Patio Umbrella Bases and Stands

Patio Umbrella Bases and Stands

 

Choosing a suitable base or stand is critical to ensure that your patio umbrellas are stable and upright under any condition. Our Patio Umbrella Bases and Stands are just what you need to keep your picnic tables and benches and outdoor table and chair sets looking trendy and stylish. Find a variety of styles, sizes, and materials to suit your needs.


Q1: Why is the weight of an Umbrella Stand the most critical safety factor?


A: The stand's weight must counteract the large upward force created by the umbrella canopy in the wind.

  1. Wind Load: An open umbrella acts like a sail. The larger the canopy, the greater the force the wind exerts, attempting to lift the umbrella out of the stand and overturn it. This force is what we call 'wind load,' and it's crucial to choose an umbrella stand that can counteract it.

  2. Weight Requirement Rule: 

    1. Freestanding Umbrellas (Cantilever or Center): Requires the heaviest base, ideally over 100 pounds.

    2. Table Umbrellas: The table provides some support, but the base should still be substantial, ideally 50 to 75 pounds for a 9-foot umbrella.

  3. Tipping Risk: An inadequately weighted stand creates a significant hazard, as the umbrella can become airborne or crash into people or property.


Q2: What materials are commonly used for heavy umbrella stands, and what are their specific advantages?


A: Materials must be dense and weather-resistant to achieve the necessary weight.

  1. Concrete/Stone: Offers the highest density and weight. They are highly stable and resist movement, but they are cumbersome to move and may crack in freeze-thaw cycles if not correctly sealed.

  2. Cast Iron/Cast Aluminum: These metal bases are heavy and durable. Cast iron is the heaviest but prone to rust if the finish is scratched. Cast aluminum is rust-proof and slightly lighter.

  3. Resin/Plastic: These are empty and must be filled with sand or water to achieve the necessary weight. Sand is preferred over water as it provides more density and won't freeze in winter.


Q3: What critical feature must an Umbrella Stand possess to accommodate different pole sizes?


A: The stand must have a mechanism to grip poles of varying diameters securely.

  1. Tightening Mechanism: All good umbrella stands use a thumb screw or locking pin that tightens around the pole. This screw must be tightened securely to prevent the pole from wobbling, spinning, or swaying.

  2. Sizing Inserts: Many stands include interchangeable plastic sizing rings or adapters. These rings fill the gap between a thinner pole and the stand's wide collar, ensuring the thumb screw can achieve a secure grip on poles from 1 to 2 inches in diameter.

  3. Pole Height: Ensure the pole extends far enough into the base for maximum stability.


Q4: What specialized stand is required for a Cantilever (Offset) Umbrella?


A: Cantilever umbrellas require a unique, extremely heavy-duty base due to the weight offset.

  1. Rolling/Segmented Base: These bases are large, often square or cross-shaped, and are typically filled with multiple weighted sections (water or sand). The weight requirement generally is over 150 to 200 pounds.

  2. Integrated Wheels: Due to the extreme weight, many cantilever bases include integrated wheels that allow the base to be rolled into position before filling or securing.

  3. Mounting: Some cantilever umbrellas can be permanently bolted to a patio surface or deck for the highest level of stability.
