Introduction
Expanded metal mesh refers to: after the metal sheet is processed by special machinery (expanded mesh punching and shearing machine), it is formed into a meshed object.

Material
Low carbon steel plate, stainless steel plate, aluminum plate, copper plate, nickel plate, aluminum-magnesium alloy plate and other metal plates.

Specification
Short Pitch (SWM): The length of a short diamond diagonal from the node center to the node center.

Long Pitch (LWM): The length of the long diagonal of the rhombus 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 diamond-shaped hole (pictured)

Long Pitch (Internal Bore) (LWD): The length of the diagonal of a long diamond-shaped hole. (pictured)

Strand: The side of the diamond-shaped hole of the steel mesh (as shown in the figure), the width of the stem is the length of the metal plate used to make a wire stem.

Node (Bond): The junction of two silk stems.

Thickness: The thickness of the original sheet steel.

Coil: Indicates a specific length and width of expanded metal mesh wound into a coil.

Mesh: Indicates the specific length and width of the expanded metal

Weave and Features
It is made of steel plate by stamping and stretching; it is divided into expanded metal mesh and stainless steel expanded metal mesh; it is beautiful and durable.

surface treatment
PVC dipping (plastic spraying, plastic coating), hot-dip galvanizing, electro-galvanizing, anodizing (aluminum plate), spraying anti-rust paint, etc.

Rust prevention method

1. Adding some rare elements and other ingredients to ordinary steel changes the internal structure of the metal.

2. Cover the metal surface with a protective layer to isolate the surrounding corrosive medium, so as to prevent the anti-corrosion effect. For example: apply engine oil, vaseline, paint or cover enamel, PVC and other corrosion-resistant non-metallic materials on the surface of the expanded metal; use electroplating, hot-dip plating, spray plating and other methods to coat the surface of the steel plate with a layer of zinc, chromium, nickel, etc. ; Use chemical methods to form a fine and stable oxide film on the steel surface. For example, a fine black ferric oxide film is formed on the surface of steel parts such as machine parts and guns.

3. Frequently wipe metal equipment or place desiccant in precision instruments and add a small amount of corrosion inhibitor that can slow down the corrosion rate in the corrosive medium.

type
Classification by material: low carbon steel sheet, aluminum plate, stainless steel plate, aluminum magnesium alloy plate, steel plate and other plates.
