Simply establishing the area to be considered becomes a point of discussion. select an abbreviation to learn more. SHEARING. Terminology of Expanded Metal. Expanded Metal Ordering Procedure. Made from a sheet of metal uniformly slit and stretched, forming diamond-shaped openings in the sheet – expanded metal is a one piece construction, diamond-shaped trusses add strength and rigidity. Also called regular, unflattened, or raised expanded metal. Strand width Metal plate length for making one strand. mesh pattern in a single operation. EXPANDED METAL TERMINOLOGY BOND: WHERE TWO STRANDS INTERSECT SWD SWO LWO LWD Strand Thickness LWD SWD S.W.D. Conventional mesh is formed in a diamond pattern. Use them to create safety guards for equipment and machinery.. Steel is lightly oiled. The first number designates nominal diamond pitch Short Way of Diamond (SWD) The second number used in conjunction with the first may specify the gauge of metal. Long way of diamond (LWD) Expanded Metals Terminology: Expanded Metal: A rigid piece of metal that has been slit and drawn into an open mesh pattern in a single operation. This is closely controlled and is directly related to the weight, overall Publish Time:2015-08-21 Hits:1048. Hole Center . Hole center is one of two measures of perforation spacing. L.W.O. Expanded Metal: A rigid piece of metal that has been slit and drawn into an open mesh pattern in a single operation. Our expanded metals are often used as Safety Grating, Chimney Cpas, Wire Mesh, guards, fixtures, filters and more. S.W.O. National Hardware N301-606 4075BC Expanded Steel - 3/4" … It is stronger, lighter in weight and more rigid than the original base metal. There is an instruction of ordering expanded metal panels, it helps you make an order. (See Diagram), LWD: Long way of design measured from center of bond to center of bond. BB/S, an older term not much used, expanded metal mesh or walkway grating that is sheared or cut to a defined size along a centerline on the bond or knuckle. Measured from the centre of one bond to the centre of the next. Terminology. Raised panels have strands that overlap to provide a skid-resistant surface. The strands and bonds are set at a uniform angle to the plane of the sheet. Expanded metal as it comes from the press. Terminology. SWD Nominal dimension, Short Way of Diamond.
