Industry Leader and Innovator

An industry leader and innovator, Bill O’Keeffe’s designed the first-in-the-industry, deeply serrated square rung for maximum foot traction. Today, O’Keeffe’s continues to be the most specified aluminum ladder manufacturer in the USA. With our years of engineering expertise, we can custom fabricate virtually any type of fixed access, ship, cage or custom ladder you need.

We offer a wide selection of ladder accessories and safety attachments such as safety posts, security doors, fall arrest systems and more that enhance worker safety, protect equipment or meet any project condition.

Utilizing our in-house design and engineering team in combination with our fully integrated computer-aided manufacturing, we can design and fabricate custom platforms, walkways, ramps, catwalks, crossovers, stairs, and more to make sure that you have the right product for your application.

Our ladders are permanently attached to a building or structure in order to offer safe, continuous, and easy access to rooftops, mezzanines, hatches, loading docks, and more. They can also be used to crossover mechanical structures or connect structures together. All of O’Keeffe’s products meet OSHA and ANSI standards to ensure the utmost safety. We also offer fast lead times and competitive pricing for all our products.

Superior Aluminum Building Products

O’Keeffe’s ladders are made with lightweight, high strength aluminum with all stainless steel hardware. Although aluminum is lightweight, it has an excellent strength-to-weight ratio, making it the perfect material for long lasting, maintenance free, commercial and industrial ladder installations.

Because aluminum is corrosion resistant, you have a
durable ladder with low lifetime costs and improved lifetime dependability at the same time. This makes our ladders perfect for outdoor environments where they are exposed to weather or indoor environments exposed to frequent washing and sanitation such as wineries, distilleries, breweries, water treatment plants, food processing facilities, laboratories or other commercial or industrial facilities. They also work great in damp or high humidity settings such as docks, piers, and more.

Aluminum is also non-spark and non-magnetic. When it is struck against itself or other nonferrous metals, aluminum will not spark, reducing the risk of it being a fire hazard. Because it is nonmagnetic, it can be used in places where magnetic equipment is stored.
