STEEL THICKNESS
The steel thickness of a product or component is
referenced in terms of gauge or mils. The mil thickness
measures the uncoated base metal material, and is a key
contributor to the strength of the product.
Note: All products comply with ASTM standards and federal
specifications as shown in the Code Approvals and Performance
Standards in the back of this catalog. Minimum thickness is 95% of
the design thickness, per AISI code. One mil is equivalent to 1/1000
(0.001) of an inch. So, a 20 gauge stud measuring the minimum
uncoated base metal at 0.030 inches is 30mils thick.

PRODUCT LABELING
Skids are easily identified with master skid labels that
display product, gauge, size, length, piece count, yield
strength and any special skid markings specified at the
time of order. Individual inkjet labeling (including company
name, product, size, length, gauge, coating and yield
strength) or embossing is also provided on many of our
structural framing members. UPC bar coding is also
available for certain products.
METRIC SPECIFICATIONS
At your request, ClarkDietrich will provide “soft” metric
conversions on its products and systems to help specifiers
match metric design sizes. In addition, some products
are available with hard metric dimensions from selected
manufacturing facilities.
STANDARDS & SPECIFICATIONS
All structural properties are developed in accordance with
the American Iron and Steel Institute’s “Specification for
the Design of Cold-Formed Steel Structural Members.”
