When it comes to selecting the strongest type of wood for a project, it's crucial to understand that "strongest" can mean different things. It could refer to the wood's hardness, durability, or resistance to decay. Nevertheless, let's delve into some of the most robust woods for your consideration.
Hardness is often the first attribute that comes to mind when discussing wood strength. This refers to the wood's resistance to denting or gouging. The Janka hardness test is a standard measure for this, rating woods on a scale up to 4,000 pounds of force.
Hardest Woods
The hardest woods are typically dense, heavy, and excellent for flooring. They're highly resistant to scratching and wear, making them a popular choice for high-traffic areas.
Lignum Vitae
Lignum Vitae, or 'wood of life,' is one of the hardest woods available, rating at a staggering 4,500 lbf (pounds-force) on the Janka hardness scale. It's exceptionally dense, heavy, and resistant to decay. Traditionally, it was used for dilating wood parts in yachts due to its exceptional resistance to corrosion and UV damage.
However, it's important to note that Lignum Vitae is on the IUCN Red List of Threatened Species, making it challenging to obtain and ethically contentious to use in new projects.
African Blackwood
African Blackwood (also known as Grenadil) is another exceptionally hard wood, rating around 2,550 lbf on the Janka hardness scale. It's heavy, strong, and highly resistant to rot. Traditionally used for carvings and turnery, it's also prized for musical instruments due to its rich tone and outstanding projection.
Similar to Lignum Vitae, African Blackwood is also under threat due to overexploitation, so sustainably sourced options are recommended if you decide to use it.
Durable Woods
Durability isn't just about hardness; it's also about resistance to decay and pests. These woods are ideal for outdoor applications like decking, fencing, or furniture that will be exposed to the elements.
Teak
Teak is renowned for its durability and resistance to rot, insects, and UV damage. It's a close-grained wood with natural oils that make it impervious to decay. Traditionally, it was used for boat construction, and it's still prized for outdoor furniture and decking.
However, like the hardwoods mentioned earlier, Teak is also under threat due to overharvesting. Opt for certified, sustainably sourced Teak whenever possible.
Redwood
Redwood is another highly durable wood, naturally resistant to rot, decay, and insects. It's a softwood, so it's not as hard as the hardwoods mentioned above, but it's durable enough for many outdoor applications. Plus, it's a sustainable choice, as Redwood trees absorb more carbon dioxide than any other tree species.
When selecting the strongest type of wood for your project, ensure you're choosing a species that's fitted to your needs and ethically sourced. This way, you can use the best material for the job without compromising your environmental values.
