Our sheet metal services capabilities
HLH takes on prototype and production sheet metal services and cutting. We can support one-offs, batch production, welding and assembly as well as stockholding in line with your requirements. HLH's engineers are here to take on challenging complex jobs, be it complex part geometry, specialist materials, extremely tight tolerances or specialist finishing. We have earned our reputation amongst the world's leading companies for high-quality and precision sheet metal services, working on the very latest of technologies.
Waterjet cutting
Our Waterjet Cutting service is ideal for cutting Sheet Metal components between 18mm-40mm.
Bending
Whether you’re after magnetic or hydraulic bending of Sheet Metal components, we’ve got you covered.
Laser cutting
We offer high-precision fibre and CO2 Laser Cutting to produce the most accurate cuts and contours possible to flat metal sheets.
Punching
Punching is a process that combines a punch tool with a bottom die and uses a pressing force to cut part profiles and form metal sheets into specific shapes and patterns.
How Does Sheet Metal Fabrication Work?
Material cutting
The metal sheet is fixed, and then it is precisely cut by the laser cutting machine according to the digital blueprint to obtain the initial shape of the component plate.
Punching and Forming
Using a CNC punch press, complex features such as holes, cavities, and louvers are punched out on the flat surface.
Bending Forming
After the edges are deburred, the part is bent on the bending machine through precise calculation to achieve a three-dimensional structure.
Post-processing and connection
Through secondary operations such as welding, riveting, grinding, painting or electroplating, the final assembly and surface finishing of the parts are achieved.
Advantages of Sheet Metal Processing
The sheet metal processing technology is highly suitable for metal components and can support both prototype design and mass production.
High material utilization
Sheet metal processing extensively uses CAD/CAM software for nesting layout. The software can perform automated and optimized arrangement of multiple different-shaped parts on the entire sheet, minimizing the gaps (waste) between the parts. It is like playing "Tetris" on the entire sheet.
Outstanding production flexibility
The process is particularly suitable for the entire range from rapid prototyping to medium-scale mass production, and can seamlessly and economically achieve scale expansion according to demand.
Rich surface treatment options
Offer a variety of surface treatment processes including anodizing and powder coating, which can meet the diverse needs of products in terms of corrosion prevention, wear resistance, and aesthetics.

Our Sheet Metal Material Options
Aluminum 5052-H32
Aluminum 5052 is a widely used alloy across common part applications made from sheet metal. This popular choice provides superior corrosion resistance, making it ideal for parts exposed to harsh environments. 5052 has a high modulus of elasticity, lending it to formability and weldability, allowing for unique shapes to be created out of the flat sheet. This material is versatile due to high strength, its lightweight nature, and aesthetic characteristics.
Brass C260
Brass C260 is primarily composed of copper and zinc, giving it the golden-yellow color for which it is known. Mechanically, Brass has corrosion-resistant and formable qualities similar to Aluminum 5052. Brass is heavier than aluminum, making it well suited for aesthetic or decorative applications.
Low Carbon Steel CR 1008
Low Carbon Steel 1008 is a mainstay material option in sheet metal fabrication. Containing less than .30% carbon, 1008 is formable, not prone to cracking, and its minimal carbon content provides weldability without the brittleness of a high carbon option. 1008 comes uncoated from the mill and is susceptible to corrosion, however it readily accepts coatings and finishings (such as zinc or powder coat) for protection.
Sheet Metal Finishing Options
Powder Coating Process
Powder coating applies a dry powder to the surface of sheet metal parts. Then, they are cured in a large oven to create a hard finish that is tougher than conventional paint. This process improves durability to parts and adds custom color for aesthetic purposes.
Example of plating on a sheet metal part
Plating (or coating) options can provide corrosion resistance, improve wear properties, and help with conductivity while enhancing appearance with a quality, uniform finish.
