- Different regulations are imposed on chain-link fences in different areas, setting restrictions on both the height and width of a fence based either on where the fence is going or what it is being used for. Oftentimes fence installation is also specified, with fence posts needing to be installed in the ground at a specific depth to pass regulations in the area the fence is being installed in. The width of the hole will depend on the width of the fence post.
- Two common types of chain-link fences are galvanized and vinyl-coated. Galvanized fences are silver in color with the links in the fence made up of standard metal. Vinyl-coated fences have a thin layer of vinyl over the exposed pieces of metal. This vinyl also allows homeowners to select varying fence colors to meet their needs.
- Chain-link fences are held together by posts that are dug into the ground at the corner points, or "joints," of the fence. The actual chain-link part of the fence is then stretched between two corner posts or between the corner post and a gate. A length of fence will be intermittently interrupted by posts. The standard size for the posts of a residential chain-link fence are six inches in diameter and 30 inches plus the desired height of the fence. The 30 inches accounts for the part of the post that is inserted below ground.
- Once the posts for a chain-link fence are installed in the ground, they typically must be reinforced with a material like concrete to both make sure the fence is sturdy and comply with local building codes and regulations. This concrete ensures the fence is as sturdy as possible and that a post itself won't bring the fence down if someone applies pressure or weight to it.
