9. MATERIALS. The marking standard used in the following material does not have a metric
equivalent. Materials marked to the following standard are for field acceptance of the delivered
materials. Designers are to use the nominal uncoated material thickness as shown on the drawings
and within the specification.
a. Markings. The Metal Lath / Steel Framing Association (ML/SFA), Metal Stud Manufacturers
Association (MSMA), the AISI Residential Advisory Group (RAG), and the Prescriptive Standard for
Steel Framing, accepted by the Council of American Building Officials (CABO), have adopted a
standard method of marking all cold-formed steel members. The markings will be on the web of the
section and will be repeated throughout the length at a maximum of 1219 mm (48 inches) on center.
There is no defined size or method of marking, but the markings must be legible and easily read. The
product marking will include the following information:
(1) Manufacturer identification. Manufacturer's Name, Company Logo or emblem will be
displayed to clearly identify the product manufacturer.
(2) Minimum delivered uncoated steel thickness. Material thickness without coatings or
galvanizing is represented in mils of the decimal thickness value for example 0.84 mm (33 mil);
(3) Protective coating designator. The galvanizing coat designator will indicate the amount
level of protection being provided such as: G-40-EQ, G-60-EQ, or G-90-EQ, where EQ is an equivalent
protective coating to the designated galvanized coating.
(4) Minimum yield strength. Material strength in kips per square inch (ksi)
b. Nomenclature.
(1) Standard Nomenclature for Manufacturer's Catalogs:
(a) The first set of numbers will represent the depth of the section to two decimal places
without the use of a decimal point.
(b) A Letter following the depth of the section will define the shape of the section per the
following:
"S" = CEE shaped Stud
"U" = Channel shaped Stud
"T" = Track
"F" = Furring Channel
(c) The second set of numbers will represent the flange width to two decimal places
without the use of a decimal point.
(d) The last set of numbers will be the minimum delivered thickness in mils and be
preceded by a dash (-).
