Softwood Timbers

Affordable Timber Decking

Softwood is less durable as an exterior decking timber compared to hard wood, coming from faster growing trees which are much easier to process, making it more economical initially. If you are looking for a decking option that will look good on final installation, but that won’t be required to take as much wear and tear, then softwood could work for you.

Choose the right timber for you and your project

Generally timber can be classified into either Hardwoods or Softwoods based on physical structure and characteristics. Hardwoods come from angiosperms, flowering trees like teak and usually grow slowly and softwoods come from gymnosperm, usually evergreen conifers like pine, which have a quicker growth cycle. Hardwoods should not be confused with the actual physical hardness of the timber. Please contact us if you have any questions.
