Expanded metal mesh material are carbon steel plate, stainless steel, galvanized steel, aluminum, aluminum foil, lead, nickel plate, titanium, aluminum-magnesium alloy panels. Conventional mesh is formed in a diamond pattern. It has other pattern of hexagonal, round, triangle, scale-like opening.

The term of expanded metal mesh:
SWD (Short Way of the Diamond) is the distance from the middle of the bond on one side to the middle of the bond on the opposite side.
LWD (Long Way of the Diamond) is the distance across the largest dimension of the diamond measured halfway between the diamonds.
SWO (Short Way of the Opening) is the width of the opening of the shortest side of the diamond. SWO does not include the strand width, where SWD (Short Way of the Diamond) does.
LWO (Long Way of the Opening) is the length of the opening of the longest side of the diamond. LWO does not include the strand width, where LWD (Long Way of the Diamond) does.
Strand and Bond Expanded metal is composed of strands and bonds. Strands form the sides of the expanded metal openings. Bonds are where the strands intersect. In other words, the bond is where each diamond shaped opening is connected with the next opening.
Thickness is the measurement from the top surface to bottom surface of the expanded metal piece.
Expanded metal Roll: that the specific length and width of the wound into the roll of steel mesh.
Expanded metal sheet: The expanded metal that show specific length and width.
