What are the dimensions of expanded metal?

There are three primary dimensions of expanded metal: thickness, width, and length. The thickness of expanded metal is typically measured in Gauge, with a higher number indicating a thinner metal. The width is measured at the widest point of the metal, and the length is measured at the longest point.

The most common size of expanded metal is 4'x8'. This size is typically used for heavier-duty applications, such as security grates or industrial flooring. For lighter-duty applications, such as fencing or screening, smaller sizes such as 2'x4' or 2'x2' are more common.

The thickness of expanded metal is an important factor to consider, as it affects the overall strength and durability of the metal. For applications where the metal will be subject to heavy wear or high levels of stress, a thicker metal is typically used. For lighter-duty applications, a thinner metal can be used.

The width of expanded metal is also an important factor to consider. The width of the metal affects the amount of surface area that is available for gripping or attaching. For applications where a strong grip is needed, such as on stairs or in industrial settings, a wider metal is typically used. For applications where a lighter grip is needed, such as in fencing or screening, a narrower metal can be used.

The length of expanded metal is the final dimension to consider. The length of the metal affects the overall stability of the metal. For applications where the metal will be subject to high levels of stress, such as in security grates or industrial flooring, a longer metal is typically used. For lighter-duty applications, a shorter metal can be used.
