The Philippines faces a unique challenge due to its archipelago geography and high annual rainfall. Traditional low carbon steels often suffer from rapid oxidation and pitting corrosion in coastal cities like Manila and Cebu, leading to high maintenance costs for metallic structures.
Currently, there is a strategic shift toward using mild low alloy steel to improve structural integrity. The industry is moving away from simple painting solutions toward materials that possess inherent atmospheric corrosion resistance, reducing the need for repetitive surface treatments in humid zones.
The integration of corten steel sheets has become a trend in modern Filipino architecture and urban landscaping, blending industrial aesthetics with the functional necessity of a stable protective patina layer that thrives in tropical air.
