I encourage you being cautious about potential discoloring of the wood floor in direct proportion to the shape of the center rug piece over time. Discoloration will occur not as a result of the throw rug or center rug piece but as a result of sunlight beaming on the wooden floor in areas around the center rug piece. You see, underneath the center rug piece sunlight cannot get to the wood. So, the color of your wooden floor beneath the center rug piece would be lighter in color over time than the exposed areas. I recommend you use throw/scatter rugs instead of center piece or area rugs as these would be more readily removed, freshened or relocated to minimize a lengthy tenure in one location.
The manufactured joist, which is a relatively new product, is often manufactured from low cost materials in the shape of an I beam, similar to steel beams in larger buildings. What this means is that the joist is constructed with a thicker top and bottom edge, and generally interlocking aspenite vertically spanning between the two. These systems are very strong, often capable of spanning the entire width of the building.
Of all, the most commonly installed flooring system are framed floors. They consist of dimensioned lumber, bearing on exterior and interior load bearing walls or beams called "floor joists". Generally the floor joists are installed, spaced 16" apart. Installing rim and trimmer joists, to which the floor joists are nailed, finishes the perimeter. Bracing, usually in the form of bridging, but often installed as strapping, prevents the joists from turning in place. One other method used to prevent this type of turning is to glue the sub-flooring to the joists, as the sub-floor is placed.
Here is a word on prefinished product if they factor into your decision. If you come up short on your order, the next lot that you buy may not match your previous batch. This is especially a problem on the lower end price floors and import floors. Good luck trying to blend it in with your previous floor. So if you go this route, be extra accurate on your measurements. Right now the rage is lifetime warranties on flooring. We stop to think is that really even possible? First will that importer or manufacturer really be around a lifetime? A lot of products are made oversees; the warranty is only good if there is somebody still around for the life of the warranty.
