Loft Conversion Steel Calculations

At CivilWeb Consulting Engineers we have been completing loft conversion steel calculations for many years. This page is dedicated to our loft conversion steel calculation services, we have other pages including extensions, internal openings and roof support beams on our Steel Beam Calculations for Building Control page.

On this page we have the details for the design of steel purlins to support the roof for loft conversions. Loft conversion projects also often include steel ridge beams to support the roof and steel beams to support the new flooring. Details for these calculation packages can be found on our Ridge Beam Calculations and our RSJ Calculations for floor supporting beams pages.
