Supplier's note

1. Three Technical Breakthroughs:

   • Corrosion Resistance: The Pro Model’s zinc alloy coating exceeds industry standards (1200 hours vs. 800 hours), enabling safe use in coastal or industrial environments.
   • Adjustable Precision: The ±7mm adjustment range (Pro) accommodates uneven door frames, ensuring perfect alignment without re-cutting.
   • Weight Capacity: The Pro Model’s 300 kg load is 50% higher than base models, ideal for heavy fire-rated doors.

2. Optimal Version Selection:

   • Base Model: Best for standard residential doors (e.g., home entryways) where budget and ease of installation are priorities.
   • Advanced Model: Suited for commercial spaces (e.g., offices) requiring moderate load handling and aesthetic flexibility.
   • Pro Model: Designed for industrial use (e.g., factories, warehouses) where extreme durability, heavy loads, and precision adjustments are critical.

With stainless steel and zinc alloy construction, you can ensure long-lasting performance in corrosive environments. The Pro version’s triple-certified corrosion resistance paired with its 300 kg load capacity creates a failsafe solution for high-demand applications.
