  2. Sheet metal - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal

    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 ...

  3. Bending (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Bending_(metalworking)

    In bottoming, the sheet is forced against the V opening in the bottom tool. U-shaped openings cannot be used. Space is left between the sheet and the bottom of the V opening. The optimum width of the V opening is 6 T (T stands for material thickness) for sheets about 3 mm thick, up to about 12 T for 12 mm thick sheets.

  4. Birmingham gauge - Wikipedia

    en.wikipedia.org/wiki/Birmingham_gauge

    The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm).

  5. Metal profiles - Wikipedia

    en.wikipedia.org/wiki/Metal_profiles

    Metal profile sheet systems are used to build cost efficient and reliable envelopes of mostly commercial buildings. They have evolved from the single skin metal cladding often associated with agricultural buildings to multi-layer systems for industrial and leisure application. As with most construction components, the ability of the cladding to ...

  6. Corrugated galvanised iron - Wikipedia

    en.wikipedia.org/wiki/Corrugated_galvanised_iron

    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 ...

  7. Hemming and seaming - Wikipedia

    en.wikipedia.org/wiki/Hemming_and_seaming

    hemming process A closed hem A seam. Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Hemming is the process in which the edge is rolled flush to itself, while a seam joins the edges of two materials.

  8. Shop drawing - Wikipedia

    en.wikipedia.org/wiki/Shop_drawing

    Leite et al. [3] compared types of clashes identified in a manual coordination process (overlay of 2D drawings on a light table by pairs of subcontractors) and through automatic clash detection using a Building Information Model (BIM). The automatic clash detection identified several clashes that were missed by the subcontractors, who were ...

  9. Mill scale - Wikipedia

    en.wikipedia.org/wiki/Mill_scale

    Mill scale is a complex oxide that contains around 70% iron with traces of nonferrous metals and alkaline compounds. Reduced iron powder may be obtained by conversion of mill scale into a single highest oxide i.e. hematite (Fe 2 O 3) followed by reduction with hydrogen.
