Expanded Metals Types and Terms
Types of Expanded Metals
- comes with a variety of
mesh patterns other than the standard diamond shape, and may also be
produced using more decorative metals, such as copper or silver.
- is used for walkways and platforms designed for pedestrian
foot traffic.
- is fencing produced from expanded
metal. It offers strength, safety, durability and aesthetic qualities
not found with many other types of fencing.
- is
used when smaller openings are desired, such as in filters.
- can be found in a number of strengths for applications varying
from walkways and fencing to corner netting for use under plaster
and drywall.
- has been cold-rolled after
expansion, providing a smooth, flat and level sheet. The metal's
thickness thus will be reduced by up to ten percent.
- has very small opening in comparison to other types of expanded
metals or mesh.
- comes directly
from the press and has a raised pattern. The strands and bonds are
set at a uniform angle to the plane of the sheet.
Expanded Metal Terms
- Custom
size expanded metal part made to customer's specifications.
- The
solid intersection of two strands of metal found in expanded metal.
- Manufactured
closed perimeter diamond.
- Expanded
metal produced as one continuous coil of the material rather than in
individual pieces.
- This is the description
of the open area formed by strands and bonds. Normally the open area
is diamond shaped.
- All expanded metal products except
grating are leveled after having been expanded.
- Long way of diamond or long way of opening is the dimension measured
across the sheet in a direction parallel to the largest dimension of
the diamond.
- This is the nominal distance from the
mid-point of one bond to the mid-point of the next bond measured across
the SWD. Mesh is expressed in inches.
- The
total open area of a section of expanded metal. Found by calculating
two times the strand width, divided by the short way of diamond (SWD),
and then taking the inverse of the resulting number.
- Short way of diamond or short way of opening is the dimension
measured across the sheet in a direction parallel to the smallest dimension
of the diamond.
- Thickness
of base metal when in the unflattened state.
- The
dimension associated with the thickness of one strand of metal.
