Steel 90 Degree T-Joint Plate for 2020 Aluminum Profile

Steel 90 Degree T-Joint Plate for 2020 Aluminum Profile

The steel 90 degree T-joint plate for 20×20 mm (2020) aluminum profile is a precision-formed bracket designed to provide a robust right-angle junction between two profile members. Constructed of steel, the plate features a flat L- or T-shaped geometry that fits seamlessly at the corner of a modular frame. Its design ensures that structural members can be joined at 90°, maintaining alignment, stability and continuity in the build.

The bracket’s steel construction ensures that it can withstand mechanical stresses and repeated assembly/disassembly without deformation. With pre-drilled mounting holes aligned to standard fastener spacings for 2020 profile systems, the plate simplifies installation and ensures reliable connection. The finish, often black electrostatic paint, offers corrosion protection and a clean appearance, meaning the joint remains mechanically sound and visually consistent over time.

Whether used in machine frames, 3D-printer builds, workstations or structural enclosures, this T-joint plate acts as a foundational structural component. It allows designers and builders to quickly establish right-angle connections without fabricating custom brackets. By enabling precise alignment and rigid joint stability, it enhances the overall structural integrity of modular aluminum systems and streamlines assembly in industrial, prototyping and DIY applications.
