H₂S, chlorine and ozone don’t attack GRP resin: no paint or treatment needed.
Every component you need to build your own guard-rails in GRP composite, reinforced with glass fibre: profiles, posts, fixings, connectors and a gate, depending on the mounting type. Unaffected by corrosion and electrically insulating, they are made in Normandy.

Three situations where composite holds up with no paint or treatment.
H₂S, chlorine and ozone don’t attack GRP resin: no paint or treatment needed.
Sea spray and salt don’t attack composite: the guard-rail stays sound, with no repainting.
Non-conductive: the guard-rail can be installed near live equipment with no equipotential bonding on the profiles.
Faced with H₂S, chlorine, ozone or salt, it needs neither paint nor treatment.
No welding: the base plate, posts and profiles are assembled by two people, with no machinery.
Non-conductive: it can be installed near live equipment with no equipotential bonding on the profiles.
