The Silent Threat: Salt Spray Corrosion
For architectural projects located within 5km of the coastline, standard metal hardware is under constant chemical attack. Salt-laden air and high humidity lead to "pitting corrosion" and mechanical seizure, rendering most retractable screens and bifold doors useless within 12-24 months.
BKH Marine-Grade Engineering
At BKH Systems, we have engineered a multi-layered defense system to ensure our hardware thrives where others fail. Our standards for coastal regions involve a rigorous selection of materials and surface treatments:
1. High-Micron Anodic Protection While industry standards often settle for 10μm, our BKH aluminum profiles for coastal projects undergo high-micron anodizing (up to 20μm-25μm). This creates an ultra-hard aluminum oxide layer that is virtually impenetrable by chloride ions.
2. SS316 & SS304 Components We don't just use "stainless steel"—we specify the grade.
SS316 Support: For critical load-bearing rollers and fasteners, we utilize SS316 (Marine Grade) to prevent tea-staining and structural rust.
Precision Bearings: Our sliding mechanisms are sealed to prevent salt crystal buildup inside the movement kernel.
3. Advanced Powder Coating (Qualicoat Standard)MBORMC® utilizes specialized powder coatings that meet international architectural standards. These coatings provide UV resistance and a secondary chemical barrier against the corrosive effects of sea spray.
Certified Reliability (Class 06)
As part of our Trademark No. 57344538 (Class 06) commitment, our coastal series hardware undergoes 1,000+ hours of Neutral Salt Spray (NSS) testing. This ensures that every component managed by the BKH technical hub can withstand the harshest maritime climates from Florida to the Gold Coast.
