Handmade with Love in Canada
A Quadrilateral Shade Sail is optimum for maximum amounts of shade and for covering long spaces where a triangular Shade Sail would not suffice. Your Quadrilateral Shade Sail can also be flown with varied anchor points; fly your sail with contrasting heights on the opposing corners for an eye-catching hypar shape.
Our Premium Shade Sails are manufactured in Canada using UV stabilised high-density polyethylene (HDPE) shade fabric and UV stabilised sewing thread. Each corner is reinforced using multiple layers of shade cloth and stainless steel rings.
Shade Sails Canada guarantees its products and we only deal in optimum quality. Trained by experts in the field in Australia, our knowledge and expertise is our biggest asset in our ability to deliver the best quality Shade Sail; we guarantee it.
Custom Shade Sails are available in over 50 fabric/colour combinations. Choose between waterproof and high-end commercial fabrics in whatever size you like.
Marine-Grade Stainless Steel
Our Shade Sails hardware kits contain all of the hardware you’ll need to fly your sail. All of our hardware is high load rated and made from marine grade stainless steel, offering the highest quality for all conditions. Your Quadrilateral Hardware Kit will include:
- Four Kwik Klips
- Two 3/16″ twist “D” shackles
- Two 1/4 inch Turnbuckles
- Four 1/4 inch “D” shackles
Kwik Klips are used on each corner of the sail, connecting either your turnbuckle or your D-shackle to your attachment point. Kwik Klips are specifically designed to allow for great ease when putting up and taking down your Shade Sail. Turnbuckles are used to tension your Shade Sail properly and allow for easy and efficient adjustment during the season. ¼ D-shackles attach your turnbuckles to your Kwik Klips and the corners of the sail and the longer 3/16 twist D-shackles are used to attach the remaining Kwik Klips to the corners without turnbuckles.
Please note, anchor point hardware will need to be purchased separately, you can view this here.
Advanced Tensioning System
Stainless Steel Cable
All premium shade sails come with our Advanced Tensioning System as standard. The ATS system consists of a stainless steel cable ensuring equal tensioning, increased water run-off and zero -stretch, lengthening the life of your Shade Sail. Each sail also comes with cable clips used to secure the tension in the cable.
Ready to Fly
If you’re purchasing hardware with your Shade Sail (which we highly recommend) we now offer the option to have your hardware preassembled and attached to each corner before it is shipped, saving you time and reducing errors when installing.
FAQs & Important Information
Are the sides of a shade sail straight or curved?
The sides of a shade sail are curved to ensure proper tensioning. The amount of the curve (catenary curve) depends on the shape of the shade sail and can be adjusted when ordering a custom shade sail. Curvature is not solely for tensioning purposes, it can be increased (to go around a tree or other obstruction) or decreased in some cases. Our design software automatically optimizes the catenary curve for each design. Please get in contact with our design team for any unique requirements.
Are shade sails waterproof?
Most shade sails are not waterproof unless you are using a waterproof fabric, however, one of the reasons we suggest varying the heights of your posts/attachment points is to encourage water run-off. When your sails are sloped and tightened correctly, the majority of the water will run off to the side of the sail, with only a fine mist making it through the mesh. Heavy rain is not an issue if the sail has a significant slope and is very tight.
