Allstar Steel Tubing 1in x 2in x .120in Rectangle 7.5ft
Material and sizing: 1″ high by 2″ wide rectangle with 0.120″ wall, 7.5 feet long. This is a robust option for projects requiring a longer, continuous run of steel without frequent joins. Best for automotive frames, trailers, or structural braces where extra length minimizes joints. It’s a strong choice for buyers who need consistent dimensions and easier welding along the length.
Who it’s best for: DIY mechanics, racers, or fabricators needing a long, straight piece with steady early results. Why chosen: the 0.120″ wall balance provides stiffness without excessive weight. Limitation: the long 7.5 ft length may require handling care and precise cutting on-site.
Small Parts ALL22183-4 Unpolished Rectangular Tube 1″ x 2″ x 0.120″ 4′
Material and sizing: 1″ x 2″ rectangle, 0.120″ wall, 4′ length. This is a versatile option for lighter framing tasks, display fixtures, or small- to mid-scale projects. The finish is unpolished, which is typical for raw structural steel ready for fabrication.
Who it’s best for: hobbyists and light-duty fabricators needing a readily available, manageable length. Why chosen: standard 4′ piece simplifies cutting and transport. Limitation: unpolished finish may require surface prep for corrosion resistance in outdoor projects.
JEGS Mild Steel Tubing | Rectangular 1in x 2in x 0.120in 4 Feet
Material and sizing: A513 high-carbon steel, hot-rolled electric welded, 1″ x 2″ with 0.120″ thickness, 4 feet long. This option is designed for strength and durability in automotive or structural framing projects. Best for roll bars, cages, or other exposed structural work requiring reliable stiffness.
Who it’s best for: builders seeking a dependable material for roll cages or frames. Why chosen: A513 high-carbon steel provides good strength for demanding applications. Limitation: not stainless; risk of corrosion if exposed to harsh environments without protection.
1″ x 2″ Rectangular Steel Tube, 11 Gauge, 72″ Length
Material and sizing: 1″ x 2″ rectangular tube, 11 gauge (about 0.125″) wall, 72″ length. Mild steel A36 is common for general framing and DIY projects. Best for beginners or projects where standard fabrication methods are used.
Who it’s best for: beginners and hobbyists seeking a familiar, easy-to-work-with option. Why chosen: 11 gauge provides solid strength without excessive weight. Limitation: not as thick as heavier-walled alternatives for high-stress uses.
Hot Rolled Carbon Steel A513/A500 Rectangular Tubing 1″ x 2″ x 0.065″
Material and sizing: Hot-rolled carbon steel, 1″ x 2″ x 0.065″ wall, commonly used for structural framing and custom fabrications. This profile provides a good balance of strength and weight for bracing, frames, and DIY structures.
Who it’s best for: fabricators needing a durable, easy-to-weld option for structural projects. Why chosen: A513/A500 specifications ensure consistent performance in framing and machine guarding. Limitation: thinner wall than some 0.120″ options; consider load requirements before use in high-stress builds.
14ga (.078″) x 1″ x 2″ Steel Rectangle Tube, 7 Lengths
Material and sizing: 1″ x 2″ rectangle tube with 14ga (.078″) wall, available in multiple lengths. This option is suitable for lighter frames, display racks, or small-scale bracing where flexibility and ease of cutting are valued.
Who it’s best for: project builders prioritizing lighter weight and easier fabrication. Why chosen: thinner wall reduces weight while still providing sufficient rigidity for moderate tasks. Limitation: not ideal for high-load or outdoor long-term use without protective coating.
Buying Guide
Key considerations when selecting 2 x 1 steel tubing:
- Material type: Carbon steel offers strength and weldability; stainless steel provides corrosion resistance for outdoor or marine environments; hot-rolled options tend to be heavier and sturdier, while A513/A500 profiles emphasize structural strength.
- Wall thickness: Common options include 0.065″, 0.078″, and 0.120″. Higher wall thickness means greater stiffness and load-bearing capacity, but adds weight and cost.
- Length and handling: Longer lengths reduce joints but require larger tools and space for cutting. Shorter pieces are easier to transport and assemble but may need more connections.
- Finish and environment: Unpolished or raw finishes can corrode faster outdoors unless treated; consider primer, paint, or galvanization for outdoor use.
- Application fit: For roll cages, high-stress frames, or structural supports, prioritize thicker walls and carbon steel or A513 variants. For decorative or light-duty frames, thinner walls or stainless options may suffice.
- Compatibility: Ensure weldability and compatibility with your welding method (MIG/TIG) and any required coatings or treatments.
Practical comparison questions
- Which tubing is best for a corrosion-prone outdoor project? Look for stainless steel (316) or coated/hardened finishes.
- What’s the advantage of a thicker wall? Increased stiffness and load capacity, less deflection under load.
- Is longer length always better? Not necessarily; longer pieces reduce joints but require more space and precise cutting.
- When should I choose 11 gauge over 0.120″ wall? For lighter framing where weight matters, 11 gauge is suitable; for higher strength needs, 0.120″ is better.
- How important is exact weight? For mobile frames or trailers, weight can influence handling and fuel efficiency; thicker walls add weight.
FAQ
- What does 0.120″ wall mean? It is the thickness of the metal wall; thicker walls provide more strength.
- Can I weld all these tubes with standard welding methods? Yes, most are weldable with MIG or TIG processes, depending on the steel type.
- Are these tubes suitable for outdoor use? Some are; stainless options resist corrosion, while plain carbon steel may require protective coatings.
- Is a longer length always better for frames? It reduces joints but requires precise cutting and handling.
- Which option is best for beginners? Thinner-walled, easier-to-cut options, like 11 gauge or 0.078″ tubes, are often more beginner-friendly.
