OIS has over 40 years of experience in Ornamental and Architectural metal and glass installation. We take pride in enhancing the NYC skyline with the completion of our advanced Curtainwall installations and specialty metal work.

OIS employs a talented and dedicated union labor force, along with a progressive project management team to successfully complete the most advanced and challenging Curtainwalls, window walls, storefronts and lobbies. We utilize state-of-the-art equipment and installation methods to transform advanced façade designs into successfully completed projects: punctually and cost effectively.

Beginning in 2020 we are pleased to offer off-site “Re-Fabrication” of mis-fabricated materials in our shop located 1-hour outside of Manhattan. We also offer off-site “Re-Glazing of Doors and Facade Panels. We have our own trucking service that can pick up the broken units and return them fully glazed within 3 days utilizing our off-site union trained shop personnel. OIS also specializes in prepping interior and exterior doors for a variety of hardware packages.

OIS Safety

Focus: Making a Living While Preserving a Life

There is nothing more valuable than a human life. We operate in a very dangerous industry and at OIS we take every precaution necessary to protect our employees and the public from potential safety hazards. The health and safety of our employees is of utmost importance to us, therefore we insure that all necessary PPE is worn and that all of our employees obtain the proper Local 580, OSHA and DOB certifications. This is an imperative step in guaranteeing that our employees return home safely after each and every workday. We strive for nothing less than perfection when it comes to jobsite safety, and to mitigate jobsite accidents and injuries we utilize an OIS Safety Marshall on every project. We also organize and exercise daily jobsite work huddles to review all the means and methods of the installation procedures in-order to familiarize the employees of any potential safety hazards.
