Hardwoods
Hardwoods – Properties, Uses & Special Features
Hardwoods come from deciduous trees that shed their leaves in autumn and regrow them in spring. They belong to the group of angiosperms and are characterized by a complex cellular structure with visible pores. Many hardwoods are dense, strong, and durable, making them ideal for high-quality furniture, toys, and interior design.
