PROPERTIES OF ALUMINUM
The high strength to weight ratio of aluminum, coupled with its corrosion resistance make it a great material for truck trailer manufacturers or marine applications. In addition, aluminum has ideal electrical and thermal conductivities, and is heat resistant, making it an ideal choice for power transmission equipment manufacturers.
Aluminum can be easily formed and machined, and accepts a wide variety of surface finishes, although in most applications it needs no protective coating.

Learn MoreHot Rolled
HOT ROLLED STEEL VS. COLD-FINISHED STEEL
There are many differences between hot rolled and cold-finished steel. The first is the process. Hot rolled steel goes through one high heat treatment process, while cold-finished steel requires further processing. After cooling to room temperature, cold-finished steel is then rolled again. This additional treatment process results in a stronger metal that can be used for more precise applications or projects that require a smoother aesthetic appearance. Compared to cold-finished steel, hot rolled steel surfaces are rougher. Hot rolled steel is typically used in applications where precise shapes and tolerances are not critical.

304 vs. 316 STAINLESS STEEL
The most common stainless steel alloys are 304 and 316/316L. 304 stainless steel is easy to form, weld, stamp, machine, and fabricate. It holds a high resistance to temperature and corrosion. This material also scores high on the strength index. Stainless steel is very easy to clean and is ideal for industries that demand high sanitation and frequent washing. 316 holds the same resistance, toughness, and strength properties as 304. The difference between 304 and 316 stainless steel is their elements. 304 is 18% chromium and 8% nickel. 316 is 16% chromium, 10% nickel, and 2% molybdenum. 316 also offers more protection against pitting.
