我们经常见到的吊顶龙骨，特别是造型吊顶，都是用龙骨做骨架，然后贴上石膏板的。龙骨是指用轻钢制作的，用于吊顶的主要材料。
The ceiling keel system is equipped with a special hoisting system, and the light steel keel used for the ceiling includes a bearing keel, a covered keel, a hanging piece, a pendant, a hanging insert, a bearing keel connector, a covered keel connector, a lifting bar, and the primary and secondary keel is a light steel keel. The aluminum plate is a portal detachable keel system, and each panel can be easily disassembled, assembled and restored. The tubes can be disassembled independently. The boom is Φ8mm, and the surface of the boom and bolt is chemically blackened, and its anti-corrosion performance should be higher than the building standard. The ceiling keel and accessories are made of galvanized steel plate (belt) as raw material (thin-walled section steel produced by cold forming process), and the national standard 1.5mm thick galvanized steel plate (belt) "Bending Test Method for Metal Materials" (GB/T 232-2010), roll forming, forming cross-section size of 15mm×50mm×15mm. Hot-dip galvanizing on the surface of the keel "Technical Requirements and Test Methods for Hot-dip Galvanized Layer of Metal Covering Layer for Iron and Steel Parts" (CB/T13912--2002), the amount of double-sided galvanizing reaches 120 The surface is sprayed with black electrostatic powder.
