The Workhorse Steel You Can Build On
We’ve been rolling structural steel coils for over 15 years, and ASTM A1011 remains one of our most trusted materials. It’s not just about meeting specs—it’s about performing in the real world, where welds hold up, edges stay true, and projects finish on time. Whether you’re building a warehouse in Texas or a bridge in Southeast Asia, this steel delivers.
What makes it different? For starters, Grade 50 (345 MPa yield strength) gives you 40% more load capacity than standard A36—without adding weight. We’ve seen contractors switch and reduce beam sizes by one or two sections, cutting both material and labor costs. The chemistry is lean but smart: low carbon (0.26% max) keeps welding clean, while manganese (up to 1.65%) boosts strength. We’ve had fabricators run it through their CNC plasma cutters all day with minimal edge cracking, and welders praise the consistent penetration.
- Typical thickness range: 1.5mm to 25.4mm, but we’ve gone as thin as 1.2mm for specialty projects
- Widths from 600mm to 2,100mm, with precision slitting to minimize waste on narrow components
- Surfaces? Standard mill finish works fine, but pickled and oiled helps in humid climates or extended storage
Where It Earns Its Keep
This isn’t just “another steel coil.” We’ve shipped it for:
– Heavy haulers: Trailer frames that handle 50-ton loads with fatigue-resistant welds
– Farm equipment: Pivot arms and tillage frames where impact resistance matters
– Modular buildings: Pre-engineered structures using Grade 36 for easier forming
One customer in Brazil switched from A36 to A1011 Grade 50 for their grain silos. They cut steel weight by 15% while meeting the same wind and seismic loads—a win for both cost and safety.
Quality isn’t just checked, it’s tracked. Every coil comes with EN 10204 3.1 certification, and we can arrange third-party verification (SGS, BV) at the mill. Our ISO 9001:2015 process means you’re getting the same consistency whether it’s 10 tons or 10,000.
Why Work With Us?
Being a Chinese integrated steel mill gives you advantages: direct pricing, flexible MOQs, and full control over chemistry adjustments. Need tighter tolerances? We can do ±0.1mm on thickness. Want a custom edge? No problem. Just tell us what your project really needs—not just the textbook specs.
We know your time is money. So when you call, you’ll talk to an engineer who’s actually run a rolling mill, not just a sales script. Ready to discuss your next job? We’re here to help.
