Why do 2x4s have rounded edges?

2×4 have rounded edges as it’s very beneficial to the wood itself and those working with it. They reduce the number of injuries like unwanted splinters during the handling and manufacturing process and also ensure that the lumber stays looking its best all throughout until the customer sees it.

Why does framing lumber have rounded edges?

Framed walls with slightly out-of-square timbers would present a sharp edge when the face of the lumber is not perfectly square to the plane of the wall, so drywall could be damaged during installation. A rounded edge lessens drywall damage, even when studs are not perfectly square.

How do you get rid of rounded edges on a 2×4?

You don’t need a jointer to remove the rounded corners of a 2×4. You can do it with any tablesaw. Just make sure that you start with the straightest boards you can find. For the best results, crosscut the studs to the needed lengths before ripping the edges.

What is the chamfer on a 2×4?

A chamfer is a bevel, usually at 45 degrees on the side of a board. It’s main purpose is to soften the edge, both visually and more importantly to strengthen the wood corner against dings and donks.

Why does CLS have rounded corners?

CLS calls for kiln dried, regularised sizes, planed (though not very smooth) on four sides with radiused edges. The radiused edges are to ease handling – causing fewer injuries from sharp corners and splinters. The radiused edge apparently helps slow down the spread of fire in some situations too.

Why does CLS have round edges?

Its rounded corners and edges combined with the fact that it has small knots at it edges make it quite safe to handle and reduces the risk of accidents such as fire outbreak.

What is eased edge lumber?

Eased Edges (EE) Slightly rounded surfacing on pieces of lumber to remove sharp corners. Lumber 4 inches or less in thickness is frequently shipped with eased edges unless otherwise specified.

What is the difference between a bevel and a chamfer?

Unlike a beveled edge that joins one part with another, chamfers transition between two right-angle surfaces of the same part. Chamfers always sit at a 45-degree angle, unlike a bevel. The bevel may take more passes to make, with a typically larger area to cut than a chamfer, but this is subjective.

How do you make a 2×4 smoother?

You can also use a sanding block if you prefer. Again, sand with the grain of the wood for best results. Sand until all of the sanding scratches left by the rough-grit sandpaper are gone. By now, the wood will feel very smooth to the touch.

What is the best edge for a 2×4?

Smoother, rounded edges are more suited for bulk handling. When selecting multiple 2x4s from the lumber yard, the slightly rounded edges make it easier to pull individual pieces from the stack. Boards with rounded edges are also easier to slide into the back of a truck.

What are the advantages of a rounded edge on wood?

Rounded Edges Make Boards Easier to Handle Smoother, rounded edges are more suited for bulk handling. When selecting multiple 2x4s from the lumber yard, the slightly rounded edges make it easier to pull individual pieces from the stack. Boards with rounded edges are also easier to slide into the back of a truck.

Is there a big difference between 2x4s and modern lumber?

No getting around the price difference. If you could find an old house being torn apart, you might be able to take some 2×4’s from that. In doing the reno’s of our place (1939 house), we found the 2×4’s were straight and sharp edged. Total different beast than the modern lumber. The stuff framers use is rounded.

Can a round edge 2×4 catch fire?

A perfectly square edge has a sharp corner that will catch a flame faster than a rounded edge. When the lumber has rounded edges, this simulates the log, making it tougher for the flame to catch the wood’s fibers. Of course, a rounded edge 2×4 will still catch fire quite easily, so you must maintain all fire safety requirements.
