The support beam is an integrally-molded piece of a rigid plastic material or any other polymer or composite material, in particular a mixture of plastic material and saw dust. The support beam comprises a pair of spaced out lateral walls laid out in parallel. A plurality of spaced-apart and transversally-extending flanges are disposed between the parallel walls. The transversal flanges are configured and disposed according to at least one pattern at the end sections of the support beams and at least one pattern at the central section thereof. The support beam is designed in such a way as that the end sections have a higher compression strength than that of the central section.The support beam offers a very advantageous alternative to the support beams hitherto used for handling purposes, notably those made of solid wood or superimposed particle board sections. It can be used together with a corresponding support slat and fastened to the articles it supports with the help of a metallic belt or any other such type of fastener. The support beam is reusable, weather resistant, recyclable and possesses advantageous phytopathogenic properties.
