ESTA E1.76 PDF

This standard for tension wire grids covers the design and application criteria including: the loading, self-weight considerations, transitions between levels, and suspension or support from structure.

The standard provides deflection criteria for the woven mesh and structural frame as a walking/working system. The standard provides guidance on the size of openings permissible in the surface.

The scope includes fall protection and edge protection for the entirety of the walking/working surface, including platforms, ramps and stairs.

The standard provides consideration for accessories such as stage lighting pipes.

This standard does not apply to the structure to which the tension wire grid is attached.

Movable panels, used as part of the stage floor, trap covers, or pit fillers are outside the scope of this standard.

Movable panels, used as part of the stage floor, trap covers, or pit fillers are outside the scope of this standard because their frames are supported in many fashions, frequently without pinning the corners. In addition, the required loading for stage floors is 150 pounds/square foot (7.2 kN/m²).
