It is the second weakest grade in this scale: C14, C16, C18, С22, С24, С27, С30, С35 and С40.
Treated grade C16 refers to a classification of timber that has been pressure-treated for durability and is suitable for structural applications. C16 indicates that the timber has a specific strength rating, making it suitable for use in building projects like floor joists, wall studs, and roof trusses. The treatment process helps protect the wood from decay, insects, and other environmental factors, enhancing its longevity in construction.
Grade A classification for lumber refers to the highest quality of wood, typically characterized by minimal defects, a uniform appearance, and structural integrity. It is often used in applications where aesthetics and strength are paramount, such as furniture and cabinetry. Grade A lumber usually has a smooth surface and is free from knots, splits, or other imperfections, making it ideal for high-end construction and design projects.

You might be referring to 'pressure treated' lumber, or lumber that has been milled but not dry.
Pressure-treated lumber is not inherently incised lumber, but it can be. Incised lumber has small cuts or grooves made in the wood to enhance the penetration of preservatives during the pressure treatment process. While pressure-treated lumber often undergoes this incising to improve its durability and resistance to decay, not all pressure-treated lumber is incised; it depends on the specific treatment method used.
Treated grade C16 refers to a classification of timber that has been pressure-treated for durability and is suitable for structural applications. C16 indicates that the timber has a specific strength rating, making it suitable for use in building projects like floor joists, wall studs, and roof trusses. The treatment process helps protect the wood from decay, insects, and other environmental factors, enhancing its longevity in construction.
There are 16 carbon atoms in C16.
Treated lumber should be used in outdoor construction. There are different types of treated lumber, some are for above ground use and some are for below grade use.

The grade stamp on dimensional lumber typically includes information such as the grade of the wood (e.g., Select Structural, No. 1, No. 2), the species of the wood, the mill identification number, and the moisture content at the time of drying. It may also indicate compliance with specific standards or codes, such as those set by the American Lumber Standards Committee (ALSC) or the National Forest Products Association (NFPA). This stamp helps ensure the lumber meets certain performance and quality criteria for construction and building applications.
When selecting appearance grade lumber for a construction project, factors to consider include the wood's color, grain pattern, knots, and overall appearance. It is important to choose lumber that meets the desired aesthetic requirements while also considering the structural integrity and cost.
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.

When selecting appearance grade lumber for a woodworking project, consider factors such as the wood species, grain pattern, color consistency, knots, and defects. These factors can affect the overall look and quality of the finished project.

Yes. You will have to work around the ink stampings and knots, but the wood will take a stain.
There are a couple things that "graders" look for in a piece of lumber. One is the knot holes, if they are large this effects the grade. The other is bark no one wants a board that is all bark. So when you are looking for a strong piece of lumber you want one that has knot holes smaller than a half dollar coin and not all barked up the only bad effect that the bark has is it makes it hard to nail to.
