Best Steel Tubing For Roll Cage: Compare 10 Options

#1 · Best Overall

1. Speedway Motors Mild Steel Tubing

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

Best for: Pre-notched 1-3/4-inch tubing.

Why it ranks #1: Designed for roll cages, this HREW 1020 mild-steel tube pairs a 1-3/4-inch outside diameter with a .109-inch wall and a 7-foot length.

Pre-notched sections are the defining convenience of Speedway Motors’ 1-3/4-inch, .109-wall HREW 1020 mild-steel tubing, helping a roll-cage fabricator work with prepared sections rather than starting every tube from an unnotched length. Its seven-foot format and stated diameter and wall thickness give builders concrete dimensions to plan around.

The HREW 1020 mild-steel construction gives this tube a named material specification, while the 1-3/4-inch outside diameter and .109-inch wall identify the dimensions for layout and fabrication planning. Pre-notched tubing can reduce preparation work where the supplied notches suit the build; the seven-foot length provides a defined piece to handle and cut as needed. Those dimensions are specific to this product, so compare them with the cage design before ordering.

Skip it if you need 4130 chromoly rather than HREW 1020 mild steel; Speedway Motors’ 1-inch chromoly tube is a different material option.

For a fabricator seeking pre-notched, 1-3/4-inch mild-steel tubing in a seven-foot piece, this offers defined dimensions and material. Check the notches, length, and wall specification against the planned cage before committing.

#2 · Best DOM Option

2. Speedway Motors DOM Tubing

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

Best for: Seven-foot 1-3/4-inch DOM.

Why it ranks #2: Purpose-listed for roll cages, this 1020 DOM tube offers a 1.75-inch outside diameter, .095-inch wall and a 7-foot precut length.

A 1.75-inch outside diameter paired with .095-inch wall thickness makes Speedway Motors’ seven-foot 1020 DOM tube a clearly dimensioned choice for roll-cage and chassis fabrication. Drawn-over-mandrel construction is specifically stated, giving builders a defined steel-tube type to consider when planning members and matching the material to a project.

The 1020 DOM construction is described as providing reliable strength and uniform wall thickness, linking its manufacturing specification to consistent fabrication planning. Its 1.75-inch diameter and .095-inch wall identify the cross-section, while the seven-foot pre-cut length gives the builder a fixed piece for measuring and cutting. The listed uses include roll cages, chassis, roll bars, bumpers, and nerf bars, so it can serve several named motorsports projects.

Skip it if you specify a .109-inch wall at 1-3/4 inches; Speedway Motors’ HREW 1020 mild-steel tube lists that dimension.

Consider this for a seven-foot, 1.75-inch DOM member in a roll cage, chassis, or related fabrication project. Its .095-inch wall is a key boundary, so verify the specified design dimensions.

• Dimensions: 48"L x 1.63"W
• Dimensions L x W: 48"L x 1.63"W
• Weight: 8 lb

Best for: Four-foot DOM steel sections.

Why it ranks #3: This round DOM steel tube specifies a 1.625-inch outside diameter and .120-inch wall, with a compact 4-foot length for fabrication.

Drawn-over-mandrel construction is the defining specification of Allstar Performance’s 1-5/8-inch, .120-wall steel tubing, supplied in a manageable four-foot length. That shorter stock format can suit a fabrication plan built around compact sections, while the stated diameter and wall thickness give buyers clear dimensions to compare with their design.

The DOM designation distinguishes this steel tube’s stated manufacturing type, while its 1.625-inch outside diameter and .120-inch wall give fabricators concrete measurements for fit and layout planning. At four feet long, it is a shorter piece to stage and cut than the listed 7.5-foot Allstar mild-steel tube. That can suit projects calling for shorter sections, though a longer run would require a different stock plan.

Skip it if you need a 7.5-foot mild-steel piece; Allstar Performance’s 1-5/8-inch x .120-inch round tubing is listed at that length.

This is for builders whose design calls for DOM steel in 1-5/8-inch diameter, .120-inch wall, and four-foot sections. Plan around the short stock length when laying out longer cage members.

• Dimensions: 90"L x 1.63"W
• Dimensions L x W: 90"L x 1.63"W

Best for: Long mild-steel tube stock.

Why it ranks #4: The 1-5/8-inch round mild-steel tube has a .120-inch wall and 7.5-foot length, though its listing does not identify a steel grade.

At 7.5 feet long, Allstar Performance’s 1-5/8-inch round mild-steel tube gives a fabricator a longer single piece than four-foot stock, which can help when planning extended runs. Its .120-inch wall specification and steel material identify the basic dimensions and material for a cage or other tubing project.

The 1-5/8-inch outside diameter and .120-inch wall provide useful fixed dimensions for design and fabrication planning, while the 7.5-foot length may allow a longer run before a cut or joint is needed. The listing identifies it as mild-steel round tubing, rather than DOM or chromoly, so material selection remains part of the build decision. Its straight round-tube format suits buyers who have a project plan calling for these specifications.

Skip it if you require a specified DOM tube; Allstar Performance ALL22140-4 lists DOM steel in 1-5/8-inch diameter and .120-inch wall.

This suits fabricators whose plans call for 1-5/8-inch, .120-wall mild-steel round tubing and a 7.5-foot piece. Buyers specifying DOM or chromoly should choose material expressly identified that way instead.

Why it ranks #8: This 4130 chromoly option is listed for roll-cage use and provides a 1-inch outside diameter, .058-inch wall and 7-foot length.

The .058-inch wall is the defining measurement of this Speedway Motors 1-inch, seven-foot 4130 chromoly tube, giving a fabricator a specific thin-wall option to evaluate for a roll cage or chassis project.
