Polimpianti, a new roller for pool covers

Polimpianti is bringing innovation in the pool market and it's glad to introduce the new structural PULTRUDED roller. An innovative product that replaces standard materials (aluminium, stainless steel Aisi 304 and Aisi 316L) that are commonly used for winding devices and pool covers. Such material guarantees maximum corrosion resistance (chlorine gas and water treatment systems by electrolysis), while keeping its mechanical resistance unaltered (like stailness steel). Thus it is used to avoid pitting and stress corrosion cracking that often affect pools where winding systems are subject to considerable environmental conditioning (e.g. temperature variation, constant use of chemical products, poor ventilation …). Thanks to their structure, these pipes are easily workable (they can be cut, milled, drilled, rectified) and they can be glued. Connection elements made from composite materials can also be provided to preserve the overall uniformity of the whole set (internal structural backing). Discover technical feature:
