FAQ's

High Quality Fabric: Built to last with a distinct geometric appeal, our Equilateral Triangle Shade Sail is anything but standard. Designed and manufactured in our custom facility, each sail combines precise symmetry with premium construction to ensure long-term performance and visual impact.

The equal length of all three sides creates uniform tension across the sail, resulting in a secure, stable install with minimal movement when correctly tensioned. Subtly curved edges further enhance this effect, helping the sail maintain a tight, refined profile over time.

A reinforced 38mm webbing edge is triple-stitched into the fabric using UV-resistant PTFE thread, ensuring exceptional strength and durability.

Each corner is finished with a 316 marine-grade stainless steel D-ring, reinforced with multiple layers of webbing for dependable mounting points. Available in premium fabric options including Extrablock and Shadetec, and a wide range of colours, this sail offers excellent UV protection while complementing a variety of architectural and landscape styles.

Whether used individually or as part of a layered design, the Equilateral Triangle Shade Sail is an elegant solution for creating structured, visually striking shade.

Installation Guide

Step 1: Choose the Right Location.

Before installation, select an appropriate location that offers sturdy anchor points and provides the coverage you need. Consider:

• Sun Exposure: Ensure the sail provides shade where it’s most needed.

• Anchor Points: Identify strong structures like walls, posts to serve as your sail’s support.

Step 2: Gather Tools and Materials

Ensure you have everything needed for a smooth installation:

• Shade Sail in your preferred size and shape.

• Fixings and Hardware such as turnbuckles, D-shackles, eye bolts, and pad eyes.

• Posts (if no existing anchor points are available).

• Tools like a drill, wrench, measuring tape, and ladder.

Step 3: Prepare the Area.

Clear the designated space to ensure an easy and safe installation. Remove any obstacles, furniture, or debris and confirm the area is accessible for securing anchor points.

Step 4: Install Anchor Points

Strong, secure anchor points are essential for a durable installation. Here’s how to set them up:

Using Existing Structures

• Walls or Beams: Drill holes and attach eye bolts or pad eyes into a solid surface like timber , steel or concrete . Brick masonary is not normaly reccomended. Ensure the fixtures are firmly secured to handle tension.

Installing Posts

• Placement: If posts are needed, position them to align with the shade sail’s attachment points.

• Setting Posts: Dig holes one-third the length of the posts and fill with concrete for stability. Allow the concrete to cure fully before attaching the sail.

Step 5: Attach the Shade Sail

With anchor points in place, it’s time to secure the shade sail:

1. Start with One Corner: Attach one corner of the sail to an anchor point using a D-shackle or turnbuckle.

2. Continue Around the Sail: Repeat the process for the remaining corners, connecting each to its anchor point.

3. Secure Tightness: Gradually tighten turnbuckles to ensure the sail is taut but not over-stressed.

Step 6: Check Fixings for Security

After securing the sail, inspect all connections to ensure they are tight and stable:

• Tighten turnbuckles to eliminate slack.

• Check for any loose bolts or fittings.

Step 7: Perform Final Adjustments

Make any necessary adjustments to ensure the sail is evenly tensioned:

• Alignment: Ensure the sail is evenly stretched between anchor points.

• Stability: Verify that all fixings are secure and capable of withstanding wind and weather.

Step 8: Maintain Your Shade Sail

Regular maintenance keeps your shade sail in top condition:

• Clean Periodically: Use a mild detergent and water to remove dirt and debris.

• Inspect Fixings: Check for signs of wear or rust and replace damaged components.

• Re-tension When Needed: Over time, the sail may stretch slightly, so tighten the fixings as necessary.
