Glass Lined Steel Grain Storage Silos for Dry Bulk Storage with NSF / ANSI 69 Certification

Glass Lined Steel Silo for Grain / Dry Bulk Storage with NSF / ANSI 69 Certification

When come to a storage project, we would have a question: What kind of storage should I choose? Warehouse, concrete silos,Glass-fused-to-steel silos? Therefore, we make an comparison between the concrete silo and GFS silo as below:

Production process.

§ All parts such as enamel panels and accessories are manufactured in a factory, so the quality can be totally controlled, whereas cast in place concrete silos involve more variables such as concrete delivery and weather.

Design.

§ Concrete silos can be taller than enamel steel silos but these ones have bigger diameters so the total capacity is highest. For this reason concrete silos are only more suitable when the space is really limited.

§ It is easier to erect enamel silos and also to install accessories like doors, ladders, samplers, etc.

§ Steel structure is more flexible, so steel silos have better behavior in case of earthquake.

§ Regarding airtight, both structures are normally airtight if the roof are properly sealed. GFS steel silo by Center Enamel can be equipped with GFS roof which can ensure the best air tightness. So enamel steel silo is more preferred for some grain storages needing great air tightness.

Cost.

§ GFS silos are very easy to be removed, dismantled and expanded. Compared with concrete silos, enamel steel silos can help the user to save much more cost as the concrete silos have a long-termed construction period, complicated construction process and difficult maintenance. These will bring more costs for the user.

Foundation.

§ Steel silos do not require the soil to be as firm in order to support the weight of the structure. Sometimes steel silos can be built on land that doesn’t have the higher load-bearing capacity needed for concrete.

There are many details and variables in silo projects and every type of grain storage has pros and cons. The right choice is the one that fits in your infrastructure strategy.

Here is the chart indicating the difference between the concrete tank and the enamel tank:
