Lumber exists in two types, namely softwood and hardwood.

Are there any support beams under the 20’ span? Therefore, placing too much load on a 2x6 softwood beam may not be an advisable plan. Material is generally supplied in even lengths only, multiples of 2', from 8' to 20'.

For instance, the Southern Pine is considered to be much stronger compared to the spruce species. For an expansion of the corresponding factors, read through for better understanding of how much is a 2x6 load capacity. It would also answer the question of how much weight can a 2x6 support vertically and horizontally.

Boards will run length-wise in each section. eval(ez_write_tag([[970,90],'mysundaytools_com-large-mobile-banner-1','ezslot_5',174,'0','0']));​Generally, each wood species exists differently when it comes to strength. 1x4 or 1x6 for 16" joist spacing; These qualities translate into softwood beams being lighter, and care must be exercised to ensure they pass the test of time.

The depth of each structural member will also be a key player here.

will provide more support, strength, and improved floor assembly compared to 2x4 of the same grade and species. Decking Calculator to calculate BF, SF, and LF amount of 1x4, 5/4x4, 2x4, 1x6, 5/4x6 or 2x6 decking material needed to cover deck area.

4" wide material is calculated at 3-5/8" and 6" at 5-5/8" net coverage. Width:

The duration of a load mostly affects the strength rating (Fb) of lumber while the stiffness value (E) is not affected by the load.

The type of load in question will also determine how much weight a 2x6 can hold on edge. Softwood lumber is also fast in absorbing and losing moisture compared to their hardwood counterparts.

We probably hit close to 1400 pounds. Default is 50 psf which you can change. The span of a 2x6 beam depends on several variables including the size, type, and species of lumber as well as the load. The longer they are will mean an increased deck area that the joists can support. The strength of a beam varies based on various aspects.

As such, placing a 700 lbs. Material required for each section in SF, LF and BF will be listed. Calculations assume 1/8" spacing edge to edge between boards. Close to ground applications (36" or less) should use 4" width material. When all the factors are kept constant with the right weight calculations, it would mean that the lumber can support more weight both horizontally and vertically. It may be based on the weight and size of the load placed on it, for how long, among other factors.

This will, in return, translate into more support from the beam.


The examples of hardwood trees include walnut, mahogany, oak, and maple.

I am no engineer but if I were you I would do double PT 2×12 with 3/4″ PT plywood sandwiched in between and glued and screwed.

2x4 or 2x6 for heavy duty or commercial applications. As such, the question of how much weight can a 2x6 support horizontally may have varied answers. engine ?

The trees are characterized by a hard texture and ability to bear heavy loads. 5/4x4 or 5/4x6 for 24" joist spacing;

Air dried material is typically spaced the deck is 6′ wide and 5/4 treated decking.

The grade of the lumber is also an important factor to consider when determining a 2x6 load capacity.

Therefore, it becomes a clear indication that you may judge how much weight a 2x6 may support depending on how long you intend it to. can a home owner use a 2×6 to put more support on the floor joists for more support for and unlevel floor? I think I will do it with double 2×8’s with 1/2″ treated (because i have a lot of 1/2″ PT plywood) glued and screwed. I used double PT 2×12’s glued and screwed on 48″ centers. For example, 2x6 joists that are spaced 24-inches o.c. I only need around 1,000 pounds capacity but I am confident it will hold much more. Choose material size: at 1/8" edge to edge. It then determines the total load from each tributary area based on the design load of your deck. For example, a 2x4 lumber may hold a 4-cylinder engine comfortably but may not hold a bigger one.

We run our ATV’s plus a small trailer with about 200-250 pounds of gravel.

All Rights Reserved. The reason they are categorized as softwood is that one can bend them with the slightest effort.

I want to build a bridge 20ft long that will take a load of 1500lbs.What size lumber will I need. If a certain species has a higher grade than another species, it will also have a better strength provision.

Good luck on your project. Its strength rating will be higher, and so will its stiffness value.

We'll assume you're ok with this, but you can opt-out if you wish. Hardwood, on the other hand, comprises of deciduous trees whose leaves fall during cold months. On the other end, a 2x6 can support a V8 engine of between 600 – 700 lbs. engine on the latter, for example, may limit its lifespan while the Southern Pine will support it fully. The length of the joists also has an impact on the weight it can support. (on edge of course). I am currently planning a 6′ bridge 12 long.

No spacing is required between ends of boards.
Best Flooring For Concrete Slab Foundation. Span Calculator for Wood Joists and Rafters also available for the Android OS. About 10 years ago I built a 24′ clear span bridge.

How much weight can a 2x6 hold on edge based on load type? Install all materials in accordance with manufacturer's instructions. How long can a 2×6 which is supported on each end be and still support a 600-700 lb.

Because you would require much beefier lumber!There is zero chance I would risk 2×6 or 8 for a 20’ span without a support beam in the middle.
