Industrial Shed Design Guide: Span, Height & Load Considerations
Quick Answer
Industrial shed design should start with three questions: what clear span does the layout require (machinery, racking, vehicle movement), what eave height accommodates crane hooks or stacking, and what floor and roof loads (including future equipment) does the structure need to carry — answering these before finalizing dimensions avoids costly mid-project changes.
Clear Span
Wider clear spans mean fewer internal columns, which is valuable for machinery layout flexibility and material handling but requires heavier primary steel members. The right span is determined by your actual operational layout, not by picking a round number.
Eave Height
Height needs to accommodate not just current equipment but crane hook height, racking stack height, and any ventilation or overhead conveyor systems. Under-specifying height is one of the most common and expensive design mistakes, since raising a structure after erection is impractical.
Load Considerations
- Dead load — the structure's own weight
- Live load — occupancy, movable equipment, maintenance access
- Wind load — per the site's IS 875 wind-speed zone
- Seismic load — per the site's seismic zone classification
- Crane load — if applicable, both static and dynamic (impact) loading from crane operation
