    15. BCN3611 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)

    16. BCN3611 16 Open web steel joist

    17. BCN3611 17 Pitched Top Chord Joists

    18. BCN3611 18 Span Length

    19. BCN3611 19 Joist Girders Designed to carry the regularly spaced, concentrated loads consisting of the end supports of joists. Designation: 48G 8N 8.8K 48G = depth in inches 8N = number of joist spaces 8.8K = load on each panel point in kips

    20. BCN3611 20 Joist Girder

    21. BCN3611 21 Quantity takeoff Determine the LF of each different type of joist, use manufacturer’s table to find the weight per ft and total weight. Note type and number of accessories: bridging (diagonal or horizontal) end anchorage (beam or wall)

    22. BCN3611 22 Horizontal Bridging

    23. BCN3611 23 Diagonal Bridging

    28. BCN3611 28 Metal Decking Metal decking is used for floor and roof applications. Determine type of decking, thickness, gage of metal, finish required, and method of attachment Unit: square (100 sf)

    29. BCN3611 29

    30. BCN3611 30 Type of Decking Floor: simple with electrical raceways acoustical finishes recessed lighting Roof: simple can receive recessed lighting has acoustical properties

    31. BCN3611 31 Steel Deck Units

    32. BCN3611 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. BCN3611 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. BCN3611 34 Cold-formed steel

    35. BCN3611 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

    36. BCN3611 36

    37. BCN3611 37 Miscellaneous Metals Ladders (VLF) Metal Stairs (LF or each flight) Handrails or Railings (LF) Gratings (SF) Floor Plates (Lb)
