A support beam for a long functional unit, specifically in a paper and/or coating machine, including a long hollow body having a round or polygonal cross section and manufactured from a fiber reinforced material which was produced in a winding process, whereby the invention provides that the fiber reinforced material is one having a modulus of elasticity of >100 Gpa, and a heat expansion of <=2X10<-6 >1/° K in its longitudinal direction, as well as a fiber orientation whereby a first fiber content of 70% to 90% is approximately parallel to the longitudinal direction and a remaining second fiber content is aligned in the circumferential direction.
