RO-070 Round Staggered Perforated Galvanized Steel Sheet
For machine guards, HVAC intake screens, filtration panels, and balanced ventilation work, RO-070 uses Galvanized Steel (GV), Pre-Galvanized (PG), Mill Finish and 60° Staggered Centers, 3/16" Round, 1/4" centers, 1/16" bar width to define a tighter purchase specification than a plain catalogue sheet.
Its 51% open area balances airflow and visibility while leaving enough web for many guarding layouts; engineering review should also reference 51% open area, 18.47 holes per square inch, 18 Gauge (.0516" Thick) max thickness, 1.08 Lbs./Square Foot sheet weight.
The zinc-coated substrate fits outdoor guards and intake screens; quote notes should confirm whether cut edges need secondary protection.
Use it in Sheet with Sheared Through Both Ends and 48" x 120" (Cut Sizes Available); quotation checks should confirm cut edges, flatness, and finish protection before production release.
Technical Specifications
Surface Treatments & Color Samples
Review coating colors and metal finish samples for PVDF, powder coating, anodizing, and natural metal finishes before sampling or production.
Mill Finish
PVDF Fluorocarbon
Architectural exterior coating for long-term weatherability, UV exposure, and stable color performance.
Electrostatic Powder Coating
Wide RAL color range with matte, fine-texture, and branded color options for custom production runs.
Anodizing
Metallic aluminum finish options that retain the substrate character in clear, champagne, bronze, or black tones.
Natural Metal & Galvanized
Mill, brushed, galvanized, and clear-seal finishes keep the metal character visible while adding project-specific corrosion protection.
Select the finish around exposure, target color, and inspection sample. We can match RAL colors, metallic tones, or natural metal textures before production.
Product Data
Engineered for
Performance
Our perforated metal products are produced by punching a series of patterns in a solid material. These patterns can be round, square, rectangular, or decorative depending on your specific requirements.
We offer a wide range of styles to suit any industrial or architectural need, from lightweight decorative elements to load-bearing structural components.
Aluminum, Stainless Steel, Carbon Steel, Galvanized, Brass, and Copper.
Advanced CNC punching ensures sub-millimeter accuracy across all patterns.
