Our Process - 4 Simple Steps
Step 1 - Consultation
We conduct an in-depth consultation to understand your needs, preferences, and vision. This helps us create a clear plan based on your input, whether it’s a detailed brief or a simple sketch, ensuring we align with your desired outcome.
Step 2 – Design
Using advanced 3D modelling and CAD software, we create a detailed model for review and feedback. After incorporating changes, we perform structural checks, produce site and yard drawings, and finalise fabrication plans once approved.
Step 3 – Fabrication
Our skilled team employs cutting-edge welding and machining techniques to fabricate your project. We handle steel, stainless steel, and aluminium fabrication in our Wickford factory, with on-site metalwork and mobile welding available as needed.
