Different material specifications:
1220×(W)×2440(L)×2.5(Th)mm Aluminum thickness: 0.08mm
1220×(W)×2440(L)×3(Th)mm Aluminum thickness: 0.08----0.21mm
1220×(W)×2440(L)×4(Th)mm Aluminum thickness: 0.12----0.50mm
Non-standard size: according to customer requirements, both parties negotiate.
① External wall aluminum-plastic composite panel series: There are five specifications of aluminum thickness: 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm.
② Internal wall aluminum-plastic composite panel series: There are five specifications of aluminum thickness: 0.30mm, 0.21mm, 0.18mm, 0.15mm, 0.12mm.
③ Fireproof aluminum-plastic composite panel series: There are six specifications of aluminum thickness: 0.25mm, 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm.
Plate thickness can reach 3mm ~ 6mm Length: 2000, 2440, 3000, 3200, etc., in mm. Width: 1220, 1250, 1500, etc., in mm. Minimum thickness: 4 in mm.
The length and width of the curtain wall panels can also be negotiated by both parties. Marking code: common type, code name is G; flame retardant type, code name is FR; fluorocarbon resin coating decorative surface, code name is FC. Marking method: Mark according to the product name, classification, decorative surface, size, aluminum thickness and standard number sequence of the curtain wall panel.
Marking example: flame retardant curtain wall panels with specifications of 2440mm×1220mm×4mm, aluminum thickness of 0.50mm, and fluorocarbon resin coating on the surface. ×40.50GB/T17748－200×. Material Aluminum: the material used for the curtain wall panel The performance should meet the requirements of GB/T3880.2 3××× series, 5××× series or other series of aluminum alloys with better corrosion resistance and mechanical properties. Aluminum should be cleaned and chemically pretreated to remove oil, dirt and loose oxide layers naturally formed from contact with air from the surface of the aluminum, and to form a layer Chemical conversion coating to facilitate strong bonding of aluminum to coating and core.
