The angle iron we stock

SteelFront sells five angle iron products. Two are hot-rolled structural angle in ASTM A36 steel. Three are roll-formed from flat steel strip. The table shows what each one is for.

Lengths for every product: 1′, 2′, 6′, 10′, 15′ and 20′. Lead times are taken from each product page and are counted before the order ships.

Angle irons by type: which one to buy

All five of our angle irons are cut to 1′, 2′, 6′, 10′, 15′ or 20′ and sold one piece at a time, so you can order a single bracket blank or a full cut list in the same cart.

• Welding a frame or support: structural A36 angle, unpunched, from 1″ x 1″ x 1/8″ up to 3″ x 4″ x 1/4″.
• Bolting without a drill: punched structural angle or punched roll-formed angle, both with .563″ holes on 2″ centers for 1/2″ bolts.
• Light framing and shelving: roll-formed angle, unpunched, in 1-1/2″ and 2″ legs.
• Garage door openers and tracks: garage door angle iron, punched on both legs for 3/8″ bolts.

Angle iron size and weight chart

Use this chart to estimate shipping weight, compare profiles, or check that a size will carry the load your engineer specified. Structural weights are the published nominal values for hot-rolled angle (AISC Shapes Database v16.0 for 2″ and larger; mill bar-size tables for 1″ and 1-1/2″). Roll-formed weights are the shipping weights in our catalog. For more sizes, see the full angle iron size chart.

Gauge thickness is the nominal Manufacturers’ Standard Gauge value for uncoated steel sheet. Punched angle weighs a little less than solid angle because of the steel removed at the holes. Hot-dip galvanizing adds zinc and a small amount of weight.

Angle iron buying guide

Structural or roll-formed?

Structural angle is hot-rolled at the mill to ASTM A36. It has a solid, slightly rounded inside corner (the fillet) and a minimum yield strength of 36,000 psi. Pick it for frames, supports, brackets, trailers and anything an engineer has sized by load. Roll-formed angle is bent from flat steel strip, so it has a sharper corner and a uniform gauge thickness. It is the type of angle most hardware stores sell. It works well for shelving, garage door opener mounts, light framing and bolt-together builds. Our guide to the types of angle iron compares the two in more detail.

Punched or unpunched?

Buy unpunched angle when you plan to weld, or when you need holes in places a standard pattern will not hit. Buy punched angle when you want to bolt parts together without a drill. Our 1/2″ bolt pattern uses .563″ (9/16″) holes on 2″ centers. Single punch has holes in one leg; double punch has holes in both legs. The hex nut and bolt sets are sized for these holes. The garage door angle uses a tighter 1″ spacing for 3/8″ bolts on both legs.

Raw, pre-galvanized or hot-dip galvanized?

Raw steel is ready to weld, prime or paint, and it is the lowest-cost option. Pre-galvanized roll-formed angle is formed from steel that is zinc coated before forming, which gives it a clean, even finish for indoor work and covered outdoor work. Hot-dip galvanized structural angle (offered on our punched structural angle) is dipped in molten zinc after it is made, which coats every edge and hole and lasts the longest outdoors. Read more in our galvanized angle iron guide.

Which length should I order?

Order the shortest stock length that covers your cut list. A 20′ piece gives the most usable steel per order but ships as a long, heavy item. 6′ and 10′ pieces are easier to handle. 1′ and 2′ pieces are handy for brackets, gussets and repairs. Shipments over 70 lb go by freight.

How to read an angle size

Angle iron is written leg x leg x thickness. A 2″ x 2″ x 1/8″ angle has two 2″ legs that are 1/8″ thick. Unequal-leg angle such as our 2″ x 3″ x 1/4″ has one 2″ leg and one 3″ leg. Engineering tables list the long leg first (L3 x 2 x 1/4), so the two names describe the same piece. Measure legs on the outside, from the heel (the back of the corner) to the toe (the end of the leg).

What angle iron is used for

• Tank batteries, catwalks and stairways: punched angle bolts to our walkway and stair parts and acts as the support, stringer or kick-plate backer.
• Shop and garage builds: workbench legs, shelving frames and garage door opener supports.
• Farm and ranch: gates, feeders, trailer racks and tank stands. See our agriculture parts page.
• Construction and fabrication: lintels, ledgers, frames, bracing and embeds. See parts for contractors.
• Industrial plants: equipment frames, guards and platform framing. See industrial catwalk parts.

Shipping

Angle iron ships from Hutchinson, Kansas to addresses in the United States. Lead times are listed on each product (3-5 business days for most angle). Orders over 70 lb ship by freight.

Frequently asked questions

What is angle iron?

Angle iron is a length of steel bent or rolled into an L shape with two legs at 90 degrees. Despite the name, modern angle iron is made of steel. It is also called steel angle, angle bar or L-angle.

What sizes of angle iron does SteelFront sell?

Structural A36 angle in 1″ x 1″ x 1/8″, 1-1/2″ x 1-1/2″ x 1/8″, 2″ x 2″ x 1/8″, 2″ x 3″ x 1/4″, 3″ x 3″ x 1/4″ and 3″ x 4″ x 1/4″; roll-formed angle in 1-1/2″ and 2″ leg sizes; and garage door angle in 1-1/4″, 1-1/2″ and 2″ leg sizes. All come in 1′ to 20′ lengths.

How much does angle iron weigh per foot?

Common sizes weigh 0.80 lb/ft (1″ x 1″ x 1/8″), 1.23 lb/ft (1-1/2″ x 1-1/2″ x 1/8″), 1.65 lb/ft (2″ x 2″ x 1/8″), 4.90 lb/ft (3″ x 3″ x 1/4″) and 5.80 lb/ft (3″ x 4″ x 1/4″). Multiply by the length in feet for the piece weight. A 20′ piece of 2″ x 2″ x 1/8″ weighs about 33 lb. See the angle iron size chart for more sizes.

What is the difference between structural and roll-formed angle?

Structural angle is hot-rolled A36 steel with a rounded inside corner and published strength values. Roll-formed angle is bent from flat steel strip, and has a sharper corner and a uniform gauge. Use structural angle for load-bearing work and roll-formed angle for lighter framing, shelving and bolt-together projects.

What size bolt fits punched angle iron?

Our standard punched angle has .563″ (9/16″) holes on 2″ centers, sized for 1/2″ bolts. The garage door angle is punched for 3/8″ bolts, with holes 1″ apart on both legs.

Is angle iron galvanized?

Not unless it is ordered that way. Raw angle iron is bare steel and will rust outdoors unless it is painted. SteelFront offers pre-galvanized roll-formed angle and hot-dip galvanized punched structural angle for outdoor and wet locations.

Can I buy angle iron cut to length?

Yes, in fixed stock lengths. Every SteelFront angle product comes in 1′, 2′, 6′, 10′, 15′ and 20′ pieces, so you can order close to the length you need without buying a full mill-length bar.

How strong is 2 inch angle iron?

It depends on the thickness, the span and how the load is applied, so no single number is correct. For reference, 2″ x 2″ x 1/8″ A36 angle has a minimum yield strength of 36,000 psi and an elastic section modulus of 0.129 in³ (AISC). Have an engineer size any angle that will support people or a structure.

Where is SteelFront angle iron shipped from?

From Hutchinson, Kansas. We ship to addresses in the United States. Most angle ships in 3 to 5 business days, and orders over 70 lb go by freight.

Do you sell angle irons in small quantities?

Yes. There is no minimum order. You can buy one 1′ piece or a stack of 20′ lengths, and every size shows its price before checkout. Orders ship from Hutchinson, Kansas, or you can pick up free at our plant.
