Steel Chassis for Steel Coil Transportation - Large Fabrication ServicesAfter hot rolling, steel coils are usually placed on the floor for the cooling process, then carried to the warehouse or shipping area once cool. The large steel chassis pictured here is specially designed to allow the coil to load directly on its V-shape top, so that when needed, a semi-tractor can go directly beneath the chassis, lift it up, and go where the coils are needed.
