It is no secret that structural steel fabrication requires many steps to create the finished product. However, many fabricators may not know all the steps involved or the proper order to complete them. So, let's get started! This blog post will outline the main stages of a structural steel fabrication process and explain their importance. We will also discuss some key points to consider during the fabrication process.
What is Structural Steel Fabrication?
Structural steel fabrication is the process of constructing or reconstructing metal structures with steel. This fabrication process basically consists of cutting, bending, and assembling the fabricated steel. This can be done for various purposes, including building bridges, housing, factories, and other large structures.

There are many reasons why structural steel is the material of choice for industrial construction. Steel is incredibly strong, highly resistant to heat, easy to fabricate, and extremely durable, making it an ideal choice for factories and warehouses.
Main Steps of Structural Steel Fabrication Process

Now that we have a basic understanding of structural steel fabrication let's look at the main steps involved in the process.

1. Design Preparation:
The first step in any structural steel fabrication process is design preparation. This is where the drawings and specifications for the project are created and agreed. Once the design is complete, the draftsman can start creating exact Bill of Material (BOM) and Bill of operations (BOO) to prepare the information needed for purchase and production.

2. Material Acquisition:
When draftman finishes detailed BOM then purchases will take it over to acquire the required materials for the project. This usually involves ordering the steel from a supplier. Steel can be in standard length or already cut in to length based on order. The steel will then be delivered to the fabrication site.

3. Steel Cutting and Drilling:
The next step is to cut and drill the steel. This is usually done with a CNC machine. The steel is first cut to the correct length and then drilled to create the holes needed for the project. Steel cutting can be performed by circular saw machines, laser cutting machines, waterjet machines, or plasma cutting machines.

4. Bending and welding:
Once the steel is cut and drilled, it is time to bend and weld it. Various bending processes such as section bending, roll bending, plate bending, and tube bending are performed to create the desired shape. The steel is then welded together using either MMA welding or MAG welding. The welding can be performed by hand or with a machine. Welding must be performed under strict quality management conditions as per BS EN ISO 3834, under the supervision of a welding coordinator.

5. Quality Check:
The quality check ensures that the steel meets all the required specifications. It includes visual inspections, dimensional inspections, and mechanical tests. Non-destructive testing (NBT) is also performed to ensure that the welded parts are free from hidden defects and cracks.

6. Finishing:
After the quality check is complete, the steel is then sandblasted and painted. This is done to protect the steel from corrosion. The finishing process is performed before installation to reduce the installation time and cost.

7. Delivery, Assembly, and Installation:
In the final step, the steel is delivered to the site and assembled as per the required design. The assembly process usually involves bolting, riveting, or welding the steel parts together. The fabricated steel parts must be handled carefully to avoid any damage. Installation can be performed by using heavy-duty cranes. BCSA (The British Constructional Steelwork Association) has published several guides on structural steelwork installation and safety measures.

The steel structural fabrication process can be completed by following all these steps.
Key Points to Consider during the Structural Steel Fabrication Process

Structural steel fabrication requires a high degree of skill and precision, as even a tiny error can jeopardize the structure's safety. As our world becomes increasingly industrialized, the demand for fabricated steel structures will continue to grow. Here are some key points to consider during the structure steel fabrication process:
    By developing a thorough plan, structural steel fabricators can ensure that their projects are successful.
    Project Planning

    The first thing to consider in any fabrication project is to create a detailed plan. This plan will include a blueprint of the final product and a schedule and budget. Completing a project on time and within budget would be impossible without a well-designed plan. In addition, the plan helps to ensure that all aspects of the fabrication process are considered. For example, the plans for a bridge will take into consideration the weight and type of traffic that will be using the structure.
    Understanding the Customer's Requirements

    In order to meet the customer's expectations, it is essential to understand their requirements. This includes understanding the purpose of the structure, as well as the load-bearing capacity and environmental conditions. By taking the time to understand the customer's needs, fabricators can create a structure that will meet their expectations. Efficient communication and a professional team are essential to ensure customer needs are met.

    To avoid any inconvenience, it's better to share your developed design with the customer for approval. Also, get their feedback during each stage of the manufacturing process to ensure your customer satisfaction.
    Analyze your Capabilities

    One of the most important key points to consider during your steel structure manufacturing project is to analyze your company's capabilities. You should consider your company's strengths and weaknesses and the available resources. This can be done by conducting a SWOT analysis. Here are some of the critical factors that you should consider while analyzing your company's capabilities:

    • Does your company have the necessary resources to complete the project?

    • Do you have the required expertise and experience to fabricate the structure?

    • What are your company's core competencies?

    • Do you have a good understanding of the market and the competition?

    • What are your company's financial resources?

    After analyzing your company's capabilities, you should make a list of the resources that are required to complete the project. This will help you understand the project's cost and whether or not your company can achieve it.
    It would be best if you considered a certified vendor for your various needs.
    Shortlisting Vendors

    Once you are done analyzing your company's capabilities, you should have a good idea of the resources required to complete the project. The next step is to shortlist vendors who can provide you with the necessary materials.

    The vendor must hold relevant certifications from authorities such as the American Institute of Steel Construction (AISC), American Welding Society (AWS), International Organization for Standardization (ISO), and the National Institute of Certification in Engineering Technologies (NICET). They should also be able to provide you with the necessary resources promptly.
    Analyzing Project Progress

    It is essential to monitor the project's progress at every step closely. This includes understanding each task's status and the resources being used. You can identify potential problems by analyzing the project's progress and taking corrective action. This can be done by proper reporting from shop floors. The reporting process is divided into three steps:

    • Report project % by foreman:
    The project manager or foreman should fill out this report. It includes a list of all the tasks that have been completed, as well as the percentage of work that has been completed. It helps identify which tasks are behind schedule and on track. This report also helps to understand the project's overall progress.

    • Reporting by the workers on the shop floor:
    In a typical structural steel fabrication company, the shop floor is where the bulk of the work takes place. It's a busy, sometimes chaotic environment, and it's important for workers to be able to report on what's going on efficiently and effectively.

    There are several ways to do this, but one of the most popular is known as "the production board." The production board is essentially a physical chart that lists all of the different elements that need to be fabricated for a particular project. Workers use it to track their progress and report any issues that arise. It's essential for keeping things moving forward on the shop floor and ensuring that everything is on track.

    • Bring all of the reports to detail:
    After the reports are completed, they should be brought to a meeting to discuss the project's progress. During this meeting, any issues that have been identified should be addressed, and solutions should be proposed.

    This is an essential step in the process because it allows everyone to be on the same page and ensures everyone is aware of the project's status. It also allows for any necessary changes to keep the project on track.
    The reporting process is divided into three steps
    Ensuring Quality and Safety

    Quality and safety are of the utmost importance in steelwork fabrication. There are several ways to ensure the quality of your work. This includes having a quality control plan in place and conducting regular inspections. The quality control plan should be focused on:

    Incoming materials: All materials that are used in the fabrication process should be inspected before they are used. This includes checking for damage and ensuring that they meet the required specifications.
