Description

Alaks Metal Corner Bracket | 28.5×18 mm

In professional assembly of aluminum doors and windows, the quality of corner joints directly affects the strength, alignment, and long term durability of the structure. The 28.5×18 mm Alaks Metal Corner Bracket is a precise and highly durable connector designed to create a strong 90 degree joint between aluminum profiles. It is widely used in light to semi heavy applications and is ideal for normal hinged systems, light frames, small aluminum windows, and structures where assembly accuracy is critical.

⚙️ Technical Design & Performance:

This corner bracket is engineered to distribute the applied forces evenly once inserted inside or behind the profile.
The 1.8 mm thickness enhances resistance against bending and deformation, preventing the miter joint from opening over time.
The central screw hole enables accurate and secure fastening, ensuring the final joint remains stable, rigid, and free of play.

🧩 Applications:

• Corner connection of frames in normal and thermal break aluminum systems
• Suitable for light to semi heavy aluminum windows and doors
• Ideal for decorative frames, small structures, and narrow profiles
• Can be used with industrial adhesive for extra bonding strength

⭐ Advantages of the Metal Corner Bracket:

✔️ Higher strength compared to plastic brackets
✔️ Accurate retention of the 90 degree angle
✔️ Excellent resistance to pressure and mechanical stress
✔️ Quick and easy screw type installation
✔️ Suitable for mass production and industrial assembly

❓ Frequently Asked Questions:

1. Is this bracket suitable for heavy window systems?

No. This model is designed for light to semi heavy structures. For heavier windows, it is recommended to use Fuji brackets or thicker metal brackets.

2. Can industrial adhesive be used along with the screw?

Yes. Combining screws with industrial adhesive significantly increases the strength of the joint.

3. What is the difference between this bracket and plastic brackets?
