How does eucalyptus wood’s hardness compare to teak when used for high-traffic outdoor trash cans?

When selecting materials for high-traffic outdoor trash cans, hardness is a critical factor determining durability and longevity. Eucalyptus wood, with a Janka hardness rating ranging between 1,125 and 1,450 pounds-force (lbf), demonstrates remarkable density and resistance to indentation. This makes it exceptionally capable of withstanding the bumps, scrapes, and heavy use typical in public spaces. Its tight grain structure further enhances its ability to resist dents and wear over time.

In comparison, teak wood, a long-revered standard for outdoor applications, possesses a slightly lower Janka hardness rating, typically between 1,000 and 1,155 lbf. While still a very durable and hard wood, it is technically slightly softer than many varieties of eucalyptus. Teak's legendary status comes not solely from its hardness but from its unparalleled natural oil content, which provides exceptional resistance to moisture, rot, and insects.

For the specific application of high-traffic trash cans, both woods perform admirably. Eucalyptus's higher hardness rating suggests it may better resist physical abrasions and surface dents from impacts. However, teak's superior natural oils offer a broader defense against environmental decay. The choice often comes down to prioritizing brute force resistance (eucalyptus) versus all-around weatherproof durability (teak), with cost-benefit analysis playing a significant role as eucalyptus often presents a more cost-effective option with similar structural performance.
