SIC 2452 applies to PREFABRICATED WOOD BUILDINGS AND COMPONENTS.
The prefabricated wood components industry includes many products, including premade panels and sections for chicken coops, farm buildings, geodesic domes, marinas, sauna rooms, hotel rooms, and decks.
NAICS 321992 applies to Prefabricated Wood Building Manufacturing.
By far the biggest segments of this industry are single-family homes, multifamily units, and institutional buildings, including hotels and motels, schools, hospitals, and prisons.
Pennsylvania was by far the leader in the production of three-dimensional assemblies; Wisconsin was the clear leader in production of buildings shipped in panel form.
The advantage of prefabricated wood building products is that they save builders money.
Total industry shipments in 2000 reached $3.58 billion, compared to $3.02 billion in 1997. Over the same time period, the total number of industry employees grew from 23,187 to 26,363.
About 709 companies participated in the prefabricated wood component industry in 1997. Because it is a localized industry by logistic necessity, most companies were small--only 249 had more than 20 employees.
Picture a typical wish list for any construction project these days, whether it is a backyard shed, a large factory, or perhaps a gracious and pleasing family home. The desire for lower construction costs and for an environmentally friendly final product would no doubt be high priorities on any such list. Although these two ideals may seem independent of each other, with a prefabricated steel building they merge to create the best of both worlds: The low-cost attributes of prefabricated steel are the very advantages that also enhance its green credentials. The relatively low price of prefabricated steel projects involves the material itself, the design and construction process, and the lifetime expenses of the building. Since steel is the most recycled material in use today, the extra expense associated with producing virgin materials such as wood lumber is not a factor. Steel is readily available and easy to recycle into end products. Furthermore, prefabricated steel building suppliers use CAD design processes to produce results engineered for optimal efficiency and strength with minimum materials. The pre-designed, prefabricated and, in many cases, pre-finished components are delivered to the construction site ready to assemble. This reduces onsite construction time and labor costs. After construction is complete, prefabricated steel buildings are low maintenance, rot and pest resistant, and generally come with extended warranties for workmanship and factory finishes. They are more energy efficient in terms of heat and cooling loss than comparable buildings, and this can be enhanced with options for increased insulation. Another available cost-efficient option is translucent skylights to increase natural light within. Finally, insurance premiums tend to be lower since prefabricated steel structures are more resistant to fire and to natural disasters such as earthquakes. It is easy to see that the cost-lowering advantages of prefabricated steel buildings are also its environmental advantages. The result is a lower carbon footprint before, during, and after construction. When completed with low-emission finishes and ample vents for optimal indoor air quality, these efficiently designed and manufactured buildings are strong environmental contenders. Indeed the final cost benefit to consider may be the green tax breaks that come with prefabricated steel buildings.
Mortise and tenons are used by woodworkers to join pieces of wood. the basic mortise and tenon comprises two components: the mortise hole and the tenon tongue.
the buildings where made out of bricks
Steel buildings settle at the same rate as traditional wood frame buildings do. It is the type of foundation that is more important.
Steel buildings typically are less to construct than wood or concrete. This is due to the cost of the equipment and materials.
