How to Choose the Right Aluminum Profiles for Doors and Windows

Selecting the appropriate aluminum profiles for doors and windows is crucial for ensuring durability, energy efficiency, and aesthetic appeal. This guide will help you navigate the key factors in choosing the right aluminum extrusions for your project.

1. Understanding Aluminum Profile Specifications

Profile Series

Common series include 50, 55, 60, 65, 70, 80, 90, 108, and 120, where the number indicates the profile width in millimeters. Larger series generally offer greater structural strength.

Wall Thickness

According to national standards, the minimum wall thickness for main load-bearing sections should not be less than 1.4mm. For high-rise buildings, consider profiles with 1.6-2.0mm thickness.

Surface Treatments

• Anodizing: Creates an oxide layer for enhanced corrosion resistance

• Electrophoretic Coating: Provides smooth surfaces with good weather resistance

• Powder Coating: Offers diverse color options and strong corrosion protection

• Fluorocarbon Coating: Premium treatment with exceptional weather resistance

2. Selection Based on Environmental Conditions

Climate Considerations

• Coastal areas: Opt for corrosion-resistant profiles with fluorocarbon coating

• Cold northern regions: Consider thermal break aluminum profiles for better insulation

• Rainy southern regions: Select profiles with excellent drainage design

Building Types

• High-rise buildings: Choose larger series with high wind pressure resistance

• Residential buildings: 60-80 series profiles typically suffice

• Commercial buildings: Consider 90+ series for larger glass panels and aesthetic requirements

3. Performance Considerations

Thermal Performance

• Standard aluminum profiles conduct heat rapidly

• Thermal break profiles separate interior and exterior aluminum with insulating bars

• Optimal insulating bar width typically ranges 12-30mm

Acoustic Performance

• Double-glazed units with quality seals enhance sound insulation

• Multi-chamber profile designs improve noise reduction

Air and Water Tightness

• Examine seal groove designs

• Check precision at profile joints

4. Brand Selection and Quality Assessment

Reputable Brands

• Domestic: Jianmei, Fenglu, Yalum, Xingfa

• International: Schüco, YKK, Hydro

Quality Verification Methods

• Surface inspection: High-quality profiles have smooth, bubble-free surfaces

• Thickness measurement: Verify with calipers

• Flexibility test: Quality profiles bend slightly but return to shape

• Markings check: Look for clear manufacturer identification

5. Matching Components

Hardware

Select high-quality hinges, tracks, and locks compatible with your profiles

Sealing Materials

EPDM seals outperform PVC alternatives in durability

Glass Options

Choose from standard, tempered, or insulated glass based on requirements

6. Budget and Value Considerations

• Standard aluminum profiles offer lower upfront costs

• Thermal break profiles provide long-term energy savings

• Premium coatings increase initial cost but extend service life
