Square Bar Defined

Square bar is known for its high level of structural durability and is utilized in a number of applications for various industries.

• Furniture Manufacturing: Due to its significant strength and small size, square bars are used in a wide array of furniture and add support to tables, chairs, benches, and stools.

• Food Processing: Cold-finished square bars are frequently used in stainless steel vats to add internal structural integrity. The square bars also act as legs that allow the vat to remain upright.

PROPERTIES OF ALUMINUM

The high strength to weight ratio of aluminum, coupled with its corrosion resistance make it a great material for truck and 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.

Hot 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.
