What are the types of dragon bone machines

Types of keel machines

Light steel keel can be divided into ceiling keel and partition keel according to their purposes, and can be divided into V-shaped, C-shaped, T-shaped, L-shaped, and U-shaped keels according to their cross-sectional forms.

The marking sequence of light steel keel is: product name, code, width and height of cross-sectional shape, steel plate thickness, and standard number. The suspended ceiling keel with a cross-sectional shape of "C", a width of 50mm, a height of 15mm, and a steel plate thickness of 1.5mm is marked as: Building Light Steel Keel DC50 × 15 × 1.5 GB11981.

The appearance quality of the light steel keel should be flat, with clear edges and corners, and the cut should not have burrs or deformations that affect its use. The galvanized layer shall not have defects such as peeling, nodules, or detachment. For defects such as corrosion, damage, black spots, and pitting, they should comply with the provisions of Table 2-81 when tested according to the prescribed methods. When inspecting the appearance quality, visual inspection should be conducted under bright lighting conditions at a distance of 0.5m from the product.

The surface of light steel keel should be galvanized for rust prevention, and the double-sided galvanizing amount should not be less than 120g/m * m for high-quality products

Baked paint keel

The painted keel is made of fire-resistant galvanized sheet, which is durable and long-lasting. Adopting an economical placement structure, special connection method, and combined loading and unloading. Convenient, time-saving, and easy to construct. The surface of the keel is made of galvanized steel plate, which has been treated with baking paint.

The difference between light steel keel and painted keel is that general light steel keel does not undergo surface coating treatment, only coating (galvanizing), while painted keel surface has been painted, generally in black and white, with a few baked in other colors according to design requirements. This is mainly because painted keel is mostly used for exposed keel, and painting is done to ensure that the exposed parts do not rust or affect the appearance.

Mingjia keel

Flat series, groove series, and three-dimensional groove series. Hidden frame keel: Flat series

The painted keel has a good overall flat effect, simple lines, and a beautiful and generous appearance. The painted keel is safe, sturdy, and aesthetically pleasing, suitable for various types of mineral wool ceilings, aluminum block ceilings, calcium silicate boards, and other supporting constructions.

It has the advantages of light weight, high strength, waterproofing, fireproofing, shock resistance, sound insulation, sound absorption, etc. At the same time, it also has the advantages of short construction period and easy construction. It is a new type of ceiling decoration material widely used in shopping malls, courtyards, banks, hotels, factories, terminals, etc.

The main specifications of partition keel are Q50, Q75, and Q100.

The main specifications of the ceiling keel are D38, D45, D50, and D60.
