Shop / Spec Sheets

Direct Metals® is an expanded metal supplier of versatile and economical expanded metal that is made from a high-quality metal sheet. Our expanded metal sheet is available in many sizes, openings, and material types, making us the best place to buy expanded metal. Direct Metals® offers expanded metal materials such as aluminum expanded metal, carbon steel expanded metal, galvanized steel expanded metal or stainless steel expanded metal. Expanded metal is a metal sheet that is uniformly slit and stretched, forming diamond-shaped openings in the sheet that allow for light, air, heat, and sound passage. The strands and bonds of the diamonds in the sheet add strength and rigidity. Since no metal is lost in the expanding process, expanded metal is a cost-effective alternative to perforated metal.

Expanded Metal FAQs

Q: What types of materials are made into expanded metal sheet?

A: There are many types of materials that can be made into expanded metal sheet. Aluminum expanded metal, carbon steel, galvanized steel, nickel, silver, copper, and stainless expanded metal sheets are available.


Q: Why is the percentage of open area important for expanded metal sheet?

A: The percentage of open area determines the amount of space available for the passage of air, water, and light through the expanded metal sheet. This information is important for engineers to know based on the end application for which the sheet is used.


Q: What are common applications for expanded metal?

A: Expanded metal is extremely diverse. One example of a common application is security mesh for the protection of industrial machinery and electrical equipment, or unwanted access to restricted areas. Some other applications for this include railing mesh, fences, vents, and shelves. Heavy carbon steel expanded metal can be used as stair treads for oil tanks, working platforms, corridors and walkways. It is also used in the construction of roads, bridges, railways, ramps, and steel flooring.


Q: Why is expanded metal commonly used?

A: The many small openings in the expanded metal material allow flow through of air, water, and light, while still providing a mechanical barrier to larger objects. Another advantage to using expanded metal as opposed to plain sheet metal is that the exposed edges of the expanded metal provide more traction, which has led to its use in catwalks or drainage covers.


Q: What do SWD and LWD mean in reference to expanded metal sheet?

A: SWD stands for Short Way of the Diamond and LWD stands for Long Way of the Diamond. These acronyms are used when ordering expanded metal sheet.
