C "C" Section A member formed from steel sheet in the shape of a block "C", that may be used either singularly or back to back. A crane controlled by an operator in a cab supported on the bridge or trolley. Camber Curvature of a flexural member in the plane of its web before loading. Canopy A projecting roof system that is supported and restrained at one end only. Cantilever Beam A beam supported only at one end having a free end and a fixed end. Cap Plate A plate located at the top of a column or end of a beam for capping the exposed end of the member.
A ridge cap is normally installed only after all metal roof panels and any other trim are in place. Metal Roofing Closures To keep debris, insects and blowing rain from getting in under the gaps between the panels and the ridge cap, closure strips are used. Closures come in two types: They come in 3-foot-long pieces, designed to fit closely over the ribs of the roof panels. They are placed end to end and secured along the edge of the top row of panels, where panels and ridge cap will meet. Each piece is also designed to interlock with the next.
There are lots of little pieces involved when it comes to the assembly of a pole building, which the average lay person would have little or no knowledge of. Imagine you are inside of your brand new steel roofed pole building, enjoying the wonderful space. Along the eave where water drips off when it rains side, are the underside of the high-ribs of the steel roofing. Having inside foam closure strips installed along the eave sides of the roof steel can be the difference between a happy or unhappy pole building owner.
