The size of lumber you use for deck joists varies depending on the size and span of your deck. Generally speaking, it is recommended to use lumber that is at least a 2×8 for joists that span 8 feet or less, and a 2×10 for joists that span longer distances.
The wider the joist, the less time it will take for the deck to wobble or flex. The size of the joist you choose should also be based on the amount of weight that will be on the deck. If you plan to use heavy materials, such as composite wood for your deck surface, or if you plan to use the deck for supports, such as for a hot tub, you may need to use stronger and wider joists, such as a 2×12.
To determine the best option for your deck, it is important to consider the size and weight of the materials, as well as the span of the joists.
What kind of wood do you use to frame a deck?
When it comes to framing a deck, the most common type of wood used is pressure-treated lumber. Pressure-treated lumber has been treated with preservatives that make it highly resistant to rot and insects, making it an ideal material for use in outdoor projects like decks.
This type of lumber is available in different sizes, grades, and prices, so it is important to understand the differences between them when making a decision. In addition, micropro-treated lumber, also commonly used for deck framing, is created using a new technology that results in even stronger, more reliable wood for a longer lifespan.
For projects in areas of high humidity or moisture, Shou Sugi Ban lumber is a great option. This type of lumber is charred, making the wood resistant to rot, insects, and mold. Finally, depending on the location and size of the deck, engineered wood like LVL, I-joists, glulam beams, or rim board can be a great option for deck framing due to their strength, size, and ability to span longer distances.
What size timber do I need to build a deck frame?
The size of timber you need to build a deck frame will depend on the design of the deck, the load it needs to support, and the location of the build. Generally, for a standard framed deck, the most common size timber to use is 90x35mm (also known as H3 treated pine).
The 90mm length provides the necessary strength for decking support and the 35mm width provides a good surface area for joists, bearers, and other supporting structural members. Additional structural members may need to be larger than 90x35mm depending on the size and design of the deck, with sizes such as 140x45mm and 190x45mm being commonly used for larger decks.
Make sure to consult with your local building authorities before choosing the timber size and type, as different areas have different regulations.
What is the size wood for decking?
The size of wood used for decking depends on a variety of factors, such as the project you are undertaking and the type of wood you choose to use. Generally speaking, the most commonly used decking lumber is 5/4″ (1-1/8”) thick and comes in standard lengths of 8′ and 10′.
Other popular decking board sizes include 2×4, 2×6, and 2×8. It’s important to buy wood that has been pressure-treated against fungal decay, as this will protect your decking in the long term. When it comes to selecting the right decking size for your project, it is important to keep in mind the size of your joists, the steps in your deck, and the amount of weight that the deck will be able to bear.
Additionally, the span between joists should not exceed 16″, so you may need to double joist the decking in order to span greater distances. As always, it is best to consult an experienced contractor to ensure your project is done correctly.
Should I use 2×6 or 2×8 for deck joists?
The answer to this question depends largely on the size and weight of your deck as well as the local building codes in your area. With that said, there are a few key differences between 2×6 and 2×8 joists that should be taken into consideration when building a deck.
2×6 joists are 1 1/2″ thick and 6″ deep, while 2×8 joists are 1 1/2″ thick and 8″ deep. The extra two inches of depth on the 2×8 joists offers more support and stability, especially when wider spans are necessary.
If your deck plans call for wide spans or extra weight, then 2×8 may be the best choice.
Another advantage of 2×8 joists is that they can be placed farther apart than 2×6 joists, which can significantly reduce the amount of material used in the construction of the deck. This can add up to significant savings over time, especially if you are covering a large area.
However, this can also mean there is less stability between joists for heavier loads.
In terms of local building codes, make sure to check with your local municipality to make sure you are using the proper materials. Depending on the size and weight of your deck as well as other factors like your area’s climate, you may be required to use a certain type or size of joist.
In conclusion, the choice between 2×6 and 2×8 joists comes down to the size and weight of your deck as well as the local building codes in your area. For most decks, 2×6 joists are sufficient, but in cases where extra support and stability is needed, 2×8 may be a better choice.
Be sure to check with your local municipality before making any decisions.
How thick do deck boards need to be?
The thickness of deck boards will depend on the type of material you’re using, as well as the purpose of the deck and where it’s being built. For example, structural deck boards – the boards used to make up the floor of a deck – typically need to be thicker and stronger than boards used for railing or decorative purposes.
Many types of decking material, such as pressure-treated lumber, composite boards, and hardwoods, come in several thicknesses. Generally, deck boards measure in length from 8 feet to 20 feet and come in thicknesses ranging from 5/4” (an inch and a quarter) to 2” (two inches).
For building a deck, it’s important to use the thickest boards possible for the sub-structure, including joists and beams. These should be set up with at least ⅝” thickness to ensure it can safely handle a high level of weight and foot traffic.
Boards used for deck flooring or railing can range from ¾” to 1” in thickness, depending on what’s being built. Keeping the boards of your decking project at least ¾” thick means that it should have a longer lifespan and increased strength and stability.
Can you use 4×2 for decking?
Yes, you can use 4×2 for decking. Depending on the type and weight of the decking material, 4×2 can be an effective and supportive option. Generally, 4×2 timber is stronger than just the 2×2 so it can support the load better when compared to 2x2s if the decking is made from wood or wood-based composite.
4×2 also can be used as joists and support beams to support a decking plinth and offer a more stable surface area. It’s advised to always check with a professional to determine the best decking material to use and the number of support beams needed for the specific decking installation.
How do you frame a wooden deck?
Framing a wooden deck involves several steps. First, you will need to prepare the area and lay out the design for the deck. This includes measuring and marking your space, taking into account any slopes in the ground and any obstacles like trees or power lines that could affect the design.
Once the design is set, it is time to set the support posts. This will involve digging the post holes, setting the posts and filling in the space around them with concrete. Once the posts are set, you will use joist hangers to attach the joists to the support posts.
The joists will form the frame of the deck, and they need to be secured at each corner to give the deck strength and stability. Once the frame is complete, it’s time to lay the deck boards. Make sure that each board is cut to the right size and securely fastened to the frame.
The last step is to finish the deck with the railing, stairs, benches and other features you may have decided on during the design phase. With all of these steps complete, your wooden deck frame should be ready to enjoy!.
How do you build a deck frame off the ground?
Building a deck frame off the ground is relatively simple and can be done in several steps.
First, you’ll want to take measurements to determine the size of the deck frame and then mark the measurements onto the ground or directly onto the ground. Next, you’ll need to make sure that the area is level, since decks sit on a flat surface.
This might require digging out a small area in order to create a level surface.
Once the surface is leveled, you can begin to build the deck frame. This will involve using your marked measurements to create the frame with the lumber of your choice. You’ll likely want to use treated lumber for the frame in order to withstand the elements and prevent rotting.
Additionally, proper deck framing usually requires the use of hurricane ties to ensure that the frame is safe and secure.
Finally, you’ll need to lay down a subfloor before you add the decking boards. The subfloor will provide an even surface upon which the decking boards can be laid. Once in place, you can begin adding the decking boards and securing them using fasteners.
Building a deck frame off the ground is a relatively straightforward project and can add significant functionality and beauty to your outdoor space. If you lack the time or know-how to do it yourself, you might consider hiring a professional to help.
How do I attach a deck frame to a post?
Attaching a deck frame to a post can be done using one of a few different methods depending on the type of post and the type of frame you are using.
If you are using a wooden post and a metal frame, you will need to put a lag bolt through the metal frame and into the post. You will need to pre-drill the post in order to avoid splitting the wood, and you may need to use washers and nuts if the wood is hard.
For metal posts, you can use a metal hook or bracket to attach the frame to the post. You will need to pre-drill holes in the post and use screws and bolts to attach the bracket to the post and the frame to the bracket.
If you are using a wood post, you will need to use a pneumatic or an air-powered nail gun to attach the frame to the post. You will need to first use nails to attach the frame to the post, then you can use screws or bolts to secure it firmly in place.
For concrete posts, you can either use a hammer drill to pre-drill holes in the post and then use bolts to attach the frame to the post, or you can use an adhesive such as epoxy to glue the frame to the post.
Regardless of what type of post and frame you are using, you will need to make sure that the frame is securely attached to the post before moving on to the next step in your deck construction.
What’s the cheapest way to build a deck?
The cheapest way to build a deck is to do it yourself. Since you won’t have to pay a contractor, you can save a significant amount of money. Start by coming up with a design and a budget. Do some research to determine the materials you need and how much they will cost.
Consider buying recycled materials, building your own furniture, or bartering with a local store. If you already have some building materials, it may be possible to build the deck at a lower cost.
Next, plan out the steps of the project, such as gathering the materials, constructing the deck frame, and assembling the deck boards. Before beginning, it’s important to get proper permits, if necessary.
You may want to check with your local building department for any restrictions on the type of deck you can build.
During the building process, it’s important to take it slow and make sure the deck is level, square, and secured to your house. It’s also important to use galvanized screws or nails to fasten the decking and other components.
If you’re not sure how to do something, don’t hesitate to consult with family or friends who may have experience, or you can find helpful information online.
When you’re done building, it’s important to stain and seal your deck, if desired. Doing this yourself is much more cost effective than hiring someone to do it. Be sure to read and follow the instructions carefully and wear proper safety gear when working with chemicals.
By following these tips, you can build a deck yourself and save money in the process.
How much can you save by building your own deck?
The amount you can save when building your own deck can vary depending on the size and complexity of the project and the cost of materials. Generally speaking, do-it-yourself deck projects range from about $500 for a basic ground-level deck up to several thousand dollars for a complex multi-level deck.
Depending on the quality of materials and the cost of labor in your area, you may be able to save 30-50% by doing the build yourself.
