The V-type hanging keel, also known as the card keel, is an exclusive patented product of our company, and has applied for the national decorative material patent number (main dragon-ZL002 63956.4; deputy dragon-ZL003 34437.1). This product breaks the traditional form of ceiling keel in design and manufacture, and uses high-quality snowboard as raw material, which has strong fireproof, anti-rust and anti-aging properties. All functions have passed the national inspection (GB11981-2001), and the construction is convenient. The effect is outstanding and it is widely used in modern decoration engineering. The two sides of the V-shaped groove are symmetrically and orderly arranged with an anchor-like hook. The hook can form an inch or metric combination with the auxiliary keel. The main keel and the auxiliary keel are connected with an eight-cm screw to make it stronger and durable. . V-type hanging keel installation attention 1.

The joint must be reinforced with keel. The gypsum board should be installed under the condition of no stress. It should not be placed under strong pressure. It should be ensured that the bottom surface of the sub keel is in the same plane and the keel is connected. Should be staggered. The paint keel is made of cold-rolled continuous hot-dip galvanized steel strip and baking strip as raw materials, and is formed by a cold-bending process and a thin-walled profile of a reasonable "T"-shaped cross-section structure.
