Roto Frank Treppen GmbH, formerly known as Columbus Treppen GmbH, has over 60 years of experience in manufacturing loft ladders and staircases. Furthermore, it pioneered the concept of space-saving concertina stairs, for which it is best known. Over the years, Roto Frank Treppen has continued to enhance its manufacturing process; perfectly combining hand-craftsmanship with high precision, state-of-the-art technology. The result is a range of loft ladders, stairs and flat roof access hatches of the highest quality.
Located in Neusäß near Augsburg, Roto Frank Treppen employs more than 80 people and is an independent business unit under the umbrella of Roto Frank AG. The company combines Roto’s experience with precision-engineered window hardware systems and Columbus Treppen’s world-class retractable ladders. The result is a range of high-quality and innovative loft ladders. A great example of this is the Designo wooden loft ladder, which features a high strength folding wooden ladder with a Roto 6-point locking mechanism to create an airtight seal when closed.
As a result of a relationship spanning more than 15 years, Premier Loft Ladders is the main UK distributor for Roto Frank Treppen GmbH. Subsequently, we offer the complete range of Roto / Columbus loft ladders. Also known as the Exklusiv, the Supreme heavy duty loft ladder remains our most popular product. This is a result of it being an extremely versatile loft ladder, which can be specified with a wide range of hatch box and operational options. In addition, the Elite (also referred to as the Junior) is a popular loft ladder. This is because it offers the same high strength and easy-to-use benefits as the Supreme, but is very easy to install and can be fitted within existing hatch boxes. Furthermore, the expanding range of wooden loft ladders, such as the Designo and Quadro, add to the premium product line-up.
