In this regard, how much weight can a 2x6 joist hold?
Fine Homebuilding notes that 2-inch by 6-inch garage joists will support a weight of up to 50 pounds per square foot. If you overload your garage's ceiling joists, the ceiling may appear to sag from the strain. While your 2-inch by 6-inch joists can collapse from too much weight, such a scenario is uncommon.
Similarly, how much weight can a 2x4 joist support? If there is no strong wind, a 2x4 measuring at least 8 feet can support at least 1,000 pounds vertically. Such calculations would hold if, for instance, the load is square.
Besides, how much weight can floor joists support?
For example, a properly designed office floor can support 50 pounds per square foot. This may seem light, but this is 50 pounds over each and every square foot of floor space. It does not mean that a 300 lb.
What is stronger 4x6 or 2 2x6?
A 4x6 joist is theoretically stronger than a doubled 2x6 joist because it's 1/2" thicker, but the actual strength depends upon the knots and other inherent weaknesses of any particular piece of lumber (#2 lumber can have some nasty spike knots or large not-so-tight round knots or wane).
