An important aspect for your new steel garage is to accurately determine the wind speed for your region, so that we can engineer your building according.

Put in a nutshell, the wind speed is basically the air moving from high to low pressure, and this pressure may have a detrimental impact on your shed if your shed has not been engineered appropriately for your site. By determining the wind speed for our region, we are better equipped to supply a shed that will withstand what the climate in your area gives out.

There are a few factors that that we look into at this stage, in order to get the most accurate details. They include:

Regional Wind Speed

There are 4 main variables that are taken into account when determining the wind classification for the site of your shed, they are:

  1. Terrain Category
  2. Region
  3. Shielding Factor; and
  4. Topographic Classification.

Terrain Category

The terrain category is broken up into 5 main categories, and it looks at how the terrain flows and how it impacts on your building. Category 1 indicates a terrain with little to no obstruction and terrain category 3 identifies a terrain with a multiple obstructions – such as suburbia.

Topographic Factor (1 = lowest value)

When determine the topographic factor, we look at how the wind is affected by hills and escarpments; we do this by assessing the slope, direction and altitude of the site.

Shielding Factor (1 = highest value)

The shielding factor is determined by structures such as trees and houses of similar size that shield your steel building from wind. There are a total of three shielding factors, from full shielding, partial to no shielding.
