Expanded Metal
Overview
Qinghe Expanded Metal is formed in an expanding press. The basic metal is concurrently slit and cold-formed, which expands the slits into square, diamond, hexagonal, decorative shaped. Expanded metal is a form of metal stock made by shearing a metal plate in a press, so that the metal stretches, leaving diamond-shaped voids surrounded by interlinked bars of the metal. The most common method of manufacture is to simultaneously slit and stretch the material with one motion.
Terms：
SWD: The distance from a point on a bond to a corresponding point on the following bond measured across the Short Way of Design. This distance is also sometimes referred as “pitch SWD”.
LWD: The distance from a point on a bond to a corresponding point on the following bond measured across the Long Way of Design. This distance is also sometimes referred as “pitch LWD”.
SWO: Short Way of Opening, the distance measured from the inside of the bond across to the inside of the bond SWD.
LWO: Long Way of Opening, the distance measured from the inside of the bond across to the inside of the bond LWD.
Bond: The intersection of two strands and it is always the width of two strands.
Strand Thickness: Gauge thickness of sheet metal material of expanded metal.
Strand Width: Amount of metal fed under dies to produce the expanded metal strand.
Material:
Carbon steel expanded metal materials
Hot-rolled carbon steel, Cold-rolled carbon steel
Stainless steel expanded metal materials
AISI302, AISI304, AISI304L, AISI304H, AISI310, AISI316 and AISI316L, AISI430
Aluminum Expanded Metal materials
Aluminum 1060, 3003, 5050,1100, 1145, 1070, 5052, 6061-T6, 7075, 8011.
Applications:
Expanded Metal has thousands of applications for enclosure, protection, support, decoration and filtration, including grills, fencing, walkways, furniture, etc.
Hole Types of expanded metal:
Micro Hole Expanded Metal
Precision Expanded Mesh
Decorative Expanded Metal
Flattened & Un- Flattened
Un-flattened Expanded Metal: Expanded metal mesh as it comes off the machine. The strands and bonds are set at a uniform angle to the plane of the sheet. This adds strength and rigidity, allows air circulation, distributes the load on the metal to the supporting frames as well as making a skid resistant surface.
Flattened Expanded Metal: Manufactured by passing the standard expanded metal mesh sheet through a cold roll reducing mill parallel to the LWD. By flattening the sheet, the bonds and strands are turned down to produce a smooth and flat surface, reducing the overall thickness and extended the diamond pattern (LWD). Cross roll flattening is done by passing the expanded metal sheet through a cold roll reducing mill parallel to the SWD. The result is the same except the diamond pattern SWD is extended.
Width:
1000MM, 1220MM, 1250MM, 1500MM. The measurement of the shortest side of the sheet or cut-to-size expanded metal piece. The max size is bounded by the thickness. In generally speaking, more than 3MM thickness expanded metal, the max size is 10 feet
Length:
The measurement of the longest side of the expanded metal sheet or cut-to-size piece. In rolls, the Max length is 100 feet
Thickness:
From 0.3MM to 15MM
Hole size:
Min: SWM X LWM ： 1MM X 2MM
Max: SWM X LWM ： 200MM X 400MM
