Performance Features

01

Roof & Space Structure Design

Space structure roof frames adopt 25° or 30° slopes to ensure structural stability under large loads.
Hot-dip galvanized roof plates feature double-bending ribs that make connections strong, well-sealed, and non-deformable.
Round roof vents measuring 350 mm diameter maintain uniform airflows of 3058 CFM per unit.
Roof ladders with handrails, inspection doors, and perimeter guardrails ensure safe maintenance operations for site personnel.
Customized polyurethane insulation shells and top distribution devices enhance multi-season climate control and uniform material filling.

02

Corrugated Sidewalls & W-Shaped Stiffeners

Sidewall sheets are manufactured from high-tensile S350GD galvanized steel with tensile strength reaching up to 440 MPa.
Sidewall sheets feature 80 mm wave distance and 14.5 mm crest height, laminated together for greater structural strength.
External W-shaped stiffeners made of Q335 steel carry nearly twice the weight of traditional Z-shaped stiffeners.
Grade 8.8 and 10.9 waterproof bolts are configured in 3, 5, or 9 rows for load distribution.
Customized 310g/m² Magnesium-Aluminum-Zinc alloy coatings provide superior anti-corrosion protection for highly corrosive storage environments.

03

Aeration Floor & Sweep Auger Unloading

Fully automatic hydraulic drive sweep augers reliably clear residual grain in flat silos up to 30.2 m diameter.
Aeration floor plates are offered in I-beam, Wind symbol, and Earth profiles with 2 mm perforation holes.
Heavy galvanized centrifugal fans provide powerful ventilation volumes up to 32,380 m³/h with extended motor operational lifespan.
Manhole access doors measuring 600x700 mm and climsilog ladders with safety cages facilitate convenient inner silo entry.

FAQ

What is the maximum storage capacity available in Flat Bottom Silos?
Flat bottom silos offer single-silo storage capacities up to 17,000 MT (calculated at 0.75 t/m³ density) with a maximum silo diameter of 30.2 m.
How does the sweep auger handle cleanout in large flat bottom silos?
Flat bottom silos utilize a fully automatic hydraulic drive sweep auger that operates after grain gravity self-flow ends, thoroughly clearing residual material in silos up to 30.2 m diameter.
What corrosion protection options are available for harsh atmospheric conditions?
GSS utilizes S350GD galvanized steel with standard Z275, Z350, Z450, and Z600 galvanizing grades (EN 10346 / ASTM G90-G210), alongside an optional 310g/m² Magnesium-Aluminum-Zinc coating for extended corrosion resistance.
