Heavy-Duty Construction

Engineered for oversized door panels, these profiles feature wall thickness up to 3.0mm in load-bearing areas. Reinforced corner joints utilize internal steel reinforcements and mechanical connectors. Weight capacity reaches 150kg per sliding panel, supported by industrial-grade roller systems. The robust design withstands high-frequency usage in commercial and public building applications.

Enhanced Security Features

Multi-chamber profiles with internal steel reinforcements create pry-resistant barriers. Dedicated hardware channels accommodate up to 10-point locking systems. Security glazing options include laminated glass pockets and anti-lift track designs. All accessible fasteners require specialized tools for removal, providing additional deterrence against tampering.

Corrosion Resistance Package

Marine-grade anodizing with 25-micron thickness provides superior protection in coastal and high-humidity environments. All exposed surfaces receive chromate conversion coating before assembly. Drainage systems include diagonal water outlets that prevent clogging. Stainless steel components (screws, rollers, brackets) are standard throughout the system.
