Type of surface material used in metal curtain wall

The surface materials used in the metal curtain wall mainly include the following: aluminum composite board, single-layer aluminum board, aluminum honeycomb board, fire board, titanium-zinc-plastic aluminum composite board, sandwich thermal insulation aluminum plate, stainless steel plate, color coated steel plate, enamel steel plate, etc. .

Aluminum composite board

It is made up of 2-5mm thick polyethylene or rigid polyethylene foam board with 0.5mm thick aluminum plate inside and outside. The surface is coated with fluorocarbon resin coating to form a tough and stable film. Adhesion and durability are very strong, rich in color, and the back of the board is coated with polyester paint to prevent possible corrosion. Aluminum composite panels are commonly used panel materials in the early appearance of metal curtain walls.

Single layer aluminum plate

The aluminum alloy plate of 2.5mm or 3mm thickness is used, and the surface of the single-layer aluminum plate for the outer curtain wall is consistent with the material of the front surface of the aluminum composite plate, and the film layer has the same toughness, stability, adhesion and durability. Single-layer aluminum plate is another common panel material for metal curtain wall after aluminum composite board, and it is applied more and more.

Honeycomb aluminum plate

It is a composite material with two honeycomb plates and a honeycomb core material bonded together. According to the function of the curtain wall and the durability of the curtain wall, the thickness can be selected separately.

Honeycomb aluminum plate 10mm, 12mm, 15mm, 20mm and 25mm honeycomb aluminum plate, 10mm thick honeycomb aluminum plate should be made of 1mm front aluminum plate and 0.5-0.8mm thick back aluminum alloy plate and aluminum honeycomb, and the thickness is above 10mm Honeycomb aluminum plate, the thickness of the aluminum alloy plate on the front and back should be 1mm, the honeycomb aluminum plate for the curtain wall should be aluminum honeycomb, the shape of the honeycomb has a regular hexagon, a flat hexagon, a rectangle, a square, a cross, a flat square, etc. Honeycomb core material should be specially treated, otherwise its strength is low and its life is short. If chemical oxygen is applied to aluminum foil, its strength and corrosion resistance will increase. The honeycomb core material has glass fiber reinforced plastic honeycomb and paper honeycomb in addition to aluminum foil, but it is not used in practice. Since the cost of the honeycomb aluminum plate is high, the amount is not large.

Fireproof board

The metal plate (aluminum plate, stainless steel plate, color steel plate, titanium zinc plate, titanium plate, copper plate, etc.) is used as a panel, and the halogen-free flame-retardant inorganic material-filled core material is a core layer.

A fireproof sandwich sandwich panel made of hot pressed composite panels. According to GB8624-2006, it is divided into two combustion performance grades A2 and B.
