Being aware that high-quality production is only possible by
specialized personnel, modern production techniques and full-automated
production, OBIAL zinc-plated steel silos and conveyance equipment are designed
by the product development/design department to address all grain storage
requirements and produced accordingly. High-quality zinc-plated metal sheets
used in silo production resist 450 MPA and are corrosion-resistant. The custom
produced metal sheets used in the production of our silos have a zinc plating
standard of 450 gr/m2 and 350 gr/ m². The zinc plating ratio changes according
to customer demands. OBIAL offers difference silo options, including flat and
conical-bottom silos, starting from a diameter of 4.51 m diameter to 31.60 m. To
be able to carry the vertical loads on the silo, vertical suspension supports
mounted on the silo surface are used to yield maximum strength. OBIAL vertical
suspension supports perfectly distributes the pressure put by the grain in the
silo on the side walls of the silo over the bottom of the silo. To ensure
maximum strength at all joints in OBIAL steel silos, Dacromate 500Acoated
bolts, grade 8,8, are used. To make the silos airtight and waterproof, special
sealing elements are used on metal sheets on the silo frame and on the joints
of upper roof. There are safe access doors that can be easily opened and closed
on the second floors, and observation lids on the roofs of all OBIAL silos. The
silo access door has two layers; the outer layer is made up of single piece of
zinc-plated sheet, and the inner layer is made up of two doors placed one on
top of the other. If the grain fill-level of the silo has gone up the access
door on the silo side wall, the observation lid on the roof allows access into
the silo. In all OBIAL silos, there are inner stairways to enter the silo, a
safety cage external stairway to access silo observation lid on the outer
surface of the silo, and a platform to rest. And there are double-railing and
safety roof stairways on the roofs to be able to reach the top point of the
silos starting from the eaves. OBIAL silo roofs are among the strongest silo
roofs worldwide. OBIAL silo roofs are designed to resist the loads from upper
roof conveyance equipment, snow loads, wind loads and the weight of temperature
cables. The slope of the 30-degree silo roofs ensures an optimum fill level forth
silos. To reinforce the strength and endurance of the upper roofs of wide grain
silos, they are designed as cages using special cross-section profiles. The
strength of the silo roof is maximized thanks to this architecture. The
temperature command system used in OBIAL silos allows us to identify hot spots
and insect activities, freeing our customers from reinstalling the grain
conditions on the screen. The OBIAL temperature command system consists of
temperature cables, temperature sensors installed inside the cables to measure
the grain temperature, and portable or stationary temperature screens. There
are special steel ropes inside the temperature cables, protecting the cables
against elongation. The temperature command system is aligned with the PLC to allow
for controlling the grain temperature inside the silos via the PLC screen.
