Being aware that high-quality production is only possible byspecialized personnel, modern production techniques and full-automatedproduction, OBIAL zinc-plated steel silos and conveyance equipment are designedby the product development/design department to address all grain storagerequirements and produced accordingly. High-quality zinc-plated metal sheetsused in silo production resist 450 MPA and are corrosion-resistant. The customproduced metal sheets used in the production of our silos have a zinc platingstandard of 450 gr/m2 and 350 gr/ m². The zinc plating ratio changes accordingto customer demands. OBIAL offers difference silo options, including flat andconical-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 suspensionsupports mounted on the silo surface are used to yield maximum strength. OBIALvertical suspension supports perfectly distributes the pressure put by thegrain in the silo on the side walls of the silo over the bottom of the silo. Toensure maximum strength at all joints in OBIAL steel silos, Dacromet 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 thejoints of upper roof. There are safe access doors that can be easily opened andclosed on the second floors, and observation lids on the roofs of all OBIALsilos. The silo access door has two layers; the outer layer is made up of asingle piece of zinc-plated sheet, and the inner layer is made up of two doorsplaced one on top of the other. If the grain fill-level of the silo has gone upthe access door on the silo side wall, the observation lid on the roof allowsaccess into the silo. In all OBIAL silos, there are inner stairways to enterthe silo, a safety cage external stairway to access silo observation lid on theouter surface of the silo, and a platform to rest. And there are double-railingand safety roof stairways on the roofs to be able to reach the top point of thesilos starting from the eaves. OBIAL silo roofs are among the strongest siloroofs worldwide. OBIAL silo roofs are designed to resist the loads from upperroof conveyance equipment, snow loads, wind loads and the weight of temperaturecables. The slope of the 30 degree silo roofs ensures an optimum fill level forthe silos. To reinforce the strength and endurance of the upper roofs of widegrain silos, they are designed as cages using special cross-section profiles.The strength of the silo roof is maximized thanks to this architecture. Thetemperature command system used in OBIAL silos allows us to identify hot spotsand insect activities, freeing our customers from reinstalling the grainconditions on the screen. The OBIAL temperature command system consists oftemperature cables, temperature sensors installed inside the cables to measurethe grain temperature, and portable or stationary temperature screens. Thereare special steel ropes inside the temperature cables, protecting the cablesagainst elongation. The temperature command system is aligned with the PLC toallow for controlling the grain temperature inside the silos via the PLCscreen.
