What is a joist stringer?
The stringer is the piece of lumber bolted to the house upon which the joists are fixed on or to. The spacing between the bolts depends on the size of the stringer and the span of the joists which are fixed on or to it.
How far apart should floor stringers be?
In most homes, the common standard is 16 inches on-center. This means from the center of one joist to the center of the next joist there is a measurement of 16 inches. This spacing can be as much as 24 inches apart if you are using a higher grade (therefore stronger) lumber or if your span is very short.
What is a Joyce in building?
A joist is a horizontal member that generally runs across a building and is supported by a beam.
Are stringer hangers required?
Stringer hangers look like joist hangers and function in the same way. Most local code authorities require the use of stringer hangers, and using them makes installation easier.

Are there different grades of lumber?
There are four possible hardwood lumber grades. Grade is determined by the amount of clear surface area a particular board has on its poorest looking side (with hardwoods one side will look better than the other). A higher grade board is long and wide with a large percentage of its area defect-free.
What kind of stringers do you need for a raised floor?
Quick Overview. Stringers are steel or aluminum rods that form a basic grid which provides lateral stability for raised floors. Please note that all raised floor systems (i.e. woodcore, steel) require different stringers. If you are installing a new floor, stringers and understructure are included in our kits.
Where do the stringers go on a subfloor?
The frame for a subfloor is similar to a large wooden square. The joists at the edges are the header and stringer joists. They run parallel to one of the house’s exterior walls. The stinger joists are nailed on end into the header joist, with the header covering the butt of the joists.
How big is the stringer on a woodcore floor?
In woodcore systems, panels sit on top of the stringers, and in most steel systems, the panels nest inside the grid. Depending on the design, a gasket is typically included with the stringer that is factory or field-installed. Stringers are usually 2′ or 4′ in length, and can be snapped into place or fastened from the top with a screw.
What’s the difference between stair stringers and floor stringers?
Stringers used in flooring are not the same as stringers used in stairs. Although they share a name and both offer support to a structure, stair stringers have a distinctive difference. They are perpendicular to the stairs. The header piece at the top of the stairs is parallel to the stairs.
