Lightweight Steel Frame House Construction Hand... __HOT__
Steel framing offers a strong, accurate, stable, and durable framing alternative to traditional wooden frames. In fact, lightweight steel framing is the superior choice for residential construction. Steel frames come in a wide range of sizes and shapes, much more so than standard lumber, and yield a high-quality home.

Steel-framed houses suffer from relatively poor insulation and low energy efficiency. This is because steel conducts more heat than wood does, reducing the insulating properties by 60% because of thermal bridging. This may lead to higher energy costs.
One effective way for a homeowner to counteract this problem is to wrap insulation board around the steel beams, in addition to typical insulation between studs. Another option is using hybrid steel/wood frames, which take advantage of both steel and wood's strength, durability, and support benefits. A local insulation contractor will be able to tell which solution fits your home.
Steel framed homes are durable but have limitations when it comes to roofing designs. Unlike wood roofs, metal-framed roofs rarely have high pitches or dormers. Adding a wooden frame for the roof of a steel-framed home can solve this design problem, though.
Steel frames are slightly more expensive than their wood frame counterparts. To install steel frames, builders need special tools. Making metal frames will cost between 10 and 20% more than wood frames. Add additional insulation costs, rust prevention, and any extra work when adding or modifying walls when you hire qualified house framing contractors.
Buying a house is a major purchase that may or may not come along once in a lifetime. You want to value not only the design but also the structural security that will protect your house and the people who live in it. In Japan, there are several types of construction methods and steel construction is one of them.
Steel construction is characterized by its wide range of applications. It is used not only for detached houses, but also for apartments, condominiums, and buildings where greater strength is required.
There are two types of steel frame construction: heavy steel frame construction and light steel frame construction. These are differentiated according to the thickness of the steel used, with "heavy steel frame construction" being used for steel materials 6 mm or thicker, and "light steel frame construction" for steel materials less than 6 mm thick.
Lightweight steel construction is the most common construction method for detached houses and apartments. Since it does not cost as much as heavy steel construction, it is relatively easy to be chosen as a structure of middle-scale housing and apartments.
The earthquake resistance of a light steel frame construction is greater than that of a wooden structure, and is more likely to limit damages from earthquake disasters than wooden houses.
The prefabrication method used for lightweight steel-frame buildings is completed by manufacturing the main components in advance at factories and assembling the parts on site. This eliminates the need for extensive on-site construction work and shortens the construction period, thereby reducing labor and other construction costs.
The steel construction also allows for high ceilings in the rooms. It gives an open and light atmosphere to the space. You can live comfortably in a space with a large trajectory that connects the ground floor to the top floor.
In this example, a concrete building is built on top of two cylindrical steel-frame diagonals against a sloping site. By supporting the building only with steel frame components, a simple form of architecture is built in magnificent nature in accordance with the complex topography of the site.
The steel-frame structure has a long service life. In particular, steel structure buildings can maintain large spaces, making it easy to create houses with flexible floor plans and high ceilings. It can also be built on special lots by mixing it with other structures.
Steel frame construction can be used not only for new housing, but also for renovating old interiors to make them more livable and fresh. This is one of the construction methods that we highly recommend to those who are considering building their own home in the future.
Because Cold-formed steel (CFS) framing is light weight, extremely strong, noncombustible, and relatively easy to install, it has dominated the market for interior, non-loadbearing partition walls in commercial construction. Now, with advanced technological developments like panelized systems, the building community is using CFS for structural applications in mid-rise and multi-housing buildings.
Given those advantages, some builders have found that ordering factory-manufactured steel panels and trusses is an ideal way to move into steel framing because it minimizes the need for skilled framers, and provides access to experienced design and layout pros.
Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.
Building framing is divided into two broad categories, heavy-frame construction (heavy framing) if the vertical supports are few and heavy such as in timber framing, pole building framing, or steel framing; or light-frame construction (light-framing) if the supports are more numerous and smaller, such as balloon, platform, or light-steel framing. Light-frame construction using standardized dimensional lumber has become the dominant construction method in North America and Australia due to the economy of the method; use of minimal structural material allows builders to enclose a large area at minimal cost while achieving a wide variety of architectural styles.
Historically, people fitted naturally shaped wooden poles together as framework and then began using joints to connect the timbers, a method today called traditional timber framing' or log framing. In the United States, timber framing was superseded by balloon framing beginning in the 1830s. Balloon framing makes use of many lightweight wall members called studs rather than fewer, heavier supports called posts; balloon framing components are nailed together rather than fitted using joinery. The studs in a balloon frame extend two stories from sill to plate. Platform framing superseded balloon framing and is the standard wooden framing method today. The name comes from each floor level being framed as a separate unit or platform.
Framed construction was rarely used in Scandinavia before the 20th century because of the abundant availability of wood, an abundance of cheap labour, and the superiority of the thermal insulation of logs; hence timber framing did not take off there first for unheated buildings such as farm buildings, outbuildings and summer villas, and for houses until the development of wall insulation.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a wall. The platforms may be the boxed structure of a ceiling and roof, or the ceiling and floor joists of the story above. In the building trades, the technique is variously referred to as stick framing, stick and platform, or stick and box, as the sticks (studs) give the structure its vertical support, and the box-shaped floor sections with joists contained within length-long post and lintels (more commonly called headers), support the weight of whatever is above, including the next wall up and the roof above the top story. The platform also provides lateral support against wind and holds the stick walls true and square. Any lower platform supports the weight of the platforms and walls above the level of its component headers and joists.

Light-frame materials are most often wood or rectangular steel, tubes or C-channels. Wood pieces are typically connected with nail fasteners, nails, or screws; steel pieces are connected with pan-head framing screws, or nuts and bolts. Preferred species for linear structural members are softwoods such as spruce, pine and fir. Light frame material dimensions range from 38 by 89 mm (1.5 by 3.5 in); i.e., a Dimensional number two-by-four to 5 cm by 30 cm (two-by-twelve inches) at the cross-section, and lengths ranging from 2.5 metres (8.2 ft) for walls to 7 metres (23 ft) or more for joists and rafters. Recently,[when?] architects have begun experimenting with pre-cut modular aluminum framing to reduce on-site construction costs.
Wall sections usually include a bottom plate which is secured to the structure of a floor, and one, or more often two top plates that tie walls together and provide a bearing for structures above the wall. Wood or steel floor frames usually include a rim joist around the perimeter of a system of floor joists, and often include bridging material near the center of a span to prevent lateral buckling of the spanning members. In two-story construction, openings are left in the floor system for a stairwell, in which stair risers and treads are most often attached to squared faces cut into sloping stair stringers. 041b061a72
