Dimensional Key

Design Moments and Foundation Size.
The foundation data provided details concrete diameters and block sizes based upon the maximum capacities stated in
the headload table. Please note however these headloads are showing the maximum achievable on the column to give
an indication of the columns carrying capacity for additional equipment. If columns are being used for luminaires only the
foundation sizes will reduce significantly. Please enquire to ascertain project specific foundation guidance based on intended designs.

Planted Root Columns: The data given in these tables in regards to minimum surrounding concrete diameters of foundations
is based on upon the ground pressures given for the 3 soil types identified in Table 2 of PD6547:2004. The calculation
method given in this standard has therefore been applied using the poorest soil conditions with a ground pressure of 230
kN/m2 to give a figure for guidance only. More site specific calculations can be carried out at point of enquiry where site soil
conditions are known.

Flange Plated Columns: The concrete foundation sizes given in the table above have been calculated using the Andree &
Norsa method with a ground pressure of 20 N/cm2 and has been given for guidance only. Site specific calculations should
be carried out where the ground pressure in the vicinity of the lighting column is known.

Understanding The Tables.
Valmont Stainton produces a wide range of columns in many different shapes and sizes. The graphics below will help to
define the dimensional abbreviations used throughout this brochure. Any dimensions or design aspects that are specific to
a given model with be noted on the product page.
