The invention belongs to the field of building materials and in particularly relates to a light-gage steel joist, comprising a bottom plate and two symmetric vertical sides; and reinforcing ribs are uniformly distributed on the bottom plate and the internal and external surfaces of the two vertical sides. The reinforcing ribs have an angle of 45 degrees with the length direction of the light-gage steel joist. The direction of the reinforcing ribs on the internal surfaces is opposite to that on the external surfaces. The distance between two adjacent reinforcing ribs is 3-10mm. The light-gage steel joist has the following advantages and positive effects: the strength of the light-gage steel joist is increased and the load-bearing capacity is strengthened; and the light-gage steel joist is simple in structure and low in processing cost and the like.
