Roof walkway for use on metal roof systems.

The LUX-top® LST – Rail is a well thought-out complete system that combines the function of a walkway with a complete roof walkway and also serves as fall protection. It offers a convenient maintenance route on the roof and reliably protects users from falling – certified to DIN EN 516 and suitable for up to four people at the same time.

Thanks to its clever design, the roof walkway meets all the requirements of modern fall protection systems. The fall protection system can be installed as a fixed walkway on metal roofs with a pitch of up to 15°. It is a type C class K2 walkway (in accordance with DIN EN 516:2006 – with high stability, tested safety and can also be used as a horizontal anchorage device for personal fall protection equipment (PPE).

Why fall protection is essential for metal roofs with regular maintenance work

Permanently installed roof walkways are essential for recurring work on metal roofs – especially for maintenance, cleaning and servicing work. Temporary safety devices such as scaffolding or ladders are costly and do not offer permanent protection.

Only in combination with a suitable safety railing and non-slip walkways can safe working on the roof be guaranteed in the long term. With the LUX-top® LST – Rail you combine all requirements for accessibility, safety and standard-compliant design in one system. This allows you to meet legal requirements and at the same time create a safe working environment for employees or external maintenance personnel.

What risks arise without permanent roof walkways?

On metal roofs without a permanently installed roof walkway, considerable risks arise during maintenance and repair work. Employees or external specialists are forced to use temporary solutions. However, these offer neither permanent protection nor the necessary safety against falling for recurring work, especially as they are erected anew each time, which involves a high risk potential during construction.

A key risk is the increased danger of falling. Even slight roof slopes can be enough for one wrong step to lead to an accident – especially in wet, snowy or dirty conditions. In addition, temporary fall protection systems often do not comply with current legal requirements, meaning that companies can be held liable in the event of an emergency.

In addition, the lack of fixed maintenance routes results in inefficient work processes: Maintenance work takes longer, the installation and removal of temporary fall protection causes recurring costs and extends downtimes. In the long term, this can lead to higher operating costs and even affect the service life of roof systems such as photovoltaic or ventilation systems because maintenance is postponed or not carried out at all for safety reasons.

A permanently installed roof walkway such as the LUX-top® LST – Rail eliminates these risks and enables efficient and plannable maintenance for photovoltaic systems on the roof.

Solutions from LUX-top® – LST – Rail

LUX-top® offers customized fall protection systems that can be optimally installed on industrial metal roofs with a pitch of up to 15° and beyond – without any roof penetration.

The LUX-top® LST – Rail was specially developed for the safe access and use of metal roofs. As a permanently installed roof walkway, it enables maintenance points such as PV systems, ventilation systems or roof drainage to be reached safely. The walkway is non-slip and slip-resistant – even in adverse weather conditions caused by rain, snow, etc. In addition to the metal roof, the roof walkway is also suitable for other roof situations such as roofs with a pitch, i.e. sloping roofs, as well as pitched roofs.

Thanks to the integrated fall protection, no additional rope protection or temporary solution is required. Users attach their PPE directly to the runner of the walkway’s horizontal anchorage device – this saves time and reduces work on site.

It is attached using clamping rails. This allows the walkway to be installed quickly and without penetrating the roof cladding. This protects the waterproofing, prevents leaks and shortens the installation time. Particularly practical: the system is compatible with many common metal roof profiles – ideal for new builds and retrofitting. Thanks to the modular design, it can be flexibly adapted to different roof geometries.

Properties of the LUX-top® LST – Rail

• Tested and certified according to DIN EN 516:2006 (class K2, type C)
• Combination of walkway and horizontal anchorage device in one system
• Suitable for roof pitches up to 15
• Maximum catwalk width: 800 mm
• Post spacing up to 2.50 m
• Can be used by up to 4 people at the same time
• Corrosion-resistant material: aluminum for a long service life
• Installation on metal roof systems with sufficient load-bearing capacity
• Simple, damage-free installation with clamping rails
• Compatible with common metal roof systems (steel or aluminum), depending on
  profile and load-bearing capacity.
• Mounting via clamping rails, suitable accessories available

Another advantage: The LST-Rail can be combined with other safety solutions from LUX-top® – such as guardrails or safety railings – e.g. with:

• LUX-top® FSE 2003 lifeline system
• LUX-top® G-T railing systems for collective side protection
• LUX-top® ASP anchor points

These combinations create holistic safety concepts – individually plannable, economical to implement and permanently reliable. Safe access to technical equipment on metal roofs such as air conditioning systems, antennas or lightning protection systems is also guaranteed at all times with the maintenance route.

Maintenance of PV systems with the LUX-top® LST – Rail

Safe access to the modules is particularly important for buildings with photovoltaic systems. PV systems must be regularly maintained, cleaned and, if necessary, repaired or replaced in order to ensure full performance in the long term. Without a roof walkway, this work is often associated with a high level of risk and incurs additional costs – for example for temporary safety devices and their attachment.

The LUX-top® LST – Rail offers the optimum solution here: the walkway enables safe and non-slip access along the PV system without damaging the roof surface or the modules themselves. Users can secure themselves directly to the integrated horizontal anchorage device with their personal fall protection equipment (PPE). This makes work on the photovoltaic modules on the roof not only more efficient, but also much safer. Walkways provide clearly defined work paths and increase safety on the roof – especially in combination with a continuous railing along the work zone.

Another advantage: as the system is installed without penetrating the roof, the roof waterproofing remains intact – a crucial point for roofs with photovoltaic systems, where leaks must be avoided at all costs. The LUX-top® LST – Rail therefore not only supports occupational safety, but also contributes to the energy efficiency of the PV system.

Installation and maintenance – LUX-top® LST – Rail

Installation is usually carried out by trained specialist partners – for maximum safety and a standard-compliant design. Regular maintenance and user training are also part of the LUX-top® service offering.

The LST – Rail is low-maintenance due to its robust aluminum construction. The construction is corrosion-resistant and resistant to the effects of the weather. Regular visual inspections and recurring inspections in accordance with legal requirements ensure long-term safety.
