Steel 90 Degree Joining Plate for 2020 Aluminum Profile

Steel 90 Degree Joining Plate for 2020 Aluminum Profile

The steel 90-degree joining plate is designed to form a sturdy right-angle connection between two 20 × 20 mm (2020 series) aluminum profiles. The flat plate, with its two legs meeting at a 90° corner, serves as a rigid bracket that bridges the profiles, ensuring the joint remains aligned and structurally stable. Manufactured in steel and finished with a protective coating, it supports both assembly and long-term durability in modular framing systems.

With pre-drilled holes sized for M5 or equivalent fasteners and arranged to match standard profile spacing, the plate enables straightforward installation without the need for custom fabrication. Its steel body resists bending and flex under load, helping maintain the right-angle geometry and preserving the structural integrity of the frame. The compact dimensions (typically ~60 × 60 mm) allow it to be discreetly integrated into assemblies without excessive bulk.

Whether used in machine frames, automation cells, 3D printer enclosures or DIY modular projects, this joining plate serves as a reliable interface component. It helps builders achieve repeatable, stable 90° corner joints, simplifying construction and reinforcing the frame at critical junctions. Its steel construction and finish protect against wear and environmental factors, making it a dependable element for both prototype and production-grade assemblies
