About This Service
Oxy-fuel cutting is one of the most established and economical methods for processing thick carbon steel plates. It uses a combination of preheating flames from fuels such as acetylene or propane and a concentrated stream of oxygen to oxidize and blow away molten material. This method is particularly well-suited to heavy-duty applications where other processes like laser or plasma become too costly or technically impractical. By relying on robust equipment and a proven chemical process, oxy-fuel provides unmatched efficiency when handling extremely thick sections, often ranging from 20 mm to well above 300 mm.
One of the greatest advantages of oxy-fuel cutting lies in its scalability and adaptability to field operations. Unlike other precision-based cutting systems that are confined to workshop environments, oxy-fuel torches can be mobilized easily for onsite projects such as shipbuilding, structural steel erection, and heavy fabrication yards. This makes it a preferred choice for industries that require flexibility and durability under challenging conditions, including outdoor or rough-weather settings. The portability of equipment ensures minimal downtime, even when working on large plates or oversized profiles.
Beyond simple straight-line cuts, oxy-fuel cutting allows bevel cutting in V, Y, and K profiles, which is essential for weld preparation. With precise control over torch angles and gas flow, operators can achieve consistent bevels and maintain reliable dimensional accuracy. The process also supports marking functions, enabling fabricators to combine cutting and part marking in a single workflow. This efficiency not only saves time but also reduces handling errors in subsequent fabrication stages.
From an economic standpoint, oxy-fuel cutting remains unmatched for thick-section steel. The consumables are low-cost, the equipment is straightforward to maintain, and the repeatability of results makes it a dependable solution for high-volume or project-based operations. Whether applied to base plates, gussets, flanges, or heavy profiles, oxy-fuel cutting continues to be the industry’s go-to choice for cost-effective, large-scale steel processing.
