Mild steel is carbon steel with a carbon content of less than 0.25 percent. It is called mild steel because of its low strength and hardness.It includes most ordinary carbon structural steels and some high quality carbon structural steels, most of which are used for engineering structural parts without heat treatment, some are used for mechanical parts requiring wear resistance through carburizing and other heat treatment
our factory focus on small batch, special shape section steel bar, such as triangle, trapezoid, type L,pipeline guide, textile machinery pawl, can now produce nearly a hundred kinds of steel bars, a variety of special-shaped materials, high precision materials have been well received by users.Other products can control the molding accuracy within 0.05mm according to the drawing

FAQ
Q: I need a trapezoid or triangle that isn't in your list. What do you need to quote it?
A: Send a drawing with dimensions, tolerance, material grade, length, and quantity. A DXF or PDF helps. We check it against our existing dies – we have nearly a hundred profiles. If yours is close, we may only need a small die modification. If it's completely new, we quote the die cost and sample lead time separately. We can hold 0.05mm on the profile when the drawing calls for it.
Q: Who pays for the die, and can I keep it?
A: A new profile needs a die. We quote it separately from the steel. If you pay for the die, we can store it and run only your orders. If you want the die shipped to you after the run, we can arrange that. If you prefer not to own it, we can spread the cost into the piece price for larger batches. This is agreed before we start.
Q: Why should I buy a cold‑drawn shape instead of machining it from flat bar?
A: If you need long lengths with a consistent section, cold drawing is cheaper per meter and leaves a smooth surface. Machining from flat bar wastes material and adds tool marks. But for a one‑off or very small quantity, machining may be faster because there's no die. Send your quantity and we'll tell you which way is cheaper.
Q: Can I weld, bend, or carburize these mild steel profiles?
A: Yes. Carbon is under 0.25%, so welding is easy with standard low‑carbon electrodes. Bending is fine, though tight radii may need annealing first because cold drawing raises yield strength. For wear resistance, carburize or induction harden the working face. The core stays tough.
Q: For a textile machinery pawl or guide, should I use triangle or trapezoid?
A: Triangle self‑centers in a V‑groove and resists rotation. Trapezoid gives a wider flat contact face, so it wears longer when the load is one‑directional. For a pawl that hits a ratchet, trapezoid is usually better. For a guide that must stay centered, triangle. Send the mating part drawing and we'll suggest.
Q: What lengths do you ship, and can you cut to my size?
A: Triangles are standard 4m. We cut to your length. For long bars, straightness and twist matter more than the cut tolerance – we check them before bundling. Ends are protected, and bundles are strapped for export. If you need short pieces, we can cut and deburr.
