While expanded metal may present a virtually impenetrable barrier to intruders, which has been mostly used for security fencing. They are basically manufactured in two types - raised and flattened.įor the openings of expanded metal permit light, sound, air, heat and liquid to pass through, it is widely used for facade cladding, display screening, ceilings, furniture, etc. Compared with perforated metals and woven wire products, expanded metal has many advantages including cost effective and rigidity, for it is slit rather than punched and it won't ravel, if cut at one end, the remaining strands continue to hold.Įxpanded metal products are produced from carbon steel, galvanized steel, stainless steel, as well as aluminum, copper and a variety of alloys of nickel, titanium and other metals. Expanded metal has greater strength to weight ratio than solid sheet steel, and it is an economical, greener engineered alternative because there is no material in production. Niles Expanded Metals offers multiple options for protective layering including, but not. Protective layering is a critical factor to consider for corrosion resistance, hardening and protection of base materials. In the expanding process, a solid sheet or roll is simultaneously cut and stretched into a non-raveled unit with uniform-sized openings. Our expanded metal meshes are available in base metals of aluminum, carbon steel, titanium, silver, copper, brass, nickel, mild steel and zinc as well as alloys of stainless steel. Although there are standard designs, what makes our process so versatile is the pattern variations. It is available in a wide variety of ferrous and non-ferrous metals, as well as a wide range of mesh sizes. Expanded metal is an extremely versatile material. It includes all metallic elements or alloys that have undergone a specific machining process, providing an open grid pattern on the surface. Metalex has the widest range of expanded metal products in the industry. Expanded metal is an extraordinarily versatile product that benefits our lives.
