2025 New Arrival Front Welded Aluminum Spacer Bars for Double Glazing Units
2025 New Arrival Front Welded Aluminum Spacer Bars for Double Glazing Units is core component for premium insulating glass. Manufactured from 3003 alloy aluminum or high-purity aluminum using German waterless circulation technology and high-frequency welding, they deliver exceptional performance:
Superior Sealing: Integrated bending technology replaces traditional corner joints, eliminating leakage risks and extending seal lifespan by over 20%.
Durability: Anti-oxidation surface treatment resists corrosion in humid regions, with precise wall thickness (0.20–0.35 mm) ensuring high strength and bend resistance.
Smart Compatibility: Double-row micro-perforations maintain molecular sieve activity, preventing fogging while ensuring excellent adhesion to sealants.
Ideal for energy-saving building curtain walls and system doors/windows, they significantly enhance thermal insulation and longevity of insulating glass units.
