Which wood group is best for building a container requiring high strength and density?

Wood Group IV is considered the best choice for building a container that requires high strength and density. This group typically includes hardwoods known for their robust structural properties, making them well-suited for applications where durability and the ability to withstand significant loads are critical.

The hardwoods in this category are often denser and harder than those in the other wood groups, providing improved resistance to wear and tear. This makes them ideal for construction where the integrity of the container is paramount, such as for transporting heavy or sensitive materials.

When constructing containers, it is essential to select a wood type that not only offers strength but also maintains integrity over time, especially under varying environmental conditions. Thus, the density and strength of the woods classified in this group make them the preferred choice for such requirements.
