Architectural aluminium pressings
IQ Glass designs, manufactures and installs bespoke aluminium pressings and flashings as part of our architectural and structural glazing projects. These finishing elements create a defined surround to the glazing, with dimensions and profiles tailored to the building.
Our dedicated Aluminium Pressings and Flashings Division works alongside the glazing team to deliver a coordinated installation. From narrow trims to substantial surrounds, the pressings can form a distinctive architectural feature while providing a neat finish to the glazing perimeter.

Architectural finishes and colours
Aluminium pressings and flashings can be powder coated in a specified RAL colour or anodised to suit the architectural design. Finishes can be coordinated with the glazing frames, cladding and fascias to create a consistent appearance and a durable, low-maintenance external finish.
Alternative architectural metals, including stainless steel, Corten steel and architectural bronze, offer further design options. These finishes can complement other glazing elements, including steel framed doors.
IQ Glass can also create bespoke backpainted glass pressings, providing another option for projects requiring a different surface finish.

Concealing construction junctions
Bespoke aluminium pressings can conceal construction elements such as steel beams, floor edges and junctions between materials. By designing these details alongside the glazing, exposed interfaces can be finished neatly without interrupting the overall architectural design.
At Posterns Court, aluminium pressings complete the perimeter of the glazed extension. This close-up shows the relationship between the metal finishing details, sliding door frames and structural glass above.
Detailing around glazed roofs
Aluminium pressings provide a neat finish around structural glass roofs and can contribute to weather protection at material junctions when appropriately detailed.
At Posterns Court, the pressings were colour matched to the sliding door frames, creating a consistent finish around the glazed extension.
Flashings above glazed roofs are to be carried out by others, typically using lead flashings. This work should be coordinated with the glazing installation so that responsibilities at the junctions are clearly defined.
A coordinated glazing design
Designing pressings and flashings alongside the glazing allows colours, finishes and construction interfaces to be considered together. This helps create a consistent appearance across individual windows, doors and larger glazed elevations.
At Orchard House, bespoke pressings and flashings conceal exposed fixings, helping the different glazed elements form a coordinated architectural design around the courtyard.
Specification
Material
Our pressings and flashings are available in a wide range of architectural metals, but are most commonly created using milled aluminium that can be powder coated any RAL colour.
The aluminium pressings have a standard thickness of 2mm but are also available in 3 and 4mm thicknesses. These thicker sheets of aluminium are more suitable for thin strips of metal for stability.
Other material finishes that are available are:
Stainless Steel
CortenTM Steel
The edges of your pressings can be exposed or hidden as required. The edges can then be laser cut for a smooth exposed edge if required.
Maximum Sizes
Our aluminium pressings have a maximum length of 3000mm in single panel. Longer lengths of aluminium pressings can be created by welding multiple pressings together, polishing the weld and powder coating the finished surface for a seamless metal coating.
Aluminium pressings will be folded to fit into your structure and we can use a number of fold types and techniques to suit your project requirements,
The angle of a fold of aluminium can be between 0 and 180 degrees. Punches, holes or patterns are able to be cut into a flat piece of aluminium using a CNC machine under factory conditions. Any cut outs or holes required in your aluminium pressings should be communicated before manufacture.
