steel-grating-picture

WC-01: Steel grating chart help you understand the structure of welded and press locked grating easily.

  • T: Distance between the bearing bars.
  • Q: Distance between the crossing bars.
  • t1: Distance between the center to center of the bearing bar.
  • q1: Distance between the center to center of crossing bar.

Blue Color figures represents the standard grating.
