High-Strength Steel Construction

The window frame and sash are manufactured using galvanized steel with a thickness of 1.2 mm.

Precision cold-forming technology is used to manufacture closed steel profiles in a single forming process.

The resulting steel profile structure provides high structural strength and stability, making it suitable for demanding architectural and fire-rated applications.

Fire-Resistant Glazing

The system uses high-performance Class C fire-resistant glass.

Glazing configurations can be customized according to architectural dimensions, fire-performance requirements, and individual project specifications.

Fire-Rated Hardware

Specialized fire-rated hardware can be selected according to the requirements of each project.

Available hardware options may include products from established manufacturers such as:

• Kinlong

• Fuerda

• Jieao

The final hardware configuration depends on product dimensions, opening configuration, and project requirements.

Sealing System

The 65 mm steel frame system incorporates double flame-retardant sealing strips.

This sealing structure helps provide good air-tightness and water-tightness while supporting the overall fire-protection performance of the window system.

Surface Treatment

The steel profiles undergo a controlled pre-treatment and coating process designed to provide durable long-term surface performance.

The treatment provides good:

• Weather resistance

• UV resistance

• Chemical resistance

• Wear resistance

Different architectural colors and surface finishes can be customized according to project requirements.

Fire Performance

The system is available with:

60-Minute Fire Resistance

For projects requiring enhanced fire-protection performance.

30-Minute Fire Resistance

For projects with lower fire-resistance requirements.

Actual fire-performance requirements and applicable certification standards vary by market and building application. Final specifications should be confirmed according to project requirements and destination-market regulations.

Applications

Suitable for a wide range of architectural applications, including:

• Commercial Buildings

• Apartment Buildings

• Office Buildings

• Hotels

• Hospitals

• Schools

• Public Buildings

• Mixed-Use Developments

• High-Rise Buildings

• Residential Developments

• Large Construction Projects

Customization Options

The steel fire-rated window system can be customized according to project drawings and technical specifications.

Available customization options include:

• Window dimensions

• Frame configuration

• Opening style

• Glass configuration

• Frame color

• Surface finish
