Steel Net

Expanded wire mesh is a variety in the metal screen industry. Also known as metal mesh, diamond mesh, iron mesh, metal expanded mesh, heavy steel mesh, foot mesh, punched aluminum sheet mesh, stainless steel mesh, granary mesh, antenna mesh, filter mesh, audio mesh, etc.
specification
Short Pitch (SWM): The length of a short rhombus diagonal from the center of the node to the center of the node.
Long Pitch (LWM): The length of the long rhombic diagonal from the center of the node to the center of the node.
Short pitch (inner hole) (SWD): the length of the diagonal of the short rhombus hole (as shown)
Long Pitch (Inner Hole) (LWD): The length of the diagonal of the long diamond hole. (Pictured)
Strand: The edge of the diamond mesh hole of the expanded metal (as shown in the figure). The width of the stem is the length of the metal plate used to make a wire stem.
Bond: The junction of two silk stalks.
Thickness: The thickness of the original steel sheet.
Roll: A rolled wire mesh that indicates a specific length and width.
Mesh: A steel mesh that indicates a specific length and width
Weaving and characteristics
It is made of steel sheet through stamping and stretching; it is divided into expanded metal mesh and stainless steel expanded metal mesh; beautiful and elegant, durable.
Surface treatment
PVC dip (plastic spray, plastic coated), hot-dip galvanized, electro-galvanized, anodized (aluminum sheet), spray anti-rust paint, etc
Anti-rust method
First, add some rare elements in ordinary steel to change the internal structure of the metal.
Second, cover the metal surface with a protective layer to isolate the surrounding corrosive medium, thereby preventing the anti-corrosion effect. For example: the surface of the expanded metal is coated with oil, vaseline, paint or covered with non-corrosive non-metallic materials such as enamel, pvc, etc .; the surface of the expanded steel is plated with zinc, chromium, nickel, etc. ; Use chemical methods to form a fine and stable oxide film on the surface of steel. For example, a thin black iron oxide film is formed on the surface of steel parts such as machine parts and guns.
Third, often wipe metal equipment or place desiccants in precision instruments and add a small amount of corrosion inhibitors that can slow down the corrosion rate in corrosive media.
