Aluminium Profile Types Guide: Which Profile for Which Project?
1 June 2026 // 6 min min read // ICS Technical Team Guide

Aluminium profiles are indispensable structural elements in the construction and industrial sector. Different aluminium profile types with various sections, alloys and surface treatments are available for every project's requirements. Here are the most common aluminium profile types and their applications:

1. Door and Window Profiles (Joinery Profiles)

Used in residential and commercial buildings, joinery profiles are divided into thermal-insulated and non-insulated. The C60 and Aldoks series are the most preferred aluminium profile systems for their durability and ease of installation. TW series thermal-insulated profiles provide energy savings through polyamide barriers.

2. Handrail and Railing Profiles

Aluminium handrail profiles used on balconies, stairs and terraces offer safety and aesthetics with square, round and custom section options. Anodised coating provides superior corrosion resistance.

3. Sill and Trim Profiles

Sill profiles that cover the junction points of door and window joinery with the wall contribute to heat and water insulation while providing a neat finish.

4. Industrial Profiles

Standard industrial profiles such as box profiles, L-angles, U-channels and T-profiles are used in machinery manufacturing, roof construction and solar energy systems. High-strength 6082 alloy is ideal for structural applications.

5. Custom Section Profiles

Custom aluminium profiles produced to project-specific sections, alloys and tolerances are suitable for serial production with mould investment. Widely used in automotive, rail systems and defence industries.

Tips for Choosing the Right Profile

  • **Location:** Indoor or outdoor?
  • **Load requirements:** Structural or decorative?
  • **Surface treatment:** Anodising or powder coating?
  • **Alloy:** 6060, 6063 or 6082?
