OSI brings decades of experience and a customer focused approach to your projects.
O.S. Interior Systems incorporated in 1972. We built our business on a simple approach: safety first, maintain a low overhead and flexibility. Our company performs as a competitive subcontractor in the multiple roles of Gypsum Board Systems, Relocatable Partitions, Acoustical Ceilings, and other types of Architectural Finishes. We are among the largest specialty contractors in Texas and the largest installers of the Gravity Lock Wall System in the USA.
Obvious advantages to having your own architectural work force include: schedule control (we can call in our own cavalry and do not need to persuade some other sub to do so), quality control, and cost control, in addition to many others. We maintain on our payroll a staff of over 120 skilled workers. These field workers are in addition to our Superintendents, Project Managers and support staff.
