    15. BCN 5618 15 Metal Joists (open web steel joists) Metal joists are prefabricated lightweight trusses that are available in different series: J and K series- spans to 56’ (short span) LJ and LH series – spans to 96’ (long-span) DLJ and DLH series – spans to 144’ (deep long-span) Designation: 12K4 12 = depth in inches K = joist series 4 = designation within series (the higher the number, the heavier the joist)

    30. BCN 5618 30 Type of Decking Floor: simple with electrical raceways acoustical finishes recessed lighting Roof: simple can receive recessed lighting has acoustical properties

    31. BCN 5618 31 Steel Deck Units

    32. BCN 5618 32 Finish, thickness and gage Finish: unpainted primed painted galvanized Thickness: 1.5” (most common) 3”, 4.5”, 6”, and 7.5” Gage: 22, 20, 18, 16, and 14

    33. BCN 5618 33 Cold Formed Metal Framing Cold-formed steel is created by bending thin material such as steel sheet or plate into the desired shape without heating.

    34. BCN 5618 34 Cold-formed steel

    35. BCN 5618 35 Metal Studs Light gage (25 to 20 for non-load bearing and 18 to 12 for load bearing) cold-formed steel. Electrogalvanized to resist corrosion. Available in thicknesses of 1 5/8 , 2 ½ , 3 ½ , 4, and 6 inches. Unit: LF, note type, gage, and width
