C16 timber is a common structural grade of softwood used in construction across Australia. When people look for strong, reliable, and affordable timber, C16 is one of the most widely used options. It means the timber has been strength-tested and meets a specific structural rating suitable for general building work. C16 timber is known for its good load-bearing capacity, making it ideal for joists, beams, studs, and other framing work. It’s also treated to resist issues like moisture or insects when required. Since it’s readily available through many timber wholesalers Sydney, builders and DIY users choose it for both residential and light commercial projects.
