Structural concrete composite deck a supported steel panel deck system filled with normal weight or structural lightweight concrete. Our lightweight concrete is custom blended as per the weight and thickness required for each particular job. Place reinforcement without attachment minimum 13 mm 1 2 inch above steel deck crests in insulating concrete.
