The present invention relates to a tread and handrail combination structure of a staircase, including a support post, multiple helically laminated treads mounted on the support post, and multiple juxtaposed handrails. Each tread has an outer side provided with multiple combination holes, so that two ends of each handrail may pass through the combination holes to be fixed on the tread. Each tread has a bottom face provided with a support tube aligned with one combination hole. One end of each handrail is screwed on the tread, and the other end of each handrail is extended through the combination hole and the support tube of the mating tread, and through the combination hole of a next tread, so that any two adjacent treads may be combined rigidly and stably, without deformation.
