LADDER & GUARDRAIL
ENQUIRE
Manufactured with the pultrusion process, the fiberglass reinforced polyester guardrail shapes contain up to 70% glass fibers, guaranteeing extraordinary mechanical properties to the system. The guardrail system is composed of various standard elements: vertical posts, fixing bases, various sections of shapes. The guardrail system is rigorously selected for its chemical resistance to aggressive agents. No additives are used: pure resin possesses an inalterable resistance which ensures a long service life. Chemical inertia is at maximum levels as the composite, which is rich in glass fibers, is protected by an additional synthetic surface veil, that further increases the chemical resistance thanks to the resin rich surface.
