Perforated Metal Signage for Facades, Screens and Entrances

• Building facades and cladding with integrated branding
• Parking structures and ventilated screens
• Plant and service screens that must breathe
• Balustrades, fences and boundary screens carrying a logo
• Reception and interior partitions
• Shopfront screens and awnings that need shade with identity

Perforation works best on large surfaces viewed from a distance, where the pattern merges into an image.

• Variable hole sizes: varying hole diameter creates tone, so a logo or image appears from a distance.
• Uniform patterns: a consistent perforation with one area solid to show a logo.
• Pattern shapes: round, square or slotted holes.
• Panel formats: flat sheets, folded trays, or curved panels.
• Layered screens: two perforated layers for depth, or a coloured layer behind.
• Combining with cut-outs: perforation plus cut lettering; see laser-cut metal signs

• Aluminium sheet is light and paintable, common for facades.
• Stainless steel: durable and clean.
• Mild steel: strong and economical when well coated.
• Corten: rust-toned weathering steel; see corten steel signs.
• Coatings: powder-coat or paint in brand colours, applied after perforation.

Perforated panels are excellent with light, as it can pass through the holes.

• Backlighting with LEDs behind the panel so the pattern glows at night
• Edge or uplighting that skims the surface
• Colour-changing options, subject to technical assessment and confirmed availability
• Daylight shadow patterns on interior floors and walls

For a uniform, lit surface, a lightbox is more even; perforated panels give a textured, dotted glow. Cable routing and access are planned at survey.

• Laser-cut panels use bold cut shapes; perforation builds an image from many small holes.
• Etched signs keep the surface whole and suit close reading.
• Architectural facade signage integrates signage into a facade; perforated metal is one common material for it.
• Lightboxes give an even glow; perforated panels let air and light through.

• Open area: the percentage of holes affects strength, airflow and how visible the image is. We balance these.
• Wind loading: perforated panels let wind through, but framing must still be designed for loads, confirmed with the relevant professional where required.
• Viewing distance: as a rough guide, many designers allow around 25 mm of letter height per 10 m of viewing distance; image detail needs more distance to merge.
• Background: what sits behind the panel affects how the pattern reads.
• Flatness: large panels need adequate thickness and bracing to stay flat.
• Approvals: structural, electrical and municipal approvals are checked at survey and design stage and may involve landlord, body corporate or municipality.

• Sheet size, thickness and material
• Pattern complexity and hole count
• Folding, curving and framing
• Coating colour and finish
• Backlighting and cabling
• Installation height and access

Hose or wipe down regularly so dust does not clog holes. Check coating for chips and treat promptly. Inspect fixings and framing after storms. If lit, have drivers and LEDs checked; see LED signage repairs and cleaning and maintenance.

Surveys and installation are arranged by appointment from our Rivonia base. Perforated panels are specified for facades, parking and screening in Sandton, Johannesburg, Pretoria, Midrand, Centurion and industrial areas such as Isando.
