Custom Design & Engineering Support

Working from concepts, sketches, or existing designs, our engineering team evaluates CAD drawings for load-bearing requirements, cable routing feasibility, and marine environment optimization.

Through Design-for-Manufacturing reviews and material selection guidance, we transform complex marine concepts into manufacturable, high-performance structures that balance strength, corrosion resistance, and aesthetic finish.

Precision Tube Fabrication & Welding Expertise

Behind every smooth curve and strong joint is a process you can measure. We integrate CNC mandrel bending, laser cutting, and TIG/MIG welding into a seamless production workflow.

CNC Tube Bending

Mandrel bending for complex curves with minimal ovality. Typical tolerances ±0.3–0.8 mm depending on diameter and CLR.

Laser Tube Cutting

Precision cutting with mounting holes, slots, and miters prepared in one setup. Tolerances ±0.05–0.1 mm for critical interfaces.

TIG/MIG Welding

Fixture-controlled welding for dimensional accuracy across all angles. 100% visual inspection with sample NDT available.

Marine-Grade Materials & Corrosion Control

Material Options

Saltwater environments demand proven materials and finishing processes. We specialize in marine-grade stainless steel and aluminum with protective surface treatments.

316 Stainless Steel — Superior corrosion resistance for offshore exposure
304 Stainless Steel — Cost-effective option for protected marine environments
6061-T6 Aluminum — Lightweight with excellent strength-to-weight ratio
5083 Marine Aluminum — Maximum corrosion resistance for saltwater applications

Material selection guidance provided during DFM review based on structure size, environment, and budget.

Surface Finishing

Mirror Polishing — High-gloss stainless finish for premium aesthetics
Brushed/Satin Finish — Professional appearance with reduced maintenance
Anodizing (Type II/III) — Hard-coat protection for aluminum structures
Powder Coating — Custom colors with UV and salt resistance

Every surface treatment is selected for long-lasting protection, uniform appearance, and ease of maintenance in marine conditions.

Integrated Functional Structures

Beyond standard arches, we fabricate integrated systems combining multiple functions into one precision-engineered structure.

Davits & Lifting Systems

Integrated davit structures for dinghy launching with proper load distribution and mounting reinforcement.

Solar Panel Mounts

Adjustable solar mounting systems with cable routing channels built directly into arch structure.

Equipment Brackets

Custom mounting plates for radar, antennas, navigation lights, and other marine electronics.

Why Partner with X-KPR

When complex marine structures need to move from design to production-ready assemblies, X-KPR brings engineering rigor, integrated capabilities, and proven quality systems.

Engineering-First Approach

We act as an extension of your design team, not just a fabricator. DFM feedback within 48h helps de-risk designs before production starts.

End-to-End Integration

Tube bending, laser cutting, welding, surface finishing, and quality inspection under one roof. Fewer handoffs mean faster delivery and consistent quality.

Marine-Grade Expertise

Proven performance in stainless steel and aluminum marine structures with corrosion-resistant finishing and structural validation for offshore environments.

Frequently Asked Questions

What materials are recommended for radar arches?

316 stainless steel or marine-grade aluminum (5083/6061) are preferred for saltwater environments. 316 SS offers superior corrosion resistance for offshore exposure. Marine aluminum provides excellent strength-to-weight ratio with proper anodizing. Material choice depends on structure size, desired finish, and budget — guidance provided during DFM review.

Can you fabricate custom mounting configurations?

Yes. Every arch is custom-built from your CAD drawings with mounting points, equipment brackets, and cable routing adapted to your vessel specifications. Our engineering team reviews mounting loads and interface requirements during the DFM process.

Do you integrate accessories like solar mounts or davits?

Yes. We fabricate integrated structures combining radar arches with davits, solar panel mounts, navigation lights, and antenna brackets as one assembly. This eliminates alignment issues and reduces installation time compared to separately mounted components.

What is the typical lead time?

From 7–10 business days after design approval, depending on complexity and finishing requirements. This includes fabrication, welding, surface treatment, and final inspection. Expedited timelines available on request for urgent projects.

What quality records can you provide?

We provide First Article Inspection (FAI) reports, in-process inspection logs, dimensional verification records, and Certificates of Conformance (CoC). Material certifications and Certificate of Analysis (CoA) available on request. All records traceable through our ISO 9001 quality management system.
