Expanded Metal Fence

Expanded Metal Fence

An expanded metal fence may be produced from metals such as stainless steel alloys, aluminum, steel, titanium and many other ferrous or non-ferrous metals including iron alloys such as copper and brass. Each of these expanded metals has different physical properties that are enhanced by the expansion process. Stainless steel expanded metal is virtually weather proof because of the chromium oxide in its chemical structure, which resists rust and is self-repairing and therefore an obvious option for expanded metal fencing. Expanded aluminum is a popular fencing choice when aluminum alloys are used, because the alloys produce a lightweight but sturdy metal that strengthens in the cold, while being aesthetically pleasing and cost effective. Titanium expanded metal has aluminum's impressive strength to weight ratio as well as stainless steel's extreme resistance to corrosive materials, which makes it another popular choice for expanded metal fencing. However, titanium is a more difficult raw material to extract from the earth, which means it is also more expensive. The strengths and weaknesses of a metal being considered for expanded fencing must be carefully considered before purchase.  

Depending on use and aesthetics, the cutout pattern of the expanded metal sheets used to produce the expanded metal fences may be varied from a traditional diamond shaped pattern to nearly any other shape or pattern imaginable. Flame like patterns, circles and four-leaf clover patterns are all common options as well. However, the diamond pattern, which in and of itself may be altered through stretching or condensing its shape, is a simple and popular option that is often chosen. In general, expanded metal fences are popular for school ground fencing and home fencing because they have no perforated edges or dangerous points at the top. They are one of the most kid-friendly fencing options on the market today that still provides significant strength and durability. Also, because of its high strength and shielding properties, expanded metal fences are often used in high security applications such as railroad right-of-ways, international borders, high-voltage enclosures and detention centers. The stretched out sheets of expanded metal used for fencing are seamless and easily weld together, without seams or joints that will wear and break over time.
