Construction Decorative Expanded Metal Wire Mesh Solid Sheets Fine Workmanship

Construction Expanded metal mesh with fine workmanship for decoration

Expanded Metal mesh are made from solid sheets or coil. A machine then pierces and stretches the sheet into an open diamond pattern.

Expanded metal mesh come in two common types: raised and flattened. Raised sheets have wavy ridges throughout, whereas flattened sheet are truly flat.

Expanded metal mesh is commonly used to guard entry to an area or object or as a barrier, but still allow the free passing of liquids and gases. It can be purchased online and at any Metal Supermarkets location. It can be cut to your exact specifications.

Expanded metal is truly a versatile product. Ferrous and non-ferrous metal sheet can be expanded into a wide range of mesh styles. There are standard expanded metal styles and numerous variations in strand width and opening sizes can be produced to create whatever architectural or industrial pattern is required. Expanded metal is also produced in a flattened form which is created by rolling standard or raised expanded metal.

In bond shearing, the shear line falls through the bonds. The result is an edge configuration of all closed diamonds. For bond shearing the resultant dimensions must be in a multiple of the full diamond dimensions.

In random shearing, the shear line falls at random points on the mesh pattern. Edges are open and diamonds are not matched. Random shearing is necessary when the required overall dimensions are not a multiple of the full diamond dimensions.

SWD - Nominal dimension, Short Way of Design

LWD - Nominal dimension, Long Way of Design

When referring to a sheet size the SWD is always referred to before the LWD. For example a 4x8 sheet means 4 foot dimension is in the SWD direction and 8 foot dimension is in the LWD direction.

SWO - Short Way of Opening

LWO - Long Way of Opening

STRAND THICKNESS - Gauge thickness of the base metal

STRAND WIDTH - Amount of metal fed under dies to produce one strand.

EDGE CONFIGURATION - Condition of the edge of an expanded metal sheet. Usually refers to “open” (random) or “closed” (bond) diamond edges produced from shearing.

EXPANDING - An expanding press simultaneously slits and stretches base material to form a diamond pattern.

LEVELLING - Expanded metal is usually levelled after the expansion process by a levelling roller.

RAISED (abbreviated R) - Expanded metal as it comes from the press. The strands and bonds are set at a uniform angle to the plane of the sheet. This gives added strength and rigidity, as well as a skidding resistant surface.

FLATTENED (abbreviated F) - Expanded metal that has been cold-rolled after expansion, to provide a smooth, flat and level sheet. The flattening process reduces the original gauge of the the base metal and the strand width increases slightly. Some of the heavier expanded metals can not be flattened.

SHEARING - Cutting expanded metal to size to produce various sheet sizes. May be “bond” or “random” sheared.

Expanded metal is often referred to as diamond punched, stretched metal or security mesh. Due to its method of manufacture, expanded metal is one of the most economical steel mesh, or grating material, on the market.

The strength of expanded metal runs along the long dimension, not the short dimension. Sheets of expanded generally come in 4’ short dimension and 8’ long dimension. The long dimension is approximately double that of the short dimension. Expanded metal open area percentage typically falls between 60% to 80%.
