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.

For the saved grade-A teak branch, rainfall sixty, UV eight and coastal checked give zero weather stress and assumed seventy-five years. Hypothetical rainfall seventy adds one stress point, reducing rounded lifespan to seventy-four. Bars compare at six pixels per year. Lifespan clamps between forty and one hundred. These coefficients are illustrative source rules, not measured wood durability, verified material grade or a warranty. No physical furniture or climate data is inspected. At the default climate, oil loss rate is point sixty-two plus point three UV adjustment, point three rain adjustment and point three coastal, totaling one point five two percentage points yearly. Twenty-five years round to thirty-eight lost, leaving sixty-two. Structural loss rate point twenty-four times twenty-five gives six, leaving ninety-four. Bars compare retained scores at five pixels per point. These are separate synthetic metrics, not measured oil content, structural safety or biological degradation. Stored fourteen hundred base cost divided by seventy-five-year assumed lifespan rounds near eighteen dollars sixty-seven per year. At hypothetical forty-year clamp it is thirty-five. Bars compare at fifteen pixels per annual dollar. Maintenance selection changes color labels, which do not establish physical lifespan or treatment effectiveness. Native complete stable JSON report and reset preserve weathering logic and canvas. Actual prices, longevity, maintenance safety and furniture suitability remain unverified.
