Thanks to the shape of the spiral, its installation does not require any type of complex work, can also be installed in walls, nets and other vulnerable areas.
The design of the concertina, provided with high resistance blades, has a great capacity of penetration and impact, producing a deterrent effect on potential intruders.
All phases of the manufacturing and installation process, as well as the life cycle of a product, are decisively influenced by its design. Our products are specifically designed to be corrosion-resistant and to ensure a higher level of security, without forgetting about the aesthetics.
As an option, you may want to incorporate several strands of barbed wire into all of these products, for installations which require an especially high level of security. The poles are equipped with a zipper for the longitudinal mounting of accessories as well as all necessary clips to withstand the tension of the wires.
All our steels are manufactured according to the provisions and procedures of the Spanish Basic Document on Structural Safety, and all procedures are designed to fulfill the specific conditions included therein.
