In 2008, The Purling Mill company started officially; it was the family’s own business from Hubbard. They
were motivated by steel manufacturing and infrastructure, joining the field of millers in world
innovation and competition, mostly specializing in high-quality steel metal for building, targeting large
and small institutions for infrastructure. They manufacture structural components such as Z Purlins, C
Purlins, girts, and metal building accessories.

Z Purlins are structured components with a Z shape, which allows adjacency to purling at overlapping joints. It helps in increasing strength and stiffness. Reducing additional support for the structure and
adding firmness and flexibility to the building to achieve the objectives. The Purlins Mill company has
come up with Z Purlins, which are preferred for roofing in large industrial, commercial, or agricultural
buildings where long spans and continuous support are needed.

Generally, Z Purlins are more expensive per unit square due to the complexity of the shape, but most of
the big industrial institutions prefer them. Less human labor is used in building and infrastructure while
using them. One of the advantages of using them is that they are stronger for continuous spans for large
buildings; their disadvantages are that they are slightly more complex to manufacture and align during
installation.

Contrarily, The Purlin Mill is working to bridge the gap between the big industrial institution and smaller
institutions in the society by introducing C Purlins, which are commonly used to construct smaller
structural buildings such as sheds and garages. They use shorter spans; they do not overlap. However,
continuous spans are not required in the infrastructure. The best part about C-purlins is that they are
easy to install for small construction and also seem to be cheap due to smaller projects not requiring
continuous spans. One of the advantages is simple installation in small building projects; its
disadvantage is that it is less efficient for long spans.
