Sheet and Coil Processing

Processing of Stainless Steel Sheet, Coil, Strip and Plate:
Atlas Specialty Metals holds an extensive stock of bulk coils at its coil service centre, Atlas Metal Processors (AMP), located at Warragamba, NSW and offers a service to provide stainless steel sheet, coil and strip in a range of combinations of thickness, length, width and finish.
The following presents a guide to the capabilities of this service centre.
 
The Service Centre
The AMP service centre is 65000 square metre warehouse with modern processing equipment to convert large coils of stainless and aluminium into:
  • small coils
  • sheet and plate
  • slit strip
  • polished finishes; and 
  • scotchbrite finishes.

The latest technology has been incorporated in material handling equipment and information and communciations systems. These complement the state-of-the-art process management and customer service.
 
Sheet Cut to Length Line
A high speed line optimised for accurate cutting of standard or special length sheets. The line's capabilities and features are:
  • 0.3-2.00mm thickness
  • 200-1580mm width
  • side trim unit (minimum 5mm to 40mm maximum per side trim)
  • validation and feedback system to maintain consistency of length
  • stacker automatically sets to order requirement
  • Herr Voss leveller with automatic set-up feature which can be activated by gauge or coil identification number. This feature saves time and material on partly processed coils held in stock, as the leveller will set up the same parameters previously used
  • six high Herr Voss leveller enables the bottom surface to be treated with the same loving care as the top surface (most lines are only four high and a few are five high). Back up transfer marks are a thong of the past
  • High speed (up to 76m per minute)
  • All rolls in contact with the strip are coated to reduce the possibility of scratching
  • Double-sided PE application
  • Paper interleaving
  • 12.5 tonne input coil weights
Plate Cut to Length Line
This is a complete processing line that features shears, leveller and stacker. The line's capacilities and features include:
  • 500-2000mm processing width
  • 1.6-6mm stainless steel thickness and to 8mm for aluminium
  • 700-15000mm length
  • in-line double sided PE applicator and
  • 1-14.5 tonne input coil weights

Polishing Line
This line is an Imeas coupled polishing/brushing unit which provides polished and brushed finished including, No. 2, 3, 4, 5, 6, 6 fine, 7, 7 fine, Scotchbrite, Dulpo and custom finishes to meet most needs.

Polishing belts are formulated to provide a uniform polished surface. A roughness gauge is used to measure every coil to verify consistency of finish from coil to coil. The line's capabilities and features include:

  • 300-1580mm processing width
  • 0.3-2mm thickness up to 1580mm wide and up to 1220mm wide to 3mm
  • 7.5 tonne back tension coupled with a control system to optimise polishing conditions
  • rolls in contact with steel are coated to minimise the possibility of surface scratching
  • in-line double-sided PE applicator and paper interleaving and
  • 1-12.5 tonne input coil weights
Slitting Line
This line has been designed to provide maximum flexibility in producing high quality slit, narrow width material. The line's capabilities and features include:
  • 200-1580 processing width
  • 0.3-3mm thickness for stainless steel and 5mm maximum for aluminium
  • minimum 25mm slit width
  • computer-aided shimless slitting process to maintain accuracy of width
  • unique slit coil down-layer to minimise bore scoring
  • rolls in contact with steel or aluminium are coated to minimise the possibility of surface scratching
  • in-line double sided PE applicator and paper interleaving
  • conventional drag, tension rolls, bridle or combination of tension control
  • pull, loop, driven and combination slitting techniques and
  • 1-12.5 tonne input coil weights
Materials Handling and Packaging
Materials handling and packaging for stainless steel sheet, coil and strip are critical to minimising product damage. A range of innovative solutions has been installed such as coil-lifting devices that do not damage product, high-speed coil cars for transporting coils to the processing line and a down-layer for slit coil to minimise bore scratches.
One tonne coils are vertically packed with strong top and bottom pallets and a protective wrap of heavy corex is placed around the coil.
Sheet and plate are packed on strong wooden pallets and with secure strapping to withstand extensive handling and transportation.
Customised packing is provided subject to enquiry.
