Structural Steel Pipe in Philadelphia, PA

McKnight Steel & Tube Co. is a trusted steel pipe supplier in Philadelphia, PA. We stock carbon steel and galvanized structural steel pipe for construction in various diameters, thicknesses, and lengths to suit a wide range of applications.

Types of Structural Steel Pipe

Structural steel pipe is available in numerous shapes and finishes for various construction applications, including framing, columns, and support. There are also different materials used for structural steel pipes to meet different needs for strength, versatility, and corrosion resistance. We distribute the following types of structural steel pipes ready to ship from Philadelphia:

• Carbon Steel – A steel alloy made with carbon and iron, carbon steel is built to meet mechanical strength standards for heavy machinery and construction projects. It is both lightweight and durable and available in several ASTM grades.
• Stainless Steel – With high corrosion resistance and strength, stainless steel is utilized in marine environments and other corrosive environments like industrial zones or rural agricultural areas.
• Alloy Steel – We carry a wide variety of alloys, including aluminum, carbon, and nickel, to meet different performance standards and function in demanding applications like high-temperature or high-pressure environments.
• Galvanized Steel – Coated with a protective layer of zinc, galvanized steel pipes are preferred when durability, strength, and corrosion resistance are most essential.

Structural Steel Pipe Specifications

In addition to shape and material, structural steel pipes are categorized by thickness and ASTM specifications. Pipe wall thickness is referred to as Schedule by the American National Standards Institute. These classifications are Schedule 10, Schedule 40, Schedule 80, and Schedule 160. Schedule 40 is standard in construction, while Schedule 80 may be used in applications demanding a higher strength material.

ASTM specifications define standards for different types of structural steel pipe for construction. For example, A500 is used for cold-formed and seamless structural tubing used for bridges and buildings.

FAQs for Steel Pipe Suppliers

What industries commonly use structural steel pipes?

Structural steel pipes are used across many industries, including commercial construction, industrial applications, agriculture, and transportation.

Are your structural steel pipes ASTM-compliant?

Yes, we stock and ship steel pipes that meet ASTM standards and specifications.

How quickly can I get a quote for structural steel pipe?

We are available Monday through Friday from 8:00 a.m. to 5:00 p.m., and our team can typically provide a quote within one business day.

What is the difference between structural steel pipe and mechanical tubing?

Structural steel pipe is designed for high strength to support load-bearing applications in building construction and infrastructure. Mechanical tubing emphasizes precise dimensions and specific surface coatings to support use in machinery like automotive, medical, or manufacturing equipment.

Do you offer custom lengths or cut-to-size structural pipes?

Yes, we cut pipes to size on our production saws, so they can be cut to any custom length your project requires.

What are the benefits of using welded structural steel pipe?

Welded structural steel pipe has a continuous seam for high tensile strength, making it a good fit for construction applications. Structural pipe manufacturers are also able to produce welded pipes faster and more efficiently, so they can help to reduce material costs.
