Decoding Structural Steel Framing Systems: BNS Groundwork London Insights

Skeleton Steel Framing

For some of our steelworks, buildings require a skeleton steel frame. This is composed of steel beams and columns connected using proper connections. For this, our contractors use steel beams around the perimeter of the structure, termed as spandrel beams, where any masonry walls should be placed.

Wall Bearing Steel Framing

Where structural steelwork building involves a wall bearing steel framing structure, a building wall (whether interior or exterior) is used to carry the end of structural members that support floor or roof loads. Our contractors ensure that the wall bearing is strong enough to both carry vertical reactions and resist imposed horizontal loads.

Long Span Steel Framing

Long span steel framing is what our contractors consider when large clearance is required, meaning that long spanning cannot be realized using steel beams and columns. Long span steel framing structural steelwork options offer options, for instance, girders, trusses, rigid frames, arches and cantilever suspension spans.
