Slotted hole perforated metal
Featuring elongated slot-shaped perforations arranged in straight or staggered rows, slotted metal provides targeted directional flow control and high separation throughput. Designed specifically for sorting operations where standard round apertures would plug or bind.
Standard technical parameters
Slotted profiles balance structural integrity with high percentage open area for targeted fluid and solid paths.
Standard narrow to heavy-duty aperture widths for precise material sizing.
Elongated dimensions customized to flow rate and retention targets.
Carbon steel, 304/316 stainless grades, and light architectural aluminum.
Configured for linear directional flow or maximum open-area strength.
Built for high-volume filtration and control
Dewatering screens
Rapid liquid discharge while retaining solids in aggregate processing, mining, and food wash lines.
Fibrous & particulate filtration
Prevents elongated media and pulp fibers from blinding standard round or square perforations.
Drainage covers & trenches
High intake capacity engineered to direct stormwater away from commercial and industrial surfaces.
Architectural louvers
Engineered shading, ventilation facades, and acoustic damping with clean horizontal or vertical lines.
Formed in structural & corrosion-resistant alloys
We manufacture slotted perforated panels in prime certified alloys. Each sheet is leveled to minimize internal stamping stresses and ensure clean mounting flatnesses.
Carbon Steel
Economical choice for structural frames, sorting chutes, and dry processing.
Stainless Steel 304 & 316
Corrosion-resistant grades recommended for wet dewatering and aggressive chemicals.
Aluminum
Lightweight and weather-stable for HVAC grilles, facade cladding, and sunshades.

Slotted perforation standards and tooling options
Slotted sheets deliver higher open areas and directional flow control. Review standard tooling ranges, pattern arrangements, and compatible metal alloys below.
Tooling supports both rounded-end (standard obround) and square-end slotted configurations across sheet gauges from 24 ga up to 1/4 in plate.
Straight row pattern
90 deg alignmentSlots align horizontally and vertically. Ideal for continuous drainage channels, louver panels, and architectural sunscreens where clean sightlines matter.
Staggered row pattern
Side / end offsetAlternating rows increase sheet strength and eliminate straight drop lines, maximizing screening and filtration efficiency under continuous vibration.
Economical choice for dry filtration and structural framing.
General corrosion resistance for washdown and drainage systems.
High resistance to chlorides, acids, and aggressive liquid streams.
Lightweight, naturally corrosion-resistant, ideal for louvers.
Slotted apertures retain solids while letting high liquid volumes drain freely without blinding.
Continuous directional slots provide rapid runoff handling across industrial walkways.
Shields building interiors from weather while ensuring steady airflow and sun control.
Precision slot tolerances preserve sizing consistency in bulk handling systems.
