Hi there, thank you for your question. The door insert is wire mesh to allow for air flow and great rustic aesthetic style. We find the use of wire mesh very practical in this case because of the wet clothes and gear being stored in the lockers.

Hi David, McNICHOLS offers a wide selection of woven and welded Wire Mesh. We often see the product appear in similar applications as what's pictured. You can browse our selection online. Good luck with your project.

Wiremesh in Aluminium is also a cheaper option
