Steel corrosion, commonly referred to as rust, is an oxidization process occurring when iron in steel is exposed to oxygen and water. Rust causes steel to thin over time, reducing its strength and causing product failure.
Any coating, which provides a barrier to moisture and oxygen, protects steel from corrosion. A painted surface provides an effective barrier until it is broken allowing moisture and oxygen to come in contact with the steel beneath. Rust develops at the breakage point and can even extend under the protective paint barrier.
Similar to paint, a galvanized coating forms a protective barrier to protect steel from moisture and oxygen. Galvanized coatings also provide a second method of protecting steel by electrochemically “sacrificing” the zinc in the present of corrosive elements. In other words, the zinc corrodes, until it is depleted, instead of the metal underneath. Because it is physically bonded to the metal, galvanized coating does not allow rust to extend beneath its surface.
Galvanized coatings are expressed in ounces per square ft with conventional coatings designated as G30, G40, G60, and G90. These refer to thickness of .30, .40, .60 and 90 oz./ft2, respectively. Corrosion resistance is directly proportionate to the amount of zinc coating on the steel. Therefore we would expect the service life of G90 steel to be roughly three times that of G30 in the same environment. Likewise, increasing the galvanized coating on a feed bin from G90 to G100 increases the bin’s service life by 10%.
Galvanized steel is an excellent choice for use in feed bin fabrication, as it does not degrade when exposed to the sun’s ultraviolet rays like painted coatings or poly bins.
In addition to heavier galvanized coatings, Hog Slat bins are manufactured from stronger Grade 55 steel, come with an improved ladder design and water deflecting Weather Edge™. Every bin is backed by an extended 5-year warranty. To see more go to Bulk Feed Bins.
To the best of my knowledge, when we built them in 1989, these were the first tunnel/natural ventilated houses constructed in the state,” explained Rodney Bowden at his family farm near Clinton, NC. “We’ve always had good results in the buildings, but the recent upgrades have improved our performance.”
Rodney added two GrowerSELECT 54″ AirStorm fans per house to increase airspeed and reduce the ambient temperature. The durable AirStorm 54″ fans feature a fiberglass housing, plastic shutters, and a stainless steel prop.
The next step in the upgrade was to replace the original feed pans with GrowerSELECT Classic Flood feeders. Rodney said, “Installing the new pans helps minimize wasted feed when the birds are young and has improved my feed conversion during grow out.”
These investments have paid off with an increased bird performance and helped Rodney settle in first place among his group several times since the upgrade.

“Our old feeders just weren’t allowing us to compete with some of the newer barns around the area. Our very first flock with new Classic Flood feeders settled at # 1″, explained Exeter, MO grower, C.L. England.
“We felt like changing out the feeders in our 29-year old buildings was a cost effective way to lower our production costs. We proved that out with .2 improvement in feed conversion on the first flock.”
“One of the biggest factors is probably the flood feature of the new pans. With our old pans, we had to hand-fill feeders with extra feed when starting a flock. With the Classic Flood feeders, we just drop the feeders and the pans fill with feed automatically. Getting extra feed into the chicks at the start makes a big difference at settlement.”
“I’m pleased we made the change as it appears it’s an investment that will pay us back quickly,” said C.L.
How can we make the claim of selling the strongest, heaviest feed bins on the market at the best possible price to swine and poultry growers?
Simple. Our direct distribution system eliminates the additional markup that dealers have to add to the bin’s price. Instead, that money goes back into building a stronger bin manufactured from heavier steel. These longer lasting bins are built with 5-10% more steel, by weight, than competitive brands.
Compare the features.
Most manufacturers only use 50,000 psi structural steel for the bin sheets and legs to reduce costs. Hog Slat bins are constructed entirely of GRADE 55 structural steel. The bin sheets, legs, roof sheets, bottom cone sheets…the entire bin.
The bottom cone sheets of a bin are subjected to extra abuse from hammers and mallets used to dislodge bridging feed. That’s why we used thicker steel to resist dings and dents.
We build the bin collar out of heavier 10 gauge steel to eliminate having to add additional reinforcing collars. The collar is stamped to reduce variations in dimensions compared to rolled or spun collars.
Every Hog Slat / Georgia Poultry bin is manufactured in-house for complete control of raw material purchasing and manufacturing operations. Our facility includes state-of-art rolling, stamping and finishing machinery to ensure precise fit and finish.
I recently had a chance to look through some old books of my father’s and ran across The Yearbook of Agriculture, 1960 edition called Power to Produce. The forward from this book reads:
“The value of this book is to bring into sharp focus the technological revolution that is now changing not only agriculture but our way of life.” and “we must make the most of the extra food technological advances provide.”
In the middle of the book, I found these two images. Black and white photos of the latest in 1960 agricultural technology for laying hens. It looks a lot like current “cage-free” egg production to me.
Floyd Smith, Waseon, Ohio, shown in the photograph above, demonstrates how dry the litter is in his poultry house when temperatures were below zero degrees outside and about 55° F inside. The insulated windows make the most of the wintertime sunshine to reduce moisture and keep temperatures even.
The pole-type, prefabricated-steel laying house pictured below has a slat floor, mechanized feeder, fiberglass insulation, and an interior lining of corrugated galvanized steel sheets. The central ridge ventilator with turnabout fans supply up to 6 c.f.m. per bird. The building is 48 by 64 feet, has an egg room and work room 12 by 32 feet.
This was the time period when augers to fill feeders and automated water systems were the latest technology and began to replace hand labor. Confinement systems were beginning to be developed to allow fewer farmers to provide more food to a growing urban population.
Hog Slat and Georgia Poultry are in the business of providing egg producers with the latest options for producing “cage-free” eggs. Give us a call today at 800-949-4647.
