ROC INC has the motivation and expertise to provide the custom fabricated structural members for your next project.
We provide a full line of light gauge cold-formed steel sections for use in secondary framing applications. Steel sections provide economic secondary structural framing for pre-engineered metal buildings, carports, canopies, walkway covers, parking covers and eyebrow canopies. They are also used as the primary structural framing of single story mini-storage structures.
The sections are available in 16 Gauge (.060")*, 14 Gauge (.077")* and 12 Gauge (.099")* thicknesses. Zee, Cee and Channel standard sizes are 4" to 12" depths (even 2" increments). Angle standard sizes are 2"x 2", 2"x 4" and 3"x 3". Eave Strut standard sizes are 8"x 5"x 2 1/2" and 8"x 5"x 5". These sections are available with either a red-oxide prime or hot-dipped galvanized protective coating. Red-oxide members are manufactured from ASTM A570 Grade 55 steel (55 KSI minimum yield strength).
Galvanized members are manufactured from ASTM A653 G-90 Galvanized Grade 55 steel (55 KSI minimum yield strength). ROC INC’s provisioning capabilities produce zee purlins to symmetrical or asymmetrical designs. Eave Struts can be produced for high and low eaves and are available in single and double slope configuration. Standard purlin punching patterns include A, B, C, G and H web punching which allows for simple span, short lap and long lap conditions. Custom punch patterns and custom shapes are available; please consult your ROC INC representative for details.
*Thicknesses indicated represent design thicknesses. Minimum deliverable bare steel thickness equals 0.95 x design thickness in accordance with Section A3.4 of the AISI Specifications for minimum steel thickness in inches.
