As you probably know, plywood is one of the most popular building materials out there, especially when it comes to all of the不同類型的工程木材. Plywood is used for a wide variety of purposes, but what many people wonder is how much weight it can actually support.
Yes, people do use plywood for some weight-bearing applications, but with that being said, is it ideal for this? Let’s get right to it and figure out how much weight plywood can support, how to calculate how much weight it can support, and more.
Is Plywood Ideal for Weight-Bearing Applications?
If you are wondering whether or not plywood is ideal for weight-bearing applications, what you need to know here is that it really does depend on the size, the thickness, and the type of plywood in question. There are manydifferent types of plywoodout there, dozens in fact, and they all have different strengths.
有了這一點，一個決定因素背後的數字是膠合板是否可以用於負重應用是多麼厚，因為它越厚，它可以容納。因此，膠合板，特別是厚度和高品質的膠合板，通常用作負載承載。
For instance, a good piece ofmarine-grade plywoodcan handle several hundred pounds per sheet.
Now, if you are building a house, what you do need to know is that of course, you aren’t going to use plywood to actually support the walls because it’s not strong enough to do that. However, plywood panels are used to connect the various studs to each other that form the frame of a home, thus assisting the studs in holding up the frame.
So, while plywood is not something that you would use purely for weight-bearing applications, it can certainly be a part of the equation.
What Determines How Strong Plywood is?
在上麵，我們確實提到了一件膠合板可以承受多少重量的數字，而是有多厚的是它是多麼厚，但隨著說的是，厚度不是這裏的唯一決定因素。這裏實際上有四種因素，它將確定特定膠合板可以持有多少重量，所以讓我們看看所有四個。
1. Thickness
就像那裏的任何材料都一樣，它越厚，而且越多，它就會越強。
Keep in mind that the thinnest piece of plywood that you can buy is usually 1/4-inch. However, this type of plywood can only hold up around 10 pounds, so that definitely isn’t ideal for weight-bearing purposes. Most pieces of plywood will range from 1/2- to 3/4-inch thickness, and these are ideal for structural purposes, such as for home building.
對於大多數情況而言，一塊3/4英寸厚的膠合板將足夠，但您可以隨時前往完整1英寸的厚度。
2. Number of Layers
The number of layers also makes a big difference, and of course, the more layers a piece of plywood has, the more strength it will have. Now, your lowest grades of plywood are going to have anywhere from three to four layers, and this is known as shop-grade plywood, which is only ideal for small purposes.
Next, you have those types of plywood that have anywhere from four to seven layers, and these can be used for things like flooring, cabinets, and other furniture-related purposes.
With that being said, if you want to go for something that can actually bear weight and be structurally sound, then you want to go for plywood that has seven layers or more. Keep in mind that each additional layer of plywood can add around five pounds per square foot of load capacity.
3. Species of Wood
What you also need to be aware of with plywood is the fact that thetype of woodused to make it does make a big difference. In other words, plywood made out of softwood is not going to be nearly as strong as that made out of hardwood.
4. Grain Direction
The other thing to pay attention to here is the direction of the grain. Plywood that has the grain or the direction of the wood running along the longest side is generally much stronger than the type of plywood that has the grain running along the shorter side.
Wood is the strongest in the direction of the grain, so this is important to consider.
How to Calculate How Much Weight Your Plywood Can Support
Quite honestly, if you are not a mathematical genius and you are not familiar with all of the technical terms related to plywood and engineering, then you are best off using a plywood load calculator found online.

What Is the Strongest Type of Plywood?
沒有疑問，最強烈的膠合板出現了海洋膠合板。海洋膠合板可以容易地每張持有幾磅100磅。
概括
Now that you know exactly how to calculate the load-bearing capacity of the specific piece of plywood as well as the various factors that affect how much weight plywood can bear, you can now choose the right kind of plywood for your specific application.
