MARBLE RECTILINEAR MANHOLE GRATES

摘要

It is disclosed an integrated production line (one stop workshop) of standardized marble grate destined to cover rectilinear manholes with least production cost and enhanced quality features. The construction of said manhole grate is achieved by use either of a single uniform material (ornamental natural or artificial stone) or of two alternately-utilised different materials (e.g. marble combined with artificial marble or stainless steel or plexiglass).
