Perforated Metal Questions: Materials, Hole Sizes and Custom Sheets

We make perforated metal sheets from stainless steel, galvanized steel, copper, aluminum, nickel, and alloy steel. The product range also includes iron plate and stainless steel wire options. The right material depends on the working environment, required finish, thickness, and intended use.

For a filtration, equipment-cover, or architectural order, send us the material grade or application conditions together with the required thickness and hole size. We can then review the sheet construction for the intended job.

We produce round, square, rectangular, diamond, hexagonal, triangular, cross, plum, star-shaped, and irregular holes. Punch diameters range from 0.3 mm to 100 mm in the listed range.

Cold-rolled steel sheets are listed at 0.2 mm to 1 mm thick and 1 m to 20 m long, with 0.8 mm to 10 mm holes. Plate products are listed at 0.3 mm to 10 mm thick, with a maximum size of 1.5 m by 3 m and hole diameters from 0.8 mm to 100 mm. The listed precision example pairs a 0.5 mm plate thickness with a 0.5 mm hole.

A small-hole order should include a clear drawing or sample. Hole size, sheet thickness, pitch, and edge margins all affect how the finished panel fits the application.

Yes. We produce sheets according to customer requests with CNC equipment and model-based production. A custom inquiry should include the material, thickness, overall length and width, hole shape, hole diameter, pitch or arrangement, quantity, and surface treatment.

A drawing is useful for irregular patterns, edge margins, or holes that must align with another component. We can review requested dimensions for machinery protection covers, filtration equipment, building panels, shelves, and decorative screens.

We supply spray painting, polishing, oxidation treatment, and galvanizing. The finish should be selected together with the material and working environment.

Polishing supports a smooth appearance. Spray, oxidation, and galvanized treatments provide different finish options for industrial, architectural, and general metalwork applications. Tell us whether the sheets will be used indoors, outdoors, around machinery, or in filtration or food-machinery equipment. Include the desired color or finish when appearance matters.

Applications include sound-absorbing panels, interior and exterior wall decoration, building ceilings, stair and balcony panels, machinery protection covers, speaker covers, shelf netting, exhibition platforms, kitchen utensils, chemical machinery, pharmaceutical equipment, food machinery, handicrafts, and filtration equipment.

A machinery builder can specify the hole pattern and sheet size for a protective cover, then check the finished panel against the equipment opening before installation. An architectural buyer can select a regular pattern and surface treatment for a ceiling, balcony, or display platform, then confirm panel dimensions and edge details before ordering.

Send a drawing or pattern image, material, thickness, hole shape and diameter, arrangement or pitch, sheet dimensions, quantity, surface treatment, and application. If the order uses cold-rolled steel, include the required length because the listed range is 1 m to 20 m. For plate products, confirm the required size against the listed maximum of 1.5 m by 3 m.

Also tell us whether the sheets are for filtration, sound absorption, decoration, equipment protection, shelving, or another use. Include the opening dimensions or mating-part drawing when the panel must fit an existing assembly. Send these details with the required quantity so we can review the custom order accurately.
