Frames
Aluminium
Aluminium is a light, corrosion-resistant metal extruded into hollow sections for shopfront frames, doors and cover trims. Shop frontages usually use a 6063 series alloy, finished with powder coating or anodising, because it carries large panes of glass on slim sightlines.
Where does it work well?
Modern retail frontages, takeaways, offices and multi-unit parades that need slim frames, big glass areas and a durable colour finish, with low upkeep and straightforward repair by replacing individual sections.
Pros
- Light but stiff enough for large panes
- Slim sightlines
- Does not rust
- Sections can be replaced one at a time
Cons
- Conducts heat unless thermally broken
- Dents under hard impact
- Can look out of place on a traditional frontage
How long does it last?
Typically decades with regular washing, though coatings and seals need attention sooner.
What should you check when buying?
Ask for the section depth, wall thickness and finish specification, not just a colour. Check that the frame suits the weight of the glass, and that the door section takes the lock and closer you need. Confirm the coating suits your location.
Common questions
Should I choose aluminium or timber for my shopfront?
Aluminium needs less upkeep and carries larger panes, while timber suits traditional streets and listed buildings. In conservation areas the council may prefer timber, so the planning setting often decides the choice before cost does.
Does aluminium corrode?
Aluminium does not rust, but it can corrode, especially where salt or pollution sits on the surface or steel fixings touch it directly. A sound coating, isolated fixings and regular washing keep this in check.
