STAINLESS STEEL PERFORATED ROUND HOLE SHEET: Perforated sheet are also punched in round hole shape of any grade in stainless steel whether it maybe 304, 304L, 316, 316L etc. Technical Detail: (i) Metal of the required sheet (ii) Grade of the required sheet (if applicable) (iii) Thickness of the required sheet (iv) Hole diameter of the perforated sheet (v) Pitch of the holes (if there any) (vi) Standard size availability : 1220 mm x 2440 mm Application: (i) Automotive (ii) Sugar Industries (iii) Agriculture (iv) Displays
What is Perforated Sheet? Perforated Sheet, also known as perforated metal, perforated plate, or perforated screen, that has been manually or mechanically stamped or punched to create a pattern of holes, slots, or decorative shapes. Materials used to manufacture perforated metal sheets include stainless steel, cold rolled close annealed steel sheet(CRCA), galvanized steel, brass, aluminum, copper, Monel, Inconel, titanium. Equipment used for perforation: 1) Rotary pinned perforation rollers 2) Die 3) Punch Presses 4) Manual Perforations or Laser Perforations whichever is been used. Applications: 1) Chemical & Energy 2) Automotive 3) Construction 4) Architectural
PERFORATED SHEET: Manufactured in CRCA, Mild Steel , Galvanized Iron, SS-304/316, Johnson Screens etc. in required types - Square, Round, Rectangular, Triangular Holes. Standard specification can be supplied as per your requirement. Perforated materials are used in a number of different applications for a variety of reasons. Used mostly as screens, filters, shields, and guards, perforated materials can control the passage of air, liquid, light, solids, heat, electromagnetic waves, and sound waves. Applications: 1) Automotive 2) Furniture and Accessories 3) Filters and Screens 4) Washing Machines 5) Food Processing and Pharma
TECHNICAL REQUIREMENTS ABOUT INDUSTRIAL WIRE SCREENS (ISO 14315): 1) Aperture Width (w): The distance between two adjacent warp or weft wires, measured in the projected plane at mid positions. 2) Wire Diameter (d): The diameter of the wire in the wire screen. 3) Pitch (p): (i) Distance between the middle points of two adjacent wires. (ii) Nominally the sum of the aperture width (w) and the wire diameter (d). 4) Warp: All the wires running lengthwise in the screen as manufactured. 5) Weft: All wires running crosswise in the screen as manufactured. 6) Number of apertures per unit length: The number of apertures which are counted in a row, one behind the other on a given unit length. 7) Open Screening Area (Ao): (i) Percentage of the surface of all the apertures in the total screening surface. (ii) Ratio of the square of the nominal aperture width (w) and the square of the nominal pitch (p) , i.e p = (w+d), rounded to a full percentage value: A0 = 100 x (w x w) / (w+d) x (w + d) 8) Firmness of industrial wire screen : Tension existing between the crossing of warp and weft wires and which, together with the interlocking, determines the firmness of the wire screen. Also note, that it is affected by the tensile strength of the material, by the relationship of (w) to (d), and by the type and the depth of the crimp. 9) Major blemishes: Production defects which significantly affect the aperture size or surface quality of the wire screen.
SQUARE MESH: Manufactured in Galvanized Iron, Stainless Steel, Brass, Copper as per ISI/BSS/ASTM with finest microns and meshes, Dutch Twilled Weaves also available.
