Steel Fabrication Shop
Our Steel Fabrication Shop Capabilities
As custom metal fabricators, we combine innovative technology with expert processes and finishing services to offer you a complete solution. Our facility in Mount Vernon, Indiana, can fabricate steel parts in-house to help maximize your budget, including assembly of platforms with grating and handrail, stair stringers, or trusses.
We will work with you, your budget, and your unique needs to manage logistics—we’ll ship steel all over North America and overseas. We even run our own hot-shot truck and trailer for loads less than 18,000 lbs to simplify regional shipping.

Steel Fabrication Technology
We utilize state-of-the-art technology for our structural steel fabrication process. As a result, TMI Fabricators is able to create custom industrial steel products that meet the specific needs of our clients.
- SDS/2 Modeling Software: Detailing services using the latest SDS/2 modeling software to assist in fabrication.
- Strumis Purchasing Software: Strumis, a cutting-edge purchasing software system that streamlines the working process, maximizes material efficiency, and increases productivity.
- CNC Cutting and Drilling: CNC technology with a ficep excaliber single spindle drill line and a Messer Edgemax burntable for precision cutting and drilling.
Quality Assurance Process
TMI Fabricators is committed to providing the highest quality steel fabrication products and services. We have a comprehensive quality assurance process that begins with the careful selection of materials. We only produce high-quality steel that meets or exceeds industry standards.
Once the materials have been selected, our team of experienced fabricators will use state-of-the-art equipment to cut, bend, and weld the steel into the desired shape. During the fabrication process, our quality control team will conduct regular inspections to ensure that the steel meets our strict standards. Once the fabrication is complete, we will install the steel according to the specifications provided by the customer.
- American Welding Society certified: All welders are AWS-certified.
- AISC code adherence: Standard tolerances of a 1/8” while adhering to the AISC code of standard practice.
- 100% inspection: One hundred percent inspection with multiple hold points throughout by certified welding inspectors.
- Mill certifications: Mill certifications for every piece of material.
- Inspection record-keeping: Meticulous record-keeping of inspections—from dimension checks to hole layouts and paint DFTS.
We have a broad steel finishing capacity range, from applying a simple red oxide primer to a variety of three-part systems.
At TMI Fabricators, we take pride in our steel painting process. Our in-house painting area is 100′ x 150′, and we have a NACE level 2 inspector who oversees all painting to ensure the highest quality. We use a three-step process for painting steel: first, we pre-treat the steel to ensure optimal paint adhesion; next, we apply the primer and paint; finally, we cure the paint to ensure a long-lasting finish. This process produces a high-quality paint job that protects your steel from corrosion and wear.
Our blasting process includes a 20’ x 50’ steel shot/grit blasting booth. We offer mechanical and hand blaster options, so you can choose the best method that suits your needs. Our mechanical blasters use high-pressure air to remove rust, paint, and other debris from metal surfaces, while our hand blasters are perfect for smaller jobs or areas that require more precision.
Types of Steel We Fabricate
We fabricate a wide range of steel types, including aluminum, carbon steel, stainless steel, hardened steel, and more.
Carbon steel fabrication involves taking a steel alloy and adding carbon to it in order to increase the hardness and strength of the metal. The steel is then heated to a high temperature and cooled quickly, which helps to preserve the new properties of the metal. Carbon steel is often used in construction and manufacturing applications.
Our stainless steel fabrication process begins with creating a “primary alloy.” This is typically done by melting together iron and chromium in a furnace. Next, we add other elements, such as nickel or molybdenum, to create the desired alloy.
Once the primary alloy has been created, it can be made into stainless steel in one of two ways: through hot rolling or cold rolling. Hot rolling is a process that involves heating the primary alloy to over 1700 degrees Fahrenheit before shaping it into products. Cold rolling, on the other hand, is a process that involves shaping the primary alloy at room temperature.
To make hardened steel, TMI Fabricators first creates steel with high carbon content. This is typically done by adding extra carbon to molten iron. Once the steel has cooled and solidified, it is then heat treated to further increase its hardness. The steel is heated to a high temperature and then cooled very quickly. This process, known as quenching, creates a harder steel that is less likely to break or deform under stress.
Abrasion plate is steel that has been specifically designed to resist wear and tear. It’s often used in high-impact areas where there is a lot of friction, such as chutes, conveyors, and decks.
Aluminum is one of the most versatile materials available for fabrication. It is strong yet lightweight, making it ideal for a wide range of applications. Aluminum can be easily formed into shapes, and it has a high resistance to corrosion. Making aluminum involves drawing the metal out into thin sheets, which are then rolled and welded together. The resulting product is then anodized to give it a protective coating.
Steel Forming Processes
Our forming processes include sawing, shearing, rolling, oxy-fuel cutting, and plasma cutting. This allows us to create a variety of shapes and sizes to meet your needs. We use state-of-the-art equipment to ensure precision every time.
The saw blade is mounted on a motorized arm and is passed through the steel at high speed. It can be operated manually or by an automatic control system.
Steel sheering is a process that is used to cut steel into thin sheets. A hydraulic press applies pressure to the steel, which causes it to fracture along its grain. The result is a clean, straight cut that can be used for a variety of applications.
Steel rolling involves a three-step process that passes the steel through a series of rollers, each of which applies pressure to the steel and shapes it into a specific configuration. The first step in steel rolling is known as threading, during which the steel is passed through a series of rollers that creates threads in the steel.
This process is followed by drawing, during which the steel is passed through rollers that decrease its diameter. Finally, the metal undergoes finishing, during which it is passed through rollers that smooth its surface.
The oxy-fuel cutting process uses a torch to heat steel until it reaches its melting point. The biggest advantage of oxy-fuel cutting is that it can be used on any type of steel, regardless of thickness. Additionally, oxy-fuel cutting produces little waste, as the molten steel can be collected and reused.
The plasma torch uses an electrical arc to ionize a stream of gas, creating a plasma jet that can reach temperatures of up to 30,000 degrees Fahrenheit. This high-heat plasma jet is then used to cut through the steel. Plasma cutting is a very efficient way to cut steel, and it can produce clean, precise cuts with very little distortion.
