Metallic ornamental fences are a popular choice for many homeowners in upscale neighborhoods. Although they are more expensive, ornamental fences are a more attractive option for many homeowners as they are more aesthetically appealing and may add value to a property.
Components
Despite the complexity inherit in the elaborate style of ornamental fences, they may are sometimes surprisingly simple in their structure. The structure consists of post, post caps, rails, pickets, and one or more gates. Posts and rails provide the framework for the fence while the pickets fill the spaces between posts. Posts and sometimes pickets may be topped by caps. Alternatively, the the top rail may also top the pickets and posts. Gates provide pedestrian and vehicular access. These fences may also be combined with decorative walls. To reduce costs, many companies offer styles in pre-fabricated condition. The metal may also be painted in colors that best compliment the rest of the landscaping elements. The possibility of shaping the various components into different shapes and sizes permits a high degree of artistic expression and thus enhance the entire landscape of the residence. Although, larger, heavier, and therefore stronger fence components offer generally greater durability and security, they are more costly and consumers should balance their security requirements and maintenance allowance balanced against the total cost of the fence.
Materials
Most metallic ornamental fences are usually made of steel , but aluminum is also commonly used. There are advantages to each. Steel is sturdier and more durable, however aluminum is more resistant to corrosion. Consumers usually choose from two choices. Welded steel fences feature steel, welded together to form fence sections and then painted. Alternatively, assembled component systems machine-punch galvanized steel and then fasten the parts together with brackets. Aluminum fences are assembled by attaching the sections to punched holes in the posts with screws or rivets or affixing the sections to the posts with brackets. Consumers should also note that welded steel requires the most maintenance due to higher susceptibility to corrosion.
Once, wrought iron was a popular material and many people often refer to a wrought iron fence, however, true wrought iron, forged by a blacksmith, is no longer commonly produced. The production of wrought iron is extremely expensive and labor intensive and is affordable only to the extremely wealthy. Nevertheless, wrought iron does offer some advantages. Its production includes mixing iron silicate into the metal while it is still pliable. The iron silicate enhances the finished product by making it more stress and corrosion-resistant. In addition, the irregular surface of wrought-iron enables it hold coating materials more efficiently than other metals, further augmenting its resistance to corrosion. Finally, it allows even greater originality in the artistic quality of the fence, as opposed to the usage of pre-fabricated details.
As with all fences, the security and durability of metallic ornamental fences depends on the strength of the materials used. The metal must be strong enough to withstand expected stress. A common measurement of the metal's strength is 45,000 pounds per square inch.
