What is the thickness of cold formed steel?

Typical thickness of cold-formed steel section is ranged from 0.9mm to 3.2mm. The steel is usually galvanized to protect the members from corrosion which will make it more durable. The strength of cold-formed steel is higher than hot-rolled steel per unit weight.See all results for this questionWhat is the nominal shear strength of a screw connection?Currently, there are equations for predicting the nominal shear strength of a screw connection given in the American Iron and Steel Institutes North American Specification for the Design of Cold-Formed Steel Structural Members. In an effort to increase the scope of application of the nominal shear strength equations, studies by Rogers and See all results for this questionWhat is the design strength of screw connection?Currently, the specification includes provisions that assess the design strength of a screw connection subject to pure tension, pure shear, and combined tension pull-over and shear forces. Additional guidance is required to determine the design capacity when screw connections are subject to both combined tension pull-out and shear forces.Reference: scholarsmine.mst.edu/cgi/viewcontent.cgi?article=1271&context=isccssSee all results for this question
