Dimensions: 150x120 - 180x120 - 200x120 - 240x120 - 270x120 - 300x120

It has a surface suitable for writing with a pen. The trio of enameled steel + chipboard + galvanized sheet is pressed, adhered and framed with a component polyurethane adhesive. It has magnetic properties. The steel enamel writing board can be used with magnetic lesson tools. A hanging bracket can be attached to the upper frame and products such as map posters can be used with the blackboard.

Writing surface: Made of a special alloy of steel and enamel (ceramic coating) at 800 C. It has a very high hardness, does not scratch, does not require paint, is easy to write and erase, does not scratch, does not require paint. It can be wiped with a wet cloth. Enamelled steel boards are supported with galvanized sheet metal from the back, and 8 mm chipboard of E1 norm is used as filling material.

Frame: Made of anodized aluminum profile with a thickness of 12-14 microns. Specific gravity is 2.71 gr/m3, expansion coefficient is 23*10 (200-100 C), elasticity modulus is 6900 kg/mm2, tensile strength is 15.5 (at 24 C kg/mm2). Hardness is 60-65 brine (HB) kg/mm2. .

Corners: Plastic angle brackets are used at the corner joints of the blackboard. These corner pieces are obtained from a mixture of polypropylene + 2% Masterbach and are produced with injection molds. Plastic material is resistant to fading. (ASTM D2565)

Rear support panels: Behind the writing surface is a sanded formaldehyde class I and class II flat chipboard. In addition, the rearmost layer contains a cold-rolled and galvanized steel plate with a hot zinc coating.

Glue: A polyurethane-based, two-component, liquid adhesive material is used between the back layers of the blackboard. The adhesive used has high adhesion to the applied surface and is resistant to wetting and many chemicals.

Mounting Unit: Galvanized steel mounting apparatus is used to allow the whiteboards to be hung on the wall practically and to make them look aesthetically pleasing.
