If you’re unfamiliar with cold-formed steel (CFS) framing or simply haven’t used it in a while, you may have several questions: What is it? How can I use it? Why should I use it? CFS certainly isn’t a new building material. It actually has been used in North America for over 100 years. Because of its light weight and durability, it can be used in a range of applications — from interior, non-loadbearing partition walls to structural members in mid-rise and multi-family buildings. Whatever your current level of knowledge, consider this eBook a primer on all things CFS framing. In it, you’ll learn what CFS is, how it can benefit a construction project, the basics of designing with and ordering CFS, and training options for expanding your CFS knowledge.
如果对冷型钢框架不熟悉或有一段时间没有使用过,可能会有这样的疑问。我怎么使用它?我为什么要使用它?CFS肯定不是一种新的建筑材料。事实上,它在北美已经使用了100多年。由于其重量轻和耐久性,它可以用于从室内、非承重隔墙到中高层和多户型建筑的结构构件的一系列应用。无论你目前的知识水平如何,请将这本电子书视为关于CFS框架所有内容的初级读本。在本教程中,您将了解什么是CFS,它如何使构建项目受益,使用CFS进行设计和排序的基础知识,以及扩展CFS知识的培训选项。
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.
由于冷弯钢(CFS)框架重量轻,强度极高,不燃,而且相对容易安装,它在商业建筑的室内非承重隔墙市场占据了主导地位。现在,随着面板系统等先进技术的发展,建筑社区正在将CFS用于中高层和多住宅建筑的结构应用。
In fact, cold-formed steel framing is rapidly becoming the material of choice for student dormitories, assisted living facilities, and hotels across the country where prudent developers are interested in maximizing their return on investment.
事实上,冷弯钢框架正在迅速成为学生宿舍、辅助生活设施和全国各地的酒店的选择材料,谨慎的开发商感兴趣的投资回报最大化。

What is cold-formed steel?

Cold-formed steel (CFS) members are made from structural quality sheet steel that are formed into C-sections and other shapes by roll forming the steel through a series of dies. No heat is required to form the shapes (unlike hot-rolled steel), hence the name cold-formed steel. A variety of steel thicknesses are available to meet a wide range of structural and non-structural applications.
冷弯钢(CFS)构件是由结构质量好的钢板通过一系列模具辊压成形而成的c型和其他形状。形成这种形状不需要热量(不像热轧钢),因此被称为冷弯钢。各种钢的厚度可以满足广泛的结构和非结构应用。

Value-benefit of steel

CFS as a construction material has many advantages. For example, CFS doesn’t shrink or split, won’t absorb moisture, and resists warping, termites, and fire.
CFS作为一种建筑材料有许多优点。例如,CFS不会收缩或开裂,不会吸收水分,并抗翘曲,白蚁和火灾。
As a uniformly manufactured product, the quality of CFS is very consistent. That consistency translates into less scrap to haul off because there is less waste — all of it recyclable. In addition to lowering scrap disposal expense, the fire resistance of CFS framing also can help reduce project costs through discounts on builders’ risk and other course of construction insurance requirements.
作为统一生产的产品,CFS的质量是非常一致的。这种一致性转化为更少的垃圾,因为垃圾更少——所有的垃圾都是可回收的。除了降低垃圾处理费用,CFS框架的防火性还可以通过降低建筑商的风险和其他建设保险要求,帮助降低项目成本。
CFS’ physical properties allow it to be used in a wide range of environments. It’s strength and ductility, for example, make it ideal for construction in regions subject to high winds or earthquakes. Moreover, a study, conducted by the National Association of Home Builders (NAHB) Research Center, showed that the zinc coating on steel framing materials can protect against corrosion for hundreds of years.
CFS的物理特性允许它在广泛的环境中使用。例如,它的强度和延展性使其成为强风或地震地区的理想建筑材料。此外,一项由全国住宅建筑商协会(NAHB)研究中心进行的研究表明,钢框架材料上的锌涂层可以抵御数百年的腐蚀。
And because each piece of CFS contains a minimum of 25 percent recycled content, is 100 percent recyclable at the end of its lifespan, and emits no volatile organic compounds — it’s an exceptionally sustainable building material.
因为每一块CFS都含有至少25%的可回收成分,在使用寿命结束时是100%可回收的,并且不排放挥发性有机化合物——它是一种特别可持续的建筑材料。

On the jobsite

CFS also provides numerous advantages in terms of the construction process itself. CFS is light making it easy to ship, handle and assemble.
CFS在施工过程本身也提供了许多优势。CFS重量轻,便于运输、搬运和组装。
Moreover, greater strength means less material. For example, if a project calls for stick framing, the strength of CFS allows it to be installed on 24” centers rather than traditional 16” centers — meaning fewer studs to install.
此外,更大的强度意味着更少的材料。例如,如果一个项目需要木棍框架,CFS的强度允许它安装在24”中心,而不是传统的16”中心,这意味着安装更少的螺栓。
And because CFS is manufactured to exacting standards, it is ideally suited for manufacturing into panels and trusses which — because CFS is light in weight — can be quickly and easily installed with fewer framers on the job.
由于CFS是按照严格的标准制造的,它非常适合制造面板和桁架,因为CFS重量轻,可以快速、轻松地安装,而工作中的框架工人很少。
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.
鉴于这些优势,一些建筑商发现,订购工厂制造的钢板和桁架是进入钢框架的理想方式,因为它最大限度地减少了对熟练的框架师的需求,并提供了经验丰富的设计和布局专业人士。
In addition to speeding up the framing process, CFS panels contain pre-punched holes designed to accommodate rapid mechanical, electric and plumbing installation after the framing is complete.
除了加快框架过程,CFS面板包含预先冲孔设计,以适应快速机械,电气和管道安装框架完成后。
