Wall Calculator Tips - How-to
Single Height Walls: The calculator is designed for single-height walls, where each new wall represents a turn (e.g., L-shaped or U-shaped walls).
Different Wall Heights: If your wall has varying heights, you can still use the calculator! Just treat each height as a different wall. The calculator will account for two C posts for a turn. For example:
- Wall 1: 400mm high with an 800mm C post.
- Wall 2: 600mm high with a 1200mm C post.
You can swap the 800mm and 1200mm C posts for a single 1200mm H post to change it from a turn to a straight.
Versatile Use: The calculator accommodates different wall heights, widths, and sleeper sizes. However, we recommend verifying the calculations with your engineer or our experienced team.
