Precision rolling is not something that can be rushed or outsourced without consequence. At Special Metal Alloys, we have refined our cold rolling capabilities across generations of technical expertise, giving you access to in-house production that covers a wide range of alloys and gauges under one roof.
Our Sendzimir and 3/4-Hi rolling mills allow us to reduce strip to the lightest gauges while maintaining tight thickness tolerances and consistent flatness. Rolling in-house means you benefit from tighter process control, faster turnaround, and direct technical support with no third-party uncertainty in the supply chain.
Rolled Strip Size Ranges:
The edge condition of your strip coil directly affects how the material performs in your production process. Our precision slitting lines cut strip to your required width at finished gauge and temper, with full control over edge profile, coil inner diameter, coil outer diameter, interleaving, and winding method.
Available Edge Conditions:
| Edge Type | Width | Thickness |
| No. 1 Round Edge | Up to 38mm | 0.178mm – 1.575mm |
| No. 3 Slit Edge | From 0.5mm | 0.023mm – 3.175mm |
| No. 5 Square Edge | Up to 57mm | 0.102mm – 1.575mm |
| Broken Corner | Up to 89mm | 1.575mm – 3.175mm |
Slit Coil Size Ranges:
Whether your process involves stamping, deep drawing, roll-forming, or fine blanking, we will specify the right edge condition for your application.
Dimensional consistency across the full coil width is critical for forming and stamping operations. We offer:
Tension levelling is also available to achieve superior flatness, reducing shape defects that can interfere with downstream processing.
We customise temper to each customer’s specification, from drawing quality and coining tempers through to extra full hard. If your application demands a non-standard temper, our technical team will work with you to develop the right solution.
Standard camber tolerances comply with commercial specifications. Tighter tolerances are available upon request.
Strip coil can be annealed under a range of controlled atmospheres from full anneal to stress relieving giving you precise control over mechanical properties and microstructure. This ensures the material you receive behaves predictably in your process, every time.
Quality is not assumed at Special Metal Alloys it is verified. Our testing capabilities are designed to give you full confidence in the material before it reaches your facility.
Every test is traceable, and full material certification is provided with each order.
Our stainless steel strip coil and foil is supplied to meet a wide range of industry and international specifications, including:
Whether you operate in a highly regulated sector such as aerospace or nuclear, or require material certification for medical device manufacturing, our documentation and standards compliance supports your quality assurance process.
When your production process requires surface protection, lubrication, or a functional finish, we offer a range of coatings and plating options applied directly to the coil — removing the need for you to manage additional processing steps or third-party suppliers.
Pre-plated strip is available for applications where surface functionality is critical. We work with trusted processing partners to supply fully finished coil, reducing complexity in your supply chain and ensuring consistent surface quality across every order.
