Snap-lock sheet · Concealed fixing

EXCLUSIVESnap-lock façade and roof sheet

It looks like a classic standing-seam sheet, but it is a considerably improved version of it — it goes up without a single visible screw, and longitudinal stiffeners give it rigidity and a look of its own.

Appearance

An appearance that locks itself together

A clean line with not one screw on the visible surface — the same profile covers both façade and roof, so the building reads as one whole.

01 — ABOUT THE PRODUCT

The EXCLUSIVE snap-lock façade sheet from Alternativa d.o.o. quickly earned an excellent reputation across Europe, and thanks to its outstanding qualities and appearance it has become a standard on our market too.

In looks it most resembles a classic standing-seam sheet, but it is a considerably improved version of that traditional answer. This modern, innovative profile allows a whole façade to be installed without a single visible screw, which is often what developers want when they are after a flawless finish.

The profile is further refined with elegant stiffeners along its length, which give it a distinctive and striking visual identity. The EXCLUSIVE snap-lock sheet is exceptionally versatile and can be used on different kinds of façade supporting frame.

Besides standard galvanised and coated steel sheet, this profile can also be made from special materials such as coated aluminium sheet, copper or titanium zinc, which widens the range of uses further.

A metal roof does not hide the storm — it turns the downpour into the finest music nature makes.

02 — WHY THIS PROFILE

Why choose the EXCLUSIVE snap-lock sheet?

Installation can be single-layer, straight onto a flat substrate, or in combination with a steel supporting frame based on the ELEGANT trapezoidal profiled sheet.

01
A ventilated façade

Fitted onto a supporting frame, it forms a natural ventilation channel behind the sheet.

02
High durability

Because the screws are completely hidden beneath the surface of the sheet, they are not exposed to rain, snow and UV.

03
Longitudinal stiffeners

This profile carries elegant lines of stiffening along its length, which add rigidity to the sheet and prevent oil canning.

04
Concealed fixing

The screws go into a perforated edge that is then covered by the next sheet of the panel.
