Specification of light steel keel
(1) Product specification series?
The main specifications of partition keel are divided into Q50, Q75 and Q 100. The main specifications of ceiling keel are divided into D38, D45, D50 and D60.
(2) Product labeling method?
The marking sequence of light steel keel is: product name, code, width and height of section shape, thickness of steel plate and standard number. For example, the "C"-shaped ceiling keel with a width of 50mm, a height of 15mm and a steel plate thickness of 1.smm is marked as: light steel keel for building? DC？ 5? 0? XIS？ XI。 ? SGBllg？ sea level
(3) Appearance quality The light steel keel should be smooth and sharp, and the incision should not have burrs and deformation that affect the use. The galvanized layer is not allowed to have defects such as peeling, swelling and falling off. For corrosion, damage, black spots, pits and other defects. When the test is carried out according to the specified method, the provisions in Table 2-8 1 shall be met. When checking the appearance quality, visual inspection shall be carried out in bright light 0.5m away from the product. The surface of light steel keel should be galvanized for rust prevention, and its double-sided galvanized amount: top grade should not be less than? 120g/m*m, the first-class product shall not be less than 100g/m*m, and the qualified product shall not be less than 80g/m*.
What is the price of light steel keel?
Light steel keel ceiling is divided into several levels. The first level is flat roof, and the price is higher in 40 yuan. The second grade is generally a little sculpted, and the price is around 50 yuan. The third-grade light steel keel ceiling is difficult, and the general price is around 60 yuan. If light steel keel is used as partition, the price in 30 yuan is generally high, and the price of light steel keel can be roughly divided into these categories.

How to choose light steel keel?
1. Ensure that the light steel keel has an advanced finishing system.
Because the finishing system can help products have good flatness and straightness, and the internal stress is small, thus ensuring stress-free deformation.
2. Excellent corrosion resistance is required.
The product is required to adopt high-quality continuous hot-dip galvanized sheet as raw material, and the zinc layer has strong adhesion, and the amount of double-sided zinc plating reaches or exceeds the national standard of excellent products.
3. This product has a high standard of section size, reaching the relevant national standards.
High standard section size, flange height higher than national standard, large moment of inertia, enhanced structural stability and convenient construction. For example, according to the national standard, the height of the U-shaped keel flange of the partition wall is greater than 35 mm, the products of most keel manufacturers are less than 35 mm, and the height of the U-shaped keel flange of the keel reaches 40 mm The physical index of the dragon keel I used before is much higher than the national standard.
4. Product manufacturers should have strong innovative research and development capabilities.
Manufacturers of light steel keel products should have a unique patented product series, and it is best to have products with special requirements such as ch keel, Z soundproof keel, unequal keel and E keel.
The above is Bian Xiao's detailed knowledge about light steel keel. I hope everyone can better understand the knowledge of light steel keel through our sharing. Light steel keel is becoming more and more important in our life, which has a great influence on our life. Widely used in factories, commercial streets, office buildings, stations, offices and other occasions. In addition, light steel keel has very good performance, light weight, good thermal insulation, environmental protection and excellent impact resistance, so light steel keel is more and more recognized by everyone in our life.
