Aluminum Screen Frame Profile For Doors

 

What is a Window&door Aluminium Profile

Our Window & Door Aluminium Profile is lightweight, high-strength, corrosion-resistant, and customizable, and is widely used for window and door frames, and other structural components in residential, commercial, and industrial projects.

 

Advantages
 
 
 

Structural Stability

The multi-cavity cross-section distributes stress and increases structural strength, maintaining stability under long-term operation and wind loads.

 
 

Excellent Airtightness and Watertightness

Multiple pre-set sealing grooves form a multi-layered sealing structure, preventing air infiltration and rainwater backflow.

 
 

High-Precision System Matching

Precision extrusion ensures consistent dimensions, enabling tight frame-to-sash fitting with minimal installation deviation.

 
 

Corrosion Resistance

The profile naturally forms an oxide protective layer, which, combined with anodizing or spraying processes, enhances weather resistance.

FAQ

 

Q: What sizes are available for aluminum profiles?

A: Aluminum profiles come in various standard sizes for structural and architectural purposes, ranging from small (10 × 2 mm) to large (200 × 20 mm). Common window and door profile dimensions include 20×20 mm, 30×30 mm, 40×40 mm, and 45×45 mm.

Q: What is the best aluminum profile for doors and windows?

A: Line 8 profiles with a 40 mm modular dimension are widely used due to versatility, compatibility with various systems, and ease of installation.

Q: What are the most common aluminum profiles?

A: Common types include 6061 aluminum channels, T-slot extrusions, 6063-T5 heat sinks, and 6061-T5 I-beams. Window and door systems typically use 6063-T5 aluminum for its strength, durability, and corrosion resistance.

Q: How thick is a high-quality aluminum door frame?

A: High-quality aluminum frames typically have a thickness of 1 mm or more. Low-quality frames often use mixed inferior materials, with a thickness of only 0.6–0.8 mm.

Q: What is an aluminum profile window?

A: Aluminum windows are produced using advanced extrusion technology, offering longer durability than vinyl frames and a wide variety of surface finishes and colors.

Q: How long do aluminum profiles last?

A: With proper surface treatment (anodizing, powder coating, or PVDF), aluminum profiles can last 20–30 years in normal residential and commercial conditions.

Q: Can aluminum profiles be customized?

A: Yes. Profiles can be customized in shape, size, surface finish, color, and thermal break design according to project requirements.

Q: Can aluminum profiles improve building energy efficiency?

A: Yes. Thermal break profiles prevent heat transfer between the interior and exterior, improving insulation and reducing energy consumption.

Q: What types of doors and windows can aluminum profiles be used for?

A: They are suitable for sliding doors, folding doors, casement windows, top-hung windows, and curtain wall window systems.

Q: Do aluminum profiles require maintenance?

A: Minimal maintenance is needed. Regular cleaning with water or mild solutions keeps the profiles looking new and maintains their performance.
