Steel & Tube Launch Their New Profile - ST963

Steel & Tube’s ST963 profile has been specifically developed with unique design elements for superior performance over traditional high rib profiles.

Responding to industry feedback for a profile with more efficient cover than traditional high rib trapezoidal profiles, with stronger ribs and easy to walk on pans, Steel & Tube engaged in two years of rigorous
R & D resulting in the development of ST 963.

Numerous concepts were evaluated and reduced to seven different profile designs. These were subjected to computer modelling to provide theoretical indications of strength which reduced the number to four profiles. The four were all prototyped by hand-folding then tested on the MRM test rig. As a result two designs proceeded
 to the final stage. Two single-rib roll formers were built to provide accurate prototypes for the final decisive point load and wind uplift tests.
