Polyvinyl chloride is formed in flat sheets in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost (see closed-cell PVC foamboard). Sheets are cut using saws and rotary cutting equipment.
PVC foamboard is distinct from the extra-lightweight foamcore board, laminated of foam and card surfaces, used for indoor signage and modelling. Like PVC, closed-cell PVC foamboard is solid and has a very rigid structure. Where it differs is in its closed-cell foam structure, which makes it very light (as little as half the weight of solid PVC ...

Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...
Vinyl floor tiling. Vinyl composition tile (VCT) is a finished flooring material used primarily in commercial and institutional applications. Modern vinyl floor tiles and sheet flooring and versions of those products sold since the early 1980s are composed of colored polyvinyl chloride (PVC) chips formed into solid sheets of varying thicknesses (1 ⁄ 8 in or 3.2 mm is most common) by heat and ...
However, in the actual press-working, the deep-drawability of steel sheets cannot be determined only by the value of and the measure of planar anisotropy, is more appropriate. In an ordinary cold rolled steel, R 90 {\displaystyle R_{90}} is the highest, and R 45 {\displaystyle R_{45}} is the lowest.

In 1957, Friden purchased the Commercial Controls Corporation of Rochester, New York.This gave them the Flexowriter teleprinter, an electric typewriter capable of being used as part of unit record equipment developed in World War II for the Department of the Navy to automatically type "regret to inform you" letters to the survivors of fallen servicemen ...
Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...
