Product Description

The conference hall roof project is located in Lome, Togo, which was finished in 2014. The roof adopts dome spatial structure which is a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. The roof panel adopts the sandwich panel.


Product features and advantages

The roof adopts spatial structure which makes the whole weight of the structure very light. Also it does not need to weld on site which speeds up the installation, more important it can guarantee the quality. Considering the conference hall project’s span is more than 30 meters without no column inside it, when the engineers design, they provide the spatial structure roof plan because the spatial structure structure is an economical means of covering large column-free spaces for a variety applications, including sports structures, aircraft hangars, assembly halls, etc.
