Galvanized Architectural Metal Mesh , Expanded Mesh Screen SGS Certification for facade building

Galvanized or Aluminum or Stainless Steel Expanded Metal Mesh Sheet

• Expanded mesh Can be stamped into a variety of products with a variety of metal sheets.
• All products are produced and processed by advanced computer technology.
• The hole types are diverse and the arrangement is flexible.
• In the years of production practice, which can cut, bend and edging the products.
• Deep processing such as surface treatment.
• The expanded mesh has the characteristics of uniform mesh, flat mesh surface, high friction coefficient and high strength.
• It can produce steel mesh products with th ickness of 0.5-3mm. it are also cut and processed to manufacture workpieces.

1. material:expanded wire mesh usually made of stainless steel plate,copper plate,galvanized plate,
aluminum plate,alloy plate,iron or other material,we can custom according your request.

2. hole shape:diamond,hexagon or other shape

3. surface treatment:hot-galvanized,cold-galvanized,pvc coated,electro-galvanized,spray anti-rust paint and
so on

4. features:the surface of expanded wire mesh is smooth and flat,the appearance is beautiful,the surface
treatment made it anti-rust and anti-acid and anti-alkali .the copper material made it's colour more beautiful.

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%.

This product is ideal for security, decoration or traction applications.

Short pitch (SWM): The length of the short diamond diagonal from the center of the node to the center of the node.
Long pitch (LWM): The length of the long diamond diagonal from the center of the node to the center of the node.
Short pitch (inner hole) (SWD): the length of the diagonal of a short diamond hole
Long pitch (inner hole) (LWD): the length of the diagonal of a long diamond hole

Straw: The width of the side stalk of the diamond-shaped hole of the stencil is the length of the metal plate used to make a stalk.
Bond: The junction of two silk stems.
Thickness: The thickness of the original sheet steel.
