Multi-storey buildings with application of open web steel joists are very common for economical construction. Open web steel joists span between
the primary framing members of the structure. Open web steel joists have long been used both as mezzanine joists in multi-storey buildings and as roof secondary members supporting roof sheeting panels and built-up roofs.

Steel is incredibly durable and requires minimal maintenance over the lifetime of a building. This saves money in the long term and means that each building is built to last.
