Coating Services
From pipeline girth welds to offshore splash zones — Guardian® coating systems manufactured and applied by JST-certified field teams, with full quality documentation.
Guardian Protective Coating Systems
JST Group provides comprehensive coating services using Guardian® Protective Coating Systems — delivering long-term corrosion protection for pipelines, structures, valves, and assets operating in the most demanding environments.
As a Guardian manufacturer, JST Group offers fully turnkey coating solutions — covering product supply, surface preparation, application, and quality control — all managed by experienced in-house teams to international standards.
Our coating capability spans seven Guardian product systems, complemented by specialist in-house workshops, UHP water blasting, and structural repair services for comprehensive asset protection.
- Guardian-certified coating systems
- Turnkey supply & application
- In-house coating services (valves painting, pipe wrapping and PTFE coating)
- UHP water blasting and cleaning services
- Field and workshop application teams
- Marine, onshore, and offshore expertise
- Concrete and composite repair systems
Why Guardian Systems?
Corrosion protection is only as good as the system applied. Guardian products are engineered for extreme environments — self-healing, flexible, moisture-displacing, and proven over decades in the oil & gas, marine, and petrochemical industries.
Guardian systems address the core challenges of:
- Buried and submerged pipeline protection
- Offshore and splash-zone corrosion
- Field joint and girth weld sealing
- Maintenance, repair, and asset life-extension
- Critical joint and connection sealing
Guardian Coating Systems
Seven proven protective systems for every corrosion challenge — from buried pipelines to offshore splash zones.
Guardian Petrolatum Systems
Proven petrolatum-based systems that actively displace moisture and oxygen — ideal for pipelines, valves, flanges, and structural steel in buried and exposed environments.
Guardian Bituwrap Systems
Cost-effective bituminous corrosion protection for buried and submerged steel assets — high resistance to soil stress, moisture penetration, and mechanical damage.
Guardian Butylwrap Systems
Advanced cold-applied butyl-based wraps for aggressive industrial and marine environments — strong adhesion with no heat required.
Guardian Splash-Zone Protection
Engineered for tidal action, wave impact, and wet-dry cycling — superior durability and corrosion resistance in the most aggressive marine conditions.
Guardian Heat Shrink Sleeve Systems
Excellent mechanical strength and corrosion resistance for pipeline girth welds and field joints — suitable for new construction and rehabilitation.
Guardian Visco Elastic Systems
Non-curing, self-healing materials that remain flexible throughout service life — particularly effective for maintenance, repair, and asset life-extension.
Guardian Sealing Systems
Advanced sealing solutions for critical joints, connections, and interfaces — preventing moisture and contaminant ingress at high-risk connection points.
Where We Apply Our Expertise
Guardian coating systems protect assets across the full range of oil & gas, marine, and industrial infrastructure.
Onshore Pipelines
Oil, gas, water, and chemical pipeline networks requiring long-term corrosion prevention.
Offshore Platforms & Jackets
Splash-zone protection, structural steel, and subsea assets in aggressive marine environments.
Storage Tanks & Vessels
External surfaces, bases, undersides, and above-ground storage infrastructure.
Marine Structures
Jetties, piles, harbours, barges, and marine bases exposed to seawater and tidal action.
Valves, Flanges & Fittings
Petrolatum and sealing systems for complex geometries and critical connection points.
Process Facilities
Refineries, petrochemical plants, and process units requiring protective and rehabilitative coatings.
Specialist Coating & Repair Services
Beyond Guardian product supply, JST Group operates dedicated in-house coating workshops and specialist field teams for surface preparation, structural repair, and turnkey project execution — all managed to international quality standards.
In-House Coating
Dedicated workshops with full quality control under international standards — supporting new projects, refurbishment, and maintenance programs.
UHP Water Blasting
Ultra-High Pressure water blasting for safe, efficient, and environmentally responsible surface preparation on live and sensitive assets.
Concrete Repair
Structural restoration systems to protect reinforced concrete from corrosion, chemicals, and environmental exposure — onshore and offshore.
Composite Repair
Non-metallic, high-strength repair for pipelines and structures requiring reinforcement without hot work or shutdowns — suitable for live systems.
