OSI covers any of your construction hardware needs. We bring to the construction industry the experience and technical knowledge necessary to assist in the development, construction, installation and maintenance of any opening access points in new and existing facilities.
The openings must meet an owner's requirements for aesthetic appeal, be cost effective during the life of the facility, provide adequate security to the perimeter of the building and to interior spaces, and allow the uninhibited flow of pedestrian traffic at the appropriate times. And with our fabrication shop, we can custom build any opening to meet your needs.
