When it comes to designing a product, transitioning from an initial concept to a fully realized custom metal fabrication isn’t always simple. This is where 3D modeling services can make a huge difference by helping you move smoothly from CAD drawings through prototyping and into a clear 2D plan for manufacturing.
This is why it’s crucial to work with a structural steel detailer who has real-world experience in fabrication. They should be skilled in using CAD, 3D modeling, and CAM software to determine the most efficient way to process your design. This is especially important in structural steel detailing, which involves several steps before a product can move on to other stages of development.
Let’s start by looking at the design phase and how it plays a central role in the entire structural steel detailing process.
Design Analysis Drives Custom Metal Fabrication
As we mentioned earlier, metal fabrication design is more than just turning an idea into a drawing. It's about transforming that concept into a tangible 2D or 3D representation. Think of your design as your first draft — it's the starting point for your custom metal fabrication journey.
Once you have your initial design, a steel detailer can take that draft and begin using 3D modeling to create shop drawings for the fabricator. This is where adjustments can be made to optimize the part for production. Keep in mind that just because a design looks good on paper doesn't mean it will be easy to manufacture. This is especially true for custom fabricated steel parts, which often go through a dedicated "fabrication design" stage before moving forward.
This is why working with an experienced partner like Southern Metal Fabricators is so important. We act as both your engineering and design consultant, analyzing key factors to ensure your final product:
- Can be successfully manufactured.
- Retains strength, durability, and structural integrity.
- Can be assembled or arranged as intended.
Metal Forming Shapes Your Final Product
Your structural steel detailer must be able to bend, shape, punch, and form metal to meet the demands of custom fabrication. Metal forming involves using industrial machines to shape raw materials into precise forms, applying the right amount of force and pressure to achieve tight tolerances.
For example, sheet metal rolling is a common technique used in custom metal fabrication. Hot rolling is often used for creating raw stock, while cold rolling is preferred for shaping sheets or plates into curves or cylinders. Plate rolling creates curved sections, and angle rolling produces sharp, 90-degree bends.
Metal bending is another essential step. Our press brakes, including a 400-ton machine capable of handling ¾-inch steel plates, allow us to bend metal up to 12 feet long at any angle. For heavy-duty punching, our 50-ton hydraulic punches provide strong, consistent results, while our CNC 30-ton Strippit press ensures precision when needed.
Cutting Is Key to Meeting Structural Steel Standards
Custom metal cutting is vital for meeting your specifications in structural steel detailing. Cutting processes may include specialized saws, shears, and high-precision tools like plasma and laser cutters. Punching is also a key part of this process, allowing for the creation of holes and openings in metal pieces.
At Southern Metal Fabricators, we can cut metal into almost any size or shape — from thin copper sheets to thick carbon-steel I-beams. With advanced equipment like our Trumpf laser cutter, we’re equipped to handle nearly any requirement, no matter the scale.
Our cutting capabilities include metal sawing, CNC plasma cutting, steel plate shearing, and laser cutting, ensuring we meet even the most demanding specifications.
Finishing Ensures Quality in Custom Metal Fabrication
A full-service metal finishing shop is essential for delivering high-quality custom metal fabrications. At Southern Metal Fabricators, we offer a range of on-site finishing services, including surface preparation and final touches. We understand that carbon steel can rust quickly if not properly protected, so we prioritize immediate painting to prevent corrosion.
Our finishing services include:
- Metal Surface Preparation: We prepare surfaces for SP1–SP10 grades, using techniques like sandblasting to save time and labor while achieving a superior finish.
- Hot-Dip Galvanizing: Often applied after assembly, we can also use galvanized material from the start, especially for outdoor structures like ladders and stairs.
- Painting: After surface prep, we apply primer and paint in a controlled environment to ensure a quality finish. We can measure and document coat thickness for projects requiring strict tolerances.
Custom Welding Services Ensure Strong Assemblies
In addition to structural steel detailing, we offer custom welding services to ensure every fabricated part and subassembly fits perfectly. Our team of certified welders has over 30 years of combined experience, adhering to all relevant codes and standards such as ASME, AWS, and CWB.
We use a variety of welding methods, including MIG, TIG, and stud welding, and are qualified to weld structural steel according to AWS D1.1 (carbon steel above 1/8â€) and AWS D1.6 (stainless steel above 1/16â€).
Choosing the Right Steel Detailer for Your Project
As we've discussed, it's essential to work with a structural steel detailer who understands your unique needs. A great detailer should possess certain qualities, especially during the critical design and fabrication phases.
Look for someone with:
- Strong communication skills: They need to collaborate with designers and fabricators to avoid issues and streamline the process.
- Familiarity with industry standards: Whether it's OSHA, AISC, or load limits, a good detailer knows what matters for safety and compliance.
- Expertise in 3D modeling and design software: They should be comfortable with CAD, 3D modeling, and CAM tools to help optimize your design for manufacturing.
