Hidden joist hangers are used as invisable connection elements between woods. The most used version of hidden joist hangers it the EL-60.
We exclusively offer joist hangers of the brand Simpson Strong-Tie. Reason for that is: we are convinced by the quality and the manufacturer- the market leader- comes out with the most innovations for thei field.
We offer hidden joist hangers in to versions: EL or EL-S. The difference lies in the kind of application. The EL connects the main beam with secondary beam connections. The EL-S connects secondary beam connections with supporters. The difference becomes visable through the existing angle of the EL, while the EL-S doesn't have an angle.
Advantages of the hidden joist hangers
The advantage is the except from the top view, invisable connection of the beems. You mainly use this product for optical reasons. But also the installation is faster and easier compared to common joist hangers. The hidden joist hangers are made from aluminium and for this more corrision-resistant (for example against condensation) and more durable than common joist hangers made from galvanized steel.
Hidden joist hangers can be used for connections at bevels 15° to 165°. Standard joist hangers can be used only for connections with an 90 degree angle.
To full-fill the requirements you have to use fully threaded screws from the manufacturer SPAX with the length 60 to 120 mm for the connection. The required screws for the application you can find in the chart below.
If a 90 degree angle works and you are fine with visable connections, you also can alternatively with cheaper Joist Hangers.
If you value completely invisable connections, buy Hidden Joist Hanger ATF.
