A huge advantage of aluminum profiles is the ease with which they can be joined together. All that is needed here is the right components that securely fasten the aluminum profiles together.
Brackets are the most popular connector for aluminum profiles. Brackets are designed for connections at 90 degrees. Fixing the bracket is simple, requiring only a few nuts and bolts and no additional machining of the profiles. This angle connector for aluminum profiles is fixed as follows:
- To prepare the connection, you need two aluminum profiles precisely cut at 90 degrees. It makes sense to install the bolt and the nut lightly attached to it in the bracket beforehand.
- Then arrange the profiles one on top of the other at a 90° angle and place the bracket at the connection point so that the tabs on the back of the bracket settle into the groove of the profile.
- The bolt and nut are then properly turned so that the hammer head is inside the profile. You must make sure that the hammer head remains in the correct position inside the groove.
- For a 30x30 aluminum profile, U8 hammer nuts are used along with an angle head screw. For aluminum profiles 40x40 and larger, U10 hammer-head screws are used along with flange nuts. Connecting aluminum profiles with external brackets has many advantages. These are flexibility and adaptability, as they can be easily placed or moved to another location. On the other hand, the main disadvantage is not very aesthetic appearance and space required.
A more elegant solution is to use corners. They are more aesthetically pleasing and connect aluminum profiles with equal ease. However, these connectors are more expensive and limited to only a few combinations of aluminum profiles: 30x30, 40x40 and 45x45. Also note that the thread must be made inside the profile before installation. Connector for aluminum profiles included Sometimes there is a need for an unconventional connection when it comes to aluminum profiles. Fasteners in this case are available in specialized kits. The connections they create are strong, but require some work before installation, from drilling holes in the profile for inserts to forming threads for screws. Bolt connectors are used to join two bolts together for a stronger connection. Their installation requires drilling a hole in the entire profile. For example, an aluminum profile milling connector is designed to make profile connections at 90 degrees or 0 degrees. Like screw fasteners, they create a strong connection. However, this angle connector for aluminum profiles requires drilling. Face connector sets The most basic connecting elements are face connector sets. This type of aluminum profile jointing is ideal for less demanding applications and is used very often. They can withstand loads of 800-1000 N and moment loads of 40 Nm. Face connector kits are available in two sizes. The first is designed for aluminum profiles with an 8 mm notch (size 30x30), and the second for aluminum profiles with a 10 mm notch (size 40x40 and larger). Their installation requires drilling a hole in one profile and making a thread in another. The main advantage is that such a connector is hidden and does not require additional space. It also provides good rigidity and resistance to vibration. The disadvantage is the need for additional machining of the profile, which at the same time makes it impossible to move such a connector.
When long profiles are needed, but the cost of transporting them is too high, it makes more sense to cut them into smaller pieces and then connect them using linear connectors. A linear connector is basically a T-shaped nut with a long length. The T-shape is designed to fit into the slot of the aluminum profile. Before using this solution, double-check the load-bearing capacity of the linear connector joint. From the point of view of rigidity, it is always better to use an aluminum profile consisting of one part.
