OUR WORKS
Metal Work Services
At Choong Ngai Engineering, we provide professional custom metal fabrication in Malaysia, specialising in precision custom metal parts, stainless steel custom made solutions, and custom metal work tailored to diverse industries. Our expertise covers a full range of services, including metal rolling, metal shaping, plate rolling, metal bending, and welding services in Malaysia. With a focus on accuracy and durability, we deliver high-quality metal products that meet exact client specifications and support both small-scale and large-scale projects.
What Are the Common Ways of Stainless Steel Welding?
Stainless steel retains its corrosion resistance only when heat is controlled. Improper welding can weaken the material and reduce durability.
Fabricators rely on 3 proven welding methods. Each method suits different thicknesses, load demands, and finish requirements. These techniques form the foundation of our metal welding services that Malaysian manufacturers trust.
a) TIG welding
TIG welding uses a non-consumable tungsten electrode and an inert shielding gas. It creates clean, precise welds with minimal spatter.
This method offers superior control over heat input, making it ideal for thin stainless steel and cosmetic joints.
TIG welding is commonly used for:
- Food-grade stainless steel equipment
- Pharmaceutical piping systems
- Architectural metal features
- Custom stainless steel enclosures.
When appearance and corrosion resistance matter most, TIG welding delivers the highest finish quality.
b) Resistance or Spot Welding
Spot welding joins metal sheets using pressure and electrical current. Heat is generated only at the contact point, creating a fast and efficient bond.
No filler wire is required. This makes the process economical for high-volume custom sheet metal fabrication.
Spot welding is commonly used for:
- Sheet metal assemblies
- Automotive components
- Wire mesh products
- Lightweight stainless steel frames.
It is best suited for thin materials where speed and repeatability are key.
c) MIG welding
MIG welding feeds a consumable wire that melts to form the weld joint. A shielding gas protects the weld pool from contamination.
It is faster than TIG and suitable for medium to thick stainless steel sections.
MIG welding is ideal for:
- Structural frames
- Industrial tanks
- Heavy-duty brackets
- Large, custom made stainless steel projects in Malaysia.
For strength-driven applications where efficiency matters, MIG welding offers a reliable balance of speed and structural integrity.
What is a Turning Service in Metal Fabrication?
Turning uses a lathe to rotate a work-piece at high speed while a cutting tool removes material. The process produces cylindrical custom metal parts with high accuracy.
Typical turning applications include:
- Shafts and pins
- Bushings and spacers
- Threaded rods
- Precision machine components.
Our CNC turning service delivers tight tolerances and repeatable quality for both prototypes and production runs.
For companies seeking dependable production of custom metal parts in Malaysia, turning is a core process.
What is a Milling Service in Metal Fabrication?
Milling shapes metal using a rotating cutting tool while the workpiece remains fixed or moves along a CNC table. It creates flat surfaces, slots, pockets, and complex contours.
Milling is commonly used for:
- Mounting brackets
- Gear housings
- Base plates
- Custom mechanical components.
CNC milling is essential for multi-axis precision and tight dimensional control.
When required, our metal bending services complement milling by forming accurate angles and curved profiles that align perfectly with machined features.

Frequently Asked Questions
What Is Custom Metal Fabrication, and How Is It Different from Standard Metal Parts Production?
Custom metal fabrication involves producing metal components based on specific client drawings and technical requirements.
Unlike standard mass-produced parts, custom fabrication delivers exact dimensions, selected materials, and tighter tolerances for specialised applications.
This ensures better fit, performance, and reliability for industrial systems that cannot rely on off-the-shelf components.
Can Choong Ngai Fabricate Stainless-Steel Parts Custom Made in Malaysia for Industries That Need Corrosion-Resistance?
Yes. We fabricate stainless steel custom made components in Malaysia for environments that require corrosion resistance and durability.
Our services cover machining, welding, forming, and finishing for industries such as food processing, water treatment, marine, and manufacturing.
Surface treatments like passivation and polishing help extend service life in demanding conditions.
Which Welding Services Do You Provide and Which Weld Method Is Best for My Project?
We provide TIG, MIG, spot, flux-cored, and stick welding services in Malaysia.
The right welding method depends on material type, thickness, structural load, and finish requirements.
After reviewing your drawings, we recommend the most suitable and cost-effective welding process for your project.
How Long Will Fabrication Take, and What Affects the Lead Time?
Lead time for custom metal work in Malaysia depends on project size and complexity. Simple parts may take about 5 working days, while larger assemblies may require several weeks.
Material availability, machining difficulty, welding volume, finishing, and order quantity all affect the schedule.
Clear drawings and early approval help speed up production.
What Is the Difference Between Metal Shaping, Metal Bending, and Plate Rolling?
Metal shaping services refer to processes that change the form of metal.
Metal bending services create precise angles using press brakes, suitable for brackets and frames.
Plate rolling services form cylinders or cones, commonly used for tanks and curved structures.
