  2. Anti-slip grating - Wikipedia

    en.wikipedia.org/wiki/Anti-slip_grating

    Anti-slip steel grating is a type of bar grating. Steel bar grating is manufactured in a variety of methods. Welded bar grating consists of load bars electrically fuse welded to cross bars. Pressure-locked bar grating, or swaged grating, is where steel rods are forced through and locked in load bars. Riveted bar grating is where the load bars ...

  3. Double tee - Wikipedia

    en.wikipedia.org/wiki/Double_tee

    The Precast/Prestressed Concrete Institute (PCI) published the double tee load capacity calculation (load tables) for the first time in the PCI Design Handbook in 1971. The load tables use the code to identify double tee span type by using the width in feet, followed by "DT", followed by depth in inches, for example, 4DT14 is for 4-foot (1.2 m ...

    Reference to the load capacity tables provided by the anchor manufacturer is required to make an anchor selection for the specific concrete strengths at the time of lifting. Hence the great of the two calculated anchor capacities required at the concrete strength of the initial lift is normally selected.
