A precision-fitting corner piece that joins per-metre aluminium frame profiles into a right-angled, closed frame in moments. It is ideal for self-built or under-repair scrolling signs and LED boards where a stable, durable corner joint is needed. The compact fitting is easy to secure with a tool and does not weaken the structural rigidity of the profile. A small component without which no self-built frame would be complete, available immediately from stock when you need it in a service situation.
Corner piece for aluminium frame
The corner piece is the indispensable partner to the per-metre aluminium frame profile: this fitting joins two sections of profile at an exact right angle, forming the frame of a scrolling sign or LED board into a closed structure. The part is shaped to sit tightly inside the cavity of the profile, which keeps the joint not only neat but structurally strong. Whether you are building a completely new frame or repairing an existing corner, this element ensures quick and dependable assembly. Because of its compact size it can also be held in stock as a spare part, so that it is immediately to hand in a service situation.

Why the right corner piece matters when building a frame
The frame of a scrolling sign or LED board is only as strong as its corner joints: if the corner piece is weak or fits imprecisely, the frame can shift and work loose over time, which can also damage the LED modules and electronics built into it. A well-designed corner piece matches the internal geometry of the profile exactly, so the joint stays tight and leaves no gap through which moisture or dust could enter the structure. That matters especially on outdoor scrolling signs, where temperature swings and the weather test the joints continuously. Using a corner piece also speeds up assembly considerably, since it requires no welding or complex machining: fitted into the profile and secured with a screw or a clip system, a stable corner is ready in moments. And in repair situations it is distinctly useful to have a few spare corner pieces in the store, because replacing a worn or damaged part can then be done in minutes.
Build and compatibility
The corner piece is made from the same corrosion-resistant aluminium as the frame profile, so the finished frame keeps a uniform appearance and the same service life. The shape of the fitting is designed precisely for the internal cavity of the profile, so it gives a tight, play-free fit that can be made permanent with a screw or a self-tapping fixing. The compact design does not weaken the cross-section of the profile, so the finished frame stays just as load-bearing as if it were a one-piece structure. The corner piece is compatible with every standard size of the per-metre aluminium frame profile, so it can be used without difficulty both when building a new frame and when repairing an existing sign.
Why it is worth keeping a few in stock
The corner of an outdoor scrolling sign or LED board is one of the most common weak points, because this is where two profile ends meet and where the greatest mechanical load falls from wind or thermal expansion. If you are a service company or an operator who regularly deals with such signs, it is worth procuring a few corner pieces in advance, since an on-site repair can be sorted out far more quickly when there is no separate order to wait for. Because of the small size and low unit price this is a component worth keeping in reserve, much like power supplies, since its absence can needlessly drag out a repair that would otherwise take minutes.
Typical applications
Corner piece for aluminium frame — frequently asked questions
Does the corner piece fit any aluminium frame profile?
The corner piece is designed for the standard sizes of the per-metre aluminium frame profile, and fits those without play.
Is the corner piece strong enough for an outdoor, loaded frame?
Yes — because of the tight fit and the hard-wearing aluminium material, the finished corner is just as load-bearing as a welded joint.
Can it be used to repair an existing, damaged frame?
Yes, it is distinctly practical for repairs too, since replacing a worn or damaged corner can be sorted out quickly with this element.
How long does it take to replace a corner with this element?
Because of the quick-connect or screwed fixing, replacing a corner can typically be done in minutes, even without special expertise.
How long does an outdoor corner joint exposed to the weather last?
The corrosion-resistant aluminium keeps its strength and appearance for years under continuous UV and moisture load.
Can I order a larger quantity to hold in stock?
Yes — we recommend that service companies and operators procure a few in advance, so that an on-site repair is not held up by a missing part.
