Why DSeal’s ASTM 6063 T6 Aluminium Outperforms Mild Steel Joints

Many low-cost expansion joint systems use mild steel frames. On the surface, the price looks attractive. But over 5–10 years, the true cost becomes clear.

Mild Steel Joint Problems:

• Rusts in moist environments (parking garages, rooftops, basements)
• Rust stains the adjacent flooring or wall finish
• Structural weakening over time
• Requires maintenance and repainting
• Eventual failure and costly replacement

DSeal ASTM 6063 T6 Aluminium Advantages:

• Naturally corrosion-resistant — no rust, no maintenance
• High strength-to-weight ratio
• Anodising or powder coating available for premium finishes
• Recyclable — environmentally responsible
• Lifetime typically 35+ years in normal conditions

Specify DSeal. Pay once. Last a lifetime.
