An arch hangar is a structure with a curved roof in which the roof and the load-bearing element are combined in a single profile. Available in two configurations: frameless (roll-formed profile) and framed (trusses + metal decking).

Types of Arch Hangars
Frameless (roll-formed) Steel profile is roll-formed directly on site and curved into an arch. The most economical solution. Span — up to 30 m, ridge height — up to 10–12 m.
Framed arch Metal arch trusses + roofing material (profiled sheeting or sandwich panels). Allows spans of 60+ m and practically any height. More expensive, but more functional.
Where Arch Hangars Are Used
- storage of grain, feed and fertiliser;
- shelter for agricultural machinery and vehicle fleets;
- storage of construction materials;
- sports halls and covered arenas;
- temporary warehouses and industrial sites.
Advantages over Straight-Wall Hangars
| Criterion | Arch | Straight-wall |
|---|---|---|
| Snow load | Snow does not accumulate | Snow load calculation required |
| Cost | Lower (frameless) | Standard |
| Interior height | Uneven (lower at edges) | Uniform |
| Insulation | More complex | Easy |
| Appearance | Distinctive | Standard |
Limitations
- Side wall height: in a frameless hangar the walls are practically absent — the structure starts from the ground. This reduces useful volume at the edges.
- Insulation: attaching sandwich panels to an arched surface is considerably more complex than to a vertical wall.
- Expansion: a bay can only be added along the length, not the width.
