22<br />Metal Framing –Evolution of Cold-Formed Structural & Non-Structural Framing<br />Began around 1850. In North America, 1946.<br />Some of the countries using the system today:<br />USA, CANADA, WESTERN & EASTERN EUROPE, CHINA, Austria, New Zealand, India, Malaysia, Indonesia, South Africa, Gulf countries, and Algeria.<br />What is Cold-Formed Steel?<br /><ul><li>Made from structural quality sheet steel that are formed into shape either through press-braking blanks sheared from sheets or coils, or more commonly, by roll forming the steel through a series of dies. No heat is required to form the shapes (unlike hot-rolled steel), and thus the name cold-formed steel.
Cold-formed steel members and other products are thinner, lighter, easier to produce, and typically cost less than their hot-rolled counterparts.
A variety of steel thickness is available to meet a wide range of structural and non-structural applications. </li></li></ul><li>Why consider CFS?<br />Advantages of CFS Framing<br />Cold-formed steel framing is a versatile structural product for use in load-bearing and curtainwall construction, floor and roof assemblies, mansard and truss frames, as well as interior nonstructural partitions. <br />There are several reasons for this increased interest in steel framing. The popularity of corrosion resistant, galvanized steel framing can be attributed to these documented benefits:<br />Design Flexibility.<br />Speed: Reduced field labor<br />Code Compliance. Cold-formed steel framing is code approved (IRC, IBC, CABO and ICC).<br />Cold formed steel is a LEED™ certified product based on its virtually 100% recycled steel content.<br />Common Appearance.<br />Consistent Quality.<br />Ease of Installation.<br />Highest strength-to-weight ratio of any building material<br />Light Weight. <br />Fire Safety - 100 % Non-combustible.<br />23<br />
Durability of Galvanized Steelng for Residential Building<br />Do Steel Homes Corrode?<br />A study of Durability of Galvanized Steel Framing for Residential Building by the International Zinc Association (IZA) that measures actual zinc and zinc alloy coating corrosion rates of steel framing samples in four different home environments in the U.S.A. and Canada. The NAHB Research Center, a subsidiary of the National Association of Home Builders (NAHB) was the research contractor. Results presented in this summary report are based on the corrosion data presented in the Research Center’s seven-year sample retrieval report that is available from IZA or from the Steel Framing Alliance’s online store at www.steelframing.org.<br />Estimated life expectancy based on the average mass loss (using nominal coating weights) ranged from 280 to over 1000 years with an average of 611 years for all samples at all locations.<br />24<br />

Designing with CFS Framing<br /> there are a few "design tips" that may be valuable to the first-timer or novice user:<br /><ul><li>A team approach involving the contractor-builder-manufacturer-designer-owner is encouraged.
Understanding appropriate steel framing methods and practices.
Follow applicable Occupational Safety and Health Administration (OSHA) guidelines and safety requirements.
All structural members shall be aligned vertically (in-line framing) to transfer all loads to the foundation, unless horizontal load distribution members are specified.
When connecting steel to steel members, drilling tools should drive screws at low speeds of 2500 rpm to prevent improper installation.
Keep plumbing in the slab and route through floor and interior wall cavities to the greatest extent possible.
Avoid locating plumbing in exterior walls because of potential interruption of structural members and a reduction of the thermal value of the wall.
Don't forget web stiffeners for bearing points of floor joists. These are essential components. Stiffeners can be installed on either side of the joist's web.
Snap-in plastic insulators, grommets, conduits, or other approved wire protection methods should always be used to protect the plastic sheathing on electrical cables and wires when passing through holes in CFS members.
Ensure that copper pipes are always separated from the steel framing by using plastic insulators or other approved methods.
All load-bearing studs shall be seated in the tracks with a maximum gap of 1/8 inch between the end of the stud and the web of the track.
Finally, there is no substitute for doing your own homework—explore the resources mentioned in this article and become informed in the various attributes of CFS systems.</li></ul>39<br />

E.I.F.S. – Light Gauge Metal Walls Assembly<br />There are several reasons for the continued growth of the EIFS market:<br />Lightweight:<br /> They are lightweight and hence impose few structural restrictions on their use;<br />2. Range of Colors:<br /> The polymer-based finishes allow for a vast range of colors and textures;<br />3. Design Flexibility:<br /> The foam plastic insulation used by most systems can be easily shaped to form cornices, reveals, trim, etc.;<br />4. Energy Efficient and economy:<br /> The insulation improves energy-efficiency by wrapping the whole building in an uninterrupted blanket.<br />55<br />
E.I.F.S. – moisture and thermal performance<br />An Oak Ridge National Laboratory study shows that a newly redesigned generation of Exterior Insulation and Finish Systems, or EIFS, walls perform better than several other wall types tested for moisture and thermal performance. EIFS walls use foam insulation, fiberglass mesh and performance-engineered coatings as an alternative to various other cladding systems. ORNL researchers teamed with construction industry EIFS partners to develop "water management systems" that greatly improve durability, moisture management and thermal performance of the EIFS walls. The 15-month ORNL study conducted in the Southeast showed EIFS outperformed walls made of brick, stucco, concrete block and cement board in moisture protection and temperature control. The data are being used to benchmark a computer simulation, called a hygrothermal model, to predict wall thermal and moisture performance. The work is funded by the Department of Energy's Office of Energy Efficiency and Renewable Energy and the non-profit EIMA Industry Members Association.

The ProcessA superior end-to-end process<br />Architects Renditions: The process begins with an architect’s design that can then be transferred to framing, detailing and engineering software.<br />Engineering: The entire frame is then designed and detailed using framing software. The completed file, then ready for manufacturing, is sent electronically to the Steel Framing equipment.<br />Production: The Steel Framing equipment then creates each component of the building frame individually, labeling them according to their location in the frame for error free construction.<br />Individual Components: Every component is produced and detailed with individual characteristics according to its position in each panel. Cut to length, service and fastening holes pre-punched, swaged, notched and ready for assembly.<br />Assembly: The assembly process usually takes place at the manufacturing plant as each finished component is produced by the Steel Frame Roll former. They are assembled and screwed together to form the panels and trusses.<br />Transport: The completed panels and trusses are then transported to the construction site.<br />Construction: Once at the construction site, the panels and trusses are unloaded and positioned for rapid and accurate assembly.<br />Finished Product: Once the frame is completed, the rest of the structure is built.<br />Combining the processes of designing, quoting, production planning, factory management, machine control, and material management.<br />By integrating the above processes results in:<br /><ul><li>Increased efficiency.
