This paper describes a relatively new joining technique for cold-formed steel structures called press-joining. Press-joining is a technique whereby a joint is created from the sheets to be connected, requiring no additional fixing items. A series of shear test results are given.The effect of UTS, steel thickness and angle of inclination of the join on both strength and deformation characteristics of the press-join are discussed.A theoretical expression based on the results is developed linking all of the influencing factors to the shear strength of the join.
