Which way is plywood the strongest?
parallel to grain
Wood is strongest in the direction parallel to grain. Because of this, the strength and stiffness properties of wood structural panels are greater in the direction parallel to the strength axis than perpendicular to it (see Figure 1).
What is the best plywood for shelves?
First and foremost, the wood you use for making bookshelves will impact the design as well as the cost of your project. ¾-inch plywood is considered the industry standard, thanks to it being strong yet inexpensive—especially when compared with some solid woods.

What is the best thickness for shelving?
Plywood Shelves Plywood for shelves should be 3/4 inch thick or thicker. Standard sheets of plywood come in 1/4-inch, 3/8-inch, 1/2-inch, 5/8-inch, and 3/4-inch thicknesses. Plywood panels over 3/4 inch in thickness are usually special order products.
Why is plywood not good?

Can you stand on half inch plywood?
As you can see, a 1/2″ plywood can support up to 35 pounds per square foot. But doubling that thickness to 1″ of plywood supports up to 164 pounds per square food. The increased thickness means plywood supports much more weight as it can redistribute the stress away from the center.
What is Blondewood plywood used for?
At this time, although blondewood plywood can technically be used for anything plywood can be used for, as long as it is not structural or exterior, it’s really only used for the making of fairly low-grade furniture.
Is there a difference between plywood vs OSB?
Plywood vs OSB: There is a difference. Find out which one to use on your next project. There is often a debate on which is better: plywood or oriented strand board (OSB). Both can be used in structural applications for roofs, walls and floors.
What size OSB is used for subfloor?
OSB came into use as a subfloor material in the 1970s. The type of OSB used for subfloors generally is made with tongue-and-groove edges (T & G). The standard subfloor for joists spaced up to 16 inches apart is 23/32-inch T & G sheets.
What is the difference between oriented strand board and plywood?
Whereas oriented strand board is made with short wood chips, plywood is made with long wood veneers, or in other words, long and thin strips of wood. Most plywood is made out of veneer strips that are made out of softwood, although higher grades of plywood may also be made out of hardwood.
