At Sentry Steel Inc our mission is to continuously raise the bar to achieve the highest quality services in custom structural and miscellaneous steel fabrication and erection.


Yokomori partnered with U.S-based Sentry Steel Inc in 2017

Yokomori is proud to offer its stair systems in the United States. Yokomori is a family-owned company based in Tokyo, Japan. Yokomori has provided the building industry with innovative products for over 70 years. When you choose Yokomori stairs for your project, you will benefit from decades of experience and perspective that is unmatched anywhere in the world.

Yokomori's broad experience in the construction industry, combined with our constant pursuit of perfection, has rewarded us well. Of the commercial buildings built in Japan over the last 70 years, 85% are outfitted with Yokomori Precision Stairs.

At Yokomori, we believe that stair assemblies are an integral part of a successful building design. We've spent decades investing in robust manufacturing technologies and a skilled team of engineers, designers and craftsmen to guarantee that every tread and every stringer with the Yokomori name will exceed expectations.
