Get the right Sukup grain bins for your setup. When comparing grain bin roof ratings, take note of the snow loads the ratings are based on. Some companies are claiming an 8000 lb peak load rating, but are basing their roof ratings on 30 psf snow loads. Sukup has a 5000 lb peak load rating with a 40 psf snow load. Looking at the chart below, it’s plain to see that, if you compare apples to apples, the Sukup roof is much stronger (12,276 lb. equivalent roof load on a 36′ bin and almost 18,000 lb. equivalent roof load on a 48′, using the 30 psf snow load) than our competitor’s, who is claiming an 8000 lb. peak load with a 30 psf snow load.
