The DEFENDER line includes robust, functional, and easy-to-install solutions, available in various configurations to meet specific needs for protection, security, and access control.

• DEFENDER HD PLUS

This mobile fence meets high standards of durability and strength thanks to the special fastening system between vertical and horizontal tubes. Easy to transport due to its 3232 mm length, this model complies with Directive CEE 92/57 D.L.494/96 D.L.528/99. Built with a hot-dip galvanized tubular frame (vertical profiles Ø 40 mm and horizontal Ø 28 mm), it offers resistance and long service life. The mesh, welded within the frame to avoid protrusions, is composed of Ø 2.9 mm horizontal wires (spacing 248.2 mm) and Ø 2.2 mm vertical wires (spacing 110 mm), galvanized to UNI EN 10244-2. The system includes concrete bases measuring 600×235×130 mm, with eight holes for secure panel positioning.

• DEFENDER MARATHON

Directly derived from the DEFENDER HD model. Especially suitable for enclosing work areas and construction sites, it is also convenient for events and sports competitions thanks to its wide visibility. With a height of 1200 mm and length of 3480 mm, it is ideal for temporary enclosures in urban environments. The structure is made of pre-galvanized tubular steel with four Ø 40 mm vertical posts and Ø 30 mm horizontal bars, completed with welded mesh panels with 315×92 mm spacing and Ø 2.8 mm wire. The system is supported by CLS blocks or CLS blocks coated in ABS for added stability and security.

• DEFENDER CITY

A model that gives your project a specific identity and ensures full privacy. Panels can be pre-galvanized or pre-painted in a wide range of colors to meet aesthetic needs or local regulations. At 2000 mm high and 1950 mm wide, the fence features vertical tubes Ø 40 mm and horizontal “U”-profile galvanized tubular bars, completed with corrugated sheet panels available in pre-galvanized or pre-painted versions. The system is also supported by CLS or ABS-coated CLS blocks for enhanced stability.

• DEFENDER PEOPLE

As the result of experience gained in construction site safety, this is a mobile barrier designed to manage pedestrian flows in public spaces. Specifically developed to ensure safety at events—whether sports-related or recreational—this model features a tubular panel that offers excellent visibility for spectators. At 1100 mm in height and 2500 mm in length, it is built with Ø 32 mm pre-galvanized tubular structure with no sharp edges, and panels made from Ø 12 mm welded tubes with 130 mm spacing. Installation is simple thanks to shaped tubular removable feet. Each element is equipped with two welded hooks for series connection.
