Grill for the support of tubes, perfected, of the type formed by a reticulate determined by strips made of a material different from that of the frame and presenting a step of man with the respective cover, characterized by the fact that the step of man has a form similar to an isosceles trapezoid, whose greater base is formed by a frame portion, the smaller base by a strip essentially parallel to the preceding one, while the two sides are formed by two main strips and the corresponding cover is fixed to the internal grid of the grill, while on the side of the frame are provided one or more connections that limit only the tangential movements with respect to the frame, while one or more connections prevent movements perpendicular to the plane of the grid, but both allow free expansion in the radial direction .
