Standard Shade Sail & Shade Canopy Specifications

Quality Assurance
The steel frames and related concrete foundations for the shade canopy shall be designed in conformance with the 2007 Uniform Building Code as follows Wind Design Speed: up to 100 miles per hour per local requirement.

Steel
All carbon structural steel shall be ASTM A500 or A513 , except steel pipe columns, which shall be ASTM A-53, grade B, unless otherwise noted. Plate steel shall conform to A36, Grade B.

Tensioning Cable
Shall conform to ASTM A-603.
Steel cable size is determined based on calculated engineering load.

Fabric (See "Fabrics" page for more specifications)
High-density polyethylene to block out more than 90% of ultraviolet rays.
Monofilament and tape construction giving stable material.
Minimum fading allowed after 5 years, except for red, which does not have a fading warranty.
All corners shall be strengthened with 15 oz non-tear vinyl material.

Thread
Shall be high density, low shrinkage, abrasion resistant, unaffected by cleaning agents, acid rain, mildew, chlorine, saltwater and industrial pollutants.

Coatings

Non-galvanized Steel
Where sizes of canopy or determined loads require larger structural steel members or greater than 7 gauge thickness, carbon steel may be substituted. Cleaning and coating of carbon steel shall conform to the following:

• Iron phosphate rinse to create a conversion layer on the steel.
• Pre-bake in oven at 350-400 degrees to burn off additional contaminants.
• Powder coat with TGIC polyester powder primer then a top coat.

Pre-galvanized Steel
Steel already has a triple layer of zinc protection with a polymer clear coat, which acts as a primer.

• Pre-bake in oven at 350-400 degrees to burn off additional contaminants.
• Powder coat with TGIC polyester powder top coat.

Warranty
The structural integrity of the steel shall be warranted for twenty (20) years.
The fabric and sewn composite shade covering shall have a pro-rated warranty of ten (10) years.
