How to Make a Door Threshold Yourself

Today, we are going to see how to make a door threshold yourself.

First of all, you need to choose the metal suited to its application. To avoid slips, it is better to use plates with texture, such as the non-slip aluminum. With a thickness of 4 mm, it is rigid enough to support the passage of a person, provided you fix your plate to a support by welding or with screws if there is a gap underneath. So you can use it in front of the house, or in the garden for example.

To fill a groove in front of your garage, choose non-slip steel that can support the weight of a light vehicle. You will need to treat it against corrosion with a galvanization spray can or a John Steel anti-rust paint.

Ludo actually sent me a nice photo of his project, which he had custom cut by John Steel.

The goal of this project was to fill the gap between my house and my garage, about 10 cm. I first screwed the aluminum plate onto a support with 3 screws and then glued a plastic corner to hide the underside of the door, followed by finishing silicone for the various angles."

That’s some beautiful work, Ludo!

Don’t hesitate to share your great ideas and send me photos to appear on the John Steel blog!

See you soon!

Bonjour
c'est à peu près ce que je recherche, une plaque alu de 117 x 17mm et 2mm d'épaisseur suffirait puisqu'elle ne ferra que recouvrir un seuil existant.
Pouvez-vous me faire une offre, je m'occuperai des découpes aux extrémités

Replied by: John Steel On 2021-06-25 Bonjour Jean-Pierre,
Dans votre situation, effectivement c'est un très bon choix. Comme le but d'un seuil de porte est de protéger, une épaisseur de 2mm est suffisante. Pour vous permettre d'avoir une estimation la plus juste je vous conseille de passer par notre configurateur (https://www.john-steel.com/fr/configurateur) qui vous permettra également de faire les découpes aux extrémités. Si vous avez besoins de plus d'informations, n'hésitez pas à prendre contact avec notre SteelTeam.
Bon bricolage,
John
