Making Intermodal and Specialty Freight Containers with Food Grade Welding

To support global demand for food products from pantry staples to specialty and exotic goods, the food grade transport and storage industry is a highly evolved system. Advanced storage systems for transportation, short-term holding, and long-term climate-controlled storage are utilized for all kinds of food products and other perishables, such as pharmaceuticals. Containers for the food industry play a huge role in the transportation and storage of goods, and because of this, highly specialized containers have been developed over the years. Shipping and storing containers made from steel, aluminum, and other metals are frequently manufactured using stud welding operations. If you are fabricating intermodal freight units and other containers for the food industry, you can find everything you need for food grade stud welding processes at Northland Fastening Systems (NFS). We provide stud welding tools for rent or purchase, welding studs in a comprehensive range of dimensions, customizable options for studs, and stud welding accessories as well as the expertise of our own welding technicians.


There have been many designs for food grade shipping and storage containers over the years, but intermodal freight containers helped to standardize sizing and structure to enable better bulk transit and storing. Intermodal freight containers as large as 40 feet long are a commonly used storage option for many goods, including packaged food products. Using food grade stud welding to build these units helps manufacturers meet food safety standards, including Food and Drug Administration (FDA) and U.S. Department of Agriculture (USDA) regulations.


In addition to standardized intermodal units, there have been many specialty containers fabricated using food grade stud welding as a key to food safety. Containers for food grade liquids such as oils, dairy products, and others are repeatedly exposed directly to the food goods. Because of this exposure, it’s critical that these containers can be completely sanitized regularly and protected from corrosion. Any compromise of the container will damage food products and pose health issues.


Food grade stud welding is a solution for many manufacturers producing food storage and transport containers. Not only does food grade stud welding create a smooth, mark-free surface without craggy areas that can collect bacteria, it is also an operation that can use antibacterial metals like stainless steel. Containers made with stud welding are easily sanitized between uses, and the metals used will hold up to strong chemical disinfectants. Weld points and materials used will also withstand exposure to acidic or alkaline food products without harming the composition, flavor, or integrity of the goods.

Specifics of Sanitary Food Grade Welding

Welding of all kinds plays a large role in commercial-grade food equipment. From the shelving units used to store fresh, frozen, and dry foods to stoves and ovens used daily, welding operations are used in the manufacturing process. Stud welding, in particular, is a commonly used manufacturing technique for many types of equipment used in restaurants, hospitals, hotels, and other commercial kitchens as well as in food production and packaging industries. Even some equipment in home kitchens is made with certain components of stud welding. Northland Fastening Systems provides everything you might need for all applications of food grade welding, from studs of all dimensions to tools for rent and purchase in addition to the expert services of our own technicians.


Equipment used in the food industry must meet U.S. Department of Agriculture (USDA) and Food and Drug Administration (FDA) standards for sanitation, including the very specific requirements of the FDA’s Food Safety Modernization Act (FSMA). This means, every step of the fabrication process must guarantee that end results meet those standards. When it comes to stud welding, regulations are in place for food grade welding processes.


The foundational requirements of food grade welding include:


  1. Precise Finish: A smooth finish with the elimination of burrs and sharp particles of metal of all kinds must be accomplished. Even microscopic burrs or sharps can compromise a food grade piece of equipment. Rough surfaces should also be smoothed and finished in a way that removes any spaces for food particles to get caught and build bacteria colonies.
  2. Sealed and Bolted: The full framework of a piece of equipment should be sealed at connection points. Simply bolted connection points can have opportunities for increased vulnerability to corrosion or storage of bacteria. Components that can be detached for cleaning must also be built in a way that reattaches with a full seal.
  3. Correct Design: The equipment should be designed in a way that only uses internal angles or corners. External angles create spaces in which bacteria can thrive, which compromises any food grade equipment.
  4. Surface Working: Surfaces should be worked in a way that doesn’t overstress the materials. Overworking can leave any layers protecting against oxidation susceptible to being quickly stripped away.
  5. Compatible Weld: The stud and the surface material must be compatible. Any incompatible welds are more vulnerable to corroding and contamination food or cracking under thermal stress.


If you are fabricating food grade equipment of any kind, it’s critical to consider these requirements and any other standards outlined in the FSMA before beginning your project.
