Components of steel buildings, such as I-beams, gutters and down spouts, sidewalls and end wall panels, and even standing seam roofs are systematically manufactured in designated areas called "lines" throughout the metal building factory. Each manufacturing line completes a specific function, automated by use of conveyors that move the steel sheeting, I-beams and fabricated metal components from station to station. Since each steel building is manufactured to order, building components are produced as required to fulfill each steel buildings exact specifications.
The manufacture of steel buildings rafters and columns begins with the Plasma Table. The Plasma Table cuts the web, the center of the rafter or column (like the center of the letter "H"). The web moves to a holding station waiting to move by automated conveyor to the station where the web will be tack-welded to the flange.
The flange machine cuts flanges into specified lengths determined by the pre-engineered buildings specifications from steel bar stock. After cutting, the flanges move to a holding station waiting to move by automated conveyor to the station where the flanges will be tack-welded to the web prior to going through the automatic welding machine.
Certified welders tack-weld flanges and webs in place to form rafters and columns. The tacked rafters and columns move by conveyor to the PHI machine. At the PHI machine, an automatic welding process fuses the web and flange materials, permanently welding the flanges to the web. A Welding Inspector checks all welds to ensure that strict AISC standards are met.
Roof and sidewall panels are fabricated from steel sheeting. Large coils of metal sheeting are placed in a machine called an "uncoiler" which passes the sheeting through another machine called a "straightener" that straightens the sheet. The straightened sheet is die cut and passes through a roll former to give the straightened sheet the shape of roof or sidewall sheeting. As with all machinery in the steel building factory, computers are feeding information to the metal corrugation machine giving it the exact specifications for each building.
Sophisticated machinery on the Trim Line automates the process by which custom trim is formed and ensures exact bends and perfect angles. Starting with a coil of steel mounted on an uncoiler, the steel passes through a straightener to a series of ten roll formers that form the shape of each trim and make all trim components: rake trim, corner trim, jamb trim, head trim, base trim, eave trim, rake angle, base angle, gutter straps, downspouts and gutters.
Out in the yard the Staging Department gathers all the steel building components and carefully loads them onto trucks to deliver the building to the job site. Special attention is given to the Bill of Materials ensuring that every order is complete and accurate. The Traffic Office handles the shipment of each building, scheduling trucks and coordinating buildings to arrive at the job site on time where the erection crew is waiting for delivery.
