The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.

Iron wire rust is a headache, not only the product performance decline, affect the use effect and life, and rust to human body and the environment also has a certain harm. Galvanized iron wire compared with ordinary iron wire more than a galvanized process, galvanized iron wire can rust?

In general, the cost of hot dipping zinc is lower than that of other maintenance coatings. The reason is very simple. Other maintenance coatings, such as sand painting, are labor-intensive processes, whereas hot dipping zinc processes are highly mechanized and tightly controlled in-plant construction. Hot dip zinc coating can be visually and briefly tested for non-destructive coating thickness.

The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire. Control drawing process parameters: drawing speed 10 ~ 12m/s; Winding tension 8 ~ 10N; Measuring length 30km; The mass fraction of lubricant is 3.5 ~ 4.5%; pH value of lubricant 7 ~ 8; Lubricant temperature 30 ~ 40℃.

Fence use: The use of the fence is generally one meter two to two meters a height of the impregnated welding mesh, mesh mostly 6cm, wire diameter from 2mm to 3mm.

A pet carrier can be used as an indoor and outdoor pet house. The dog cage is equipped with a fixed food basin and drinking water, and the foot plate pet cage rubber pad has bayonets on four sides to be collated. According to the cage size can be splicing, cutting, disassembly is convenient, easy to clean, can solve the puppy in the ordinary cage foot clamping problem, prevent the puppy in the development of adverse reactions. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet that does not hold its feet or pinch its feet.

3, with oil cloth (oil used cloth), carefully from inside to outside, including each cage wire repeatedly grinding many times. The front of the bird cage, the door flowers, where vision is often in place, are repeatedly rubbed in order to improve the surface finish, equivalent to “grinding”. Note: door flowers, arhat lines and other structures are delicate and fragile, do not break. This process, which requires time and patience, care, is also a process of observing and appreciating the cage. Use new cloth again, according to the above process, wipe again and again. This process is equivalent to polishing. For important parts, you can use a little force, the speed can be a little faster (do not use force). Be careful to fold the cloth neatly, otherwise marks will easily form. When this process is complete, the surface finish is significantly improved.

The custom application of hexagonal guardrail network plays a very important role in the channel slope protection work. According to the performance of the network, it can firmly grasp the soil so that it will not be lost, so the customized slope protection effect of hexagonal guardrail network is very significant, but also because of this advantage, it is widely used in such as channel protection, river bank protection, landslide protection. The custom structure of hexagonal guardrail is tightly combined, the appearance is not concave and convex, and it has satisfactory anti-corrosion, anti-oxygen and other capabilities. Construction without a lot of manpower and material resources, can be in the field of actual operation.

Welding mesh is widely used in industry, agriculture, breeding, construction, transportation, mining and other aspects. Such as machine shields, animal fences, flower fences, window fences, access fences, poultry cages, egg baskets and home office food baskets, paper baskets and decorative. We can make it according to the special requirements of customers. Welding mesh is made of high quality low carbon steel wire row welding, and then cold plating (electroplating), hot plating, PVC plastic coated surface passivation, plasticizing treatment, smooth mesh, uniform mesh, solid solder joint, local machining stable performance, corrosion resistance, corrosion resistance. Features: Stainless steel mesh selection of high quality stainless steel wire row welding, more acid, alkali resistance, solid welding, beautiful, widely used and so on.

This method is generally the use of hot rolled laminated plate as raw material, the annealed steel plate is first sent to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the steel sheet oxygen hot galvanizing method. After pickling, the steel plate immediately enters the tank to soak and wait for galvanized, which can prevent the reoxidation of the steel plate. After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.
