Understanding Your Results

01
Estimated Wind Load

The estimated wind load acting on the structure based on the specific project dimensions and regional wind speed ratings.

02
Corner Tension Forces

Total tension force applied to corner sails and anchor points, necessary for determining safe hardware and mounting requirements.

03
Load Distribution

Breakdown of how calculated tension and wind forces are distributed among corners and anchors, facilitating structural planning.

Structural Design Considerations

High-tension shade sails must be designed to handle significant loads. Proper structural design is critical for safety and performance.

  • Footings/piers must be designed for calculated loads.
  • Pole size (diameter, wall thickness, and gauge) must match load requirements.
  • Poles must be protected from weather and corrosion.
  • Posts can be embedded directly into concrete or mounted using anchor bolts.
  • Footer width and depth depend on soil conditions and load requirements.
  • It is strongly recommended to hire a qualified engineer to design foundations and structural supports.

Material & Environmental Load Guidelines

Snow and Ice Loads

Rated for 5 lbs per square foot accumulation.

Fabric Wind Ratings

Typically between 35 mph to 115 mph, depending on manufacturer. Always verify manufacturer specifications before installation.
