Universal Bearing Piles - 305x305x149

Steel universal bearing piles (UCPs) are heavy-duty, "H"-shaped structural steel columns designed specifically to be driven deep into the ground to support massive foundation loads. While they look very similar to standard Universal Columns, bearing piles feature a crucial design difference: their vertical webs and horizontal flanges are manufactured to have the exact same thickness. This uniform thickness allows the pile to withstand the extreme stress and impact of being repeatedly hammered into tough soil or rock without splitting. These robust piles are universally used to create deep foundations for skyscrapers, bridges, docks, and marine structures where the upper soil layers are too weak to support a building.
