Laser cutting for sheet steel is a method that uses a fiber laser beam to cut through carbon steel or high-strength steel along a programmed profile; achievable thickness depends on machine power, commonly ranging from under 20mm up to under 30mm.
Kim Phat cuts sheet steel (mild steel, high-strength steel, galvanized steel) on 3kW and 6kW fiber laser machines, handling both small sample orders and bulk factory orders.
Cuttable thickness and processing speed depend on the machine power used - the table below lists the thickness limit per machine so customers can check before sending a file.
| Cutting machine | Bed size | Maximum steel thickness |
|---|---|---|
| 3kW fiber laser (2 machines) | 3,000 x 1,500 mm | Under 20mm |
| 6kW fiber laser (1 machine) | 6,000 x 1,500 mm | Under 30mm |
The thickness figures are machine power limits; actual cutting capability for each part also depends on shape and precision requirements, confirmed at the time of quoting.
Why choose laser cutting for sheet steel
Compared to plasma cutting or manual cutting, CNC laser cutting keeps the cut edge sharp, holds a smaller tolerance, and needs less edge rework, suited to parts that require precise assembly or complex profiles.

Frequently asked questions about laser cutting for sheet steel
What is the maximum thickness of sheet steel you can cut?
The 6kW machine cuts sheet steel under 30mm; the 3kW machine suits sheet steel under 20mm. For thick, complex-profile parts, Kim Phat confirms specific cutting capability when the file is received.
Does laser-cut sheet steel need edge rework?
For most applications, the laser-cut edge is sharp enough for direct assembly with no regrinding needed. Some parts requiring a high surface finish may need extra processing.
Do you accept small quantity orders?
Yes, Kim Phat accepts both small sample orders and bulk long-term contract orders.
