OVERVIEW
clarkdietrich.com
This catalog is designed to help you select the right
products or systems for your construction applications.
Divided into six major sections, it is the most
comprehensive manual in the industry.
For your convenience, a comprehensive index containing
our complete product and system oering is also located
at the back of the catalog. Search by common names and
product names to help you quickly find exactly what you’re
looking for.
Structural properties and load tables are available on our
website at clarkdietrich.com.
HOW TO IDENTIFY OUR PRODUCTS
ClarkDietrich has adopted standard nomenclature
established by the American Iron and Steel Institute
(AISI) for identifying each of its products. Coding of each
member consists of four parts, in this order:
• A number which identifies the web depth of the
member to two decimal places: 600 = 6.00," 1000
= 10.00," 550 = 5.50," 362 = 3.625," etc.
• A letter that identifies the type of member, such as S = Stud/
Joist, T = Track, U = U-channel, and F = Furring channel.
• A number that defines the flange dimension in inches to two
decimal places: 162 = 1.625," 200 = 2.00," 125 = 1.25," etc.
• A number following a hyphen that denotes the minimum delivered
thickness in mils (33mils = 33/1000 inches which is approximately
0.0329"). Minimum delivered thickness is 95% of design thickness.
NOTE REGARDING PRODUCT SUBSTITUTION
Care should be taken when substituting materials in
place of ClarkDietrich building materials. There is a
misconception within the construction industry regarding
the substitution of one manufacturer’s products or
materials for those of another manufacturer. The
assumption is that all studs of a given size and steel
thickness are interchangeable. It may be possible that the
substitution can safely be made, but the decision should
not be made until the structural properties of the products
or materials involved are compared by a qualified engineer.
YIELD STRENGTH FY/PSI OR KSI
ClarkDietrich products are manufactured with steel having
a yield point of 33ksi for 18 and 20 gauge material. A yield
point of 50ksi is standard for 16 gauge and heavier material.
KSI = kips/square inch; kip = 1,000 lbs.
PROTECTIVE COATINGS
ClarkDietrich oers a wide variety of protective coatings
to meet the specific requirements of a project.
Non-structural products are coated to meet the minimum
requirements of ASTM C645, with a G40 or a protective
coating with an equivalent corrosion resistance including
coatings listed in Table 1 of ASTM A1003. Performance
coatings meet the metallic equivalency requirement of
C645 by satisfying section 9.1.3 of ASTM A1003 (75
hours in an ASTM B117 salt spray test). Non-structural
products may also be ordered with enhanced coatings for
special applications.
Structural framing products are available with a variety
of protective coatings that meet the CP60 coating
protection level requirements of AISI S200 and ASTM
C955. These coatings may include G60, A60, AZ50 or
GF30, all of which satisfy the above referenced standards.
G90 coatings are an enhanced option that can be
requested for highly corrosive environments. ClarkDietrich
can supply a specific or enhanced coating to meet specific
project requirements when requested. The buyer is solely
responsible to assure that product is ordered to properly
satisfy the applicable code or specification.
