<br />Fabrication:
<br />Primary Framing:Rigid frames of shop-welded steel plate columns and rafters,both tapered and uniform depth sections as required by drawing,complete with allnecessarystiffeners,connection plates and holes for field-bolted assembly.
<br />Columns and Rafters:Fabricated with holes in web and/or flanges for attachment of secondary members.
<br />Splice Plates:Factory fabricated for precision for all rafter-to-rafter and/or column-to-rafter connections,complete with connection bolt holes.Base Plates,Cap Plates,Splice Plates and Stiffeners:Fabricate to sizes required,complete with all holes for connection of primary and secondary structural members.Factory weld into place.
<br />Join flanges and webs of structural members fabricated of plate or bar stock together by continuous automatic submerged are welding process with all weldingperformedbycertifiedweldersinaccordancewithstandardpracticesofAWSDl.I.
<br />Make all primary rigid frame field-bolted connections with A325 high-strength bolts of size required by building system Manufacturer.Clean all components of oil,dirt,loose scale,and foreign matters.Factory paint with one (1)coat of Manufacturer's standard shop coat.
<br />Endwall Framing:
<br />Precision hot rolled,and/or shop-welded steel plate members consisting ofraffers and columns fabricated for field-bolted assembly.
<br />Columns,Rafters,Splice Plates,Clips,Angles and Channels:Factory fabricate to size required.
<br />Plate Stock Endwall Framing Members:Join flanges and webs by continuous automatic submerged arc welding process,by welders certified in accordance withstandardpracticesofAWSD1.1
<br />Clean Components of oil,dirt,loose scale and foreign matter,per SSPC-SP2,and apply one (I)coat of Manufacturer's standard shop coat.Secondary Framing,(Purlins,Girts,Struts,Flange Braces,Base Angles,as required):Purlins
