Aluminium Profile Doors

An aluminium profile door is a door built from extruded aluminium sections rather than timber, steel or uPVC. In a proper system, those sections are designed as a matched family: the frame, the shutter, the beads and the gaskets all made to fit each other, with grooves, drainage channels and screw ports already formed into the section.

A system profile is drawn as part of a set. Its gasket grooves, screw ports, drainage paths and interlocks line up with the beads, shutters and hardware made to go with it. An ordinary section is just aluminium in a shape. It can be assembled into a door, but the sealing, drainage and hardware fixing all become improvisation.

Casement, sliding, tilt and turn, slide and fold, lift and slide, slim openable and automatic door leaves are all built from profile systems. The choice depends on the opening width, whether there is swing space and how much of the opening needs to clear.

Wall thickness is the amount of aluminium in the section. Too little and the frame flexes under the weight of its glass, so the shutter stops meeting its gasket evenly. It is also the easiest thing for a supplier to reduce quietly, because nothing on a finished door reveals it.

A thermal break profile has an insulating barrier running through the section, separating the inner face from the outer one. It slows heat passing through the frame itself, which matters on air conditioned rooms and heavily glazed elevations where the frame would otherwise conduct heat straight through.

In a system, yes. Handles, hinges, friction stays, rollers and multi-point locking are specified to suit the profile family, so they fix into the ports the section already carries rather than being screwed into whatever surface is available.

Yes. Sections are cut and assembled to the measured opening rather than bought as finished stock units, so an existing opening does not have to be altered to receive the door.

Powder coating in a wide colour range, anodising in natural and tinted shades, and matte, glossy and wood-grain effects. The finish is applied to the section before fabrication, which is why coating consistency along the length matters.

Ask for the wall thickness in writing, sight along a length for straightness and twist, check the coating is even across the whole section, and confirm that the gaskets, beads and hardware belong to the same system. A rate well below the market usually reflects one of those four.

Yes. Aluminium does not swell in the monsoon, warp in summer heat or carry termite risk, and powder coated surfaces resist fading. What matters most is that the profile carries proper gasket grooves and working drainage, since those are what keep dust and driven rain outside.
