QUALITY CARBON AND STAINLESS PRODUCTS
From design to distribution, our extensive inventory of flat-rolled aluminum coils can be slit, cut-to-length (CTL), or sheared to meet your manufacturing requirements.
Our steel stock is available in the following formats:
- Cold Rolled
- Hot Rolled Pickled and Oiled
As a full-service aluminum products supplier and service center, American Douglas Metals (ADM) offers quality and reliability to exceed the needs of diverse industrial and manufacturing applications across the globe.
THE FLAT-ROLLING PROCESS
ADM has the highest quality, state-of-the-art production equipment that allows us to control the processing detail of each project with ease. Generally speaking, flat-rolled products are usually made by rolling steel between rolls to reduce the thickness and lengthen it. Our steel strip, coil, foil, rod, pipe, plate, sheet, and other profiles are produced in a facility created to service different rolling techniques and finishes for your project needs.

THE FLAT-ROLLED STEEL TECHNIQUES
Hot rolling means that the sheet of steel is processed into a coil at a temperature of 1700 Fahrenheit. This allows it to become more malleable and easier to roll into a coil for storage, transportation, and later processing by the client company. Hot rolled steel has a higher surface quality which allows it to be best used for mechanical properties such as automotive building and creating industry-specific equipment.
Cold-rolling products are processed similarly but include an added step to achieve a more exact dimension on the steel finish. After the steel has cooled down, it is run through the rolling mill once again to modify the surface area. Cold rolling creates a product that works best for projects that require smooth services, well-defined edges, and corners such as domestic appliances. The only downside to the production of this material is that it requires more pressure compared to hot rolling because the cooled steel is not as malleable.

This steel finish involves adding a coating of zinc to the steel to offer an added protection and prevent rusting. Galvanized steel is one of the more popular finished products due to its extended durability. The zinc protects the base metal by acting as a barrier creating a long-lasting and high-quality steel product.
Galvannealed finish is created through the combination of the annealing process and hot-dip galvanizing to create its final coasting. The steel is coated in the hot-dip zinc and then headed to induce alloying between the zinc coating and the steel. The finish replicated a dull matte surface that allows for paint adhesion and welding as needed.
Galvalume consists of a special coating comprised of zinc, aluminum, and silicon to protect the steel from oxidation. It has an advantage over other galvanized materials due to its enhanced protection from rust when exposed to water and other liquids. This hot-rolled steel works well for outdoor environments such as it can hold its own against snow, ice, and rain.
Acrylume offers more protection to galvalume steel products. Acrylume is a clear, organic resin that is roll coated onto the metal surface and creates a layer of acrylic to create corrosion resistance.
Painted finishes offer extreme durability in outdoor exposure as well as indoors because of our high-quality paint system. Pre-painted metal sheet finishes are uniquely designed in that they provide a hard, abrasive resistant coating, yet allow the flexibility for extensive forming and fabricating on a metal surface.
Embossing is a marking process that leaves raised designs on metal and other materials. The process utilizing rollers or dies combined with pressure to mark the metal sheets with a series of designs. This technique is great for creating slip-resistant platforms, stairs, and a range of other custom-designed steel and metal products.
Pickled and Oiled
Steel pickling and oiling is a type of metal surface treatment finish to remove surface impurities like rust and carbon scale from a hot-rolled steel product. The steel is dipped into a bath of pickle liquor which consists of hydrogen chloride acid solution. The oiling process is similar but the solution the material is dipped into consists of a water-soluble or a mineral-based oil to help prevent flash rust while the material waits for further fabrication.
