Most property owners are on the look for methods of saving money while enjoying the best look for their property. They will thus opt for prefabricated fencing panels as they assume they can get their fence’s desired color and design at half the cost of fabricating one.

While this might have been so in times past, you can nowadays get a custom fabrication for your fence without going into debt thanks to the technologies available. This makes a custom-made wrought iron fence the best choice for Beverly Hills properties aiming to stand out and exude an air of opulence.

Even seemingly complicated designs will be incorporated into this fence material using forging. This is a process that involves the shaping of your fence through various techniques to achieve a desired geometric shape and boost the strength and fatigue resistance of the material.

Here are the forging methods used for wrought iron.

Drop Forging

This technique encompasses the dropping of a hammer onto your metal to mold it into a die shape. This die denotes the surfaces that will be in contact with the hammer. It is generally a flat shape that will have distinctive surface designs for customization.

Open Die Forging

Open-die forging results in continuous grain flow and more elegant grain size in your patterns with a reduced chance of holes and errors in your fence. Moreover, it results in optimal fence strength and fatigue resistance.

Closed Die Forging

This is also called impression-die forging. The material for your fence will be placed in a die with an attached anvil. When the hammer is dropped on the metal, it causes it to flow and fill the die’s cavities.

Excess metal will be passed from the die cavities generating a flash that cools faster compared with the other material. This forging technique will produce fence sections of up to 25 tons and near exclusive designs that only need a small finishing detail.

Roll Forging

This comprises two semi-cylindrical or cylindrical rolls that will deform a flat bar or round stock. The technique will reduce the thickness of the fencing metal while increasing its length when the material is rolled through the machine.

The machine also has several shaped groves that will progressively shape the metal as it is passed through the machine. Roll forging generates an ideal grain structure in your fence and reduces the metal’s cross-sectional area. It also creates tapered design ends and has little material waste.

The forging techniques mentioned above enable your wrought iron fencing manufacturer to generate any pattern you may be having in mind for your fence. The ideal pattern choice for your fencing will depend on the level of security you are aiming for.

If for instance, you want the highest security level, you can choose patterns that are very close and can thus not enable an intruder. To further enhance the privacy your fence offers, you can include plants alongside it.
