Cold drawn steel profiles are precision steel products manufactured through a cold-drawing process at room temperature. This process significantly improves dimensional accuracy, surface smoothness, and mechanical properties compared to hot-rolled steel. They are widely used in machinery manufacturing, construction structures, automotive components, and precision equipment.

Frequently Asked Questions (FAQ)
Q
What is your minimum order quantity (MOQ)?
For cold-drawn steel profiles, we usually offer two purchasing options - LTL (less than truckload) and bulk order, starting from 2 tons. The specific quantity can be discussed.
Q
What is your delivery time?
For customized product orders, we can arrange shipment within 30 days after receiving the deposit.
Q
What are your payment terms?
Normally 30% T/T deposit in advance, and the balance against the copy of the Bill of Lading.
Q
Will carbon steel bars rust?
Yes. Carbon steel bars can rust in humid environments. Coating, galvanizing, or heat treatment can improve corrosion resistance.
Q
What are the common applications of carbon steel bars?
Common applications include building structures (rebar, support rods), mechanical parts (shafts, bolts), and tools (cutting tools, drill bits).
Q
What should be noted when welding carbon steel bars?
- Low carbon steel: easy to weld, but avoid overheating.
- High carbon steel: prone to cracking during welding; preheating and post-heat treatment are recommended.
