What factors affect the weight of plywood?
A few factors impact the weight of plywood. The precise thickness of the panel is a major factor in the weight. Not all plywood is the nominal thickness after drying. Learn more about the actual thickness of plywood . In addition to thickness, the type of plywood is a major factor in how much it weighs. Different species of woods have varying ...
Which is denser, plywood or MDF?
Different grades of plywood may also have more or fewer voids than others, which might slightly impact the weight. A panel made up mostly of particles and glue (MDF) will be much denser than plywood with many voids and less glue.
Why is hardwood lumber heavier than softwood?
For example, hardwood lumber weighs more than softwood lumber due to higher densities. Calculate the weight of different species of lumber using our lumber weight calculator . Different types of plywood also have varying amounts of glues and resins, which affect the weight significantly.
How much does 3/4 plywood weigh?
Engineers have rounded-off weight calculations for plywood to square foot calculations, and have decided that, for engineering purposes, a generic square foot of 3/4-inch-thick hardwood plywood weighs 2.3 pounds. A 4-by-8 sheet of plywood equals 32 square feet, so 32 times 2.3, is just over 70 pounds per sheet.
How many species of wood are used to make plywood?
More than 70 species of wood are used to make plywood. The varied adhesives used in the process weigh more than the wood itself. The combined inconsistency of materials makes plywood weight calculations differ to some degree. But there are generic formulas, and when used as guidelines only, can be used to calculate plywood weight.
What is the lightest plywood?
Softwood varieties will typically weigh less than the hardwood varieties, but the lightest plywood of them all is typically pine.
Is plywood a sheet?
Other Sheet Materials. Plywood might not actually be plywood, but actually an engineered product. Lots of cabinets and furniture makers rely on a particle board or MDF -- medium-density-fiberboard -- and it's heavier than plywood. With a hardwood veneer, MDF has a dense particle board core, and looks just like ordinary plywood.
Is MDF plywood or plywood?
With a hardwood veneer, MDF has a dense particle board core, and looks just like ordinary plywood. It's much heavier, tipping the scales at between 90 and 100 pounds for a single sheet. If you're not sure if it's MDF or not, examine the side. If you see layers it's plywood.
Is fir plywood heavier than maple?
Hardwood is more dense than softwood, so a sheet of fir plywood will typically weigh less than a sheet of maple. If you're not sure what you're dealing with, it's always better to estimate on the heavy side, especially when loading multiple pieces on a pickup truck, for example, or estimating the weight for a floor.
Is 3/4 inch plywood thinner than 3/4 inch?
Even though you might purchase plywood stated as 3/4-inch-thick, it's likely thinner. Plywood is sized nominally, which is a generic reference to it's thickness. For example, a 3/4-inch piece of plywood may only measure 13/16 inch actual thickness, and therefore weigh slightly less than it's nominal measurement of 3/4 inch.
How thick is plywood?
The most common plywoods are 1/2-3/4” thick. These sizes are for anything from quick DIY projects to home structural uses. The thickest pieces of plywood are only 1” thick. Slim in the grand scheme of things, this plywood is strong enough to be used in industrial building projects.
Why does thickness matter in plywood?
The reason why thickness matters so much with plywood is due to the layers. For that reason, the number of layers are specified in a plywood’s name by ‘Ply’. 3-ply means 3 layers, 4-ply is 4 layers, etc. Being made from thin layers glued together, more layers greatly increases the strength of a plywood. More layers increases Plywood’s strength.
How many layers of plywood is good for a kitchen?
Going up to 4-7 layers means the plywood can be used for furniture – like kitchen cabinets, or even flooring. Anything above 7 layers is incredibly strong, but starts to limit functionality.
What is the grain direction of plywood?
Any piece of plywood that you buy should have the grain of the wood (the lines that run through the timber) running down it’s longest length. The grain of the wood should run along the longest length of the plywood.
What is the strength axis?
The strength axis is parallel to the grain. This simply means that the grain of the wood runs across the span which is taking the load. No load factors applied (i.e. construction imperfections, material imperfections, potential snow-load, or weakening with time are all not taken into account).
What is the density of structural plywood?
Structural plywood requires a very higher compression ratio compared with non-structural plywood. Non-structural eucalyptus plywood density is 580 kgs/m3. Structural eucalyptus plywood density can be as high as 600 kgs/m3.
How much does birch plywood weigh?
Birch Plywood weigh 650-700 kgs per cubic meter. Plywood with the lightest weight is made with a Benuang core. Its scientific name is Octomeles sumatrana. This is an Indonesian wood species. It also grows in Papua New Guinea with a local name Erima.
Is WBP phenolic glue heavier than normal urea glue?
WBP Phenolic glue is heavier than normal urea glue. For example, poplar plywood with urea glue density is 520 kgs/m3. Poplar plywood with phenolic glue density is 530 kgs/m3. Some manufacturers spread more glue on the veneers to increase strength. This practice will also increase the weight of plywood sheets.
Plywood and OSB Weight Factors
The weight of plywood and OSB depends partly on the amount and the type of the adhesives, primers, and sealants used to make it. Different types of plywood will use different amounts of these substances, and they are very heavy relative to wood.
What is Plywood Made of?
Plywood is composed of approximately 92% – 97% wood, with the remainder made up by primers, sealants, and adhesives such as phenol formaldehyde resin.
Weights of Different Types of Plywood
APA Plywood Standard: The Engineered Wood Association (formerly the American Plywood Association) provides standard notional plywood weights for use in determining expected dead loads when performing structural engineering calculations.
Ask the Lumber Company!
The values given in the following tables are meant to provide a general idea of typical engineered wood panel weights, and should not be used if precise values are needed for critical engineering calculations.
About Our Plywood Weight Charts
The following tables provide typical weights (dead load, self-weight) for plywood, OSB, and other engineered wood panels.
What is the importance of knowing the weight of plywood?
After you buy plywood, you’ll need to move it to where it is required, and it will also be moved around the area of application depending on how it will be used. You need to know both the maximum load capacity of your method of transport and the weight of the plywood.
Main factors influencing the weight of plywood
Two main types of trees are cut into logs for plywood sheet production: hardwood and softwood trees. Hardwood trees are heavier than softwood trees. For example, plywood made from mahogany or oak is heavier than plywood made from birch. Even when dried and the moisture tubes are empty, the denser wood has more air tubes, increasing weight.
Calculating the weight of a single sheet of plywood
To know the weight of an entire board of plywood, you’ll need to calculate the weight of one single sheet. Measuring the whole plywood board is difficult and almost impossible if you have numerous boards of plywood. Measuring the weight of plywood by starting with calculating the weight of a single sheet also provides a more estimated figure.
Calculating the weight of one sheet of plywood
To get the weight of one single sheet of plywood thicker or thinner than the ones listed, you can use the cross-multiplication method if both plywood boards are of the same size.
Final thoughts
If you are going to use plywood in any form of construction, whether large or small, you need to know the weight. For smaller projects such as coffee tables and bookshelves, knowing the weight may not be necessary. You can test the plywood by yourself and see if it will hold but ensure you check for any damages that may be a sign of weakness.
How much weight can plywood support?
But just how strong is plywood? How much weight can plywood actually support? The thickness is the most important part. A 12-by-36-inch piece of plywood that is ¼-inch thick will only support about 5 pounds before it starts to bend. But a 12-by-36-inch piece of ¾-inch plywood can support 50 pounds easily.
How to tell the strength of plywood?
A good way to determine the strength of the plywood being used is to look at the number of layers associate with that plywood. The cool thing is that you can count each of the layers by focusing on the edge of any of the pieces of plywood that you use.
Why is glue used on plywood?
The glue keeps the plywood from taking on moisture. Moisture is what can cause the layers within plywood to separate, weakening the plywood over time. Should the manufacturer use inferior glue on its softwood plywood, then it won’t be as strong as the hardwood plywood.
Why do they use exterior glue on plywood?
To overcome that weakness, some manufacturers will make use of exterior glue to give adhesion to the layers. The exterior glue, when used on softwood plywood, can even make that softwood plywood stronger than its hardwood counterpart with some time. The glue keeps the plywood from taking on moisture.
How many layers of plywood is moderate strength?
Moderate strength plywood will have anywhere between 4 and 7 layers to it. When it comes to moderate strength plywood, you can also use it for nearly any project that you can think of outside of industrial projects. The strongest plywood that you can find has more than 7 layers to it.
Why is plywood so strong?
The reason that it is so strong is because of how it is constructed. There are several layers of varying materials that have been bonded together under high pressures. These layers are then glued on top of one another. Plywood also uses alternating grain patterns.
What is the thickness of plywood?
The thicker that the plywood is, the stronger that it will be. That is why one of the most commonly used thicknesses for plywood is ¾-inch. When it comes to heavy-duty construction projects, 1-inch-thick plywood is typically the plywood of choice. There are also pieces that have tongue and groove patterns.
