Redwood | The Wood Database - Lumber Identification (Softwood).Elastic modulus: 1,220,000 lbf/in<sup>2</sup> (8.41 GPa). Crushing Strength: 5,690 lbf/in<sup>2</sup> . Comments: Capable of attaining heights of nearly 400 feet, redwood (Sequoia sempervirens) is the world's tallest tree species. It grows in a very limited . second-growth lumber. On the whole, old-growth lumber tends to be slightly heavier (29 lbs/ft<sup>3</sup> versus 26), harder (480 lbf Janka hardness versus 420), and stronger (10,000 lbf/in<sup>2</sup> modulus of rupture versus 7,900) than younger second-growth lumber.

Redwood | NZ Wood.redwood makes an excellent substitute for cedar exterior cladding provided sapwood is excluded and hot-dipped galvanised, silicon-bronze, stainless steel or copper nails are used. In situations where corrosion of fastenings is a problem e.g., areas exposed to salt laden winds, particularly on buildings where the head of the nail is left exposed, annular grooved silicon-bronze or stainless steel nails are a better option. It makes excellent outdoor furniture provided it is used in chunky .
