Painted aluminium sheet for facades

Coil-coated aluminium is flat aluminium sheet that has been cleaned, primed and painted on a continuous line before it is cut or formed. Painting a flat strip gives an even film thickness and consistent colour from batch to batch, which is difficult to achieve with powder coating applied to formed parts. The sheet is then folded into cassettes, reveals, flashings, parapet caps or lamellas, or seamed into roofing.

VENTFASAD 24 LLC designs ventilated facades for projects in Georgia, and aluminium sheet is one of the materials we use most. This section lists the sheet by coating system and by decor, so you can compare finishes and request the right sample.

Thicknesses and forms

For facade cassettes the sheet is typically 1.5 to 2.5 mm thick, while roofing and flashings use thinner material of around 1 mm. The sheet is supplied flat in sheets, or as coil, and parts are made to project dimensions. Because aluminium is non-combustible, it is a strong choice where fire regulations are strict.

Coating systems

PE (polyester): economical, flexible and available in a wide palette. Best for interiors and moderate exposure.
PU (polyurethane, polyamide): higher abrasion resistance and UV stability, suitable for civil and industrial facades.
PVDF (fluoropolymer): the most durable system, recommended for strong sun, marine air and long service life.
PLASTCOVER: a thicker decorative system with a printed decor under a protective film.

Beyond plain colours the range includes metallic, anodised-look, brushed, textured and wood, stone and concrete effects. The sub-sections explain each effect and where it works.

Using aluminium sheet on a Georgian facade

Aluminium suits both the humid coast at Batumi and the sunny, dry conditions in Tbilisi. In coastal locations PVDF is the safest choice. Plan for thermal movement: a 3 m aluminium cassette changes length noticeably between a winter morning and summer afternoon, so fixings, joints and returns are designed accordingly. Separate aluminium from steel fasteners to avoid galvanic corrosion, and use stainless or coated fixings. Aluminium skin itself does not burn, but the wall assembly behind it still matters. For buildings above 12 m, Chapter 14 of the Building Safety Rules (Resolution No. 41 of 2016, based on the IBC) applies, and insulation and cavity barriers are checked within the assembly.

Selecting a finish

Test the colour next to adjacent materials in daylight.
Choose directional effects, such as brushed or metallic, only when orientation can be controlled in layout.
Consider cleaning access and dirt exposure; light textured surfaces hide dust better than high gloss.
Ask for coating system, film thickness and colour match when requesting quotations.

Design with supply

The same drawings used for the facade provide the cutting and folding data for cassettes, so parts are made exactly to size. Pricing is on request.

Send us your elevations or a specification and we will prepare a calculation of aluminium sheet and cassettes.
