But what about channel depth? Let me give you an example: P1000 is 12 ga and so is P5500.

When it comes to gauge (or thickness of steel) it goes without saying that the larger the gauge, the stronger the channel. Three other factors that affect Unistrut weight limits are gauge, channel depth, and channel configuration. Struts can hold more weight when it's a midspan load and less weight when the load is distributed asymmetrically. The position of your load also affects how much weight Unistrut can hold. If a strut is longer and doesn't have any bracings, it will hold less weight. The length of the channel and how the channel is supported will further alter weight limits. Channels with more holes and slots are a little weaker, so they don't hold as much weight as a solid Unistrut. Why is there so much variation in load limits? A lot of this simply boils down to the construction of the channel you're working with.

Meanwhile, in the P5500 series, maximum allowable load limits range from 330 pounds to 3,270 pounds. For example, in the popular P1000 line, maximum allowable load limits range from 170 pounds to 1,690 pounds. The general weight limit for Unistrut struts varies quite a lot.

To get the best results, you need to pick a Unistrut system that can handle the weight requirements of your next project. However, the wide variety of strut types and fittings means that it can take a little time to pick out a Unistrut product. As one of the most popular weldless metal framing systems, Unistrut products are incredibly useful for everything from ceiling supports to storage shelves.
