• Commercial display / heavy items → 2.5 mm

1.4 45° Corner Brackets + 4-Screw Locking – Why It’s Different

Most ordinary aluminum frames use simple L-brackets or 2-screw joints. Over time, repeated opening and closing causes:

• Micro-movements at the joints

• Growing gaps at the corners

• Doors going out of alignment

• Dust and grease entering through invisible openings

This T6063 frame uses a dedicated 45° corner bracket system with 4 screws per corner:

• 45° joint design creates a clean, continuous visual line around the frame

• 4-screw locking increases corner stability by up to 3× compared to 2-screw systems

• Seamless, gap-free splicing prevents dust, grease, and moisture from seeping into cabinets

• Tighter joints keep doors aligned, even under high-frequency use

For applications such as restaurant kitchens, high-traffic retail stores, and office storage rooms, this structure significantly reduces the risk of loosening, squeaking hinges, and misaligned doors over time.
