Curtain Wall Square Tube


1. What is a Curtain Wall Square Tube?

A Curtain Wall Square Tube is a structural metal profile, usually made from aluminum or steel, designed specifically for curtain wall frameworks. Unlike traditional structural beams, it is lightweight, corrosion-resistant, and provides an elegant rectangular profile that simplifies glass or panel installation.

Key attributes include:

  • High load-bearing capacity

  • Precision in dimensions for uniform façade alignment

  • Compatibility with various finishes (anodized, powder-coated, or painted)


2. Key Features and Specifications

Feature Description
Material Aluminum, Stainless Steel, Galvanized Steel
Cross-section Square, usually 20x20mm to 100x100mm
Wall Thickness 1.0mm – 4.0mm
Length Customizable up to 12 meters

These specifications allow curtain wall square tubes to deliver exceptional strength while maintaining a modern, minimalistic look.


3. Curtain Wall Square Tube vs. Round Tube: Which is Better?

When comparing square and round tubes for curtain walls, several points emerge:

  • Strength and Stability: Square tubes provide higher resistance to bending in specific directions, which is ideal for large glass panels.

  • Ease of Installation: Flat surfaces make it easier to attach brackets and panels compared to round tubes.

  • Aesthetic Appeal: Square tubes create a sharp, modern look favored in contemporary architecture.

  • Cost Efficiency: Depending on material and profile, square tubes may offer better material utilization.

Conclusion: For most modern curtain wall projects, square tubes outperform round tubes in both functionality and design compatibility.
