Aluminum square tubing and channels are versatile materials used extensively in various industries, from construction and manufacturing to automotive and aerospace. Their lightweight yet strong nature, combined with corrosion resistance and ease of fabrication, makes them a popular choice for a wide array of applications. This article provides a comprehensive overview of aluminum square tubing and channels, focusing on sizing, pricing, availability, and application considerations. We'll delve into the specifics of different sizes, explore where to find them, and discuss the factors influencing their cost.
Understanding Aluminum Square Tubing and Channels
Before delving into the specifics of size charts and pricing, let's clarify the distinction between aluminum square tubing and aluminum channels. While both are extruded aluminum profiles with square cross-sections, there are key differences:
* Aluminum Square Tubing: This refers to hollow square profiles with a consistent wall thickness throughout. They are typically used for structural applications where strength and rigidity are paramount. Think of the frame of a small piece of equipment or the support structure for a light fixture.
* Aluminum Channels: While often square in cross-section, aluminum channels are characterized by a distinct difference in wall thickness. They frequently have one or more flanges (wider sides) and a thinner web (the connecting portion). This design optimizes strength in specific directions, making them ideal for applications requiring load-bearing capacity in particular orientations. They are often used as framing components, mounting rails, or guides.
Both square tubing and channels offer excellent strength-to-weight ratios, making them suitable for applications where weight is a critical factor. They are also easily machinable, weldable, and can be finished with various coatings for enhanced aesthetics and corrosion resistance.
Aluminum Channel Size Chart
An aluminum channel size chart typically lists the dimensions in terms of overall width, height (depth), and wall thickness. The dimensions are usually specified in inches or millimeters. A typical chart might include the following information:
* Overall Width: This refers to the widest dimension of the channel's cross-section.
* Overall Height (Depth): This is the dimension perpendicular to the width.
* Wall Thickness: This specifies the thickness of the channel's walls. This can vary significantly depending on the channel's intended application and strength requirements.
* Weight per Foot: This is a crucial factor for structural calculations and material ordering.
* Material Grade: Aluminum alloys are designated by specific numbers (e.g., 6061, 6063). These numbers indicate the alloy's composition and properties, influencing its strength, workability, and corrosion resistance.
Unfortunately, a single, universally accepted aluminum channel size chart doesn't exist. The available sizes and specifications vary depending on the manufacturer. To find the specific size chart you need, you should consult the website or catalog of the aluminum extrusion supplier you intend to use.
Aluminum Square Tubing Sizes Chart
Similar to aluminum channels, aluminum square tubing sizes are typically specified by their outside dimensions (width and height) and wall thickness. A typical chart will list the following:
* Outside Dimensions (Width x Height): These are the overall measurements of the square tubing's cross-section. Common sizes range from very small (e.g., 1/2" x 1/2") to much larger (e.g., 6" x 6").
* Wall Thickness: This indicates the thickness of the tubing's walls. Thicker walls mean greater strength and rigidity.
* Weight per Foot: As with channels, this is critical for engineering calculations and material estimation.
