Domestic Flooring
Hopleys Open Web Steel Joists® light weight galvanised open web joists are ideal for domestic flooring applications. They are suitable for both subfloor and particularly first floor applications because of their light weight and easy installation.
They also make fitting for pass through services, such as electrical wiring and plumbing, extremely easy.
They offer a flat surface, good load bearing characteristics and high durability. Our light weight joists reduce flooring dead loads which in turn reduces the size of the supporting members and lowers overall costs.
They allow larger spans, reducing stump and bearer costs and installation time.
Please note: If you are not familiar with Bearer Span Tables or if you need further information please contact your Hopley's Representitive for clarification.
