Brian P. Verified BuyerCarbon Steel Round Bar 20MM .787" 1045 Precision Ground A108

I had been looking for 20mm carbon steel axles for a mini-forklift I am building for some time. For some reason all the pallet jack wheels I could find have 20mm axles and I needed to use those. I asked a friend and he immediately suggested Metals 'R' Us. I placed an order on a Sunday and had the material Wednesday. It fits perfectly! Now I have to spend a few days welding ...

About our carbon steel

Welding a frame, a gate, or a trailer? 44W is the structural workhorse here: angle, channel, flat bar, and plate that weld clean. Machining pins, bushings, or shafts? 1018 cold finished is the default. 1045 wears harder, 4140 is the high-strength pick, and 1144 Stressproof machines fast and stays straight. We also stock 1026 DOM mechanical tube plus A53 and A106 pipe.

It's our deepest section: round, flat, square, and hex bar, angle, channel, sheet, plate, pipe, and mechanical, square, and rectangular tube, with galvanized and precision-ground options on some lines. Type your length in inches and we cut to ±1/8″. Big structural lift? Request a quote and we'll price it.

Which steel grade do you actually need?

Match the grade to what happens to the part. Welded frames, brackets, gates, and general fab want 44W: it's the structural standard and the biggest pile on our rack. Parts headed to a lathe or mill want 1018 cold finished, it machines clean and holds size. Shafts and pins that see real load step up to 1045, and 4140 when the job gets serious. 1144 Stressproof machines beautifully and stays straight after the cut. For tube and pipe: 1026 DOM where precision matters, A53 and A106 for pipe work. Comparing 1018, A36, and 1045? Our steel grades guide puts them side by side, including why Canadian racks stock 44W where US charts say A36. Working from a US or European drawing? Our grade decoder translates 44W, A36, and S275 with the real numbers.

Hot rolled or cold finished?

Hot rolled comes with mill scale and looser dimensions; cold finished is smooth, accurate, and a little stronger from the cold work. The rule at the counter: if you're welding it into a frame, hot rolled 44W is fine and costs less. If the bar becomes a shaft, slides through a bushing, or meets a tolerance, buy cold finished 1018 and skip the cleanup.

What does steel cost?

It's the cheap one, and short pieces prove it. As of June 2026, a 12″ piece of 1/8″ x 1/2″ 44W flat bar runs $5.30 CAD and a 1″ piece runs $3.65. The saw time carries the small cut; the steel itself is nearly free. Prices update daily. Round bar, angle, tube, sheet, and drill rod all price the same way: type the length, see the number. For the bigger picture, our June 2026 Canadian metal price guide lists 17 real cuts across every material we stock.

How do you keep it from rusting?

Don't store it wet, and coat whatever lives outside. Oil is enough for shop tools and jigs, paint or powder coat for anything in the weather, and around salt it needs real coverage on every face, cut ends included. If the part can't be maintained where it's going, that's the moment to buy stainless instead of repainting steel every spring.

Beams, bar grating, and checker plate live in store, not online: here's what's on the racks.

Common questions

What steel grade is best for welding?
44W. It's made for structural welded work and it's the most common bar on our rack. 1018 welds fine too when the part also needs clean machining.
What is DOM tubing?
Drawn-over-mandrel 1026 tube: cold-worked for a uniform wall, accurate size, and good strength. It's the tube you want for sleeves, spacers, bushing shells, and rollers.
Will my steel arrive rusty?
It arrives as the mill finish you ordered: hot rolled carries dark mill scale, cold finished comes smooth and bright with a light oil. Neither is rust; both want a coating if they'll live outdoors.
Can I get a mill test report on steel?
Yes. MTRs are available on request for every standard line, any order size. Ask when you order or send your order number afterward.
