Disclosed is a porous filter support plate of the kind used in traveling bridge filters for the support of granular filter media used in the filtration of waste water, industrial liquors or baths, or for filtration of potable water in a water purification system. The support plates are formed of porous, heat-fusible materials, for example, a thermoplastic organic material, joined together by heat-fused butt joints and/or reinforced by vertical zones which extend vertically through the plates in which the material has been brought to a molten state and is pressed together to form a dense, solid, non-porous mass.
