Consultation and Design: Starting with the Client
Every successful project begins with understanding the client’s vision. At Berkeley Engineering, the consultation stage is not a formality — it is the foundation of the entire fabrication process. Our team works closely with clients to discuss their metal fabrication needs, project scope, and operational requirements, ensuring nothing is left to assumption.
During this stage, engineers gather detailed specifications, from material preferences to performance expectations. Advanced tools such as computer aided design (CAD) are used to create models that visualise the outcome and allow for early refinements. This design work is often paired with computer numerical control (CNC) planning, giving our team the ability to map out the precise steps needed to transform sheet metal into finished components or structures.
Clients benefit from transparency throughout this stage. We present design options, highlight potential efficiencies, and provide guidance on where adjustments may reduce costs or improve durability. This collaborative approach ensures that both technical details and practical requirements are aligned before moving forward.
By starting with thorough consultation and robust design planning, Berkeley Engineering sets the stage for reliable, high-quality outcomes. Every decision made at this point carries through to the final product, reinforcing our commitment to delivering tailored custom metal fabrication services that meet exact specifications.
Material Selection: Strength Meets Performance
The choice of material is one of the most critical decisions in any metal fabrication process. At Berkeley Engineering, we recognise that the right selection determines not only the strength of the final product, but also its long-term performance, maintenance requirements, and cost-effectiveness.
For many projects, mild steel remains the workhorse. Its balance of durability, versatility, and affordability makes it ideal for structural components and sheet metal parts across the construction industry and beyond. When greater corrosion resistance is required — such as in food processing, transport, or outdoor applications — stainless steel offers the resilience needed to withstand challenging environments while maintaining a polished finish.
In applications where weight is a concern, such as in the automobile industry or with certain medical devices, carbon steel and alternative alloys provide tailored performance. These materials combine strength with reduced mass, allowing fabricators to deliver efficient solutions without compromising structural integrity.
Our engineers guide clients through these choices by considering factors such as load-bearing capacity, exposure to environmental conditions, and compliance with high quality standards. In some cases, custom steel grades or other materials may be introduced to deliver the most effective balance of performance and value.
By carefully aligning materials to design requirements, Berkeley ensures that each project benefits from the right combination of durability, cost-efficiency, and aesthetic appeal. Material selection is not just about availability; it is about engineering for purpose, reliability, and long-term results.
Cutting and Shaping Sheet Metal
Once the design and materials are finalised, the focus shifts to transforming raw stock into workable forms. At Berkeley Engineering, this is achieved through a combination of advanced methods that ensure sheet metal is cut, shaped, and refined to exact specifications. This stage represents the heart of the sheet metal fabrication process, where precision and efficiency converge.
Modern cutting sheet metal involves multiple technologies. Laser cutting is widely used for its ability to achieve high precision and greater accuracy, creating complex geometries and precise holes in both thin metal sheets and thicker plate. For projects requiring strength without heat distortion, water jet cutting offers clean edges at desired size without compromising material integrity. In applications demanding speed and versatility, plasma cutting provides reliable results across various materials and thicknesses.
Once cut, the material moves into forming operations. Our facility utilises advanced CNC machinery and modern tools to bend, fold, and stamp sheet metal into different forms. Processes such as press braking and the stamping process allow us to create complex parts and sheet metal components that match client expectations for both function and aesthetics.
At this stage, flexibility is key. Berkeley engineers often combine various techniques to achieve the desired shape, whether the project requires body panels for the automobile industry, structural components for the construction industry, or custom solutions for niche applications. By maintaining multiple methods in-house, we reduce reliance on subcontractors and keep tighter control of quality and timelines.
Through disciplined processes and the use of cutting-edge technology, Berkeley ensures each cut and form is delivered with precision, repeatability, and efficiency. This stage lays the foundation for assemblies that not only meet high quality standards but also withstand the demands of real-world use.
Welding and Assembly: From Parts to Structures
With components accurately cut and formed, the next stage in the metal fabrication process is welding and assembly. This is where individual sheet metal parts and metal components are brought together to create durable, functional structures. At Berkeley Engineering, this step is carried out across multiple welding bays, giving our team the capacity to manage projects of varying size and complexity without compromising timelines or quality.
Different projects demand different welding techniques. TIG welding is often selected for stainless steel and thinner materials where precision and clean finishes are essential. MIG and plasma welding provide the speed and versatility required for heavier structural components or large structures. By tailoring the method to the application, we ensure every joint achieves the right balance of strength, appearance, and efficiency.
Beyond welding, assembly plays an equally important role. Projects such as body panels for the automobile industry, custom steel frames for the construction industry, or specialised complex parts for niche applications all require alignment, fitting, and fastening that maintain material integrity. Our engineers work to exact specifications, ensuring assemblies are reliable, consistent, and ready for further processing or finishing.
The integration of advanced CNC machining services with our welding capability also allows us to produce tailored solutions where exact specifications and repeatability are paramount. This combination of technology and expertise ensures that clients receive assemblies that perform in demanding environments while meeting strict high quality standards.
Welding and assembly are more than intermediate steps; they are critical phases that define the durability and performance of the final product. At Berkeley Engineering, every weld is made to last, ensuring the structures we deliver inspire confidence and reliability in service.
Surface Finishing and Treatment
The fabrication of sheet metal components does not end once assemblies are complete. To ensure durability, function, and appearance, surface finishing is a vital stage in Berkeley Engineering’s metal fabrication process. This step enhances resistance to corrosion, improves longevity, and delivers the visual quality clients expect from high quality standards.
One of the most common treatments we employ is powder coating. Applied across sheet metal parts and structural components, powder coating creates a uniform, durable layer that offers both protection and aesthetic appeal. It is particularly effective for custom steel and mild steel projects, where exposure to harsh environments is common. This process also supports effective waste management, as overspray can be collected and reused, reducing material loss and environmental impact.
Other finishing methods include polishing, painting, and specialised coatings tailored to unique industry requirements. For example, clients in the construction industry may require protective coatings that extend service life, while projects in the automobile industry and medical devices often prioritise a clean finish that meets functional and regulatory standards.
Surface treatment also extends into further processing, such as the riveting process or additional machining for complex shapes and different forms. By keeping these capabilities in-house, Berkeley maintains strict oversight of the entire fabrication process, reducing delays and ensuring consistency.
Every project, whether a small batch of sheet metal fabrication services or a large-scale build, receives the same attention to detail. Surface finishing is where both engineering precision and practical experience combine to create a final product that is not only robust but also aligned with the client’s visual and operational expectations.
At Berkeley Engineering, finishing is never an afterthought — it is the stage where excellence is sealed into every job.
Quality Control and Testing
Quality is the measure by which every project is judged, and at Berkeley Engineering it is built into every stage of the metal fabrication process. From the moment raw materials are received through to the handover of the final product, our team ensures that all work meets the strictest high quality standards.
Inspection begins with verifying that sheet metal and steel stock match client specifications for grade, thickness, and integrity. As parts move through cutting, forming, and welding, checks are carried out to confirm dimensional accuracy, correct alignment, and material consistency. Tools such as gauges, non-destructive testing, and stress checks are used to validate both strength and finish.
This structured approach to quality control reduces the risk of defects and eliminates costly rework. It also ensures assemblies maintain material integrity, especially where projects demand high performance under pressure — from structural components in the construction industry to sheet metal parts for the automobile industry or precision medical devices.
Clients benefit from confidence at every stage. By enforcing robust inspection and documentation, Berkeley demonstrates compliance and reliability across all custom metal fabrication services. These checks do more than verify the work; they build trust and reinforce the assurance that the delivered outcome will perform as intended.
At Berkeley Engineering, improved quality control is not an optional extra. It is a core value, woven into the way we fabricate, assemble, and finish. This discipline allows us to consistently deliver projects that align with client expectations while setting a benchmark for excellence in the industry.
