What is Expanded metal?
Expanded Metal Fabrication are produced from solid sheets or plates
of carbon,galvanized and stailness steel,as well as aluminum and a
veriety of alloys of copper,nickel,silver,titanium and other
Raised expanded metal
Expanded metal as it comes off the machine.The strand and knuckles
are set at a uniform angle to the plane of the sheet.This adds
strength and rigidity,allows air circulations,and distributes the
load on the metal to the supporting frame.
Flattened expanded metal
Manufactured by passing the raised expanded sheet through a cold
roll reducing mill.By flattening the sheet,the knuckles and strands
are turned down to produce a smooth and flat surface,reducing the
overall thickness and elongation the diamond pattern(LWM).
When ordering expanded metals,give complete profile specifications
to avoid possible error:
- mesh reference
- quantity of sheet
- sheet size(LW Dimensions first see diagram)
- types of material,e.g.steel,aluminum,etc
- finish,e.g,untreated or galvanized
- tolerance(if required)
- where applicable specify raised or flat
