Metal Fabrication Materials


Here at B&H we use the highest quality sheet materials available, nearly every alloy and grade available, and ensure that all of our engineers and metal workers have an up-to-date training on how to properly punch, cut, bend, and create all forms of metal.

Stainless Steel

Stainless Steel is a very common metal processed at Dalsin Industries to manufacture various OEM products for wide-ranging applications such as on-highway vehicle doors/body panels, medical equipment, medical carts, NSF food energy dispensing stations, digital display, and variable messaging controls, consumer products, kiosks, and various enclosures. Stainless Steel sheet metal is a manufacturing-friendly material that has several advantageous features: durability, formability, weldability, machinability, weatherability, corrosion-resistance, and high recyclability.


Aluminum is a popular metal at B&H for making OEM goods for a variety of applications, including highway automobile doors/body panels, medical equipment, medical carts, energy dispensing stations, digital display screens, and variable messaging controls.
Aluminum sheet metal is manufactured in a variety of shapes and sizes. It has several advantages, including lower weight per surface area, durability, formability, weldability, machinability, weatherability, and corrosion resistance, while using recyclable aluminum sheet metal that is conductive, reflective, and long-lasting.

Cold Rolled Steel

Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products.

Hot Rolled Steel

Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the recrystallization temperature it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools off it will shrink slightly.


Brass is a very malleable alloy of copper and zinc that is non-magnetic and corrosive resistant. It is an easily machined metal with very good joining, plating, polishing, and finishing characteristics. Aldine commonly fabricates brackets and smaller components using brass sheet.


Titanium is created from beach sands rutile, which is gathered in South Africa and Australia. Manufacturers combine rutile with chlorine gas and either coke or tar. Through heat, the ingredients become a sponge that is melted until it is an ingot. They also use Vacuum Arc Remelting (VAR) and cold hearth furnaces to melt the titanium. The ingot is then sent through mill forms to create metal. When manufacturers expose titanium to oxygen, it develops an oxide film layer. This is key to creating products that are resistant to corrosion and erosion. If titanium is scratched, it can heal itself as soon as it is exposed to oxygen and grows a new oxide film.
