Joining aluminium angles can be achieved through various methods, with the simplest often involving mechanical fasteners like brackets.
Aluminium angles can be joined using several techniques, depending on the required strength, aesthetics, and complexity of the joint.
Using Brackets
One of the most straightforward methods, particularly for creating 90-degree connections, is using brackets.
- Simplicity: As referenced, The most basic ones are brackets. They are designed specifically for rigid connections, often for 90-degree angles.
- Attachment: Attaching a bracket is simple, it only requires a couple of screws and nuts. This method is user-friendly and doesn't require specialized welding skills or complex tools.
- Preparation: To prepare the joint with brackets for a 90-degree connection, you need two aluminium profiles precisely cut at an angle of 90°. The bracket typically fits over the junction of the two angles.
- No Machining: Using brackets generally does not require additional machining of profiles beyond cutting them to the correct length and angle.
Other Joining Methods
While brackets are basic and effective, especially for structural frames or simple supports, other methods are also common:
- Welding: Welding provides a strong, permanent joint but requires specialized equipment and skill (e.g., TIG welding for aluminium).
- Fasteners: Beyond simple brackets, various bolts, nuts, screws, and rivets can be used to mechanically fasten aluminium angles together. This often requires drilling holes through the angles.
- Adhesives: Structural adhesives formulated for metal can be used for joining, offering smooth surfaces and potentially reducing stress points compared to drilling. This method's suitability depends on the load requirements and environmental conditions.
Choosing the best method depends on the specific application, desired strength, appearance, and available tools or expertise. For quick, easy, and strong 90-degree connections, brackets are often an excellent choice.
