Q: What processing services can be provided for Q355 plate?
A: We can provide the following processing services:
Cutting: flame cutting, plasma cutting, laser cutting, water jet cutting
Drilling: drilling holes of various specifications according to the drawing
Bending: bending into various shapes such as plates, angles, and arcs
Welding: welding into structural parts according to the drawing
Surface treatment: painting, galvanizing, shot blasting, etc.**
Q: What is the difference between flame cutting and plasma cutting of Q355 plate?
A: - Flame cutting: suitable for plates with thickness >6mm, low cutting cost, but low precision (error ±1mm), and the cutting surface has a certain roughness.
Plasma cutting: suitable for plates with thickness ≤20mm, high cutting precision (error ±0.5mm), smooth cutting surface, fast cutting speed, but higher cost than flame cutting.For plates with thickness >20mm and high precision requirements, water jet cutting is recommended.**
