Accepted Answer

We deliver nationwide. Free shipping in Binh Duong. Same-day delivery to HCMC and Dong Nai. Other provinces via express courier services.

Question 5

What materials do you stock?

Accepted Answer

We stock over 16 materials: SUS 304/316 stainless, SS400 mild steel, 5052/6061 aluminum, galvanized, C1100 copper, brass. Thicknesses from 0.5mm to 25mm.

Question 6

What is the maximum cutting thickness?

Accepted Answer

Mild steel: 25mm, Stainless: 12mm, Aluminum: 10mm, Copper: 6mm. Maximum sheet size: 3000 × 1500mm.

Question 7

Can you do custom colors for powder coating?

Accepted Answer

Yes. We offer powder coating in 200+ standard RAL colors. Custom color matching is available for orders of 50+ pieces.

Question 8

What payment methods do you accept?

Accepted Answer

We accept bank transfer, cash, and online payment. New orders: 50% deposit, 50% on delivery. Regular customers: end-of-month payment terms.

Question 9

Does the price include material?

Accepted Answer

Yes. Our quoted price includes material, fabrication, and basic deburring. Additional services like bending, welding, and coating are itemized separately in the quote.

Question 10

Do you offer volume discounts?

Accepted Answer

Yes. Volume pricing: 10+ pieces save 15%, 50+ save 30%, 100+ save up to 50%, 500+ save up to 79%. Contact us for the best price on your quantity.

Question 11

What is your standard lead time?

Accepted Answer

Standard production is 5-7 working days after order confirmation. Rush orders can be completed in 2-3 days with additional charges. Complex assemblies may require longer lead times.

Question 12

What are your cutting tolerances?

Accepted Answer

Our fiber laser cutting achieves ±0.1mm tolerance on most materials. For CNC bending, we maintain ±0.5° angle accuracy. Specific tolerances depend on material type and thickness.

Question 13

Can you handle rush orders?

Accepted Answer

Yes. Rush production completes in 2-3 days with a surcharge. In special cases, 24-hour turnaround is possible. Contact us directly to arrange.

Question 14

What is your quality control process?

Accepted Answer

Every part is dimensionally checked with precision measuring tools, visually inspected for surface quality, and compared against reference samples. Large orders follow AQL standards.

Question 15

Do you offer assembly services?

Accepted Answer

Yes. We provide weld assembly, hardware insertion (screws, rivets, inserts), and surface finishing. Products are delivered ready-to-use.

Question 16

Do you offer design assistance?

Accepted Answer

Yes! Our engineering team can help optimize your design for manufacturing (DFM), suggest material alternatives, and ensure your parts are producible at the best cost.

Question 17

Which CAD file format gives the best results?

Accepted Answer

2D DXF files give the best results. Use separate layers for cutting, bending, and marking. Ensure dimensions are in mm at 1:1 scale. We also accept DWG, STEP, STP, and PDF.

Question 18

Do you support 3D design files?

Accepted Answer

We support flat pattern extraction from 3D STEP/STP files. If you need design from scratch, our engineers can create drawings from sketches or descriptions.

Question 19

What is the minimum bend radius?

Accepted Answer

Minimum inside bend radius equals the material thickness. Example: 2mm sheet → minimum bend radius 2mm. For harder materials (stainless, 6061 aluminum), use a larger radius.

Question 20

Which CAD software is compatible?

Accepted Answer

All popular CAD software: AutoCAD, SolidWorks, Inventor, Fusion 360, FreeCAD, Onshape. Export as DXF or STEP for best results.

Question 21

Do you accept small orders for custom laser cutting?

Accepted Answer

Yes! We accept custom laser cutting orders from just 1 piece — no minimum order quantity. Whether you need a prototype or mass production, simply upload your CAD file to get an instant quote.

Question 22

How much does stainless steel 304 laser cutting cost?

Accepted Answer

SUS 304 laser cutting pricing depends on thickness and geometry. Reference: 1mm from 8,000 VND/m, 2mm from 10,000-15,000 VND/m, 3mm from 18,000-25,000 VND/m. Upload your CAD file for exact pricing.

Question 23

Is laser cutting more accurate than plasma cutting?

Accepted Answer

Yes. Fiber laser achieves ±0.1mm tolerance, while plasma only reaches ±0.5-1mm. Laser produces cleaner edges with minimal burr, requiring no secondary processing. However, plasma is more cost-effective for steel over 20mm thick.

Question 24

What is the delivery time for laser cutting?

Accepted Answer

Standard delivery is 5-7 business days. Rush orders can be completed in 2-3 days. Simple laser-cut-only jobs (no bending/welding) can ship even faster. Free shipping within Binh Duong province.
