Hot Rolled Black Pipe
Hot Rolled Black Pipe is a tubular product convenient form for use as structural members such as columns, bollards, sign poles, structural supports, and piling.
- A53 Grade B
- Low-carbon steel
- Hot-rolled, mill finish
- Excellent weldability
Overview
Hot Rolled Black Pipe is a fundamental, cost-effective structural steel tubular product widely used throughout the Los Angeles construction and industrial sectors. Manufactured to meet rigorous ASTM standards, this pipe is known for its strength, durability, and versatility. Unlike mechanical tubing sized by exact outside diameter (OD), structural steel pipe is categorized by its nominal inside diameter (ID), making it an economical choice for a vast range of applications.
It serves as an essential component for Metal Supply Los Angeles projects, from robust structural supports and columns to fencing, bollards, and sign poles. The hot-rolling process gives the pipe its characteristic dark, scaly oxide finish (mill scale), which provides a degree of protection during storage and handling. Common grades include ASTM A53 and ASTM A500, with A500 offering slightly higher mechanical properties ideal for demanding structural frameworks. For projects requiring enhanced corrosion resistance, this black pipe can be further processed into galvanized pipe.
Whether you need standard stock for a quick turnaround or custom-cut lengths, our inventory supports the diverse needs of contractors, fabricators, and engineers across Los Angeles. This product is a cornerstone for construction metal, providing reliable performance for structural applications, roll cages, trailer frames, hand railings, and more, making it a top choice for professional B2B clients seeking quality and value.

- Construction & Infrastructure: Bollards, sign poles, piling, hand railings, and rebar supports
- Industrial Fabrication: Roll cages, truck racks, trailers, and machinery frames
- Fencing and Security: Used as primary posts for metal fencing (often as galvanized fence pipe) and in security applications
- General Construction: A versatile material for a wide array of Metal for construction projects in Los Angeles
- Agricultural: Structural supports for barns, equipment frames, and irrigation systems
Weldability
- Welds readily by MIG, TIG, Stick, or Flux-core processes.
- Select filler based on section thickness, joint design, position, and service requirements.
- Remove mill scale in the weld area for best results.
How to Measure
Specify by: Nominal Pipe Size (NPS) and Schedule (e.g., 4 inch pipe, SCH 40). For Ordering: Provide NPS, Schedule, ASTM Grade (A53 or A500), and required length. Note: The actual outside diameter (OD) of a pipe is larger than its nominal size. For example, a 4 inch NPS pipe has an OD of 4.5 inches. Tolerances: Refer to ASTM standards; slight variations in OD and wall thickness are standard. For custom fabrication projects alongside materials like square tubing or corrugated metal, consult with our experts for compatibility guidance.
Order Checklist
