For construction or industry purposes, access to higher-positioned work places can be achieved with PERI system scaffolding. The target group is people working in construction or industry who usually wear work clothes and protective equipment. The two systems PERI UP EASY and PERI UP FLEX can be flexibly combined and so cover a huge range of applications.
Also access to public areas can be implemented with the systems.
In addition to the special connection technology, PERI UP scaffolding technology offers consistent metric grid dimensions: all PERI UP system components such as standards, ledgers and decks are available in length grid arrangements of 25 cm or 50 cm. The system and decking widths also take into consideration the metre as a base unit.
PERI UP Flex usually uses 25-cm-wide steel decks with lengths from 50 cm to 300 cm for all applications from shoring over different types of work scaffolds to access solutions. PERI UP Easy Frame is available as façade scaffolding with system widths of 67 cm and 100 cm; depending on the width, both combi decks with a width of 67 cm as well as steel decks with widths of 33 cm or 25 cm can be used.
Since also the height dimensions of PERI UP Flex and PERI UP Easy are identical, the possibilities for combining them both also horizontally are almost unlimited.
With PERI UP scaffolding technology, a minimum number of system components can be used to realize a previously not feasible range of applications. Rosett nodes are integrated on the vertical system components onto which horizontal components can be directly connected without requiring any couplers. This connection technology is not only fast and safe, it also underlines the boundaries between frame and modular scaffolding.
The connection on the PERI UP Ledger is in the form of a wedge which is hooked into the rosette opening. Thereby, the securing wedge drops into the rosette opening due to its own weight and locks automatically. The wedge is then secured in position with one blow of a hammer.
All PERI UP decks have integrated protection against lifting (Locking Deck): the clamp on the deck engages the rectangular ledger without requiring any additional measures. PERI UP decks are thus secured in position after installation without additional components as well as being secured against lifting. If required, individual decks can be subsequently removed, e.g. for bringing in materials.
Ledgers can be directly connected to the rosette nodes of the PERI UP Standards as well as the PERI UP Easy Frame. Thereby, for example, PERI UP Flex Stairs with 75 cm widths can be connected to the frame scaffolding without any additional frame columns or couplers. The transition from the stairs to the scaffold bay is covered without leaving any gaps, therefore no gap covering is required.
Through the integrated scaffold node on the Easy Frame, PERI UP Easy can be combined with PERI UP Flex Modular Scaffolding. Thus, for example, brackets as well as ledgers for the erection of prefabricated stairs can be quickly connected without requiring any accessories.
On high and slender elements such as columns or chimneys, vertical ladder access is the most inexpensive solution.
In sections of approx. 2.00 m, the ladders are connected to the scaffolding. The clampable ladder safety cage provides site personnel with very safe conditions for climbing up and down.
With vertical ladder access, large heights can be reached in the shortest way – however, without the possibility of transporting materials at the same time.
Scaffold users often have to change working levels within the scaffolding itself. Hatches and access decks allow site personnel to safely reach the scaffolding level above or below.
Hatches consist of a frame with access opening and short decking piece as well as an attached ladder. If hatches are used inside containers, often only small manholes (approx. 55 cm or 22 inches) are available for material transport. Hatches are also a suitable solution for short bay lengths.
The access deck consists of a hatch that functions as an access opening which is integrated in a longer deck, as well as an attached ladder. The hatch can be opened for climbing through and then closed again afterwards. When closed, the hatches and access decks can be used as working areas.
For facade working scaffolds, access decks and ladders connect the different working levels. These means of access are the easiest and fastest to mount of all possibilities as well as being especially cost-effective.
Access decks with ladders are available in lengths of 2.50 m and 3.00 m which allows the integrated ladders to be folded up under the deck when not in use. If the integrated ladder is folded upwards and the hatch closed, the complete width of the scaffolding can then be used. If the facade scaffolding is particularly long, then access decks with ladders can be installed approx. every 20 m in order to reduce walking distances.
Alternatively, access decks with separate hook-in ladders can be used. For the PERI UP Easy Frame Scaffolding, access decks and access decks with ladder are available with a width of 67 cm.
The staircase units have the grid dimensions of the PERI UP Flex Scaffold and provide a high level of flexibility along with all the advantages of modular scaffolding. The 75 cm wide staircases serve as access means to working areas or construction sites, and reach heights of up to 90 m.
All decking widths as well as the PERI UP Flex Staircase 75 match the grid dimensions of the standards and ledgers (25 cm or 50 cm). These are mounted on UH Ledgers. All this results in a high degree of flexibility regarding scaffold adjustment.
Height adjustments to building openings are carried out independently of the floor heights by means of brackets and short flights of stairs (1.50 m long, 50 cm/100 cm high).

Height adjustments take place by means of the laterally mounted brackets. As a result, the stair tower floor height of 2 m remains constant over the entire height which simplifies planning and assembly.
For stabilising the brackets, installation of a few additional components in the stair tower is sufficient. Additional anchors are not necessary.
With the “ledger-to-stair” which is attached on a step, height adjustments up to 50 cm can be created by means of industrial decking as a ramp.
Smaller height adjustments are carried out using ramps with industrial decking, whereby the rectangular profile for fixing the decks through the “ledgerto-stair” procedure is mounted on a step.
With the stairwell staircases, compact access means can be provided on the inside of buildings with small staircase wells. At the same time, the stairs serve as working platforms for carrying out further work on the sides of the walls.
The staircase units have the grid dimensions of the PERI UP Flex Modular Scaffold and offer the required adaptability of stairs to suit small areas and narrow geometries.
With standard components, accesses can be created to all floors using height increments of 25 cm. Standard configurations are available for the common floor height of 2.75 m.
PERI UP Stair Towers are particularly fast and cost-effective to install if the standards are tightly connected to each other and complete stair sections are moved with the crane.
Suspended stairways can also be used for accessing climbing formwork or in shafts, e.g. subway construction. The standards are tightly connected by means of bolts and nuts whereby each connection can transfer up to 19.7 kN permissible tension force. Theoretically, this means up to 40 scaffolding levels can be installed as suspended scaffold.
In general, staircases are erected in front of or in a building and connect the ground with different levels of the building. The fact that staircases on the construction site can be used completely differently is shown by the examples on this page.
With climbing formwork, climbing brackets can be used as a base for the stair tower. This means they are not dependent on any foundation measures on the ground and can connect finishing platforms with different floors of the building.
The PERI UP Flex Staircase 100 is erected as a 10-leg tower complete with separate landings, and used on construction sites with high requirements regarding loads and accessibility.
With a step width of 100 cm, the stair tower provides easy and comfortable access – with sufficient space for site personnel to pass each other. With a permissible load of 3.0 kN/m², it can be assembled up to a height of 50 m. Assembly is simple and fast without requiring any tools: the stringers are mounted first, followed by the steps which interlock during installation. The top step secures all the others.

Besides a safe transfer of loads, slip resistance is an important requirement for all stairs. The steps of the PERI UP Flex Staircase 100 are perforated like the UDG Decks. The trumpet-shaped openings are bent upwards and are safe to use even with oil-smeared shoes. With an additional edge profile on the ledgers at the start of the stairs, the upper corner is also slip resistant.
The possibility of small objects falling to the ground is also prevented: the steps are fitted with closed webs while toe boards along the landing edges provide an additional safety feature.
The flights of stairs of the PERI UP Flex Staircase 125 differ from the PERI UP Flex Staircase 100 only through the wider steps; all other components are the same. The maximum height of the stairs in the standard configuration is limited to 40 m due to the larger areas for the live loads.
With step widths of 125 cm, the clear width of 120 cm between the legs that is required in some countries is fulfilled. Based on the average shoulder width of 60 cm, convenient and comfortable passing on the stairs is possible. Using this staircase is both practical and sensible on those construction sites where the stairs are in frequent use by the workers.
