2.4.2 Roll Forming The roll forming machine is a custom built hydraulically operated device used to reshape 18 to 24 gauge galvanized sheet steel coil stock ranging in width from approximately 6 - 9 inches, into a rectangular cross section. The roll forming operation is accomplished with a series of sequential metal forming dies in the roll former that converts galvanized sheet steel flat stock into the final stud configuration. 2.4.3 Component Customization The roll forming machine is computer controlled. The computer program defines the parameters of the finished wall panel and trusses. The programmed variables adjust for metal thickness, locate and punch holes in the wall studs for conduits of plumbing, sanitary sewer water, potable water, electrical and data services. In addition to the holes for construction services, holes are also fabricated for the mechanical fasteners forming the studs into a wall, a truss, or other construction component. The roll former's final operation is to shear the stud or truss member to the correct length. Theses components can be used as a free standing stud or utilized in a prefabricated wall panel or truss. 2.4.4 Wall/truss Assembly Assembly/flip tables are located in close proximity to the roll forming equipment. The completed studs or components are transferred to the assembly/flip table for fabrication as a wall section or truss section. Assembly is accomplished with pneumatic tools utilized to fasten the components into designed structural components. Assembly fasteners include rivets, screws, bolts and nuts, and nails. Various fasteners are of proprietary design. 2.4.5 Wall/truss Stacking The finished studs or construction components are stacked inside the factory or outside the factory in truss stacking equipment located in the back lot. After the components are stacked for delivery the material is secured using plastic banding for transport to the construction site. 2.4.6 Truck Loading NexFrame has numerous trailers on which the completed stacks of wall panels, trusses and floor systems are loaded for transport to the construction site. Stacking and loading generally requires three to four hours to complete, after which the material is transported to the construction site. 2.5 FACILITY 2.5.1 NexFrame LP 2.5.2 SIC Code: 3441, Fabricated Structural Metal 2.5.3 Area: 10 acres, approximately. 2.5.4 Percentage covered and impervious: 98% impervious and does not have soil erosion due to the absence of exposed dirt.
