RV & Van Conversion

Custom Metal Hardware for RV OEM Manufacturers and Van Conversion Programs

Any fabricator can claim OEM-grade quality. Not many can prove it in an environment where every shortcut shows up within a season. PW Marine OEM has spent 15+ years supplying custom stainless and aluminum hardware to production boat builders operating in saltwater — the most unforgiving corrosion environment production metal hardware encounters. PMI-verified material grades. Qualified TIG weld procedures. ASTM B117-tested corrosion protection. Complete quality documentation on every program. We didn't build these processes to win certifications. We built them because the marine environment demands them.

Your RV or van conversion program operates in a less demanding environment than saltwater. That's exactly what makes a marine OEM supplier your best option. UV exposure, road chemicals, thermal cycling, and structural loads — these are all subsets of what we already deliver to. The fabrication standard, quality processes, and material verification systems that meet marine OEM requirements don't get adjusted for RV and van programs. You get everything that standard demands — because it's the only standard we run.

Weight matters in RV and van programs. Every pound of hardware consumes payload budget, affects fuel economy, and in van conversions contributes to GVWR calculations. Marine hardware was engineered with weight budget as a hard constraint — T-top systems must be light enough not to affect vessel stability, strong enough to carry load, and corrosion-resistant enough for years of outdoor exposure. That engineering discipline — weight, strength, and corrosion resistance optimized simultaneously — is exactly what RV and van hardware programs require. We've been solving that problem for boat builders. We apply the same solution to your program.

Why a Marine OEM Supplier Is Your Best Option
Any fabricator can claim OEM-grade quality. Not many can prove it in an environment where every shortcut shows up within a season. PW Marine OEM built its fabrication processes — PMI material verification, qualified TIG weld procedures, ASTM B117-tested corrosion protection, complete quality documentation — to supply production boat builders operating in saltwater. That's the most unforgiving corrosion environment production metal hardware encounters. We didn't build these standards to win certifications. We built them because the marine environment demands them. Your RV or van conversion program operates in a less demanding environment. You'll still get everything that standard demands — because it's the only standard we run.

What We Build for RV OEM and Van Conversion Programs

We supply fabricated stainless and aluminum components across all metal hardware categories that production RV and van programs require. Programs typically start with one category and expand as quality and delivery reliability are established.

Component Categories

Category
Specific Components
Exterior Structural Hardware
Roof rack systems and frames, ladder mounts, hitch attachment hardware, structural body attachments, and antenna/accessory mounts — weight-optimized 6061-T6 aluminum or 316 stainless, ASTM B117 finish-verified
Interior Mounting Systems
Cabinetry brackets and anchor points, appliance mount frames, wall and floor track systems, fold-down hardware, and structural interior attachment hardware — dimensionally consistent for production installation efficiency
Chassis & Structural Components
Crossmembers, support brackets, body-to-chassis attachment hardware, and structural reinforcements — fabricated to drawing tolerances with qualified TIG weld procedures and PMI material verification
Aesthetic & Trim Hardware
Handles, hinges, vent frames, guards, and decorative stainless or anodized aluminum trim — surface finish quality to specification, consistent appearance across production units
Kitted Assembly Programs
Multi-component hardware kits assembled and labeled for production line installation — reduces inbound assembly labor, eliminates per-part incoming inspection overhead, and delivers installation-ready packages

Weight Optimization Across Your Hardware BOM

Weight optimization is a design discipline, not a parts substitution exercise. PW Marine OEM applies DFM review to hardware programs to identify alloy substitution opportunities, geometry optimizations, and finish specification calibrations across the full hardware BOM — before tooling investment.

A full-BOM weight optimization analysis on a typical van conversion hardware package identifies 20–35% total weight reduction opportunity versus catalog-default hardware selections. At 30 lbs total hardware weight, that's 6–10 lbs of available payload currently consumed by overspecified hardware. For programs with tight GVWR budgets, that margin matters. For RV OEM manufacturers managing weight specifications across a model line, it accumulates quickly.

Alloy Selection by Application

Application
Recommended Alloy & Rationale
Roof rack frames and rails
6061-T6 aluminum tube/extrusion — 40 ksi yield strength, 65% lighter than steel equivalent, weldable
Structural attachment brackets
6061-T6 aluminum plate — structural load path, PMI-verified on every lot
Ladder mounts and exterior fittings
316 stainless or 6061-T6 — 316 for high corrosion environments, 6061 where weight budget is constrained
Interior cabinetry rails and tracks
6063-T5 aluminum extrusion — surface finish quality priority, adequate strength for interior loads
Chassis brackets and crossmembers
6061-T6 aluminum or mild steel — steel where chassis weld integration requires it, aluminum where weight budget allows
Aesthetic trim and hardware
6063-T5 anodized or 304/316 stainless per exposure level and finish specification

OEM Fabrication Process — From Drawing to Production Release

Our manufacturing process is built for OEM production programs. Process controls are documented, tooling is qualified, and quality records follow every component from incoming material verification to finished deliverable.

Stage
What Happens
DFM Review
Drawing reviewed against production process — tolerance achievability, weld joint access, finishing coverage, weight optimization opportunity, assembly interface fit
Prototype / First Article
First production part fully inspected against all drawing callouts. PMI on incoming material. Finish qualification including ASTM B117 on exterior hardware. Pass/fail documented.
Production Tooling
Fixtures, jigs, and CNC programs qualified to first article dimensions. Setup documentation completed before production release.
Pilot Run
10–25 units with full in-process inspection. ASTM B117 on exterior and corrosion-critical finishing. COC on pilot shipment.
Production Release
Volume production with documented inspection intervals. PMI and dimensional sampling per quality plan. Batch traceability and COC on every delivery.

Quality Documentation — Standard on Every Program

Every RV OEM and van conversion program ships with the complete documentation stack that production programs require for warranty defense and incoming inspection efficiency.

Document
What It Confirms
Mill Test Reports (MTRs)
Chemical composition and mechanical properties of raw material, heat-traceable to the parts ordered
PMI / XRF Analysis
Elemental composition of actual fabricated parts — confirms the alloy specified was the alloy used, using our Olympus XRF analyzer
First Article Inspection (FAI)
100% drawing callout inspection, material confirmation, finish verification, and load test on structural hardware — signed by qualified inspector before production release
Certificate of Conformance (COC)
Shipment-level conformance declaration on every delivery — enables lot release without 100% physical inspection
ASTM B117 Salt Spray Reports
Accelerated corrosion test documentation on exterior and high-exposure hardware — finish performance confirmed before production release
Dimensional Inspection Records
Actual measured values on production sampling — allows trend tracking across shipments

Finishing Options

We apply the same finishing processes to RV and van conversion hardware that we run for marine OEM programs — with ASTM B117 corrosion testing available to verify performance before production release. Finish specification is matched to the application environment, not applied from a catalog default.

  • Anodizing — Type II and Type III hardcoat for aluminum exterior and structural components
  • Powder coating (PPG) — specified to application environment with documented surface prep and conversion coat protocol
  • Passivation — ASTM A967 for stainless exterior and structural hardware
  • Electropolishing — maximum corrosion resistance for high-cycle stainless applications
  • Brushed, polished, and bead blast mechanical finishes for aesthetic hardware
RV & Van Conversion Fabrication Resource Library
We've published a five-part technical series covering metal hardware specification and fabrication for RV OEM manufacturers and van conversion programs — including weight optimization frameworks, custom versus off-the-shelf decision criteria, exterior hardware specifications, corrosion protection standards, and supply chain risk controls.

Working with a Single Partner Across All Hardware Categories
Most RV OEM manufacturers and van conversion upfitters manage 8–12 separate metal hardware vendors across exterior, interior, and chassis categories. Consolidating stainless and aluminum hardware with a single qualified OEM fabrication partner reduces qualification overhead, enforces consistent material and corrosion standards across every category, and creates one point of accountability for everything metal on the vehicle — from roof rack systems and exterior structural hardware to interior mounting systems, chassis brackets, and kitted assembly programs. Programs typically start with one hardware category and expand from there.
