The columns are protected with a corrosion-resistant finish and labeled for easy identification, meeting all relevant building code standards.
For aluminum columns, AFco provides round fluted, square fluted, and snap-together options in a variety of diameters and styles. These are often used in decorative applications and can be installed in both indoor and outdoor environments. The installation process for these columns requires careful alignment and securing to ensure structural integrity and visual appeal.
Installation of Structural Steel Columns
The installation of AFco’s structural steel columns involves several key steps, beginning with site preparation and ending with securing the column to the structure. The following steps are based on installation guidelines provided in official documentation and technical manuals.
1. Site Preparation and Measurement
Before installing a column, it is essential to ensure the site is prepared correctly. The installation should be on a smooth, level surface to prevent uneven settling or structural stress. Columns should be installed according to standard construction practices and in compliance with local, state, and federal regulations.
Measure the opening height where the column will be placed. This is important for determining the length of the column and ensuring it fits properly within the structural framework. For adjustable columns, it is recommended to subtract 1/8 inch from the measured height to account for compression and settling.
2. Assembling and Positioning the Column
Once the column is assembled, it should be placed into the upright base of the post. The top portion or capital is then slid over the assembled column and positioned at the base. It is important to use a level to ensure the column is plumb, or perfectly vertical. This step is critical for maintaining structural integrity and preventing future issues such as warping or uneven weight distribution.
Columns should not be used to support second-story balconies or other structures directly attached to the side of the column. This is a common installation error that can compromise the column’s load-bearing capacity and stability.
3. Securing the Column
To secure the column, use the appropriate anchoring fasteners, such as AFCO Column Hold Down Clips or AFCO Hurricane Installation Brackets. These fasteners are designed to provide a secure connection between the column and the floor or ceiling surface. The column should be attached to both the floor and ceiling to distribute the load evenly and prevent lateral movement.
For load-bearing applications, it is recommended to use AFCO load-bearing plates to spread the weight over the entire perimeter of the column. This ensures that the load is evenly distributed and minimizes the risk of structural failure. The load-bearing capacity of AFco columns is rated for up to 3,000 pounds, provided the installation follows the manufacturer’s guidelines.
4. Installing Decorative Elements
AFco offers a range of decorative capitals, wraps, and skirts that can be added to columns for aesthetic enhancement. These elements are typically installed after the structural components are secured.
To install a decorative capital, place it over the top of the column and slide it down until it rests on the base. Do not secure it immediately, as adjustments may be necessary to ensure proper alignment. The capital should be connected to the column using color-matching screws, with pre-drilled holes to prevent splitting or damage to the material.
For post wraps, measure the height of the column and cut the wrap to size, subtracting 1/8 inch to ensure a snug fit. Align and connect the four sides of the wrap, snapping them together around the structural post. Compress the two halves together until the cover fits securely. Post skirts can be added at the top and bottom of the column for a finished look.
Technical Specifications and Safety Considerations
AFco columns are manufactured to meet a variety of technical and safety requirements, ensuring they are suitable for both residential and commercial applications. The following specifications are based on information provided in official documentation and product manuals.
Load-Bearing Capacity
AFco’s structural columns are rated for a maximum load-bearing capacity of 3,000 pounds. This capacity is based on the assumption that the load is evenly distributed over the entire perimeter of the column. The use of load-bearing plates is highly recommended to ensure this distribution is maintained. Columns should not be used to support structures such as second-story balconies unless specifically designed for this purpose.
Hardware and Fasteners
Each AFco column installation includes a set of hardware and fasteners designed for secure attachment. The standard kit includes four 2-1/2-inch Phillips wood screws, four 1-3/4-inch Tapcon screws, and one 3-1/2-inch masonry bit. These fasteners are included to ensure compatibility with a range of installation surfaces, including wood, concrete, and masonry.
For repeated use of the column, replacement screw assemblies and hardware can be purchased separately. This is particularly useful for temporary installations or projects where the column may need to be removed and reinstalled at a later date.
Color Options and Customization
AFco columns are available in two standard colors: gray and red. Additionally, the “Zip” Adjustable Columns are available in safety orange, which is often used in high-visibility applications such as construction zones or temporary supports. Customization options may be available upon request, depending on the specific product line and manufacturing capabilities.
Compliance and Certification
All AFco columns are manufactured in compliance with ICC Accreditation (ESR-2452) and meet all relevant building code standards. This ensures that the columns are suitable for use in a wide range of applications and environments. For projects requiring specific compliance documentation, AFco provides detailed certification and labeling for each product.
Installation of Aluminum Columns
In addition to structural steel columns, AFco offers a range of aluminum columns that are ideal for decorative and semi-structural applications. These columns are available in round fluted, square fluted, and snap-together styles, and can be installed in both indoor and outdoor environments.
1. Measuring and Cutting
The first step in installing an aluminum column is to measure the height of the space where it will be placed. The column should be cut to the appropriate length, ensuring a snug fit within the structural framework. For best results, all column staves should be cut square and to the same length to maintain visual consistency and structural integrity.
2. Assembling and Positioning
Once the column is cut to size, it should be assembled and positioned within the upright base. The top portion or capital is then slid over the column and aligned with the base. A level should be used to ensure the column is plumb and properly aligned.
3. Securing the Column
To secure the column, use the appropriate anchoring fasteners, such as AFCO Column Hold Down Clips or AFCO Hurricane Installation Brackets. These fasteners are designed to provide a secure connection between the column and the floor or ceiling surface. The column should be attached to both the floor and ceiling to distribute the load evenly and prevent lateral movement.
For decorative applications, it is important to use color-matching screws and pre-drill the screw holes to prevent splitting or damage to the material. This ensures a clean and professional finish while maintaining structural integrity.
4. Installing Decorative Elements
AFco offers a range of decorative elements, including capitals, wraps, and skirts, that can be added to aluminum columns for aesthetic enhancement. These elements are typically installed after the structural components are secured.
