Among the PERI Group—commonly known as PERI—with more than 160 locations worldwide*, this article focuses on the falsework prop products offered by its UK subsidiary, PERI Ltd. Case studies are also included, providing useful reference material for comparison and evaluation.
*As of October 2025
MULTIPROP is an aluminum falsework prop that combines light weight with high load-bearing capacity. It can be used either as a standalone prop or in combination with frames, allowing flexible configurations to suit different site conditions.
Compared with steel props, it is easier to handle, with smooth height adjustment and quick assembly. An integrated measuring scale enables precise adjustment, while the wedge connection system helps reduce installation time.
In addition, features such as a self-cleaning thread and corrosion-resistant coating support long-term use. MULTIPROP is well suited to sites where both safety and efficiency are critical—such as projects with limited manpower, work at height, or falsework for large-span slabs.

The PEP Ergo falsework prop, used to support slab formwork, is a steel falsework prop that offers the high rigidity and load-bearing capacity characteristic of steel. Each prop is designed to withstand loads of up to 50 kN.
It incorporates site-friendly features such as a direction-indicating adjustment nut and an ergonomically designed G-hook that resists snagging, making handling on site safer and more intuitive.
The entire prop is galvanized, providing excellent durability. Even if damage occurs, the inner and outer tubes can be replaced separately, supporting long-term use.
With a wide height adjustment range and markings on the inner tube for easy pre-setting, PEP Ergo improves efficiency on projects where props are used repeatedly.

This case study comes from the construction of the new Banco Ciudad administration building in Buenos Aires, Argentina, designed by London-based architect Norman Foster.
The roof structure covers approximately 9,000 m² and features a wave-like design with complex curved geometry, requiring a falsework system capable of both high precision and high load-bearing performance.
On site, PERI combined its aluminum falsework props MULTIPROP, the PERI UP Flex scaffolding system, and MULTIFLEX beam formwork to create a climbing falsework structure. This solution enabled construction to be carried out efficiently and safely.
This case study comes from the construction of a National Grid power conversion station as part of a UK power infrastructure project. The site required multiple structures of different shapes and scales to be built in parallel, creating a need for a flexible falsework system with high stability.
For the works, PERI’s aluminum falsework props MULTIPROP were installed in a two-tier configuration. These were combined with GT 24 beams and MRK frames to create a safe and efficient support structure.
During implementation, PERI’s technical staff provided on-site guidance, and the PERI UP system was also used as scaffolding and access equipment. This ensured a stable working environment at height, enabling smooth assembly and shorter construction periods.
