Cylindrical helical springs made from rectangular and square section wire and bar. Guide to calculation and design - Compression springs Ingestion-build-93833 a) in the following cases1 Scope This British Standard provides guidance on the design of parallel sided helical compression springs manufactured from rectangular and square section wire and bar. This standard applies only to springs made from rectangular section material where the ratio of radial dimension, b, to the axial dimension, h, termed the shape factor, m, is not greater than 2. 5 and not less than 0. 4. NOTE 1 This applies because, outside the shape factor range 2.
