How can I Judge the Quality of Color Steel Plat

-

 No.1 Method, observe the thickness of the substrate and the thickness of the laminate. Color steel plate is composed of the substrate and the colored laminating film or coating. We first have to consider the thickness of the substrate and lamination and coating, the better color steel substrate is 0.02-0.05mm, and the thickness of the lamination or coating is often only 0.15mm or less. Because from the influence of color steel plate use time point of view, the thickness of the substrate is very important. But some manufacturers make changes on the substrate and color steel plate coating or coating, they reduce the thickness of the substrate, but increase the thickness of the peritoneal membrane to reduce the production cost of the color steel plate, which greatly reduces the service life of the color steel plate.

No.2 Method, observe the leaky edge of color steel plate. Observe the leakage edge of the color steel plate is also a relatively simple method. Get a piece of colored steel plate, we can first observe whether the exposed steel such as section of colored steel plate is crystallized fine, whether it is gray, dark and impurity. If the cut surface is crystalline fine type is superior quality.

No.3 Method, listen to the sound. The so-called method of listening to the sound is also relatively simple, that is, use your finger or hit the color steel plate with something hard, if the material of the color steel plate is poor, then the sound sent out is muffled, metal sound is not obvious; The material is better color steel plate metal sound is relatively loud, crisp. This method is very easy to use for people who know a little about the color steel plate, intuitive and easy to operate, and does not require any auxiliary tools.

In what areas are steel structures usually used

-

Steel structure manufacturers can process a wide variety of products, including the following categories: 1. Single and multi-story industrial and residential buildings. 2. Office buildings, primary and secondary schools, hospitals. 3. Luxury villas, tourism buildings. 4. Modern commercial buildings for various markets. 5. Mobile buildings (demountable buildings, emergency projects). The main building materials in membrane structure engineering are steel and membrane materials. For steel structures, the main processing flow includes: material feeding → cutting → inspection → assembly welding → rust removal → numbering packaging → factory. The precautions are: 1. Materials must have a material certificate. 2. According to the cutting length and rod specifications calculated by the designer, the rods are classified and stacked for easy construction in the next step. 3. According to the penetration size of the steel pipe, considering the influence of wall thickness and groove, the automa

Three Methods of Space Frame Installation

  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyramid structure and the triangular pyramid structure. Each vertebral structure

Coal Storage Facilities: The Future with Steel Structures and Space Frames

-
Image
  Coal storage facilities, including coal storage sheds, dry coal yards, and coal storage warehouses, have always been crucial in the coal industry. The application of steel structures and space frame technology is redefining the future of these coal storage facilities. These technologies not only enhance coal storage efficiency but also improve facility performance and sustainability. Challenges of Coal Storage Facilities: Coal storage facilities need to store large quantities of coal while ensuring it remains dry and of high quality. Traditional coal storage facilities often face issues such as coal dust emissions, inadequate humidity control, and maintenance difficulties. The application of steel structures and space frame technology offers new solutions to address these challenges. Advantages of Steel Structures: Steel structures play a pivotal role in coal storage facilities. Their high strength and flexibility make them an ideal material for supporting large-scale coal storage
