Check Latest Price on AmazonWhich One Should You Choose?
If budget is tight → choose ColourTree Grey 6' x 85' (ASIN B07PFRLQXY) and use galvanized hardware for inland shade sails. If you need a compact or trial panel → choose the smaller ColourTree Brown 6' x 56' (ASIN B07665LCN9) (note: zip ties may not be included). If premium durability and coastal pairing matters → choose ColourTree Black 6' x 120' (ASIN B078WL1FZG) and specify 316 stainless turnbuckles, shackles and cable to maximize corrosion resistance and tensile strength.
Best for Specific Scenarios
- Coastal patios and seaside decks: ColourTree Black 6' x 120' (B078WL1FZG) because the heavy 170 GSM fabric plus extra stainless grommets make it easier to secure to 316 stainless hardware for long life by the sea.
- Budget backyard shade: ColourTree Grey 6' x 85' (B07PFRLQXY) because it keeps costs down while still offering UV‑stabilized, reinforced fabric you can attach with galvanized or lower‑grade stainless fittings inland.
- Large coverage with fewer seams: ColourTree Grey 6' x 123' (B07PFRLZ6L) because longer runs mean fewer joins and more continuous attachment points for cable and turnbuckle systems.
Frequently Asked Questions
Should I buy stainless or galvanized turnbuckles for a seaside shade sail?
For seaside and coastal installs choose 316 stainless steel for turnbuckles, shackles and cable — it resists salt‑water corrosion far better than galvanized or 304 stainless. Galvanized can work inland but will deteriorate faster in salt air.
What cable diameter and breaking strength do I need?
Match cable diameter to span and wind exposure. Small sails often use 3–5 mm (1/8"–3/16") cable; larger sails use 6 mm (1/4") or more. Always apply a safety factor (commonly 4:1) to expected peak loads and choose hardware with a working load well above that number.
Can I use these ColourTree screens as my shade sail fabric?
Yes — the 170 GSM HDPE screens are UV‑stabilized, breathable and have reinforced grommets and binding designed for outdoor shade and privacy. They’re best used with separately purchased turnbuckles and cable sized for your installation.
