Roll forming is a highly efficient and precise manufacturing process used to produce long, uniform metal profiles. While you may not notice them at first glance, roll formed components are everywhere—in infrastructure, transportation, energy systems, and storage solutions. Let’s explore seven common applications of roll formed products that are integral to our daily lives.
7 METAL ROLL FORMING PRODUCTS IN DISGUISE
Roll forming is behind many of the metal components that support modern infrastructure and industrial functionality. Here are seven examples where roll forming plays a hidden but critical role:
Power Distribution Companies
For data centers, commercial retail, and higher-ed buildings, the power distribution system is vital infrastructure. These systems often include both current-carrying and non-current-carrying components such as copper busbars and cable trays.
Consequently, custom roll formed parts are critical in both current-carrying and non-current-carrying equipment. Roll forming allows for the use of specialized materials like tin-plated copper while ensuring complex profiles and high tolerance control over long production runs.
Warehouse and Data Storage
Warehouses rely heavily on roll formed steel for their structural integrity and storage capabilities. They’re filled (to the max) with old-school roll formed shapes like angles and channels. These components form the backbone of shelving systems, pallet racks, crossmembers, and automated storage rails.
Sheet metal roll forming is great for these industries because it produces parts at high volumes, allows for in-line hole punching, and offers tight tolerance control.
Commercial Food Storage
In commercial food storage environments—such as large refrigerators or walk-in freezers—roll formed parts provide both structural support and hygiene-focused design elements. It creates the components that go into refrigerators and freezers including: textured paneling for aesthetics, kick plates to reduce debris buildup, stainless steel handrails for safety, and insulated shelving frames.
Roll forming offers complex profiles, tricky hole patterns, and tight tolerances for final assembly.
Solar
The solar industry has embraced roll forming as a cost-effective method to produce mounting structures that hold photovoltaic panels in place. Manufacturers use roll formed parts to hold vast arrays of solar panels at specific angles for years into the future.
These include hat channels, C-channels, Z-purlins for ground-mounted solar farms, as well as lightweight ballast trays for rooftop installations. Roll forming allows for proprietary designs, large volumes, and the use of specialized materials.
Trains
Train manufacturing involves some of the longest continuous metal profiles in any industry. Train cars consist of some of the longest, most uniformly shaped components known to man, reaching up to 80 feet long. From exterior roof panels to interior stiffening channels and decorative trim pieces made from stainless steel—roll forming delivers unmatched consistency.
While train manufacturing is a niche market, from exterior to interior, roll forming is the only way to produce these parts:
Trailers & Trucks
Whether it’s delivery vans or 18-wheelers on highways across continents—roll formed steel shapes provide structural integrity and finish-critical elements. Every type of roll formed channel can be used to build the interior framing/skeleton for the cabs on these things. Fenders on semi-trucks also require specific types of wide-profile rolling machines.
Hat and box channels make sturdy, lightweight frames, ideal for transportation applications where strength-to-weight ratio is crucial.
Guard Rails & Sign Posts
Guard rails along highways are among the most recognizable yet overlooked examples of roll formed products. Much like wheel fenders, roll form companies with dedicated machines produce guard rails at incredible speeds, making them affordable and ubiquitous.
Signposts use a similar process—often hot roll forming—which involves heating steel up to 2300°F before shaping it through dies. While they can be cold-formed, these posts are most commonly made via “hot” roll forming.
What Makes These Roll Forming Products Work?
Roll forming works so well across these diverse applications due to its ability to produce complex shapes with high precision over long lengths—all in one continuous process. Hole punching, bending, and cutting to length are all easy to fit into one continuous process, rather than separate steps.
This efficiency reduces labor costs while increasing output volume without compromising quality or dimensional accuracy. Whether it’s multi-bend profiles or finish-critical surfaces—roll forming delivers consistent results every time.
