2. Main Features & Advantages

Genuine Stainless Steel Material
Every corner cleat is made from authentic stainless steel. The 201 grade works well for standard indoor applications, while the 304 grade provides superior protection against rust and moisture, making it ideal for outdoor or coastal installations.

Three Anti-Slip Embossed Dots
The surface features three raised dots that grip the frame profile firmly. This design increases friction between the cleat and the material, preventing unwanted movement during assembly. The wider contact area also helps distribute pressure evenly, reducing stress on any single point.

Smooth Polished Surface
Each piece receives a polished finish that looks clean and professional. The smooth surface resists dirt, wipes clean easily, and feels pleasant to touch during installation. No rough patches or sharp edges.

Clean Burr-Free Edges
Using precision stamping equipment, we produce corner cleats with flat, even edges. There are no burrs, no uneven corners, and no rough spots that could scratch profiles or hurt installers. This attention to detail makes assembly faster and safer.

Wide Compatibility
These corner cleats work with various frame types, including aluminum, uPVC, and even wooden profiles. They are commonly used in casement windows, sliding windows, top-hung windows, aluminum doors, and some furniture applications.

Factory Direct Availability
As an original equipment manufacturer, we keep substantial inventory ready for shipment. Bulk orders, custom specifications, and urgent requests are all handled efficiently through our streamlined production and logistics system.
