How does the Metal Building Industry Utilize Components?
There is a diversity in the industries involved in the production of components used in the metal building industry.
Today there is an increased amount of metal and metal components being used in the building industry. Through organizations such as MCA (Metal Construction Association) a tremendous amount of information on research, market development, trends, technical information and codes and standards has been gathered and made available to the building communities. By way of education more communities will be made aware of the benefits and in turn contribute to the increased use of metal.
Metal buildings consist of three main component systems: the structural steel framing system, the metal roof system and the wall panel system. All components from bolts to beams come from some type of steel or metal fabricator. Logan Stampings fabricates a number of metal building components. Roof clips, splice plates, rake trim, gutter supports and brackets, closures, structural hats and sub purlins, bearing plates and miscellaneous trim pieces are all fabricated in-house at our Logansport and Peru facilities.
Logan Stampings participates in the fabrication and manufacturing of various metal components.
Metal Roof Panels
Metal roof panels are of the screw-down or mechanically seamed type. The panel design is determined during the architectural and engineering processes based on performance needs and aesthetic preferences. Mechanically seamed roof systems (standing seam) are installed by methods other than typical through fastener attachment. Metal roof clips, which are designed according to a specific panel detail, are used in the panel installation. ‘Clips’ are attached to the male side of the leading roof panel, secured to the substrate / framing and lapped by the corresponding female side of the following panel. The ‘clip’ is screened by the seaming process providing a concealed fastener installation.
Clip designs are specific to the dimensional panel characteristics and seam orientation. Two common styles are the ‘floating’ and the ‘fixed’ clip. ‘Floating’ clips are designed to move as the roof system moves due to the effects of expansion and contraction. The movement of the roof can be influenced by design loads, changes in temperature both interior and environmentally, wind loads and other environmental influences. The ‘fixed’ clip is designed to do as its name implies: once the roof is installed by attaching to the substrate / framing it does not move.
As with any installation, proper design, material and component selection, placement, alignment and attachment are essential to provide the full benefit and life of the roof system.
Stamping / Stamped Parts
Stamped parts replaced die forging and machining as a result of greatly reduced costs and efficiency.
Stamping, often referred to as pressing, is a process where blank sheets or coil stock of sheet metal are fed into a machine and tool and die surfaces work to ‘form’ the metal into desired parts. When several operations are completed in succession by way of feeding material through a set of dies one step at a time it is referred to as Progressive Stamping. These processes may take place in a single stage operation meaning a desired part is produced with each ‘stroke’ of a machine or with multiple stages, or secondary, operations.
We perform several various processes such as punching, piercing and blanking. We also perform forming or notching, embossing or gusseting and hardware insertion. Tog-L-Loc, spot welding, tapping, coining, countersinking and deburring are other available processes.
Along with standard production we also offer prototypes, production, assembly, and outside finishing services.
