When embarking on a large-scale steel fabrication project, it’s crucial to get your preparations right from the start. This involves first conducting a detailed estimate of the construction cost, which is arguably the most important aspect involved.
This blog outlines the main factors that influence the cost of a steel fabrication project, from costing up, materials to labour, to help you minimise expenses.
1. Materials
You must determine the raw materials required for your project, like steel fabrication. This information is essential for budgeting the costs of custom metal fabrication. Each raw material and its most suitable fabrication process will have significantly different costs.
Next, consider any hardware or accessories that need to be included in the design, such as hydraulic components, gaskets, and so forth, all of which should be included in the total cost.
The quantity of materials and finished products will also affect the price. As with most purchases, the average cost per item usually decreases as the order quantity increases.
2. Labour
Custom steel fabrication demands highly skilled labour, making labour costs the largest part of any metal fabrication project budget. You'll likely require the expertise of designers or structural engineers skilled in CAD/CAM software.
The more agile and streamlined the fabricator's processes are, the more efficient they become, which can lead to substantial cost savings.
Additionally, there is mechanical labour. Specialised equipment and tooling represent a significant capital investment, and steel fabricators incorporate a portion of these costs into each project. Some materials require longer machine time, which must be included in the estimate.
3. Design Complexity
Simply put, the more complex the design, the higher the cost will be. While your plans may appear impressive on paper, their feasibility during production could be a different matter entirely.
This is why it's essential to review plans with a design for manufacturability (DfM) perspective. This approach ensures your plan can be produced according to specifications and remains structurally sound once completed. Moreover, you must account for any necessary specialised machining or prototypes in the cost estimates. Time is money, and if the design requires tight tolerances or intricate features, it will take longer to manufacture, resulting in higher expenses.
4. Painting & Finishing
Subsequently, you'll need to determine if your fabrication project requires painting or a special finish. It's important to understand the costs and design considerations related to the various finishes and specifications available, as well as different types of paint and powder coatings. Similar to fabrication, coating processes might require certification, potentially increasing costs.
5. Quantity
The last piece of the puzzle in calculating steel fabrication costs is quantity. Buying a large number of identical sheet metal parts lowers the cost per unit. Additionally, purchasing raw materials and tools in bulk can lead to discounts. The cost of the templates and equipment needed for production also drops with higher quantities, offering more chances for savings.
