Trusses made from metals such as steel will last far longer than any type of wood. Because they are made from non-organic materials, metal trusses are not susceptible to pests such as mold, termites, other insects, or natural decay. If properly treated, they are not susceptible to moisture damage, even if left out in full exposure to the elements.
But there’s more. Metal isn’t just durable, it’s also incredibly strong.
For example, steel can bear heavy loads of snow without buckling. That makes it an excellent choice for areas that get a lot of snowfall or other extreme weather such as hurricanes, ice storms, and heavy winds.
As well as being resistant to decay, rot, and moisture damage, steel trusses are basically impervious to fire too. That is not to say that your building will never burn if it has steel trusses, but at the very least a building with metal components takes longer to collapse, giving you more time to evacuate.
Their fire resistance makes metal trusses especially desirable in areas with frequent storms, wildfires, or seismic activity, all of which increase the chances of a structure fire.
If you are stacking hay or other products in a barn you want to be able to stack it right up to the ceiling so you don’t waste any space. And if you are driving tall machinery around in a building, you want plenty of headspace to avoid unintended accidents.
The design of metal trusses allows for more headspace in your building so you can make use of all the space you can. Alternatively, wooden trusses tend to allow for less headspace which wastes space and makes it hard to maneuver large machinery inside.
Wood has a beautiful, natural look. But in a large building, metal trusses give an open, airy look that is sleek, modern, and attractive. That is partly because metal trusses are more streamlined than most wooden trusses, and partly because you can space your metal trusses further apart since they are stronger than wood. This lends itself to a more spacious aesthetic.
In other words:
Metal trusses may be the way to go for aesthetics as well as durability if you are constructing a building that should be attractive inside.
It’s a win-win!
