ISO 9001:2015 Certified

Our quality management system meets international standards for consistent product excellence.

CE Marking

All products comply with EU safety, health, and environmental protection requirements.

RoHS Compliant

Our MGN20 rails are free from hazardous substances, meeting global electronics standards.

REACH Certified

Full compliance with EU chemical regulations for safe, sustainable manufacturing.

A: The MGN20H features a higher load capacity and improved rigidity compared to standard MGN20. The "H" variant has a taller profile (20mm vs. 15mm for standard MGN20) and can handle 40% more load while maintaining the same 20mm width. Ideal for high-speed or heavy-duty applications.

A: Absolutely. We offer custom cutting from 100mm to 6,000mm with ±0.1mm length tolerance. No minimum order quantity for custom lengths. For bulk orders, we can also provide pre-drilled and tapped rails to your specifications.

A: We offer several coating options:

• Standard: Natural steel (no coating)
• DLC (Diamond-Like Carbon): Reduces friction by 40%, extends lifespan by 3x. Ideal for high-speed applications.
• Black Oxide: Improves corrosion resistance and reduces glare.
• Zinc Plating: Budget-friendly corrosion protection for indoor use.
• Stainless Steel: For food-grade or medical applications requiring FDA compliance.

A: The number of rails depends on your load requirements and precision needs:

• Light-duty (0-500N): 1 rail with 1 block
• Medium-duty (500-2000N): 2 parallel rails with 2-4 blocks
• Heavy-duty (2000N+): 2-4 rails with multiple blocks per rail

Our engineers can provide free CAD models and load calculations for your specific application. Request a consultation.

A: Our minimum order quantity (MOQ) is just 1 set (1 rail + 1 block) for standard products. For custom orders (special lengths, coatings, or materials), the MOQ is 10 sets. Sample orders are welcome with no MOQ.

A: We implement a multi-stage quality control process:

• Raw Material Inspection: 100% testing of steel hardness and composition.
• Machining Precision: In-process checks every 2 hours using Mitutoyo CMMs.
• Assembly Testing: Each rail is tested with its block for smoothness and load capacity.
• Final Inspection: 100% visual and dimensional checks before packaging.
• Batch Traceability: Every product has a unique QR code linking to its inspection report.

Our defect rate is <0.1% - among the lowest in the industry.

A: We offer flexible terms to accommodate your needs:

Payment:

• Sample Orders: 100% TT in advance
• Bulk Orders: 30% deposit, 70% before shipment (TT or LC)
• Long-term Partners: 30-60 day credit terms (subject to approval)
• Accepted Methods: TT, LC, PayPal, Credit Card, Western Union

Shipping:

• Air Freight: 3-7 days (for urgent orders)
• Sea Freight: 20-35 days (most cost-effective)
• Express (DHL/FedEx): 2-5 days (for samples)
• Free Shipping: For orders over $5,000
