The core difference between Welded H-Beams and hot-rolled H-beams lies in their production processes: hot-rolled H-beams are formed by a single rolling process, while welded H-beams are fabricated by welding steel plates together. The two types differ significantly in production process, performance characteristics, specification flexibility and cost.
Differences in Production Processes
Hot-rolled H-beams
Formed by directly rolling heated steel billets on a universal rolling mill, it is a one-step forming process.
Welded H-beams
Steel plates of appropriate thickness (flange plates and web plates) are cut to the required width and then welded and assembled on a welding machine to form the finished product.
