FAQs
Steel Installation in Horley: FAQs
Do you provide steel installation across all of Horley?
Yes, we cover the RH6 postcode area in full, including Massetts, Lonsdale, Smallfield, Horley Row, Westvale Park.
How is a steel beam sized for my opening?
A structural engineer calculates the required beam size and type based on the span of the opening and the load it needs to carry — including the floor or roof structure above and any additional loads such as water tanks. This is confirmed before ordering the steel.
Can a steel beam be installed without removing the whole wall?
Often yes — a beam can be installed to widen an existing opening or doorway rather than removing an entire wall, with the remaining sections of wall providing the bearing for the steel.
Does living near Gatwick Airport affect planning permission in Horley?
