steel sections are cold-formed, i.e. their manufacturing process involves forming steel sections in a cold state (i.e. without application of heat) from steel sheets of uniform thickness. These are given the generic title Cold Formed Steel Sections. Sometimes they are also called Light Gauge Steel Sections or Cold Rolled Steel Sections. The
5.3:COLD-FORMED STEEL PURLINS Engineering360Purlin spacing is dictated by the load-carrying capacity of the roof panels; a 5-ft spacing is common. Appendix B includes section properties for purlin sizes offered by some manufacturers. Cold-formed purlins are normally made of high-strength steel. Uncoated cold-formed members, still in the majority, usually conform to ASTM A 570 or A 607.

Metal Building Roof Purlin Line Strength by Computationa metal building roof purlin or girt line using AISI S100-16 North American Specication for the Design of Cold-Formed Steel Structural Members. A new Section I6.1 was added to the Specication in 2016 that provides instructions for calcu-lating purlin line strength as an alternative to pressure box testing.
Purlins and girts are complementary products to structural steel, used primarily in walls and roof of a building. All Canam Buildings purlins and girts are cold-extruded using high-strength steel to minimize weight while maximizing capacity of each section. As with all Canam Buildings products, our purlins and girts meet strict quality standards. A range of cold-extruded "C" and "Z" sections.
Secondary Framing Table of Contents - Nucor Building 1. Cold-formed box beams consist of two C or S sections, forming a cold-formed box. 2. These sections may be square or rectangular in shape. 3. The height of the box beam matches the purlin depth. The depth of the box beam will be 8, 10, or 12, depending on the design requirements of a particular project. 4. Cold-formed box beams are typically used as a replacement for the eave strut, eave purlin,
Steel Building Framing Systems Nucor Building SystemsNucor Building Systems supplies either cold-formed purlins or our open web bar joist system, Nucor ClearBay ®. The decision on which structural members to use will be based on the economy of each member, the roof system used, the product application, or by customer choice at the time of order entry.
These cold formed beams are perfect for roof and wall purlins. Z purlins are not like the hot rolled I-sections or U-channels in that they are thin-walled resulting in material savings of up to 20% for common loading and spans.
