Classification of light steel keel

Classification of light steel keel

Light steel keel according to the use of the ceiling keel and partition keel, according to the form of section has U type, C type, T type, L type keel.

1.product specifications series partition keel main specifications are divided into Q50, Q75 and Q100.The main specifications of ceiling keel are D38, D45, D50 and D60.

2.Product marking method The marking sequence of light steel keel is: product name, code name, width and height of section shape, thickness of steel plate and standard number.If the section shape is “C” type, the width is 50mm, the height is 15mm, the steel plate thickness is 1.The ceiling keel of SMM is marked as: light steel construction keel DC 50 XIS XI.SGBllg sl

3.the appearance of the quality of light steel keel shape should be smooth, clear edges and corners,the incision is not allowed to affect the use of burr and deformation.Galvanized layer is not allowed to have peeling, tumor, fall off and other defects.For corrosion, damage, black spot, pitting and other defects, the specified method should be tested in accordance with the provisions of table 2-81.When inspecting the appearance quality, visual inspection should be carried out under the condition of bright light 0.5m away from the product.The surface of light steel keel should be galvanized and rust proof, and the amount of double-sided galvanized: superior product is not less than 120g/m*m, first-class product is not less than 100g/m*m, qualified product is not less than 80g/m*m.V type hanging keel light steel keel characteristics:This product in the design and manufacturing are broken the form of traditional ceiling keel, and the use of high quality snowflake board as raw materials, fire prevention, rust prevention, slow aging performance is strong, all will be able to pass the national detection (construction is convenient, the effect is outstanding, widely used in modern decoration projects.

There is no anchor hook symmetrically and orderly on the two side walls of the V-shaped groove. The hook can be combined with the auxiliary keel in English or metric system. The connection between the main keel and the auxiliary keel needs to be locked with 8 cm screws to make it more firm and durable.

Light steel keel is made of high quality continuous hot galvanized sheet as raw material, which is rolled by cold bending process.It is used for decoration of non-bearing wall and roof of buildings with light board such as plasterboard and decorative plasterboard as decorative surface.It is suitable for the modeling and decoration of the roof of various buildings, the internal and external walls of buildings and the basic materials of the scaffold ceiling.

Features:

1. Excellent manufacturing equipment, advanced production technology, scientific detection means, high rolling accuracy of the surface of the product, beautiful appearance, straight.

2. The use of high quality cold rolled continuous hot galvanized coil as raw material, uniform material, moderate hardness, light weight, fire prevention, convenient combination, not affected by the season, the construction is simple and quick, greatly shorten the construction period, improve the work efficiency.

3.the amount of double-sided galvanized is 120 grams/square meter, corrosion resistance and rust resistance is strong, long service life.

4.the section structure is reasonable, humanized design: auxiliary keel and vertical keel of the pitting point design effectively prevent the self-attack nail side slip, improve the construction speed;The reinforcing rib design at the side of the auxiliary keel improves the rigidity of the keel and makes it more resistant to subsidence.The high and low edge design of vertical keel makes the fastening more intact and increases the design scheme of product application.
