Construction: Vee-WireŽ Welded Wire Screens |
|
| In making a Johnson
welded wire screen, a long single wire is wrapped spirally
around an array of support rods leaving a very narrow space
between each wrap to create a continuous slot opening. Each time
the surface wire crosses an internal support rod, it is
automatically welded. The end product is an extremely strong
cylinder with excellent column, beam, burst and collapse strength.
The continuous slot opening, combined with the narrow face width
of the wire, creates a very large percentage of open area in the
screen. |
