Flange base
Available in a round or square shape and screwed to the ground (the surface where the base will be placed must be at least 10-15 cm thick in cement). To fix the flange we use galvanised or stainless steel plugs 12 mm thick and 14-20 cm long depending on the size of the umbrella. Flange diameter in two types: 25 cm and 8 mm thick and tube Φ60 (suitable for heavy duty umbrellas), and 30 cm and 1 cm thick and tube Φ90 (for super heavy duty umbrellas). The ideal base for great stability; it can be made in several variations such as with extra reinforcements, with a decorative top, with an anchored flange, etc.
