Ambani Metals is an ISO-certified manufacturer and global exporter of high-precision perforated metal sheets based in India. Leveraging CNC turret punch presses, automated perforating lines, and in-house tooling facilities, we produce perforated sheets meeting stringent dimensional tolerances and flatness requirements demanded by international EPC contractors and OEMs.
Whether your operations require heavy-gauge screening plates for mineral processing, hygienic stainless steel sieve panels for pharmaceutical and food production, or architectural facade cladding with custom open-area ratios, our engineering team ensures uniform pitch, burr-free edges, and structural integrity across every production batch.
Our tooling capacity covers standard geometric patterns as well as bespoke perforated configurations engineered to your exact filtration, acoustic, or ventilation parameters.
The industry benchmark for mechanical strength and optimal airflow. Available in 60-degree staggered, 45-degree, and straight line patterns for filtration, sorting sieves, acoustic damping, and protective machine guarding.
Engineered for high-volume liquid drainage, grain sorting, seed grading, and solid-liquid separation. Features round-end or square-end elongated slots arranged in staggered or side-staggered orientations.
Designed for exterior facades, sunscreens, balustrades, ceiling panels, and partition walls. Combines aesthetic appeal with acoustic performance and daylight transmission management in anodized or powder-coated finishes.
Formed with raised textures, dimples, or anti-slip patterns integrated with drain perforations. Ideal for industrial catwalks, vehicle floorings, ramp steps, and heat dissipation covers requiring enhanced structural stiffness.
Offers maximum open area compared to round perforations, providing unobstructed ventilation and sight lines. Widely used in HVAC ventilation grilles, electrical equipment enclosures, and storage racks.
Sheets manufactured with custom blank margins, bolt mounting holes, notched corners, roll bending, or edge folding to suit seamless drop-in assembly at the customer plant or jobsite.
We source prime mill-tested raw materials accompanied by heat-number traceability, certifying chemical and mechanical properties under international standards.
Exceptional pitting resistance, hygienic cleanability, and thermal stability. Preferred for chemical processing, offshore marine filtration, sanitary food preparation, and distillation internals.
Lightweight, high strength-to-weight ratio, and non-magnetic properties. Outstanding choice for modern architectural facades, automotive acoustic shields, and aircraft ventilation components.
High mechanical toughness and cost efficiency for heavy industrial machinery shields, mining vibratory screens, conveyor guards, and agricultural silos.
High electrical and thermal conductivity combined with natural antimicrobial properties and warm golden luster for luxury architectural decoration, RF shielding, and specialized musical equipment.
For mission-critical chemical reactors, flue gas desulfurization (FGD), and chlor-alkali environments requiring Hastelloy C-276, Monel 400, Inconel 625, or Grade 2 Titanium perforation.
Post-perforation processing ensures sheet flatness and surface excellence through hydraulic roller leveling, ultrasonic degreasing, pickling, passivation, and electropolishing.

Common technical questions answered by our engineering and metallurgy department.
We produce round hole (60-degree staggered, 45-degree, and straight line), square hole, slotted and oblong patterns, rectangular holes, hexagonal perforations, embossed dimples, and custom artistic architectural designs. Our CNC turret punch press tooling can be customized to any CAD-supplied specification.
We fabricate perforated sheets in austenitic stainless steel (SS 304, 304L, 316, 316L, 321, 310S), aluminum alloys (1050, 3003, 5052-H32), carbon steel (IS 2062, ASTM A36), hot-dip galvanized iron (GI), brass (CuZn37), pure copper, and specialty nickel alloys (Hastelloy C-276, Monel 400).
Thickness ranges from 0.3 mm up to 15.0 mm. Standard panel sizes are 1000 x 2000 mm, 1220 x 2440 mm (4x8 ft), 1250 x 2500 mm, and 1500 x 3000 mm. Custom cut lengths up to 6000 mm or continuous perforated coils are manufactured to order.
For standard 60-degree staggered round holes, the formula is: Open Area (%) = (D² × 90.69) / C², where D represents the hole diameter and C represents the center-to-center pitch distance. Our engineering department verifies pressure drop and open area calculations for process filtration and ventilation applications.
