Framing & StructuralQuestion 458 of 700
Fasteners and metal connectors that contact preservative (pressure) treated deck lumber must have what property to prevent premature failure?
a.Corrosion resistance, such as hot-dipped galvanized or stainless steel
b.The lowest possible cost regardless of coating
c.A bright, uncoated bare-steel finish
d.Aluminum contact directly against the treated wood
Explanation
Modern treatment chemicals are corrosive to unprotected steel, so fasteners and connectors must be corrosion resistant, typically hot-dipped galvanized or stainless. Choosing by cost alone, using bare steel, or placing aluminum in direct contact all accelerate corrosion and can fail the connection.
