Steel Grating Weight Table of Welded and Press Locked Types for Floor

Steel grating picture shows the detail information.

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.
