Key Features
Five Shape Variants
Available in Y, X, L, T, and A shapes to cover every joint configuration in T-slot aluminum frame construction, from flat cross-joints to angled corner connections.
High-Strength Aluminum Alloy
Manufactured from 6061-T6 aluminum alloy with CNC precision machining, delivering consistent dimensional accuracy and reliable structural performance across all variants.
Silver & Black Anodized Finish
Available in XACC31 (silver anodized) and XACC21 (black anodized) finishes, providing corrosion resistance and a clean, professional appearance for visible frame joints.
Wide Profile Compatibility
Compatible with EU and GB standard profiles from 20 to 50 series, including 206, G306, G408, 4010, 4510, and 5010 — covering the most common industrial profile systems worldwide.
Flush Surface Mounting
Designed to sit flush within the T-slot channel, maintaining a clean external profile without protruding hardware — ideal for enclosures, guards, and aesthetic frame assemblies.
Quick Assembly
Slot-in installation with standard M-series fasteners eliminates drilling and welding, enabling rapid frame assembly and reconfiguration in automated machinery and modular structures.
Typical Applications
Automated Machine Frames
Connect aluminum profile members at flat or cross joints in CNC machine frames, robot cells, and automated assembly lines where rigid, precise connections are critical.
Industrial Safety Guards & Enclosures
Join profile members at T and X intersections to build safety guards, machine enclosures, and protective barriers with clean, flush external surfaces.
Conveyor & Material Handling Systems
Reinforce frame joints in conveyor structures, roller tables, and material handling systems where vibration and dynamic loads require secure, repeatable connections.
Workstations & Ergonomic Benches
Assemble adjustable-height workstations, ergonomic benches, and tool trolleys using Y and L shape plates for stable, reconfigurable frame joints.
Display & Exhibition Structures
Build lightweight, modular display stands, trade show booths, and exhibition frames with A-shape plates for angled corner joints and clean aesthetics.
Cleanroom & Laboratory Equipment
Use anodized joining plates in cleanroom frames, laboratory benches, and medical equipment structures where hygiene, corrosion resistance, and dimensional accuracy are required.
