Aluminum Vs. Cast Aluminum Furniture

When it comes to choosing aluminum furniture, there are two main types to consider: hollow (or extruded) and cast (solid). Understanding the differences between the two can help you make the best choice for your needs.

Extruded Aluminum Furniture

Most hollow aluminum sets undergo a process called extrusion, where a piece of metal is forced through a machine that shapes it into a hollow, round, or square frame. Here are key factors to consider for good quality extruded aluminum:

Quality Differentiators

• Weight: Heavier chairs indicate higher quality material, which means better support and less likelihood of being blown away. However, lighter chairs are easier to move, which can be advantageous for seniors or families with children.
• Support: Because extruded aluminum is hollow, it is more prone to dents and bending. Some manufacturers add internal supports to prevent these issues.
• Techniques: High-quality powder-coating involves cleaning the metal surface, applying a powder paint with a Corona gun, and then baking it for a glossy finish. Lesser techniques involving standard paint can result in peeling and less durable finishes.
• Welding: Some manufacturers use brass for welding joints instead of aluminum or steel. A combination of aluminum, zinc, and steel is often used for welding in better quality pieces.
• Storage: Most extruded aluminum sets are stackable and designed for winter storage to prevent freeze damage, offering an easy and protective storage solution.

Cast Aluminum Furniture

Cast aluminum sets are formed by pouring hot molten metal into a cast frame. This method allows for more intricate designs and provides greater stability since there are no hollow components. Key quality differentiators for cast aluminum furniture include:

Quality Differentiators

• Fillers: Some manufacturers use fillers that make aluminum less dense, which can lead to cracks and breakage. High-quality brands like Hanamint and Gensun offer pure aluminum options with long-term warranties.
• 3D Molds: High-quality cast sets are finished on all sides, ensuring an attractive appearance from any angle, while lower-quality sets may only be finished on one side.
• Weld Sanding: Properly sanded welds contribute to the overall strength and appearance of the furniture. Inadequate sanding can result in weak joints.

For those in windy areas or looking for a long-lasting product, cast aluminum is a wise choice. In contrast, extruded aluminum is ideal for lightweight and easy-to-move furniture.
