Harbor Pipe & Steel maintains a 400,000 square foot warehouse, allowing us to maintain a large sheet metal supply for our four steel companies. As a large steel service center we can meet the widest range of steel requirements.


Hot Rolled Steel Products:

Hot Rolled Steel – A36, A1011, A1018
A durable and workable material at a reduced cost, making this an ideal material type for a wide range of finished products. We offer three hot rolled steel products, A36 and also A1011 and A1018 in type CSB. A1011 and A1018 are also available in grade 33 and grade 36.

Hot Rolled Coil is available in thicknesses ranging from 16ga to ½” and widths of 36”, 48”, 60” and 72” wide. We can level to standard or custom lengths.

Hot Rolled Pickled and Oiled (P&O) – A36, A1011, A1018
Hot Rolled material is put through a pickling process (acidic solution) before having a thin layer of oil applied. This leaves a cleaner, smoother surface than traditional hot rolled that helps with some downstream work such as laser cutting and painting.

We offer P&O Coil in A36, A1011, A1018. All products are available in thicknesses ranging from 14ga to ½” and widths of 48”, 60” and 72” wide. We can level to standard or custom lengths.

Floor Plate – A786
Also known as Tread Plate or Diamond Plate. This is a hot rolled product that has raised “diamonds” that provide additional traction for walkways and stairways, etc.

Floor Plate Coil is available in thicknesses ranging from 14ga to ½” and widths of 48”, 60” and 72” wide. We can level to standard or custom lengths.

High Strength Steel – A1011 and A1018, A572
Hot Rolled material is produced with higher yield and tensile strengths for structural applications.

Available in Grade 50, Grade 55, and Grade 80. Thicknesses ranging from 14ga to ½” and widths of 48”, 60” and 72” wide. We can level to standard or custom lengths.


Cold Rolled and Coated Steel Products:

ASTM A1008 Cold Rolled Steel delivers tight tolerances, a smooth finish, and excellent formability — making it ideal for stamping, forming, and other processing methods. It’s available in a wide range of gauges and widths, and can be custom leveled to your specifications. Coated options provide added benefits such as corrosion resistance and paint-ready surfaces. Corrugated versions are also offered for construction applications like roofing and siding.

Available in thicknesses from 24ga to 10ga and standard widths of 36”, 48”, 60”, and 72”. Material can be leveled to standard or custom lengths to meet your specifications.

  • A1008 Cold Rolled Steel – Known for its smooth surface and precise tolerances, making it ideal for forming, fabrication, and general processing applications. Available in thicknesses from 24ga to 10ga and in standard widths of 36”, 48”, 60”, and 72”.

  • Galvannealed Steel (A653) – Features a zinc-iron alloy coating that provides excellent corrosion resistance and a smooth, uniform, paint-ready surface. Available in thicknesses from 24ga to 10ga and standard widths of 36”, 48”, 60”, and 72”.

  • Galvanized Steel (A653) – Hot-dip zinc coated on both sides to provide exceptional corrosion resistance, making it ideal for outdoor and high-moisture applications. Available in thicknesses from 28ga to 10ga and standard widths of 36”, 48”, 60”, and 72”.

  • Electro-Galvanized Steel (A879) – Features an electrolytic zinc coating that delivers a smooth, uniform, and paintable surface with excellent corrosion resistance. Available in thicknesses from 24ga to 14ga and standard widths of 36”, 48”, and 60”.

  • Bonderized Steel (A653) – Phosphate-treated and chromate-coated to create a dull, paint-ready finish that requires no additional surface preparation. Available in 24ga and 26ga thicknesses, 48” wide.

  • Corrugated Sheets – Roll-formed for added strength and durability, ideal for roofing, siding, and fencing applications. Available in cold-rolled, galvanized, and galvalume materials, offered in a variety of patterns and lengths to suit your project needs.

  • Mill Flat Plate (A36 & A572) – Hot-rolled plate produced in wider and thicker sizes than coiled hot rolled, ideal for applications where strength is the primary requirement. Our A572 plate is available in Grade 50 for enhanced strength and performance:
    Thicknesses: ¼” to 2”
    Stock Sizes: 96”×240”, 96”×480”, and 120”×480”

  • A606 Weathering Steel (Corten®) – A high-strength weathering steel that naturally develops a rust-like patina over time, reducing the need for painting or maintenance. Ideal for outdoor and structural applications where long-term durability and a distinctive aesthetic are desired:
    Thicknesses: 16ga up to ¼”
    Widths: 48” and 60”
