Our Ka70 carbon steel coil is made according to the EN 10130 standard. The carbon content is controlled between 0.12 and 0.18, which makes it easy to weld and hard enough, and both are well taken care of.
According to the EN ISO 6892-1 standard, its tensile strength can reach 420 to 550 MPa, and the elongation is between 25 and 30. This means that it is strong enough to be used as a structural part, and it is also easy to process, and it is no problem to bend a bracket or make a frame.
The tight thickness tolerance of ±0.02mm across the entire coil, which beats the typical ±0.05mm you'll find elsewhere. For wholesalers, this translates to less material waste when cutting to size, saving you up to 8% on processing costs compared to standard carbon steel coils.
We offer two surface options: phosphatized (for better paint adhesion) and oiled (for rust protection during storage). The phosphatized finish creates a 2-4μm layer (tested to ISO 9717) that boosts paint durability by 30%-ideal for end products like agricultural machinery or steel furniture.
Our slitting lines handle widths from 150mm to 1300mm with ±0.15mm tolerance, using diamond-coated blades that maintain precision even after 100+ tons of cutting. We also offer edge deburring to a radius of 0.5mm max (per EN 10273), so there's no risk of sharp edges damaging your equipment during handling.
As a Chinese manufacturer with 10 years supplying to EU markets, we run 4 advanced rolling lines, each with a 120,000-ton annual capacity-total output hits 480,000 tons per year. Our in-house lab uses magnetic particle testing (per EN 10246-1) to check for surface defects, with 100% of batches passing inspection before shipment.
5% off on orders over 50 tons, plus free slitting and 20% off shipping costs.
If any Ka70 Carbon Steel Coil fails to meet EN 10130 mechanical specs or has more than 2 surface defects per m², we'll replace it within 5 days and cover the return shipping costs. We also lock prices for 45 days on bulk orders, so you won't get caught out by sudden market jumps.

Q: Do you have stock for standard-sized products?
A: Yes, we keep stock for most standard-sized pipes, flanges, and fittings to ensure quick delivery.
A: The MOQ for custom products depends on specifications, but generally starts from 1 pieces. For special cases, we can discuss further.
A: Yes, we accept small quantity orders. Even for trial orders, we'll provide the same quality and service as bulk orders.
A: Yes, we have tiered pricing for bulk orders. The larger the quantity, the more competitive the price.
