A500/A513 Carbon Steel Rectangular Tubing 2in x 4in x 72in - Durable

Our review of the A500/A513 Carbon Steel Rectangular Tubing finds it a practical choice for builders and fabricators who need a sturdy, cost-effective structural section. The biggest reason to buy is its balance of strength and weldability: this tubing meets ASTM-A513 and is suited to load-bearing uses while remaining straightforward to cut and join. For anyone making frames, supports, or custom metalwork where predictable performance and value matter, this tubing delivers dependable material without premium pricing.

Key Features

• A500/A513 construction: Provides consistent structural properties and meets ASTM-A513, giving confidence for use in building and industrial projects.
• 2in x 4in profile: The rectangular dimensions are useful for horizontal and vertical framing where flatter surfaces and predictable bending strength are needed.
• 0.12in wall thickness: A moderate wall that balances weight and rigidity for many light- to medium-duty structural applications.
• 72in length: A full 6 ft piece reduces joints and simplifies layout for longer runs in frames or supports.
• Hot rolled, carbon steel: Delivers weldability and overall toughness while keeping material cost reasonable for larger projects.

Who It's For

This tubing is aimed at fabricators, hobbyist metalworkers, contractors, and shop owners who need a reliable raw material for structural applications. It's particularly well suited to projects like small bridge components, building support members, appliance frames, or automotive fixtures where good strength and weldability are required.

It is less appropriate for finished decorative pieces that require precise cold-rolled surfaces or for applications demanding corrosion resistance without additional coating; buyers seeking stainless or galvanized sections for long-term outdoor exposure should consider specialty alternatives.

Pros & Cons

Pros

• Solid balance of strength and weldability makes it easy to join and integrate into welded frames.
• Customers report good overall quality and clean delivery with no visible rust, supporting reliable use out of the box.
• Value for money: hot rolled carbon steel keeps cost down for larger structural jobs.

Cons

• Hot rolled surface finish may not meet expectations for cosmetic projects without additional finishing.
• Not inherently corrosion resistant; external coating or paint is recommended for outdoor use.
