As manufacturing demands continue to evolve, precision matters, especially when every inch of material and every minute of production impacts your bottom line.
That’s why manufacturers are turning to advanced coil processing techniques, such as multi-blanking and cut-to-length (CTL). These coil processing techniques meet demanding specs while reducing waste, delays, and secondary processing.
At Alliance Steel, our state-of-the-art technology combines both capabilities into one high-efficiency system.
Whether you’re in the automotive, construction, or material handling industries, understanding how these processes work and how they’re evolving can give you a competitive edge when sourcing your steel blanks.
Here’s what you need to know.
What Is Cut‑To‑Length?
Cut‑to‑length (CTL) is the process of cutting coiled steel into flat sheets of predetermined length. It’s ideal for manufacturers who need consistent, flat, and burr-free blanks that meet exact specifications.
Alliance Steel’s cut‑to‑length line features a grip-feed system with non-marking grippers that securely guide material into the shear. This system not only prevents slippage but also automatically squares the strip, resulting in best-in-class length and squareness tolerances, ±0.010″ for length and ±0.0625″ for squareness.
What Is Multi‑Blanking?
Multi‑blanking is a high-efficiency metal processing technique that combines slitting and cut-to-length operations into a single pass. In simpler terms, it takes a master coil and turns it into multiple blanks of custom widths and lengths.
Using a combination of shearing, slitting, and stacking, multi‑blanking allows manufacturers to produce highly accurate sheet sizes with minimal waste.
At Alliance Steel, we maintain strict dimensional tolerances to ensure each blank is production-ready, requiring little to no secondary processing.
The system’s single-point shear blade clearance adjustment allows for cleaner cuts and delivers consistent edge quality.
Why Squareness and Flatness Matter
Squareness and flatness aren’t just nice-to-haves; they’re essential. When you’re welding, stamping, or assembling parts, a slight deviation in squareness can snowball into serious production issues. Poor flatness can lead to part distortion, alignment problems, or even equipment damage during forming or punching.
By delivering blanks that are consistently flat and square, Alliance Steel helps ensure seamless transitions from raw material to finished product, saving you time, labor, and headaches on the shop floor.
Why Combine Multi‑Blanking and CTL?
At Alliance Steel, our equipment combines multi-blanking and cut-to-length into a single, continuous process.
The result?
A streamlined production flow that saves time and reduces costs without compromising precision.
Key benefits include:
- Increased efficiency – Cut multiple blanks from a single coil pass, reducing handling and production time.
- Cost savings – Maximize raw material usage and reduce waste.
- Flexibility – Produce various blank sizes in one run with minimal tooling changes.
- Consistency –Controlled blade clearance and feeding systems maintain tight tolerances.
- Improved throughput – Reduced changeover times = more uptime.
- Smart stacking and sorting – Blanks exit the line organized and ready for packaging or production.

How It Works: Step‑By‑Step Process
- Uncoiling & Leveling
- The master coil is unwound and passed through a precision leveler to remove internal stress and imperfections.
- Slitting (Multi‑Blanking)
- Slitting heads divide the coil width into multiple strips based on specified dimensions.
- Feeding & Squaring
- The grip-feed system aligns the material with non-marking grippers, maintaining tension and squareness.
- Shearing (Cut‑To‑Length)
- Material is cut to the exact length, with tolerances held to ±0.010 inches.
- Stacking & Sorting
- Finished blanks are stacked cleanly, ready for packaging, shipping, or further processing.
