The Shady Ladies always recommend that you get your shade sail first before installing your fixing points.
Steel posts are widely used for Shade Sail installation. They can be sourced from local steel fabricators as they would need to be delivered and this would save on delivery costs if any. You are best to contact a few to find the best price. Standard posts are 4mm 90mm galvanized posts and 1/3 of the post should be concreted in the ground for standard sun shade sail use. Wooden posts are also used but we are not able to advise which wooden posts are suitable, you will need to check with the supplier and let them know what the shade sail size is you are erecting.
Other resources to find 2nd hand posts - gumtree, eBay, local trading posts.
