#1 · Best Overall

1. Speedway Motors DOM Roll Cage Tubing 1-5/8 Inch

• Dimensions: 84"L x 0.9"W
• Dimensions L x W: 84"L x 0.9"W
• Weight: 14 lb
• Material: Steel

Best for: 1-5/8-inch DOM cage tubing.

Why it ranks #1: Explicitly listed for roll cages, with DOM steel, 1-5/8-inch outside diameter, .120-inch wall, and a convenient 7-foot length.

Drawn-over-mandrel steel with a 1-5/8-inch outside diameter and .120-inch wall gives this Speedway Motors tube a clearly specified profile for roll cage and chassis fabrication. The 84-inch section also provides a defined seven-foot stock length for planning cuts and positioning within a build.

DOM construction is listed for consistent wall thickness and structural strength, useful details when selecting material for a fabrication plan. The 1.625-inch outside diameter and .120-inch wall let buyers compare this tube with common roll cage specifications, while its 84-inch length sets a clear stock limit for layout. Listed applications include roll cages, roll bars, race car chassis, bumpers, and nerf bars; the tube is straight stock, so bends are not part of the supplied description.

Skip it if you need pre-formed bends with the tubing; Khaos Motorsports lists 1.5-inch mandrel bends alongside short tube lengths.

Choose this for cage, chassis, or related fabrication calling for 1-5/8-inch DOM tubing with a .120-inch wall. It is a straight 84-inch section, so account for any bending and cutting needed by the layout.

#2 · Best 1-3/4-Inch DOM Option

2. Speedway Motors DOM Tubing 1-3/4 Inch

• Dimensions: 84"L x 1.8"W
• Dimensions L x W: 84"L x 1.8"W
• Weight: 13 lb
• Material: Steel

Best for: DOM tubing for cage builds.

Why it ranks #2: Purpose-described for roll cages and chassis, this 1020 DOM tube measures 1.75 inches in diameter with a .095-inch wall and 7-foot length.

1020 DOM steel is the defining feature of this seven-foot Speedway Motors tube, giving fabricators a specified material and uniform wall thickness for roll cage and chassis work. Its 1.75-inch outside diameter and .095-inch wall help buyers compare the section against a project's required tubing dimensions.

Drawn-over-mandrel 1020 steel is listed for reliable strength and uniform wall thickness, a useful specification when selecting tubing for fabrication. At 84 inches long, this pre-cut piece offers a defined length for a cage repair or custom build without requiring the buyer to choose among lengths on this listing. Speedway also identifies roll bars, bumpers, and nerf bars as uses, so the tube can serve more than one fabrication task when dimensions suit.

Skip it if you need a .120-inch wall; Speedway Motors Round DOM Roll Cage Tubing in 1-5/8-inch diameter lists that thickness.

Choose this for a cage or chassis project calling for 1.75-inch, .095-inch-wall 1020 DOM steel in a seven-foot section. Its stated dimensions are the key boundary: make sure they match the fabrication plan before cutting.

#3 · Best Pre-Notched Option

3. Speedway Motors Mild Steel Roll Cage Tubing

• Dimensions: 84"L x 2"W
• Dimensions L x W: 84"L x 2"W
• Weight: 14 lb
• Material: Steel

Best for: Pre-notched cage fabricators.

Why it ranks #3: Made specifically for roll-cage applications, this HREW 1020 tube has a 1-3/4-inch diameter, .109-inch wall, 7-foot length, and pre-notched sections.

Pre-notched sections are the most distinctive feature of this Speedway Motors tube, helping cage fabricators work from tubing that already has notches where needed. Its 1-3/4-inch outside diameter and .109-inch wall give buyers specific dimensions to match against their project requirements before cutting and fitting.

The HREW 1020 mild steel construction identifies the material, while the 84-inch length gives a seven-foot section to plan around for cage work. Pre-notched tubing can reduce some notch-preparation steps where the supplied notches suit the layout; it does not remove the need to check each joint and fit. The 1-3/4-inch outside diameter and .109-inch wall are useful selection details when coordinating this piece with a fabrication plan.

Skip it if you need DOM tubing or a .095-inch wall; Speedway Motors Round DOM Roll Cage Tubing is listed with that wall thickness.

This suits fabricators whose cage plan calls for 1-3/4-inch HREW 1020 tubing with a .109-inch wall and who can use pre-notched sections. Check the notch locations and dimensions against the intended joints before fabrication.

4. Allstar Performance DOM Tubing 1-5/8 Inch

• Dimensions: 90"L x 1.63"W
• Dimensions L x W: 90"L x 1.63"W
• Weight: 4.6 lb
• Material: Steel

Best for: 1-5/8-inch DOM fabricators.

Why it ranks #4: This 7.5-foot Allstar DOM tube shares the 1-5/8-inch diameter and .120-inch wall of a common cage-tubing format, though the description is less cage-specific.

This Allstar Performance tube pairs a 1-5/8-inch diameter with a .120-inch wall in round DOM steel, giving builders three key specifications to compare with a cage or chassis plan. Its 7.5-foot, 90-inch length provides a longer stock section than a seven-foot tube.

The round DOM construction and .120-inch wall are clearly named, helping buyers distinguish this tube from listings that specify mild steel without identifying DOM. A 1-5/8-inch outside diameter and 90-inch length give fabricators concrete dimensions for laying out a roll cage or related assembly before cutting. Allstar identifies it as steel tubing; the supplied information does not list notches or bends, so plan for the fabrication steps needed for the chosen layout.

Skip it if you need a 1-3/4-inch outside diameter; Speedway Motors Round DOM Roll Cage Tubing is listed at that diameter.

Consider this Allstar section when your fabrication plan calls for 1-5/8-inch round DOM steel with a .120-inch wall and 90 inches of stock. Its diameter is the main fit boundary, so check that specification against the design.

5. Khaos Motorsports Tubing and Bends

• Weight: 18 lb

Best for: Go-kart bend-and-tube projects.

Why it ranks #5: The assortment combines 1.5-inch A513-T1 HREW tube pieces with multiple 45- and 90-degree mandrel bends for go-cart frames and roll cages.

A combination of 1.5-inch mandrel bends and straight tubing distinguishes this Khaos Motorsports offering, giving go-kart and roll-cage fabricators both curved and straight pieces to work into a layout. The listed bends include multiple 45- and 90-degree pieces, alongside tubing with a .095-inch wall.

The supplied description lists multiple 45-degree and 90-degree, 1.5-inch mandrel bends, plus two 24-inch lengths of 1.5-inch-OD tubing. That mix can support layouts needing both turns and straight runs, rather than a single straight stock section. The tubing is identified as A513-T1 HREW with a .095-inch wall and 1.310-inch inside diameter. Khaos lists roll cages and go-kart frames among the uses; the bend angles and lengths should suit the intended layout.

Skip it if you need a continuous seven-foot straight tube; Speedway Motors Round DOM Roll Cage Tubing is listed in a seven-foot length.

This is aimed at go-kart frame and cage fabricators who can use both 1.5-inch bends and short straight sections. Its two 24-inch tube lengths make it a poor fit when the layout calls for long, uninterrupted stock.

6. Generic DOM Steel Tube 2 Inch

• Dimensions: 2"L x 2"W
• Dimensions L x W: 2"L x 2"W
• Material: DOM Steel Tubing

Best for: Custom-length DOM projects.

Why it ranks #6: A 2-inch OD, 1/8-inch-wall DOM tube could suit a build calling for those dimensions, but the listing provides no clear fixed cut length.

Custom lengths available upon request set this seamless DOM tube apart for fabricators whose layouts need a chosen stock length. The listed 2-inch outside diameter, 1/8-inch wall, and 1.75-inch inside diameter make its dimensions easy to compare with a project specification before ordering.

The seamless mild-steel DOM construction is paired with a 2-inch outside diameter and 1/8-inch wall, giving buyers a defined round-tube specification for fabrication. Its listed 1.75-inch inside diameter makes the wall relationship explicit for planning adjoining parts or clearances. Length tolerance is stated as plus or minus 1/8 inch, and custom lengths are available upon request, so length selection is part of the buying workflow rather than a stated fixed seven-foot format.

Skip it if you need a clearly listed seven-foot section; Speedway Motors Round DOM Roll Cage Tubing comes in an 84-inch length.

This suits a fabricator seeking seamless DOM mild-steel tubing in a 2-inch diameter and able to select or request a length. Confirm the requested length and dimensional requirements as part of the order planning.

7. Allstar Performance Mild Steel Tubing 1-1/2 Inch

• Dimensions: 90"L x 1.5"W
• Dimensions L x W: 90"L x 1.5"W
• Weight: 12.4 lb
• Material: Low Carbon Steel

Best for: Thick-wall 1.5-inch tubing.

Why it ranks #7: This 7.5-foot low-carbon-steel round tube has a .120-inch wall, but its listing does not specifically identify roll cages as an application.

A .120-inch wall on 1-1/2-inch mild steel tubing is the key specification of this Allstar Performance section, giving fabricators a defined combination of diameter and wall thickness to evaluate for a project. The 7.5-foot length provides a longer single piece than the listed seven-foot options.

This round low-carbon steel tube measures 90 inches long, so its 7.5-foot section gives a fabricator a defined stock length to lay out before cutting. The 1-1/2-inch outside diameter and .120-inch wall let buyers compare both dimensions with their cage or chassis plan rather than relying on diameter alone. Allstar identifies the product as mild steel round tubing, but the supplied details do not specify a DOM construction or pre-notched ends.

Skip it if you require specified DOM construction; Allstar Round DOM Steel Tubing is listed as DOM in a 1-5/8-inch diameter.

This fits fabricators seeking a 90-inch round mild-steel section with a 1-1/2-inch diameter and .120-inch wall. Treat its listed material and dimensions as the selection boundary, especially if your plan specifies DOM tubing.

8. Allstar Performance Mild Steel Tubing 1-1/2 Inch .095

• Dimensions: 90"L x 1.5"W
• Dimensions L x W: 90"L x 1.5"W
• Weight: 11 lb
• Material: Steel

Best for: 1-1/2-inch mild-steel tubing.

Why it ranks #8: A 7.5-foot round mild-steel tube with a 1.5-inch diameter and .095-inch wall; the product information does not specifically confirm cage use.

This Allstar Performance section combines a 1-1/2-inch outside diameter with a .095-inch wall in mild-steel round tubing, giving fabricators a clearly identified size for comparison with a cage plan. Its 7.5-foot length provides 90 inches of stock for laying out cuts.

The 90-inch length gives builders a defined section to plan around, while the round profile and 1-1/2-inch outside diameter provide a familiar shape and size for fabrication layouts. A .095-inch wall distinguishes it from thicker options, allowing buyers to compare the exact specification their project calls for. The listing identifies mild steel but does not specify DOM construction, so fabricators who require DOM should treat that as a material-selection boundary.

Skip it if you require specified DOM construction; Speedway Motors Round DOM Roll Cage Tubing is identified as DOM steel.

This suits buyers seeking a 90-inch round mild-steel tube with a 1-1/2-inch diameter and .095-inch wall. If a fabrication plan specifies DOM, the listing's mild-steel description does not establish that construction.

9. Speedway Motors Chromoly Chassis Tube

• Dimensions: 73.1"L x 1.5"W
• Dimensions L x W: 73.1"L x 1.5"W
• Weight: 7 lb
• Material: Chromoly

Best for: 4130 chromoly chassis work.

Why it ranks #9: The 4130 chromoly tube is described for cages and chassis, but its 1.25-inch diameter and .065-inch wall differ from the larger listed cage-tube options.

4130 chromoly steel is the defining material in this Speedway Motors tube, giving chassis fabricators a specified alternative to the mild-steel options in this roundup. The 1-1/4-inch outside diameter and .065-inch wall identify a precise, seven-foot section for comparing with a fabrication plan.

The 4130 chromoly construction is listed for demanding racing and fabrication applications, while the 1.25-inch outside diameter and .065-inch wall let buyers check the tube against their chosen chassis dimensions. Its pre-cut seven-foot length can reduce initial measuring and stock preparation for a build or repair. Speedway also names roll cages, race car chassis, roll bars, bumpers, and nerf bars as uses; the section's smaller diameter sets an important fit constraint.

Skip it if you need a 1-1/2-inch diameter; Allstar Performance Mild Steel Round Tubing is listed in that size.

This is for builders whose plan calls for 1.25-inch, .065-inch-wall 4130 chromoly in a seven-foot section. Its material and comparatively small listed diameter are central fit considerations for cage or chassis work.

#10

10. Allstar Performance Rectangular Steel Tubing

• Dimensions: 90"L x 2"W
• Dimensions L x W: 90"L x 2"W
• Material: Steel

Best for: Rectangular steel fabrication.

Why it ranks #10: Its 2-by-3-inch rectangular profile does not match the round tubing format of the other cage candidates, making it the weakest fit for this search.

A 2-by-3-inch rectangular profile differentiates this Allstar Performance steel tube from the round tubing options, giving fabricators a non-round section for projects that specify that shape. Its .083-inch wall and 7.5-foot length provide additional dimensions to check against the intended layout.

The 90-inch length supplies a defined 7.5-foot section to measure and cut for a fabrication project. Its rectangular 2-by-3-inch profile and .083-inch wall are the key selection details, making it distinct from round roll cage tubing and relevant only when the design calls for rectangular steel. Allstar lists the product as steel tubing, but the supplied information does not identify DOM construction or round geometry; those distinctions matter when matching a cage plan.

Skip it if you need round cage tubing; Allstar Round DOM Steel Tubing is a round option with a 1-5/8-inch outside diameter.

This fits fabricators whose project specifically calls for rectangular 2-by-3-inch steel with a .083-inch wall. For a roll cage plan specifying round stock, its rectangular profile is the key boundary to consider.
