Ascent™ Step Unit & Up and Over Stairs

Ascent™ Step Unit & Up and Over Stairs provide simple access solutions to complex access issues, including how to get over ducting, pipe work, cable trays, gutters and parapet walls without compromising the health and safety of the worker in line with the Work at Height Regulations (2005).

In developing the Ascent™ step unit range our aim has been to create a standard range of “flat pack step units” in galvanised mild steel. A step unit that is available off the shelf, which will meet all the challenges that you face when creating safe access. 


Step Unit


The Ascent Up and Over Stairs are the result of extensive Research & Development. This investment in both design & manufacturing technology has allowed us to create a step system, flooring, stair treads and handrails for industrial use and manufactured to BS EN ISO 3834-2:2005 and BS EN 1090-1:2009 + A1:2011 & 2:2008 and CE Marked Fabrications. This has produced an accurately manufactured product which is both easy to specify and install.

What We Do

Wherever roof access is required, designers are tasked with creating a safe route to and from the place of work. Following the hierarchy of safety collective protection measures should always be considered above individual fall protection solutions.

D-marc is classed as a form of Collective Demarcation Protection in accordance with the HSE's hierarchy of risk management as set out within the Working at Height Regulations 2005 (WAHR). The WAHR 2005 Part 3 illustrates the use of a demarcation system as an "example of taking other additional suitable and sufficient measures to prevent a fall''. The demarcation system is to be placed a safe distance from the fall hazard (normally >2m). Health and Safety Roofwork HSG33 states that "where work is not done at the edge, demarcation barriers can be provided at a safe distance from the edge (usually at least 2 metres). e.g. work on an air-conditioning unit in the middle of a roof."
