As alternating heatwaves and torrential rains batter coastal regions, metal door components face accelerated corrosion. Leading manufacturer DuraShield has launched a polysilazane (PSZ) ceramic coating that transforms door frames into corrosion-resistant shields. Laboratory tests confirm the nano-coating withstands 800°C temperatures and boosts UV resistance by 500%, effectively combating salt spray damage. Deployed in luxury seaside residences in Hainan, the technology has reduced maintenance costs by 40%. Industry analysts project a 200% growth in PSZ-based protective solutions by 2027 amid worsening climate extremes.
