Load Deflection Tables
DEFLECTION TO SPAN RATIOS

• For a resilient, non-fatiguing, comfortable feel use the STANDARD deflection to span ratio of 1:120.
• For an elevated installation, where a solid feeling is desired, use a deflection to span ratio of 1:180 (NBC-85).
  A deflection to span ratio greater than 1:100 (1%) is not recommended. Do not exceed .5" (13mm).

PANEL SELECTION

• Determine the type of loading: concentrated or uniform.
• Estimate the load and determine the span.
• Decide what maximum deflection is appropriate solid, standard or 1%.
• Enter the appropriate 1" (25mm) table. If the deflection is less than the maximum selected, choose the 1" thickness.
• It is more economical than 1.5" thick panels. If the deflection or span is too great for 1" thick panels, select 1.5" thick   FRP Grating and design your support system for the appropriate span.
• Select the resin system.

PANEL INSTALLATION

• Panels are designed to be supported on all sides.
• Use end clips if panel ends cannot be supported.
• Use hold down clips to prevent panel drift.


Click to open the Unifrom Load Table in a new window Uniform Load Table

Chart to determine panel sizes for loads that are distributed uniformly over a portion or over the entire panel.

Click to open the Concentrated Load Table in a new window Concentrated Load Table

Chart to determine panel sizes for loads that are negligible due to a small contact area or a load acting on a very small area of the panel structure.
