Technical characteristics for a perforated product

Besides its basic features, e.g shape and dimension of the holes, a perforated product is defined by a number of technical characteristics as listed below.

• Overall length and width of the sheet / coil
• Length and width of the perforated areas and unperforated margins
• Flatness 
• Squareness
• Surface aspects: free of oil, free of scratches 
• Burrs on holes and shearing burrs 
• Broken pitches and missing holes

The requested range of tolerances will strictly depend on the technical needs of each specific application. Please note that the requested tolerances affect the complexity of the manufacturing process of the perforated products and therefore their final costs.

All these issues must be considered and their acceptable tolerances quantified and approved during the first negotiation process.
RMIG has the knowledge and experience to assist and actively participate in that process whatever application and complexity level. Please contact us for any additional information you may require: .
