Round Tapered Masts - Valmont Seamless Weld Technology

Round Tapered Lighting Masts, Columns and Poles

Today, aesthetics play an increasingly important role when selecting lighting masts for installation in public spaces.

To meet the growing need for attractive lighting masts, Valmont has developed a patented, Seamless Weld Technology (SWT) for conical masts / round tapered poles.

The Valmont SWT process fuses the ends of the circular conical cone without using foreign matter. The seamless weld is flush with the base material and provides an aesthetically attractive round tapered / conical light pole.


Valmont SWT:
  • The new standard 
  • Less CO2 emissions
  • Less zinc build-up
  • Better penetration than old technology 
  • Beautiful, smooth appearance
