Frequently Asked Questions
Are spiral ground anchors better than simple stakes for windy areas?
Yes. Spiral (helical) anchors distribute uplift along the screw body and bite into soil more effectively than straight stakes, giving far better resistance to high winds when installed correctly.
Which material is best for coastal decks exposed to salt spray?
Stainless steel (304 or 316) is the best choice for coastal exposure; hot-dip galvanized steel with a quality coating is a lower-cost alternative but will need more maintenance over time.
What size cable and turnbuckle should I use?
For medium to large canopies and fixtures, choose at least 3/16" galvanized cable with matching turnbuckles rated for the load. For light shades and temporary uses, 1/8" cable is often sufficient. Always verify hardware capacity relative to expected wind loads.
