What is the table’s resistance to damage from prolonged exposure to de-icing salts?
The resistance of an outdoor table to prolonged de-icing salt exposure is fundamentally determined by its core material and protective finishes. De-icing salts, primarily composed of chlorides, accelerate corrosion through electrochemical reactions and physical abrasion. High-quality aluminum tables, especially those with a powder-coated finish, offer superior resistance. The coating acts as a robust barrier, preventing salt from reaching the metal substrate. Cast concrete and certain dense, composite plastics also demonstrate high inherent resistance, as they are non-porous and chemically inert.
For steel tables, galvanization or stainless steel (Grade 304 or preferably 316 for coastal areas) is critical. The protective zinc layer in galvanized steel sacrificially corrodes before the base metal. Regular maintenance, including prompt rinsing to remove salt residue and immediate attention to any finish chips or scratches, is essential for all materials. Ultimately, a table's longevity in salt-prone environments depends on selecting engineered, weather-resistant materials and committing to proactive seasonal care to mitigate the corrosive cycle initiated by de-icing agents.
