Designation:A1085/A1085M15Standard Specification forCold-Formed Welded Carbon Steel Hollow StructuralSections(HSS)1This standard is issued under the fixed designation A1085/A1085M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers cold-formed welded carbonsteel hollow structural sections(HSS)for welded or boltedconstruction.These shapes are utilized in but not limited to thefollowing applications:buildings,bridges,towers,cranes,signsupports and poles,off-shore production and drilling platforms,roll-over protective structures(ROPS),falling object protectivestructures(FOPS),and amusement rides.1.2 This HSS is produced in welded sizes with a peripheryof 88 in.2235 mm or less,and a specified nominal wallthickness of 0.148 in.3.8 mm or greater and 0.875 in.22mm or less.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in non-conformance with thestandard.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.1.4 The text of this specification contains notes and foot-notes that provide explanatory material.Such notes andfootnotes,excluding those in tables and figures,do not containany mandatory requirements.2.Referenced Documents2.1 ASTM Standards:2A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA700 Guide for Packaging,Marking,and Loading Methodsfor Steel Products for ShipmentA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and Ferroalloys2.2 Military Standard:3MIL-STD-129 Marking for Shipment and Storage2.3 Federal Standards:4Fed.Std.No.123 Marking for ShipmentFed.Std.No.183 Continuous Identification Marking of Ironand Steel Products2.4 AIAG Standard:5B-1 Bar Code Symbology Standard3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,refer to Terminology A941.4.Ordering Information4.1 Orders for material under this specification shall containinformation concerning as many of the following items as arerequired to describe the desired material adequately:4.1.1 Quantity(feet metres or number of lengths),4.1.2 Name of material(cold-formed HSS),4.1.3 Size(outside diameter and wall thickness for roundHSS,and outside dimensions and wall thickness for square andrectangular HSS),4.1.4 Length(random,multiple,specific;see 12.4),4.1.5 End condition(see 17.3),4.1.6 Burr removal(see 17.3),4.1.7 Certification(see Section 19),4.1.8 ASTM specification designation and year of issue,4.1.9 End use,4.1.10 Special requirements,4.1.11 Bar coding(see 20.3),4.1.12 Packing,Marking and Loading(see Section 21),and1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.09 on Carbon Steel Tubular Products.Current edition approved Nov.15,2015.Published November 2015.Originallyapproved in 2013.Last previous edition approved in 2013 as A108513.DOI:10.1520/A1085_A1085M-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/dodssp.daps.dla.mil.4Available from U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401,http:/www.access.gpo.gov.5Available from Automotive Industry Action Group(AIAG),26200 Lahser Rd.,Suite 200,Southfield,MI 48033,http:/www.aiag.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.1.13 Supplementary requirement,if any,including theadditional requirement called for in the supplementary require-ment.5.Process5.1 The steel shall be made by one or more of the followingprocesses:open-hearth,basic-oxygen,or electric furnace.5.2 When steels of different grades are sequentially strandcast,the steel producer shall identify the resultant transitionmaterial and remove it using an established procedure thatpositively separates the grades.6.Manufacture6.1 HSS shall be made from flat-rolled steel by the electric-resistance-welding process.The longitudinal butt joint ofwelded tubing shall be welded across its
