Materials & Construction

High-Strength Steel Profiles

The window frame is manufactured using galvanized steel profiles. The frame uses 1.5 mm steel sheets, while the sash uses 1.2 mm steel sheets.

Precision cold-forming technology creates a closed steel profile structure designed to provide excellent structural strength and stability.

Fire-Resistant Glazing

The system uses high-performance Class A fire-resistant glass designed to provide both thermal insulation and fire protection.

Different glazing configurations can be discussed according to individual project requirements.

Fire-Rated Hardware

Fire-rated hardware from established manufacturers can be selected according to project specifications.

Available hardware configurations may vary depending on window size, opening method, and fire-performance requirements.

Durable Surface Treatment

A controlled pre-treatment and coating process is used to improve:

• Weather resistance

• UV resistance

• Chemical resistance

• Wear resistance

Custom surface finishes and colors are available for different architectural designs.

Fire Performance

Two fire-resistance configurations are available:

90-Minute Fire Resistance
