Different Metal Finishing Solutions
Metal components used in industrial, commercial and engineering applications need more 
than good manufacturing. Their surfaces often require additional protection to withstand 
environmental exposure, handling, friction, moisture and corrosion. 
This is where professional metal coating and surface treatment become important. 
Businesses searching for metal coating companies in Sharjah may find several different 
finishing options, including powder coating, plating, passivation, zinc coating and other 
specialized treatments. However, each process serves a different purpose. 
The right treatment depends on factors such as the base metal, component design, operating 
environment, required appearance, corrosion protection requirements and intended 
application. 
Al Sahari Metal Coating provides a range of metal coating and surface finishing solutions for 
industrial and commercial requirements in the UAE. 
What Is Metal Coating? 
Metal coating refers to the application of a protective or functional layer to a metal surface. 
The purpose of coating can vary depending on the application. Some coatings are primarily 
used to improve corrosion resistance, while others are selected for appearance, wear 
resistance, conductivity or surface performance. 
Common metal finishing processes include: 
 Powder coating 
 Zinc plating 
 Zinc flake coating 
 Nickel plating 
 Chrome plating 
 Copper plating 
 Gold plating 
 Silver plating 
 Black oxide 
 Passivation 
 Anodizing 
 Conversion coating 
Because each process has different characteristics, selecting a coating should begin with 
understanding what the component needs to achieve. 
Why Is Metal Coating Important? 
Untreated or inadequately protected metal surfaces can be affected by moisture, chemicals, 
salt, humidity, temperature changes and physical wear. 
A suitable surface treatment can provide an additional protective layer and help improve the 
service performance of a component. 
Depending on the process, metal coating can provide benefits such as: 
Corrosion Protection 
Corrosion can reduce the useful life of metal components and affect their appearance and 
performance. 
Zinc-based coatings, passivation treatments and other surface finishing processes can provide
protection appropriate to particular metals and applications. 
Improved Appearance 
Coatings can also improve the visual appearance of metal products. 
Powder coating, chrome plating, gold plating and other decorative finishes allow businesses 
to achieve specific colours, textures and metallic appearances. 
Better Surface Performance 
Some treatments are selected to improve characteristics such as wear resistance, hardness, 
conductivity or surface compatibility. 
The appropriate process depends on the component and its intended use. 
Choosing Metal Coating Companies in Sharjah 
When comparing metal coating companies in Sharjah, businesses should look beyond the 
quoted price. 
Several factors can affect the quality of the final result. 
1. Understanding of the Base Material 
Different metals respond differently to surface treatments. 
Steel, aluminium, copper, brass and other materials may require different preparation and 
finishing processes. 
A coating provider should understand the substrate before recommending a process. 
2. Surface Preparation 
Surface preparation is an important part of metal finishing. 
Cleaning, degreasing, removal of contaminants and other preparation steps can affect coating 
adhesion and final appearance. 
Poor preparation can result in uneven finishes or reduced coating performance. 
3. Process Selection 
Not every coating is suitable for every application. 
For example, powder coating may be appropriate for certain fabricated metal products, while 
zinc plating may be selected for components requiring a zinc protective layer. 
Similarly, passivation is primarily associated with stainless steel and is used for a different 
purpose from decorative plating. 
4. Quality Control 
Consistent process control helps maintain coating thickness, appearance and surface quality. 
Businesses should consider the supplier's quality procedures when selecting a metal finishing 
partner. 
Passivation in Sharjah 
Passivation in Sharjah is an important surface treatment for suitable stainless steel 
components. 
Stainless steel naturally forms a passive chromium-rich oxide layer that contributes to its 
corrosion resistance. During manufacturing, processes such as machining, grinding, welding 
or handling can introduce contaminants or affect the surface condition. 
Passivation treatments are used to clean and condition the stainless steel surface and support 
the formation of a passive surface. 
The process may be used for components where corrosion resistance and surface cleanliness 
are important. 
Typical applications can include: 
 Industrial components 
 Stainless steel equipment 
 Fabricated parts 
 Engineering components 
 Process equipment 
 Precision components 
The appropriate passivation process depends on the stainless steel grade, component 
condition and application requirements. 
Zinc Plating in Sharjah 
Zinc plating in Sharjah is commonly used as a corrosion-protection treatment for suitable 
steel and iron components. 
During zinc plating, a layer of zinc is deposited onto the component surface. The zinc layer 
acts as a protective coating and can provide sacrificial protection to the underlying steel. 
Zinc plating may be used for: 
 Fasteners 
 Brackets 
 Hardware 
 Automotive components 
 Machinery parts 
 Fabricated components 
 Engineering parts 
The required coating thickness and finishing specification can vary according to the 
component and its operating environment. 
Businesses should discuss these requirements with their coating provider before selecting a 
zinc plating specification. 
Zinc Flake Coating in Sharjah 
Zinc flake coating is another corrosion-protection technology used for suitable metal 
components. 
Unlike conventional electroplated zinc, zinc flake systems use a coating containing zinc and 
aluminium flakes that is applied to the component and cured. 
The process can provide high levels of corrosion protection when correctly specified and 
applied. 
Zinc flake coatings are particularly relevant for components where corrosion performance is 
an important consideration. 
The suitability of zinc flake coating depends on: 
 Base material 
 Component geometry 
 Required corrosion protection 
 Coating thickness 
 Operating environment 
 Required appearance 
 Application requirements 
Businesses searching for zinc flake coating in Sharjah should provide component details 
and performance requirements so that the appropriate coating system can be considered. 
Powder Coating Suppliers in UAE 
Powder coating is one of the widely used finishing methods for suitable metal surfaces. 
During the process, powder particles are applied to a prepared metal surface and then cured 
under controlled heat. 
The curing process forms a continuous coating layer that provides both decorative and 
protective properties. 
Businesses looking for powder coating suppliers in UAE should consider several factors 
before selecting a provider. 
These include: 
 Surface preparation capabilities 
 Available coating colours 
 Texture and gloss options 
 Component dimensions 
 Curing equipment 
 Quality control 
 Application requirements 
 Production capacity 
Powder coating can be used for various applications, including:
