Metal spraying provides a proven method for restoring worn components, improving corrosion resistance and extending the service life of industrial assets. GLW Engineering delivers professional metal spraying services for engineering components, structural steel, industrial equipment and fabrication projects throughout the UK. Using advanced thermal spraying techniques, we apply high quality coatings that improve surface performance without affecting the core strength of the material.
Wear, corrosion and surface damage often reduce the performance of valuable equipment. Replacing major components creates significant costs and operational disruption. Metal spraying offers a cost effective alternative by restoring worn surfaces and rebuilding critical dimensions.
The metal spraying process applies molten material onto a prepared surface, creating durable metal coatings that improve wear resistance and corrosion protection. Many industries use metal spraying to extend component life while avoiding the expense of complete replacement.
Thermal spraying remains one of the most widely used restoration techniques because it delivers reliable results across a broad range of industrial applications.
Thermal spray coating systems support engineering, manufacturing, power generation, marine and construction industries. Components exposed to wear, impact, corrosion and high temperatures often benefit from thermal spray coatings.
Thermal spraying allows a coating material to be applied directly to a prepared surface while maintaining the integrity of the substrate beneath. The process creates high quality coatings that improve performance in demanding operating environments.
Many businesses rely on thermal spray coating solutions because they provide long term protection and help reduce maintenance requirements. Additional engineering and restoration services are available through our homepage.
Metal spraying involves applying molten metal or other coating materials onto a surface to improve performance, restore dimensions or provide corrosion protection. The metal spraying process forms part of a wider group of technologies known as thermal spraying.
During thermal spraying, a heat source melts the coating material before it reaches the substrate. Molten particles strike the surface and flatten instantly, forming a continuous coating layer. As the particles flatten and solidify, they mechanically bond to the surface and build the required coating thickness.
Metal spraying supports a broad range of industrial applications because it improves surface properties without altering the structural integrity of the underlying material.
The thermal spray process begins with thorough surface preparation. Contaminants must be removed before metal spraying takes place because surface preparation is critical for coating adhesion.
A prepared surface often undergoes abrasive blasting to create the roughness required for good adhesion. Once prepared, thermal spraying involves directing molten material towards the surface using specialist metal spray equipment.
Different thermal spraying methods use different heat sources and spray materials. Compressed air, compressed gas and fuel gas systems help transport molten particles from the spray gun to the substrate.
The coating process continues until the required coating thickness is achieved. The result is a durable thermal spray coating that enhances corrosion resistance, wear resistance and overall component performance.
Metal spraying offers several advantages across industrial applications.
Corrosion protection remains one of the most common reasons for using thermal spray coatings. Metal spraying protects steel and ferrous materials operating within corrosive environments and harsh outdoor conditions.
Wear resistance improves through the application of specialised spray coatings designed for demanding operating environments. Thermal spray coating systems also provide heat resistance and thermal barriers where components operate at elevated temperatures.
Metal spraying can salvage worn-out parts and restore original dimensions. This creates a cost effective alternative to replacement while helping extend service life.
Thermal spraying also produces minimal heat distortion, making it suitable for many heat-sensitive materials and large structures.
Several thermal spraying methods are available depending on the application and desired properties.
Flame spraying uses fuel gas and oxygen to melt coating materials before application. Wire flame spraying feeds coating material in wire form into the spray process and remains a popular solution for corrosion protection and restoration projects.
Wire arc spraying uses two wires that meet at an electric arc. The electric arc melts the wire tips and compressed air propels the molten particles onto the substrate. Arc spraying commonly applies zinc, aluminium and stainless steel coatings to structural steel and industrial equipment.
Plasma spraying uses a high temperature plasma jet capable of exceeding 10,000°C. Plasma spraying supports applications involving ceramics, refractory materials, tungsten carbide and specialist thermal barrier coatings. The plasma jet allows coating materials with extremely high melting points to be deposited effectively.
High velocity oxygen fuel systems produce high velocity spray particles that create dense HVOF coatings with excellent wear resistance. HVOF coatings often use tungsten carbide and nickel based alloys where demanding service conditions require maximum durability.

Thermal spraying supports a comprehensive range of coating materials. Common metal spray coatings include zinc, aluminium, stainless steel and specialist alloys.
Thermal spray coatings may also use ceramics, plastics, carbide materials and advanced metal alloys. Tungsten carbide coatings provide excellent wear resistance, while nickel based alloys perform well in high temperatures and corrosive environments.
Different coating materials provide unique properties depending on the application. Selecting the correct spray material depends on operating conditions, desired properties and long-term performance requirements.
Metal spraying and paint serve different purposes. Paint provides a decorative finish and a degree of surface protection. Metal spraying creates engineered surface coatings designed to improve corrosion resistance, wear performance and durability.
Many projects combine both systems. Metal spraying often provides corrosion protection before paint systems are applied. This combination helps create long term protection for structural steel, industrial equipment and infrastructure.
The coating process delivers stronger protection than paint alone in many industrial environments.
GLW Engineering combines engineering expertise with extensive experience in metal spraying and thermal spraying technologies. Our team works closely with customers to identify the most suitable thermal spray coating solution for each project.
Every metal spraying project receives careful assessment to ensure the correct coating material, process parameters and surface preparation methods are selected. This approach helps achieve high quality finish standards and reliable long-term performance.
From component restoration to corrosion protection projects, we deliver metal spraying solutions tailored to the demands of each application.
