Selection Guide for Color-coated Steel Sandwich Panel Aluminum Accessories: Professional Solutions for Accurately Matching Panels and Scenes (Ⅲ)

Ⅰ.Selection strategy of aluminum accessories according to usage scenarios

1. Industrial plant (conventional environment)

1) Core demand: economical and durable

2) Recommended configuration:

T-shaped aluminum (1.2mm, ordinary oxidation)

L-shaped groove (wall turning)

U-shaped groove (cornice edge)

2. Cold chain logistics (low temperature and high humidity)

1) Core demand: anti-condensation sealing

2) Recommended configuration:

Thermal bridge H-shaped groove (with PU insulation strip)

Triple seal L-shaped groove (strip + structural glue + airtight film)

Anti-condensation U-shaped groove (lined with insulation cotton)

3) Measured data:

The dew point temperature at the joint can be reduced by 5-8℃

3. Clean workshop (GMP environment)

1) Core demand: dust-free and easy to clean

2) Recommended configuration:

External arc aluminum (R50, antibacterial coating)

Seamless T-shaped aluminum (laser welding process)

Embedded L-shaped groove (flush with the board surface)

3) Cleanliness index:

Particle concentration at the joint ≤ISO Class 5 Standards

4. Coastal chemical industry (high corrosion)

1) Core requirements: Salt spray corrosion resistance

2) Recommended configuration:

316L stainless steel composite T-shaped aluminum

Fluorocarbon sprayed L-shaped groove (film thickness ≥ 40μm)

Cathode protection U-shaped groove (sacrificial anode design)

3) Anti-corrosion data:

Salt spray test > 3000 hours without corrosion
