Classification: According to the burning performance of the curtain wall board, it is divided into ordinary type and flame retardant type.
Specifications and dimensions: Common specifications for curtain wall panels are as follows:
Length: 2000, 2440, 3000, 3200, etc., the unit is mm.
Width: 1220, 1250, 1500, etc., the unit is mm.
Minimum thickness: 4, in mm.
The length and width of the curtain wall panels can also be agreed between the supplier and the buyer.
Mark code: common type, code G; flame retardant type, code FR; fluorocarbon resin coated decorative surface, codenamed FC.
Marking method: Mark the product name, classification, decorative surface, specification size, aluminum thickness and standard number of the curtain wall panel.
Marking example: Flame-retardant curtain wall panel with a specification of 2440mm×1220mm×4mm, aluminum thickness of 0.50mm and fluorocarbon resin coating on the surface, marked as: Example – aluminum-plastic composite panel for building curtain wall FRFC2440×1220 ×40.50GB/T17748-200×.
Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
