Chain link fence posts come in various standard sizes, which are typically determined by the height and purpose of the fence. The main types of posts used in chain link fencing are terminal posts, line posts, and top rails, each serving a specific function. 1. **Terminal Posts**: These are the corner, end, and gate posts that provide structural support. Standard sizes for terminal posts range from 2 1/2 inches to 4 inches in diameter. The height of terminal posts is usually 2 feet longer than the height of the fence fabric to allow for proper installation in the ground. 2. **Line Posts**: These are the intermediate posts placed between terminal posts to support the chain link fabric. Standard sizes for line posts range from 1 5/8 inches to 2 3/8 inches in diameter. The height of line posts is typically 1 foot longer than the height of the fence fabric. 3. **Top Rails**: These are horizontal bars that run along the top of the fence, connecting the terminal and line posts. Standard sizes for top rails are usually 1 3/8 inches to 1 5/8 inches in diameter. The choice of post size can also depend on the gauge of the chain link fabric, the wind load, and the specific application, such as residential, commercial, or industrial use. For example, heavier gauge fabric or higher fences may require larger diameter posts for added strength and stability. Additionally, local building codes and regulations may influence the required sizes for chain link fence posts.

These tools will help ensure a successful and efficient installation of a chain link fence.

To attach chain link fabric to posts, follow these steps: 1. **Prepare Materials**: Gather chain link fabric, tension bars, tension bands, carriage bolts, nuts, and tie wires. Ensure you have a post hole digger, pliers, and a wrench. 2. **Install Terminal Posts**: Set terminal posts (end, corner, and gate posts) in concrete, ensuring they are plumb and aligned. Allow concrete to cure. 3. **Attach Tension Bands**: Slide tension bands onto each terminal post before the concrete sets. Space them evenly, with the flat side facing outward. 4. **Insert Tension Bar**: Unroll the chain link fabric and weave a tension bar through the first row of links. This bar will provide stability and a point of attachment. 5. **Connect Fabric to Terminal Post**: Position the tension bar against the terminal post. Secure it using the tension bands and carriage bolts. Tighten nuts with a wrench. 6. **Stretch the Fabric**: Use a come-along or fence puller to stretch the fabric taut along the line posts. Ensure the fabric is level and free of sagging. 7. **Attach to Line Posts**: Secure the fabric to line posts using tie wires. Wrap the wire around the post and through the fabric, twisting it tightly with pliers. 8. **Secure Bottom and Top**: Use additional tie wires to attach the top and bottom of the fabric to the tension wire or rail, ensuring the fence is stable. 9. **Trim Excess Fabric**: Cut any excess fabric with bolt cutters, ensuring a clean edge. 10. **Final Adjustments**: Check for tension and alignment. Make any necessary adjustments to ensure the fence is secure and aesthetically pleasing.

The cost of installing a chain link fence per foot typically ranges from $8 to $18. This price can vary based on several factors, including the height and gauge of the fence, the type of coating (galvanized or vinyl), local labor rates, and any additional features such as privacy slats or gates.

To maintain and repair a chain link fence, follow these steps: 1. **Regular Inspection**: Periodically check the fence for damage, rust, or loose fittings. Look for bent or broken links, sagging sections, and damaged posts. 2. **Cleaning**: Remove dirt, debris, and vegetation around the fence. Use a garden hose or pressure washer to clean the fence, removing any accumulated grime or rust. 3. **Rust Prevention**: Apply a rust-inhibiting primer and paint to any rusted areas.

Adjust or replace sagging gates by tightening hinges or installing an anti-sag kit. 8. **Vegetation Control**: Trim plants and trees near the fence to prevent damage and reduce moisture buildup, which can lead to rust. Regular maintenance and prompt repairs will extend the life of your chain link fence, keeping it functional and aesthetically pleasing.

Galvanized chain link fences are made from steel wire that has been coated with a layer of zinc to prevent rust and corrosion. This process, known as galvanization, enhances the durability and longevity of the fence, making it suitable for various weather conditions. Galvanized fences are typically silver in color and are valued for their strength and cost-effectiveness. They are commonly used in industrial, commercial, and residential settings where functionality is prioritized over aesthetics. Vinyl-coated chain link fences, on the other hand, involve an additional layer of vinyl or PVC coating over the galvanized steel wire. This coating provides an extra level of protection against rust and corrosion, further extending the fence's lifespan. The vinyl coating is available in various colors, such as black, green, or brown, allowing for better aesthetic integration with the surrounding environment. This makes vinyl-coated fences a popular choice for residential areas, parks, and recreational facilities where appearance is important. In terms of maintenance, both types require minimal upkeep, but vinyl-coated fences may require occasional cleaning to maintain their appearance. The vinyl coating also provides a smoother surface, reducing the risk of injury from sharp edges, which can be a consideration for areas frequented by children or pets. Cost-wise, galvanized fences are generally less expensive than vinyl-coated ones due to the additional materials and processing involved in the latter. However, the choice between the two often depends on the specific needs and preferences regarding durability, appearance, and budget.
