Coastal Metals – Large Diameter Round Bars & Steel Supplier in San Bernardino
Looking for a reliable metal supplier in San Bernardino? Coastal Metals is your go-to source for high-quality metals and expert services. With one of the most extensive inventories in the industry, we provide everything you need for your project, from carbon steel to stainless steel and aluminum. Our wide selection of materials and comprehensive services, like product cutting, turning, and grinding, ensures that we can meet the needs of your next big project.
Materials We Offer in San Bernardino:
Carbon Steel
Carbon steel is the backbone of many industries. We stock three types of carbon steel, depending on your project’s requirements:
- Low-Carbon Steel (Mild Steel): This steel has less than 0.25% carbon and is easily weldable, making it great for general fabrication.
- Medium-Carbon Steel: With 0.25-0.6% carbon, this steel can be heat-treated for enhanced strength and hardness. It’s often used in machinery parts.
- High-Carbon Steel (Carbon Tool Steel): Tough and durable, high-carbon steel contains 0.6-1.25% carbon and is ideal for tools and cutting edges.
Alloy Steel
Alloy steel is enhanced with elements like nickel, chromium, and molybdenum, making it stronger and more resistant to wear. Coastal Metals stocks:
- Low-Alloy Steel: Ideal for general construction and structural use.
- High-Alloy Steel: Containing over 10% chromium, this steel is perfect for applications needing corrosion and heat resistance, such as in the aerospace and automotive industries.
Aluminum
Aluminum is lightweight, corrosion-resistant, and versatile. We stock 6061-T6 Aluminum Bars with diameters up to 20 inches. It’s perfect for projects requiring strength without excessive weight, like aerospace and transportation components.
Tool Steel
Tool steel is the preferred material for making tools, molds, and dies. It stands up to high temperatures, pressure, and abrasion, ensuring longevity in demanding conditions. Our tool steel offerings are perfect for making cutting tools, hand tools, and molds used in various industries.
TG&P Metals
Turned, Ground, and Polished (TG&P) metals are ideal for high-speed applications that require precise dimensions. Our 4140 TG&P metals offer superior strength and fatigue resistance, making them the ideal solution for shafts, bearings, and more. We carry 4140 TG&P bars up to 6 inches in diameter.
Bronze
Bronze is a tough, corrosion-resistant metal, primarily used in marine, automotive, and electrical industries. Bronze’s low friction makes it perfect for machine bearings and other parts that experience constant movement and wear.
Stainless Steel
Stainless steel is known for its corrosion resistance and strength. At Coastal Metals, we stock various grades of stainless steel, including:
- Austenitic Stainless Steel: Most commonly used, known for strength and malleability.
- Ferritic Stainless Steel: Magnetic and highly resistant to corrosion.
- Duplex Stainless Steel: Stronger than austenitic and ferritic combined, used in marine applications.
- Martensitic Stainless Steel: Great for medical tools due to its high hardness.
Forging Materials
We offer metals specifically for forging, including carbon steel, alloy steel, stainless steel, aluminum, and brass. These materials can be forged using either rolled ring forging or press forging, providing superior strength for heavy-duty applications.
Services Provided in San Bernardino:
