Since 1963, Delta Steel, Inc. has been a leader in the global structural steel market. Because of our capable machines, skilled experts, and utmost dedication to our customers, we are now one of the largest carbon steel plate suppliers in the southwest United States. Our specialization includes producing high-quality carbon steel plates in various sizes, widths, and lengths, depending on customer specifications.
A carbon steel plate is one of the most commonly used materials for structural and building applications. It consists of carbon and iron, flattened into thin pieces using different forms of industrial processes. Carbon steel sheets and plates have the same composition but vary in thickness.
A steel plate is made from various metals, including aluminum, brass, and copper. Carbon, in particular, is an excellent choice for structural, architectural, and industrial use due to its strength, flexibility, malleability, and durability.
Making steel plates is one of the oldest, most basic, and most versatile metalwork forms. It begins by heating metal slabs and running them through rolling stands. This step elongates and thins the metal until it reaches the specified thickness. Finally, the steel plate is cooled and turned into the desired shape.
Commercial Quality Steel Plate Suppliers
As the leading carbon steel plate supplier, Delta Steel carries Commercial Steel (CS/CQ) plates in various options and grades, including hot rolled, cold rolled, hot rolled-pickled & oiled, and galvanized. They range in thickness from 3/16 inches to 8 inches thick, and several patterns sizes up to 120 inches x 480 inches. Our commercial-quality steel plates promise quality, safety, and durability that suit the needs of our manufacturing customers.
Delta Steel produces durable carbon steel plates of various hardness and carbon content through multiple processes. Commercial steel (CS/CQ) is often used in the automotive and furniture-making industries. This grade is well-suited for flat applications that require little to no bending.
The hardness of steel is measured through the Rockwell scale. Generally, carbon steel falls from B to C, depending on the steel plate’s carbon content.
Delta Steel’s commercial quality steel plates are produced from low-carbon steel and are well-suited for diverse applications. From simple bending, moderate drawing, and welding, our low-carbon steel plates are a cost-friendly option with a simple finish and mild ductility. In addition, it is easy to weld, form, and drill, making it the perfect choice for the following applications:
- Automotive panels
- Drip pans
- Fuel tanks
- Railroad Tracks
Hot Rolled Pickled & Oiled
Use our hot-rolled pickled and oiled plates for a smooth, clean surface. Our commercial quality steel plates are highly recommended for stamping or typical drawing applications, perfect for undesirable tight oxide scales. Enjoy easy-to-paint clean plates, ready to use for the following applications:
- Rack Systems
- Lawn and Garden
- Welding finishes
- Light poles
- Gas cylinders
Produced from low-carbon steel, our cold-rolled commercial quality steel plates are best used for exposed or unexposed parts involving bending, moderate drawing or forming, and welding. Our high production, selection, and steel processing standards produce high-quality, high-performance steel plates. In addition, cold-rolled ASTM (American Society for Testing and Materials) steel plates are commonly used when dimensional tolerances, strength, and surface finish quality are critical, such as:
- Metal furniture
- Automobile components
- Electronics hardware
- Home appliances and components
- Lighting Fixtures
Having coated in zinc for rust protection and corrosion resistance, our galvanized steel plates are recommended for construction, metal fittings, kitchen and home appliances, and automotive parts. With our galvanized ASTM steel plates, you’ll never worry about water, moisture, and rust again. We guarantee a longer lifespan and reduced maintenance costs for the following applications:
- Exterior building products
- HVAC products
- Garage doors
- Safety Fencing
- Automotive parts
- Commercial and residential steel framing
