7. Speedway Motors Chromoly 1 x .095

• Dimensions: 84"L x 1"W
• Weight: 7 lb
• Material Type: Chromoly

Best for: Small-diameter 4130 projects.

Why it ranks #7: Its 4130 chromoly construction and .095-inch wall are specified, and the listing names roll cages, though its 1-inch diameter is smaller than leading options.

4130 chromoly in a one-inch outside diameter is the defining combination of this Speedway Motors tube, aimed at builders specifying that alloy for compact fabrication components. Its .095-inch wall and seven-foot pre-cut length give a clear dimensional package for roll cages, chassis, roll bars, bumpers, and nerf bars.

The 1.000-inch diameter and .095-inch wall provide precise dimensions to compare with a cage or chassis plan, while the 4130 chromoly material identifies the alloy. A seven-foot pre-cut section supplies useful continuous stock for allocating pieces across a build. The listing names roll cages and other motorsports applications, but does not state DOM construction or pre-notching, so those should not be assumed when planning joints or selecting tubing for a specified design.

Skip it if you need DOM construction in a smaller one-inch tube; Allstar Performance’s one-inch round DOM tubing is a direct construction-type alternative.

This fits builders who need 4130 chromoly tubing at one-inch diameter with a .095-inch wall and seven-foot length. Confirm those dimensions against the intended layout; DOM construction is not stated in its listing.

#8

8. Speedway Motors Chromoly 1.25 x .065

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

Best for: 1-1/4-inch 4130 chassis work.

Why it ranks #8: This 4130 chromoly tube is described for roll cages and chassis, but its 1.25-inch diameter and .065-inch wall are comparatively small among cage-specific options.

The 1-1/4-inch diameter sets this 4130 chromoly Speedway Motors tube apart from the group’s smaller one-inch options. A .065-inch wall and seven-foot pre-cut length add defined dimensions for chassis and roll-cage fabrication, with the listed alloy identifying the material for motorsports projects.

4130 chromoly construction and a 1.25-inch outside diameter establish the material and size for planning a chassis or cage component. The .065-inch wall is a precise specification to compare with the build requirements, while the seven-foot pre-cut length can reduce the need to prepare a longer raw section. Listed uses include roll cages, race-car chassis, roll bars, bumpers, and nerf bars. No DOM designation or pre-notch details are supplied, so joint preparation remains part of the builder’s work.

Skip it if your specification calls for a .095-inch wall at one-inch diameter; Speedway Motors’ 4130 one-inch tubing matches that wall dimension.

This is a candidate for chassis or cage fabricators specifying 1-1/4-inch 4130 tubing with a .065-inch wall. Its seven-foot length aids planning, but the wall must match the project’s requirements.

#9

9. Allstar DOM 1 x .120

• Dimensions: 48"L x 1"W
• Weight: 4.6 lb
• Material Type: Steel

Best for: Short one-inch DOM sections.

Why it ranks #9: It is DOM steel with a .120-inch wall, but the listing gives a 1-inch diameter and does not specifically identify roll cages as an application.

The four-foot length is the practical distinction of this Allstar Performance round DOM tube, limiting the amount of stock to handle when a project calls for a shorter section. Its one-inch outside diameter and .120-inch wall provide clear dimensions for smaller-scale fabrication work or components in a broader build.

This tube pairs a one-inch outside diameter with a .120-inch wall, giving fabricators a defined size for planning a component or matching a specified tube dimension. Its four-foot length is shorter than the seven-foot and 7.5-foot options in this group, which can make it easier to allocate when the project needs less continuous material. The listing identifies it as round DOM steel tubing, but does not state roll-cage-specific uses or provide notch details.

Skip it if you need a 1-3/4-inch primary cage tube; Speedway Motors’ 1-3/4-inch DOM tubing is a closer size match.

Consider this for a project calling for one-inch DOM tubing in a manageable four-foot section, especially when the specified .120-inch wall fits the plan. It is a small-diameter option, not a direct match for larger cage tubing.

#10

10. Allstar Mild Steel 1 x .065

• Dimensions: 90"L x 1"W
• Material Type: Steel

Best for: Long one-inch mild-steel stock.

Why it ranks #10: This 1-inch, .065-inch-wall mild-steel tube is described generally, without a stated roll-cage application, making it the least direct match.

At 7.5 feet, this Allstar Performance mild-steel round tube provides a long continuous section in a one-inch diameter. Its .065-inch wall identifies a relatively thin-wall specification within this selection, making dimensions central to deciding whether it suits a particular fabrication component or build plan.

The one-inch outside diameter and .065-inch wall let fabricators compare this tube with a project’s required dimensions before cutting. Mild-steel construction identifies its material, and the 7.5-foot length offers a continuous span for dividing into multiple planned pieces or covering a longer run. The product information names round tubing but does not specify DOM construction, chromoly, pre-notching, or roll-cage applications, so it is best treated as a dimension-specific fabrication option rather than assuming those properties.

Skip it if you require documented DOM tubing for cage work; Allstar Performance’s 1-5/8 x .120-inch DOM tube is explicitly identified as DOM.

This suits a fabricator seeking a long section of one-inch mild-steel round tubing with a .065-inch wall. Treat it as a dimension-specific material choice; the supplied listing does not establish DOM construction or cage use.
