Span is the distance between supports.
The span of roof glazing is classified as the downslope dimensions between the centre lines of the fixing positions rather than the glazing bar length which is always longer than the span.

For a different appearance steel t or box sections can be used to support the glass joints within a glass roof.
Achievable spans are dependent upon many factors including.
These minimal steel supports can span large distances and can suit a more industrial effect design.
Three main factors for determining the weight load of your glass table top is glass thickness the square footage of the glass and the distance between the structural support eg.
Span for the purpose of using these tables span may be interpreted as the clear distance between supports measured along the beam.
Thicker glass table tops are capable of holding more weight.

For example a roof is subjected to a full snow load only a small percentage of time during the course of a year so this is factored into the roof s load calculation.
