As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-precision laser-cut special steel shapes in 4140 alloy. Our 10mm thick components deliver exceptional strength and wear resistance, with an edge squareness of 0.2mm and a completely burr-free finish. These features make our parts ideal for demanding applications where accuracy and reliability are critical.
Our 4140 alloy steel offers excellent hardenability, toughness, and fatigue strength. The laser cutting process ensures tight tolerances and clean edges without secondary deburring, saving you time and cost. Each piece is manufactured to your exact specifications, from simple brackets to complex geometrical profiles.
Key Features & Benefits
- Material: 4140 Alloy Steel – High tensile strength, excellent impact resistance, and good machinability after heat treatment.
- Precision Thickness: 10mm – Consistent thickness across all parts ensures uniformity in assemblies.
- Edge Squareness: 0.2mm – Exceptional perpendicularity reduces fitting issues and improves joint integrity.
- Burr-Free Cutting – No sharp edges or burrs, eliminating the need for additional finishing and improving safety.
- Custom Shapes – We can produce almost any contour or hole pattern based on your CAD files.
- Repeatable Accuracy – Laser cutting delivers consistent results even for large production runs.

Frequently Asked Questions
- Q: What is the minimum order quantity (MOQ) for custom laser-cut shapes? A: Our MOQ is flexible – we accept small prototype orders as well as large production runs. Please inquire for specific quantities.
- Q: Can you cut materials other than 4140 steel? A: Yes, we offer laser cutting for various steel grades including carbon steel, stainless steel, and other alloys. 4140 is our specialty for high-strength applications.
- Q: How do you ensure the 0.2mm edge squareness? A: Our fiber laser cutting machines are calibrated regularly, and we use precision fixtures to hold the material during cutting. Post-cut inspection is performed with CMM or other measuring tools.
- Q: Is the burr-free finish guaranteed for all edges? A: Yes, our laser process produces a clean, dross-free edge. For any internal holes or complex contours, we adjust parameters to maintain a burr-free result.
- Q: What file formats do you accept for custom shapes? A: We accept DXF, DWG, STEP, IGES, and PDF. Our team can also convert your sketches into CAD files for a small fee.
- Q: Do you offer heat treatment after laser cutting? A: Yes, we can provide annealing, normalizing, quenching, and tempering services as an optional add-on. Please specify your requirements.
- Q: What is the typical lead time? A: For standard orders, lead time is 7-15 days depending on complexity and quantity. Rush orders are available upon request.
- Q: How do you package the parts for export? A: We use sturdy wooden crates or pallets, with protective layers between parts to prevent scratching. Packaging is suitable for sea freight or air transport.
