Fori oblunghi

Product catalog summary

Overview: The document provides technical specifications and nomenclature for different types of perforations, specifically focusing on elongated and rectangular holes. It includes details on the arrangement, dimensions, and materials used for these perforations.

Specifications:

Elongated Holes: These are available in alternated and even dispositions. Key parameters include hole width (a1), hole length (a2), full space between edges (c1), full space between heads (c2), vertical pitch (p1), and horizontal pitch (p2). The percentage of empty space is calculated using the formula: (a1 x a2 – 0.2 a1) / (p1 x p2).
Materials: Perforations are produced in materials such as iron A00, stainless steel, brass, and aluminum, with standard dimensions of 1000 x 2000 mm. Custom sizes and perforations can be made according to client specifications.

Procedures:

Production: Elongated holes are produced in standard sizes and are typically available in stock. Custom orders are also accepted for specific dimensions and arrangements.
Arrangement: Holes can be arranged alternately or in parallel to the longer or shorter sides of the sheet.

Standards and Recommendations:

Ensure accurate measurement of hole dimensions and pitches to maintain the desired percentage of empty space.
Consider material properties and thickness when selecting the type of perforation for specific applications.

Key Data:

Standard hole sizes include variations such as 2x20 mm, 3x20 mm, 4x20 mm, and others, with thicknesses ranging from 1 mm to 6 mm.
Rectangular holes are also available on request, with sizes like 1.50x20 mm and 4.50x20 mm.
