Lightgage Steel Joist Suspended ceiling according to use keel And partition keels, including U-shaped, C-shaped, T-shaped and L-shaped keels according to the section form.
(1) Product specification series The main specifications of partition keel 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, width and height of section shape steel plate Thickness and standard number. For example, the ceiling keel with section shape of "C", width of 50mm, height of 15mm and steel plate thickness of 1. smm is marked as: light steel keel for building DC 5 0 XIS XI.SGBllg sl
(3) Appearance quality The shape of light steel keel shall be flat, with clear edges and corners, and the notch shall not have burrs and deformation that affect the use. The zinc coating shall be free of defects such as peeling, bulging and falling off. Corrosion, damage, black spot, pitting and other defects shall meet the requirements of Table 2-81 when tested according to the specified method. During appearance quality inspection, visual inspection shall be carried out under the condition of bright light 0.5m away from the product. The surface of light steel keel shall be galvanized for rust prevention. The amount of double-sided galvanizing shall not be less than 120g/m * m for superior products, 100g/m * m for first-class products and 80g/m * m for qualified products. Features of V-shaped suspended keel light steel keel:
V-shaped suspended keel, also known as card keel, is our company's * * * product, and has applied for the national decoration material * * * No. auxiliary keel - this product breaks the traditional form of ceiling keel in design and manufacturing, and uses high-quality snowflake boards as raw materials, which has strong fire prevention, rust prevention, and aging mitigation properties, Each item of Bineng has passed the national inspection (convenient construction, outstanding effect, and widely used in modern decoration projects.
There is no anchor hook symmetrically and orderly on both sides of the V-shaped groove. The hook can form an inch or metric combination with the auxiliary keel. The connection between the main keel and the auxiliary keel needs to be locked with eight centimeter screws to make it more firm and durable.
Light steel keel is continuously hot plated with high quality Zinc plate The belt is a metal framework for building made of raw material and rolled by cold bending process. Used on paper Gypsum Non load bearing walls and building roof decoration with light panels such as plasterboard and decorative gypsum board. It is applicable to the modeling and decoration of various building roofs, the internal and external walls of buildings, and the basic materials of scaffolding ceiling. Features: 1. Sophisticated manufacturing equipment, advanced production technology, scientific detection means, high surface rolling precision, beautiful and straight appearance. 2. High quality cold-rolled continuous hot-dip galvanized coils are used as raw materials, with uniform material, moderate hardness, light weight, fire prevention, convenient combination, not affected by seasons, simple and fast construction, greatly shortening the construction period and improving the work efficiency. 3. The amount of double-sided galvanizing is 120g/m2, with strong corrosion and rust resistance and long service life. 4. Reasonable section structure and humanized design: the pitting design of auxiliary keel and vertical keel can effectively prevent the side slip of self tapping screw and improve the construction speed; The stiffening rib design at the side of the auxiliary keel improves the rigidity of the keel, and has stronger anti sinking ability; The design of the high and low sides of the vertical keel makes the buckle more perfect, and increases the design scheme of product application.
Shengming Decoration Company sells light steel joists for suspended ceilings and partition walls, and undertakes the works of light steel joists for suspended ceilings and light steel joists for partition walls.
