As a leading steel supplier and service center in New England, Central Steel Supply Company maintains an expansive inventory to accommodate our customers’ project requirements.

We Have Your Steel Needs Covered

With over 8 million pounds of steel in stock, 600+ products ready, and sourced material options, we provide the steel you need to keep projects moving.

Finishes: Galvanized, Painted, HRPO

To fulfill the specific requirements of your application, our team also offers a range of finishing treatments to enhance aesthetics or material properties like durability in your steel products. We provide finishes such as:

  • Galvanized: Galvanized steel from stock or custom galvanizing upon request for all our material—providing durable, corrosion-resistant materials you can rely on for any project.
  • Painted: We offer primarily primed steel from stock, with the option to apply custom colors and finishes upon request—enhancing durability while giving your project the look you want.
  • HRPO (Hot-Rolled Pickled and Oiled): This process removes scale and oxidation from hot-rolled steel and applies a light oil coating to prevent rust, resulting in a cleaner surface ideal for further processing or fabrication. Offered in sheets, tubes, and plates—available from stock or sourced to meet your specific project needs.
  • Abrasion-resistant (AR): Designed to withstand heavy wear and extend the life of your projects, our AR plates and flat bars are available from stock or can be sourced to meet your specific needs.

Finishes

We offer a variety of steel finishes to meet durability, appearance, and other application needs. Many are available from stock, and others can be sourced or customized to your project’s requirements.

Galvanized

Coated with a protective layer of zinc to prevent rust and corrosion, galvanized steel offers long-lasting durability against the elements.
We stock galvanized material or can provide custom galvanizing for any of our products—ensuring a corrosion-resistant finish built to last.

Stock Galvanized Material:

Painted / Primed

Our primed and painted materials are coated to protect against corrosion and to provide an excellent surface for additional paint or finish layers.We stock primed material or can source custom blasting and priming for any of our products—ensuring a corrosion-resistant finish built to last.
