Characteristics Expanded metal sheet

One of the benefits from the manufacturing of expanded metal is that the sheet retains its structural integrity because it has not undergone the stress of having shapes punched in it (like perforated sheet), and the mesh-like pattern will not unravel (like woven mesh can do). Expanded metal has been stretched rather than punched, reducing scrap metal waste; making it cost-effective. The main considerations when using expanded metal will be the chosen thickness and strand dimensions (weight and structural design requirements). Expanded metal can be almost transparent (depending on the opening); it has mechanical properties and is an excellent conductor.
Perforated metal sheet
Perforated metal sheet comes in a virtually endless variety of sizes, gauges, hole shapes and material types. Hole diameters range from a few thousandths of an inch to more than 3 inches, punched in material as thin as foil or as thick as 1-inch steel plate. From lightweight decorative elements to load-bearing structural components, perforated metal offers unique opportunities to combine strength, functionality and beauty.
Wire mesh (welded)
The chance of improper bending of bars is reduced since bending machines bend the mat as a single unit. This provides the exact size of reinforcement where needed through variable bar size and spacing, thereby reduces steel waste. There can be a considerate savings because mesh is easy to handle and can be installed much faster. Typically you can purchase a welded mesh for less than a woven mesh.
Wire mesh (woven)
Wire mesh is adaptable to almost any application. It is extremely durable and very easily cleaned.
