Innovative in terms of technology and performance, ALU - TECH is the first extruded aluminium manhole cover. Light and easy to handle, it allows exceptional watertightness and great mechanical resistance.
With a modern and elegant design, ALU - TECH has been designed with a frame to contain the special EPDM rubber seals which, stressed by being anchored to the base via the four fixing points, make the product truly unique. The standard kit includes four lifting handles and an Allen key to make it easier to install and re-secure the base in the frame.

RING is Baldassar's patented fixing system that allows the fences to be installed in just a few minutes in a unique and economical way. RING is fixed directly to the wooden pole sunk into the ground, or to the screwed-in or screwed-on support, and thanks to its fixing system it allows you to hook the fence panel directly in a safe, permanent and above all fast way.
RING can be used for areas to be secured (such as an embankment fencing in pedestrian areas) but it is also widely used in residential contexts.
