Vous soudez un cadre, une barrière ou une remorque? Le 44W, c'est le cheval de trait structural ici: cornière, profilé en U, barre plate et plaque qui soudent propre. Vous usinez des goupilles, des bagues ou des arbres? Le 1018 fini à froid est le choix par défaut. Le 1045 résiste mieux à l'usure, le 4140 est le choix haute résistance, et le 1144 Stressproof s'usine vite et reste droit. On tient aussi le tube mécanique DOM 1026 ainsi que le tuyau A53 et A106.

C'est notre section la plus garnie: barre ronde, plate, carrée et hexagonale, cornière, profilé en U, tôle, plaque, tuyau, et tube mécanique, carré et rectangulaire, avec des options galvanisées et rectifiées de précision sur certaines lignes. Tapez votre longueur en pouces et on coupe à +/- 1/8 po. Un gros lot structural? Demandez une soumission et on va le chiffrer.

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 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.

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.

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.
