Color steel plate storage

 

Color steel plate

Color steel plate, despite the double protection of galvanized layer and organic coating on the surface of the steel plate, if it is in a humid state for a long time, the water accumulated on the surface (including water produced by condensation in the air) will gradually infiltrate through the organic coating, thus causing corrosion of the zinc layer under the film of the organic coating, so attention must be paid to it when it is stored:

(1) Not to be wet by water, stored indoors, avoiding open stacking.

(2) The room should be dry and ventilated, without corrosive gases, and must avoid being placed in a place that is prone to condensation as well as the big temperature difference between cold and warm. Forced to temporarily store outdoors, underneath must have a square sleeper for cushion wood, and pay attention to good ventilation, choose flat ground, cushion wood above should also be horizontal, to make the steel plate stacked at the same height, to prevent the occurrence of warping, the product above the cover with a rainproof cloth, protect the product is not directly affected by the sunshine and rain.

(3) If the color steel plate is subjected to rain or has condensation, it should be unpacked immediately and dried quickly to remove moisture and used as early as possible.

(4) The steel coil should be stored in the same condition as when it left the factory as far as possible, and should not be piled up, so as not to damage the coating.

(5) Color-coated steel plates should not be placed in sand, or dusty places. If sand and dust accumulate on the steel plate, it may damage the coating film of the coated steel plate. And sand, dust accumulation, will make the coating surface not easy to keep dry and become the root cause of corrosion.

(6) Long-term storage should be avoided, the use of first-in-first-out as a principle, to avoid long-term retention of the pollution caused by unused, bruises, as well as new and old products mixed with the appearance of small color differences, especially in the coastal and industrial atmosphere of the environment, it should be shortened storage period.

(7) To exclude moisture that for some reason is trapped on the surface of the steel plate in the package, the steel plate may be placed at an incline in the warehouse, with a suitable angle of inclination of 3.5 degrees.

Several cutting methods of steel structure space frame

图片
  Steel st ructure space frame s are now widely used, such as galvanized steel warehouse , glass dome building , airport hangar ,steel structure warehouses, hall roofs, gymnasiums, etc. The builder will cut, produce, and process according to the customer's requirements. There are many ways to cut steel structure space frame s, which will help you to have more choices of cutting. Then, the space frame   manufacturers below will give us a detailed description of several common cutting methods. The cutting methods of the steel structure space frame   are as follows: 1. Flame cutting by CNC machine tools: that is to say, use oxygen cylinders to oxidize and melt steel at a high temperature continuously. At present, natural gas is generally available, which is relatively reliable. 2. Waterjet cutting machine: Generally, high-pressure flowing water is used for cutting, and the accuracy is very high. It is often cut in some very thin, medium-thick steel that requires precision m...

What are the advantages of steel over traditional concrete?

图片
  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more f...

Space frame cost control

图片
  With the continuous improvement of socialist productivity, various industries are developing in the direction of rapid development, so is the steel space frame engineering industry. Due to the Therefore, we should attach great importance to the  space frame cost  management, because the project involves many aspects and fields, and only through reasonable project space frame cost management, can we ensure the quality of the last step of the project. Therefore, we should fully realize that dynamic management and control of project cost is a very important work content and link. In order to improve the quality level of steel grid engineering, dynamic management and control of project cost should be further strengthened. Optimizing the investment process is the most critical link in the steel space frame. the same time, it is also a very important aspect in the process of space frame construction cost management. Therefore, active and effective measures should be take...
