Product Description
Carbon Steel Rebar (short for reinforcing bar) is a ribbed steel bar used to strengthen concrete structures by providing tensile strength. Made primarily from carbon steel (low to medium carbon content), it is the most common type of rebar due to its cost-effectiveness, durability, and adaptability in construction.

Q: How to prevent carbon steel rebar from rusting?
A: Use epoxy coatings, galvanization, or ensure adequate concrete cover (min. 40mm).
Q: Can it be welded?
A: Yes, but high-carbon grades (e.g., Grade 75) require preheating to avoid cracks.
Q: Can I use ASTM rebar in non-US projects?
A: Yes, but check local codes (e.g., GB/T 1499 in China, BS 4449 in Europe).
Q: What's the difference between #5 and #6 rebar?
A: #5 = 15.9mm (1.55 kg/m), #6 = 19mm (2.23 kg/m) - thicker and stronger.
Q: Does ASTM rebar rust?
A: Uncoated (black) rebar can rust; specify epoxy-coated for corrosion resistance.
