Guardian Splash-Zone Protection Systems
Advanced corrosion protection engineered for the most aggressive zone of marine structures — where tidal action, wave impact, and wet-dry cycling demand the highest performance.
Engineered for the World's Most Aggressive Marine Zone
The splash zone — the region of a marine structure subject to alternating wet and dry conditions — experiences the highest corrosion rates of any marine environment. Guardian Splash-Zone Protection Systems are specifically formulated for this zone, providing outstanding durability and corrosion resistance where conventional coatings fail prematurely.
JST Group supplies and applies Guardian Splash-Zone systems with specialist marine teams experienced in offshore and coastal environments — including platforms, jetties, and marine structures across Southeast Asia and beyond.

Why Splash-Zone Systems?
Purpose-designed for the harshest zone of any marine structure — where impact, abrasion, and continuous wet-dry cycling defeat conventional coatings.
Outstanding Seawater Resistance
Formulated specifically for constant immersion and wet-dry cycling in the marine splash and tidal zones.
High Impact & Abrasion Resistance
Withstands wave action, debris impact, and mechanical loading in the world's harshest marine environments.
Long Service Life
Minimal maintenance requirements — engineered for extended service life even in severe offshore conditions.
Severe Zone Performance
Specifically designed for the most aggressive zone of marine structures — where corrosion rates are highest.
Marine & Offshore Applications
Offshore Platforms
Jacket legs, bracing, and structural nodes in the splash and tidal zones of offshore production platforms.
Jetties & Piles
Marine piling, jetty substructures, and berthing structures exposed to tidal action and seawater.
Marine Steel Structures
Dolphins, dolphins, fenders, and harbour structures exposed to continuous seawater cycling.
FPSOs & Marine Vessels
Hull areas and structural steel on floating production units operating in marine environments.
Six Systems. One Family.
Match the exposure of your asset to the right Guardian splash-zone system — from sheltered harbours (60GW) to exposed offshore platforms (2000) and heavy marine FRP jackets (500), backed by Guardian Petrolatum Primer MP and MT Tape components.
