How do you extend a 4×4 deck post?
The best way to join two 4x4s to extend a post is with a half-lap. The simple cuts make it ideal for a beginner or pro to make, and it’s easier to do in limited space. Adding glue, plates, and bolts increases the lateral and twist resistance to form a very strong connection.
Can you notch 4×4 posts?

Quote from Youtube video: It has a very nice feature to lift this up and I made sure that this blade aligns with the line. That is my measurement for the notch. So this way when I run the circular saw right flat on the post.
Do deck posts have to be 6×6?
Deck posts must be a minimum of 4×4 according to the IRC but many jurisdictions require a 6×6 post as a standard. To avoid code violations, many deck builders choose the 6×6 even if the 4×4 is acceptable.
Can I use a 4×4 as a deck beam?
4×4 post will be fine. I have built many decks for new homes with them. 6×6 is more sturdy of course and will not twist as easy, but for structure purposes, 4×4 will be fine.
How do I lengthen a post?

Quote from Youtube video: I got a three-foot section traced around where I wanted it right smack dab in the middle got my four corners drilled those 5/8 inch 12 inches deep pounded by 5/8 inch rebar.
How do I extend my deck posts?
Doweling is another way to add shear strength. Post caps and metal plates are another way to lengthen posts. Add a wooden sleeve overlay to any of these methods, and the post should be strong enough to do its job.
What is notching a post?
Using a notched post and beam connection will lock the beam in place, secure it from rotating and resist wind uplift. Notching a post does not weaken the structural integrity of the wood support post because the load for the deck is transferred down through the post to the footings.
Does notching a beam weaken it?
Improperly sized or placed holes and notches weaken the joist, make it bouncy and saggy, and provide an easy place for it to crack and fail.
How do I attach a beam to a 4×4 post?
Quote from the video:
Quote from Youtube video: You can drive some through bolts all the way through the holes that are provided. That will give some additional support. You would just look at the load tables for the piece of hardware.
How much weight can a 4×4 post support vertically?
Properly supported at 16” centers, and it can support up to 4,000lbs. Used vertically as a post, an 8′ 4×4 can support about 6,000 PSI before buckling, and even more if correctly braced.
How high can a deck be with 4×4 posts?
eight feet
4, which limited the height of a 4×4 deck support post to eight feet, without any consideration for how much area of deck the post was supporting. The engineering behind post sizing is based on how much weight the post can support without starting to bend out of plane. The longer the post, the less it can support.
Is a 4×4 stronger than a 2×6?
Unless you are supporting it with columns every 4′, neither is strong enough to help much. A 2×6 has more vertical support than a 4×4. Is that correct? The 2×6 is stronger than the 4×4 when it comes to vertical loads.
Can you use a 4×4 to support floor joists?
A 4×4 would be strong in a vertical orientation (carrying loads on top of it), but not so strong in a horizontal orientation. You’d be better off with 2 sistered 2x6s, but likely if you’re carrying a floor you’ll want sistered 2×10 or 2×12.
Are two 2×4 stronger than one 4×4?
When used vertically, 4x4s are stronger than two 2x4s. However, if you need a horizontal surface, two 2x4s will be stronger than one 4×4. A 4×4 should not be used horizontally for anything structural. Always be sure that you’re using the proper size and strength of lumber.
Can you use 4×4 for studs?
An interior wall supporting just roof load is (usually) fine with 2×4 @ 24″, so 4×4 is fine too. An exterior wall has to support load plus wind and 2×4 @ 24″ is no good.
Can you make a 4×4 with 2×4?
Quote from the video:
Quote from Youtube video: I take two two by fours throw some glue down between them. And then I put three screws in on the middle one in each and then. And then I put nails put six nails two on the side with the screws.
Is a 2×4 stronger on its side?
Whether it’s a 2×4 or 2×6, dimensional lumber is strongest when it’s on edge. Why? A 2×4 has an extra 2 inches of thickness to add strength when used on its side. This is why dimensional lumber is on edge when used as headers for windows or as rafters in a shed.
What is a stud pack?
It is common practice in residential construction to use multiple pieces of 2x lumber connected together (sometimes referred to as “stud packs”) to build interior columns. One rule of thumb is to install enough studs to match the width of the beam above.
What are Builtup columns?
INTRODUCTION. Built-up columns are widely used in steel construction especially when the effective lengths are great and the compression forces light. They are composed of two or more parallel main components interconnected by lacing or batten plates (Figures 1 and 2).
What is meant by stub column?
A stub column is a type of column whose length is short and baseless which means do not have a foundation and footing as its rests on a beam or slab. It acts as a point load on the beam. A stub column does not fail by buckling because of its short length and It is constructed between one floor only.
