At 25 years outdoors, A-Grade Teak has developed its signature protective Silver Gray Patina. Despite receiving 60 inches of annual precipitation and coastal salt air, the heartwood retains 62% of its natural organic oils and rubber, maintaining an exceptional 94% structural integrity with an annual amortized cost of only $18.67/yr.
Data grounded in botanical tests of tropical Tectona grandis heartwood and municipal park bench field studies.
