The marine industry requires high-precision, corrosion-resistant components that can withstand harsh ocean environments, extreme temperatures, and constant exposure to moisture and salt water. As a trusted partner in marine manufacturing, JR Gilbert Engineering provides high-quality CNC machining solutions for shipbuilding, offshore structures, propulsion systems, and marine equipment manufacturers.

With over 40 years of experience in precision machining, we specialise in precision marine engineering, delivering durable and reliable components that meet the strict performance requirements of the marine, naval, and offshore industries. Our ISO 9001-accredited facility ensures every part we produce adheres to the highest standards of quality, strength, and corrosion resistance.

1. Corrosion-Resistant Materials For Harsh Environments

Marine components must be able to resist rust, saltwater corrosion, and extreme weather conditions. As an experienced marine parts manufacturer, we machine a variety of marine-grade materials, including:

Stainless steel (316, 304, duplex stainless) – High-strength and corrosion-resistant, used in propeller shafts, pump housings, and marine fasteners.
Bronze and brass – Preferred for bushings, bearings, and seawater-exposed components due to their natural corrosion resistance.
Aluminium – Lightweight yet strong, commonly used for housings, structural brackets, and marine enclosures.
Plastics (PEEK, PTFE, Acetal) – Ideal for sealing components, insulation, and wear-resistant parts in marine applications.

2. Precision Machining For Critical Marine Components

Marine vessels and offshore structures require tight-tolerance machined components to ensure seamless operation and reliability in extreme conditions. Our precision marine engineering expertise enables us to manufacture:

Hydraulic and fluid-handling components – Custom-machined pump housings, valve bodies, and pressure fittings.
Structural and framework components – Brackets, plates, and support structures used in shipbuilding and offshore platforms.
Navigation and electronic system enclosures – Durable housings for marine electronics, radar, and communication systems.

3. Marine Fabrication And Engineering

In addition to precision machining, we offer marine fabrication and engineering services to produce custom-welded assemblies, support structures, and marine-grade metal fabrications. Our in-house welding and fabrication capabilities allow us to provide complete solutions for marine equipment manufacturers, ensuring strong, high-quality components built for the toughest conditions.

4. Full Finishing Services For Marine Components

To further enhance corrosion resistance and durability, we offer comprehensive finishing services, including:

Anodising – Protects aluminium components from corrosion.
Hardening & heat treatment – Increases strength and wear resistance for high-load marine parts.
Powder coating & wet painting – Provides long-lasting protection against salt water and harsh weather.
Zinc plating & galvanising – Essential for marine fasteners, brackets, and steel components exposed to seawater.

5. On-Time Delivery & Reliable Supply Chain

We understand that delays in marine manufacturing can hold up vessel repairs, offshore projects, or shipbuilding timelines. Our shift-based production system ensures we deliver parts on time, whether for one-off prototypes, spare parts, or full-scale production orders.
