Cap (No Straps) delivers a high-capacity connection for column-to-beam combinations where welding to a steel column is the preferred method. Engineered specifically without column straps, this cap is designed for direct field welding to a steel column end plate, creating a clean, structurally sound transfer point between the column and a 5.25 in. LVL, PSL, or LSL engineered wood beam. Self-tapping screws are included, so installation to the column end plate can begin immediately on the job site.

Key Features

• Adequate bearing length for larger girder reactions - handles heavier loads at the column-to-beam connection, reducing the risk of overstressing the bearing area on demanding structural applications.
• Compatible with both solid sawn lumber and engineered wood products - gives builders and engineers flexibility to use the right beam material for the project without sourcing a different connector.
• Self-tapping screws included - attachment to the column end plate can proceed right away using a 5/16 in. hex driver, saving time and an extra trip to the supply house.
• 7-gauge steel construction - the heavier gauge provides the structural rigidity and load capacity expected in commercial and residential column-to-girder connections.
• G90 zinc galvanized coating - a recognized industry standard for corrosion resistance, helping the connector hold up in exposed or demanding environments over the long term.
• No-strap design built for steel column welding - eliminates hardware that is unnecessary for welded steel column applications, simplifying the connection and reducing potential points of conflict during installation.

Why This Product

• Purpose-built for steel column applications - the strap-free design was created specifically for field welding to a steel column, meaning the connector fits the workflow of steel-framed construction without modification or workarounds.
• Everything needed for column-plate attachment is in the box - the four included self-tapping screws mean the cap goes from packaging to column end plate without hunting down additional fasteners, keeping the installation moving efficiently.
• Heavy-duty capacity where beams carry the most load - the seat geometry provides adequate bearing length for larger girder reactions, making this cap a practical choice when engineered wood beams are transferring significant structural loads to a column below.
• Corrosion-resistant finish extends service life - the G90 galvanized coating helps protect the connector in conditions where moisture exposure is a concern, supporting long-term structural integrity at this critical connection point.

Frequently Asked Questions

What type of column is the CCOS5.50 designed to be used with?

The CCOS5.50 was designed specifically for field welding to a steel column. It does not include column straps, making it ideal for steel column applications where welding is the preferred attachment method.

What beam or member size is the CCOS5.50 compatible with?

The CCOS5.50 is compatible with 5.25 in. LVL (Laminated Veneer Lumber), PSL (Parallel Strand Lumber), and LSL (Laminated Strand Lumber) engineered wood products, with a seat width of 5-1/2 in.

How is the CCOS5.50 attached to the column and the girder?

Attach the steel column cap to the column end plate using the (4) included self-tapping screws with a 5/16 in. hex driver. Attach the cap to the girder using 0.148 in. x 3 in. nails.

What corrosion protection does the CCOS5.50 have?

The CCOS5.50 features a G90 zinc galvanized coating, which provides reliable corrosion resistance for demanding structural applications.
