Long 1-1/2 In Angle Iron For Tables And Stands
Product: National Hardware N215-467 4060BC Solid Angle Iron Plain Steel
- Material: Hot-rolled plain steel; ASTM A36
- Size: 1-1/2 in x 48 in; strong for vertical or horizontal builds
- Best for: Workbenches, repair frames, and equipment stands needing sturdy reinforcement
Best for: Projects that require a longer single piece to span between supports. Limitation: Exterior use may require protective coating to prevent corrosion in harsh environments.
1-1/2 In By 1-1/2 In By 1/8 In Angle Iron, 24 In
Product: 1-1/2in x 1-1/2in x 1/8in (11 Gauge) Steel Angle Iron 24in
- Angle Thickness: 0.125 in
- Material: Steel
- Best for: Light-to-medium fabrication, small frames, braces
Caution: 11 gauge is thinner; plan for lighter load-bearing applications and consider reinforcements for high-stress joints.
1-1/2 In By 1-1/2 In By 1/4 In Angle Iron 24 In
Product: 1-1/2in x 1-1/2in x 1/4in Steel Angle Iron 24in
- Metal/Alloy Type: Steel
- Angle Width: 1.5 in
- Best for: Stronger braces and frames needing higher thickness
Choose this if you need increased thickness for load-bearing joints, but be mindful of additional weight and fabrication effort.
Rocaris Hot Rolled Steel Angle Iron 1.6″ X 1.6″ X 3/16″
Product: Rocaris Hot Rolled Steel ASTM A36 Angle Iron
- Exact Size: 1.6″ x 1.6″ x 12″ length
- Wall Thickness: 3/16″ (0.18″)
- Best for: Structural supports and braces requiring a square profile
Better for: Precise, square-angle applications where a 1.6″ leg is preferred over exact 1.5″ metric. Limitation: Shorter length requires joining for longer spans.
4 Pack 1.5×1.5×18″ Angle Iron, 11 Gauge
Product: Steel Angle Iron 1.5″x1.5″x18″ (4 Pack)
- Thickness: 11 gauge; Hot rolled
- Best for: Lightweight frames and small project bracing
Choose this 4-pack for value-conscious builders who need multiple identical pieces. Caution: Thicker gauges provide more strength but add weight and difficulty in cutting.
1-1/2″ x 1-1/2″ x 1/4″ Steel Angle Iron 72in
Product: 1-1/2in x 1-1/2in x 1/4in Steel Angle Iron 72in
- Thickness: 1/4 in
- Best for: Long-span frames and robust bracing
Best for: Projects needing longer length with higher thickness for structural stability. Limitation: Handling and transport require care due to weight and rigidity.
Buying Guide
Key purchase considerations help tailor choice to project needs:
- Size and thickness: For heavier loads, prefer 1-1/2″ x 1-1/2″ with 1/4″ thick walls. For lighter uses, 1/8″ or 11 gauge can suffice but reduces load capacity.
- Length: Longer pieces reduce the need for joints but require more storage and transport planning. Shorter lengths enable easier handling and custom fabrication.
- Material and finish: Hot-rolled A36 steel provides good weldability and strength. Exterior projects may benefit from protective coatings to resist corrosion.
- Interior vs exterior use: Exterior environments demand corrosion resistance or protective coatings; interior uses can leverage bare steel for welding efficiency.
- Fabrication compatibility: Consider cut, drill, and weld requirements when selecting thickness and length.
- Cost efficiency: Bundled packs or mixed-gauge options may save money on larger projects; factor in waste and cutoffs during planning.
FAQ
- What is the standard material for most 1-1/2 inch angle irons?
Most common options are hot-rolled plain carbon steel meeting ASTM A36 specifications, which offer good weldability and strength. - Can I use these for exterior outdoor frames?
Yes, but consider coatings or galvanization to prevent rust in moist or salty environments. - What thickness should I choose for a heavy-duty workbench?
1/4 inch (11 gauge) or thicker is preferable for high-stress joints and longer spans. - Are longer lengths better than shorter pieces?
Longer lengths reduce joints and simplify assembly, but require more storage and careful handling. - Will these angle irons cut easily in a home shop?
Yes, hot-rolled steel cuts with standard metal saws, but ensure proper safety practices and clamps for clean cuts. - Is 1-1/2 inch the only viable width?
For this keyword, 1-1/2 inch is common; other similar profiles exist, but 1-1/2 x 1-1/2 is the standard square angle for framing.
