WALLROC Fireproof Panel

In order to obtain highest possible strength and stiffness, Wallroc panel is composed of two types of materials : a non - combustible structural core [rockwool] bonded on both sides with coated steel sheets, thus creating an interactive composite structure that absorbs the loads acting upon it.

WALLROC is evenly strong at every cross sectional area due to small arrangement and high adhesion of structure of insulator layer. Inside the Wallroc sandwich panel is a layer of stone wools which are cut into lamellas and rotated so as to make the very fine mineral fibers align and direct at 90 degree to the steel surface to attain maximum efficiency of sandwich panel.

1. PPGI [Pre-Painted Galvanized Iron] steel sheet with two layers zinc-coated 275 g/m2 for inner layer and two layers of environmentally-resistant acrylic sealer.
2. Non-combustible insulating core provides strength to all cross sectional core of the panel.
3. Specially developed adhesive is evenly applied throughout and rigidly covered the whole surface area of the panel.
4. Multiple prime layers with high efficient adhesion between zinc-coated steel sheet and structural stone wool core.
5.  Z-Lock, the latest self-locking technology in sandwich panel manufacturing ensures the durability of connecting points on all panels.
