Evecad 1″ x 1″ Aluminum Tube
The Evecad square aluminum tube is built from 6063-T6 aluminum, offering good strength and corrosion resistance for outdoor or indoor fencing projects. The tube measures 1″ x 1″ with a 1/8″ wall thickness, and its seamless square profile supports clean, precise construction. It ships in a 48″ length, suitable for gates, frames, or fence components where lightweight, durable metal is preferred.
OnlineMetals Aluminum 6063-T52 Square Tubing
This square tubing is made from 6063-T52 aluminum, known for corrosion resistance and good weldability. It is listed as ASTM B221 compliant and offers a 1″ x 1″ cross-section with a 0.062″ wall. Heat-treated for increased strength, it is well-suited for railings, frames, or fence accessories where lightweight metal is advantageous yet requires solid structural integrity.
Gisafai Aluminum Square Tubing, 1″ OD
Gisafai offers two aluminum tubes in a 1″ outer diameter with a 0.12″ wall, 24″ long. Made from 6061 aluminum for durability and corrosion resistance, these tubes come in a pack of two, enabling quick setup for short fencing segments, frames, or decorative outdoor features. The precise dimensions and easy cutting/welding options support flexible installation.
80/20 9701 Anodized Aluminum Tube
This 1-1/2″ x 1-1/2″ aluminum square tube from 80/20 features a clear anodized finish and 0.328″ holes on 1.5″ centerlines, with a 0.125″ wall. It’s a robust option for modular framing systems, fence assemblies, or DIY projects requiring precise hole placement for bolting or attaching components. The anodized surface enhances wear resistance and appearance in outdoor settings.
Shapiro A36 Hot Rolled Steel Square Tubing
Shapiro Metal Supply offers a 4″ x 4″ hot rolled steel square tubing with a 0.120″ wall thickness. A36 carbon steel provides good weldability and strength, making it a solid choice for heavy-duty fence frames or gate components where higher load capacity is required. The hot-rolled surface is compatible with various fabrication processes and can be finished to match project aesthetics.
OnlineMetals Hot Rolled Steel Square Tubing
This option is ASTM A-36 compliant, with a 1-1/2″ x 1-1/2″ cross-section and a 0.12″ wall. It is hot rolled to meet specified dimensions and provides solid structural support for fencing, frames, or scaffolding. Steel’s rigidity and higher weight can contribute to a more robust fence system, especially in windy or high-traffic areas.
MorningRo Square Sign Post Tubing
MorningRo produces a 6-foot-long, 2″ wide galvanized iron square post with a perforated design. While primarily a sign post, its square profile and galvanized coating make it a relevant option for fence framing or gate supports in lighter-duty outdoor projects. The 0.08″ thickness offers a balance between strength and affordability, with corrosion resistance from the galvanized finish.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Aluminum options provide lighter weight and superior corrosion resistance, ideal for outdoor fences. Steel (A36) offers higher strength for heavy-duty applications but is heavier and may require protective coatings.
- Wall thickness and strength: Thicker walls increase rigidity and load-bearing capacity. For fencing, a balance between weight and strength is important, especially for long runs or gates.
- Cross-section size and compatibility: Common sizes include 1″ x 1″ and 1-1/2″ x 1-1/2″ profiles. Ensure the tubing matches your hardware, fittings, and mounting methods. Anodized or coated finishes impact compatibility with other components and aesthetics.
- Length and cutting needs: Longer tubes reduce joints but may require on-site shortening. Consider how often you will cut or weld and whether you have access to the needed tools.
- Hole patterns and modular systems: Tubes with pre-drilled holes (as in the 80/20 option) enable adjustable connections and easier assembly for fence gates, frames, or modular fences.
- Cost vs. performance: Aluminum tends to be more expensive than steel but offers corrosion resistance and lighter weight. For high-traffic outdoor fences, steel may deliver better durability at a lower material cost.
- Fabrication compatibility: Check weldability, forming, and finishing requirements. Aluminum requires different welding parameters than steel; anodized finishes affect welding unless properly prepared.
Selecting the right metal square tubing for a fence project depends on whether the priority is light weight and corrosion resistance (aluminum) or maximum strength and load capacity (steel). Consider climate, wind loads, maintenance expectations, and installation convenience when evaluating options.
