THA structure

The Rubb THA shelter range is robustly designed and is the most versatile of Rubb’s buildings.


THA Rubb shelters are supplied in 9.8ft (3m) modules featuring spans of 19.6ft (6m), 26.2ft (8m), 32.8ft (10m), and 39.3ft (12m) and 10.8ft (3.3m) sidewalls. These shelters can be used as either temporary or permanent site buildings. All shelters are easy to erect by the following methods: your own labor force, Rubb erection team or a Rubb adviser together with your own labor.

The structural steelwork is hot dipped galvanized to the ASTM A-123 standard to protect against corrosion. It is easily bolted together using specially designed Rubb joints which provide the exact pitch and rigidity of the framework. The covering membrane is fabricated from high tenacity PVC polyester fabric which is flame retardant. This is tensioned over the frame. The roof material is typically translucent white and the walls are available in a variety of colors.

The Rubb THA shelter series is not a building code compliant building.
