Custom Marine Hardtops Manufacturer | X-KPR Marine

Custom Design & Engineering Support

We work from your CAD drawings or concepts to design hardtops optimized for structural strength, weatherproofing, and electronics integration.

Our team provides DFM feedback on cable management routing, window sealing, and load-bearing structures to ensure long-term durability in marine environments.

Drainage system design (prevent water pooling)
Cable management routing (waterproof entry points)
Structural load analysis (equipment weight + wind load)
Window sealing groove specifications (compatibility with marine glass)

Engineering Review Process

We analyze drainage design, structural load paths (equipment + wind), and panel mounting methods to prevent water ingress and ensure equipment safety.

Workflow: Upload design → 48h DFM feedback → Quote with structural notes → Prototype or production

Frequently Asked Questions

What materials are used for marine hardtops?

316L stainless steel tube frames for corrosion resistance, 5052 aluminum panels for lightweight strength, and marine-grade glass windows. Material selection depends on application and customer requirements.

Can you integrate electronics mounting?

Yes, we design cable management channels, mounting brackets for radar/GPS, and waterproof cable entry points during fabrication. Provide equipment specifications for precise integration.

What is the typical lead time?

10-15 business days after drawing confirmation, depending on panel size and window integration complexity. Rush orders available on request.

Do you provide window installation?

We fabricate precision aluminum frames with sealing grooves. Glass windows are sourced separately but we ensure frame compatibility with standard marine glass specifications.

What tolerances for frame assembly?

Frame tolerances: ±0.5-1.0mm. Window groove tolerances: ±0.3mm for proper sealing. All dimensions confirmed at quote stage.
