40 Hour Property and Building Inspection Practice Test

True or False: Wood I beams have flanges made of laminated veneer lumber and webs made of plywood or OSB.

1. True

2. False

3. Only for plywood webs

4. Depends on manufacturer

The correct answer is: False

The assertion that Wood I beams have flanges made of laminated veneer lumber and webs made of plywood or OSB is not universally true. While some Wood I beams indeed feature flanges constructed of laminated veneer lumber (LVL) and may utilize plywood or oriented strand board (OSB) for their webs, this is not a standard characteristic for all Wood I beams. The materials used in the construction of Wood I beams can vary significantly depending on the manufacturer and specific product design. Some beams may use solid sawn wood, other engineered materials, or combinations thereof, as flanges and webs. This inherent variability means one cannot categorize all Wood I beams under a single set of materials without considering the manufacturer's specifications. Therefore, the correct answer reflects the fact that there is no singular definition for all Wood I beams, which can be made with a variety of material combinations based on different manufacturers' designs and preferences.
