Things You Should Consider During Steel Silo Manufacturing Process

Flyer steel silo, with its continuous development of more than 30 years, has been quickly spread and popularized all over the world. As a new type of silo, steel silo is widely applied in each link during the process of grain storage and transportation, and has successfully become a symbol of modernization in both bulk and grain storage industry. All the above achievements depend on the three superiorities of its functions.

Economy: Steel silo keeps the lowest construction cost among all types of silos, both for the silo body and the foundation, which is only half of the construction cost of concrete silo and four fifths of the brick-construction structure. It will steadily decline due to the decreasing price of steel.

Adaptability: Steel silo enjoys excellent performance on mechanization and automation of grain storage, such as grain harvest and transport, monitoring, management as well as the ventilating and temperature management of the condition of stored grain.

Establishment: Steel silo enjoys high establishing for its simple requirement on foundation, quick construction speed on establishing, and free from natural elements’ effects. After having investigated on the superiorities of steel silo, customers list following suggestions during its manufacturing:

• Materials: Commonly, steel silo is manufactured by popular models steel. Steel Q235 is the best choice for its convenient in purchase and low in cost. If the calculation thickness of steel exceeds the production capacity of equipment, low-alloy steel will be a better substitute. What’s more the steel is usually galvanized to meet the requirement of anticorrosion. Therefore, zinc coating becomes a vital factor of steel silo construction, which will directly effect on its serving life. China keeps the same standard of zinc coating with foreign countries which is 400g per square meters.
• Style: Spiral steel silo and assembly silo are two prevalent styles of thin-walled steel silo. Both of them possess their own features due to their different structures.
  The features of spiral steel silos are:
  1. It is manufactured by hot dip galvanized sheet so that the color of its undercutting is evenly.
  2. It can be applied for storing liquid materials like water and oil for its excellent performance on air tightness.
  3. The sheet used for spiral steel silo should be thicker than that for assembly silo for its internal wall is lubricated.
  The features of assembly silos are:
  
  1. It can be manufactured by both hot dip galvanized coil or sheet and galvanized sheet. So it is more convenient on purchasing material.
  2. All the components of the assembly silo are standard, so they are replaceable if damaged or rusted during its serving life.
  3. It is developable and transferable which can best meet the special requirement of customers who are renting field.
  4. Its pillar can be installed outside, which is favorable for grain storage.
  5. It can meet the standard requirement of air tightness after caulking by silicone because its own air tightness is unideal.
  6. It can be manufactured as double insulation construction with little increase on cost.
• Foundation: Basically, there are two types of steel silo foundation, plat form and hopper. Plat foundation silo is widely applied in steel silos of larger diameter which sweeper should be installed on the bottom inside. Plat foundation steel silo is featured by easy constructed and lower cost. Meanwhile, hopper foundation steel silo enjoys great popularity when customers are considering about grain unloading artesian. There are three hopper types like full steel hopper, semi-steel hopper, and cement hopper. Generally, there is no big difference in application of these three different hopper types. However, a special type of cement hopper constructed by backfilling, although requiring much easier construction process, is a big waste on raw material and silo capacity and requires a large civil engineering quantity.

As suggested above, customers should take comprehensive consideration before making choice to maximize the function price ratio and to perfect the investment results.
