Expanded metal grating is often used for flooring, shelving, security screens, and barriers. It is also a very affordable material used in industrial, architectural, and commercial settings.

Stainless steel expanded metal and grating products are available from Huijinmaterials. It is often difficult for customers to determine what measurements to provide when selecting the right mesh pattern for their application. Here is a guide to measuring and specifying expanded metal...
 

What Are the Types of Expanded Metal?

 
Common types of expanded metal include: 
 

This is the most basic and common type of expanded metal.It is produced by slitting and stretching a sheet of metal, creating diamond-shaped openings.Standard expanded metal is available in various materials such as steel, aluminum, stainless steel, and others.

2.Flattened Expanded Metal

After the standard expanded metal is created, it can be further processed through a flattening process, which reduces the thickness of the material and creates a smoother surface.Flattened expanded metal is often used when a flat and smooth surface is desired.

3.Raised Expanded Metal

In contrast to flattened expanded metal, raised expanded metal has raised ridges on the surface.The raised pattern provides enhanced strength and rigidity, making it suitable for certain applications where structural support is important.

4.Micro Mesh Expanded Metal

Micro mesh expanded metal has very small openings, making it suitable for applications where fine filtration or screening is required.It is commonly used in air filtration systems and other applications that demand a high level of precision.

5.Architectural Expanded Metal

Architectural expanded metal features a diamond design with distinct aesthetic elements. For a terrific mix of style and function, go with architectural expanded metal.  
 

Expanded Metal Sheet Dimension Introduction

 
expanded metal sheet dimension introduction
 
LWM: The distance from a point on a knuckle to a joint point on the following knuckle mesured across the long way.
SWM: The distance from a point on knuckle to a joint point on the following knuckle measure across the short way.
LWO: Long way of opening, the distance measured from the inside of the knuckle across to the inside of the knuckle LWO.
SWO: Short way of opening, the distance measured from the knuckle across to the inside of the knuckle SWO.
KNUCKLE: The intersection of two strands and it is always the width of two strands.
OVERAL THICKNESS: The actural measurement of the thickness of the mesh measured at the knuckle.
OPEN AREA: The percentage of open area is showing on the mesh.
STAG ENDS: Incomplete strands existing beyond the joints of mesh either LWD, SWD or both.
MATERIAL: The material is available in carbon steel, galvanized sheet, stainless steel, aluminum etc.
