At EVS Metal, we’ve been partnering with customers on precision metal fabrication projects for over 30 years. In that time, we’ve learned that one factor consistently predicts project success more than any other: the quality of the initial Request for Quotation (RFQ).
A well-prepared RFQ does more than just solicit bids—it establishes clear expectations, ensures accurate pricing, reduces project delays, and sets the foundation for a successful partnership. Here’s what we’ve learned about creating RFQs that lead to better outcomes for everyone involved.
Why Your RFQ Matters More Than You Think
Let’s be honest: preparing detailed RFQs isn’t anyone’s favorite task. But rather than viewing it as administrative burden, consider this: your RFQ is the blueprint that shapes your entire project. When done right, a thorough RFQ saves time, reduces costs, and establishes productive working relationships from day one.
For guidance on evaluating fabrication partners beyond just the RFQ process, see our complete guide to choosing a metal fabrication partner.
Essential Elements of a Complete Metal Fabrication RFQ
1. Technical Drawings and CAD Files
What to provide:
- Complete technical drawings with all dimensions clearly marked
- CAD files in common formats (STEP, IGES, DXF, DWG, or native SolidWorks/Inventor files)
- 3D models when available (especially helpful for complex assemblies)
- Any referenced standards or specifications
Pro tip: Include both 2D drawings AND 3D files when possible. 2D drawings provide detailed specifications, while 3D models help fabricators quickly assess manufacturability and identify potential issues.
2. Material Specifications
Be specific about:
- Material type (aluminum, stainless steel, carbon steel, etc.)
- Grade or alloy (e.g., 6061-T6 aluminum, 304 stainless steel, 1018 carbon steel)
- Temper or condition
- Acceptable substitutions, if any
Why it matters: Material selection significantly impacts cost, lead time, and performance. If you’re weighing options, our comparisons of welding aluminum vs. steel and ferrous vs. non-ferrous metals can help clarify tradeoffs. If you’re open to alternatives that could reduce cost or improve manufacturability, mention that—but always specify your baseline requirement.
3. Tolerances and Quality Requirements
Critical information:
- General tolerances for the part (e.g., ±0.010″, ±0.005″)
- Critical dimensions requiring tighter tolerances
- Geometric dimensioning and tolerancing (GD&T) callouts where applicable
- Surface finish requirements
- Flatness, perpendicularity, or other geometric specifications
- Inspection requirements (first article inspection, FAI reports, CMM inspection, etc.)
Common mistake to avoid: Don’t specify unnecessarily tight tolerances across the board. Tighter tolerances increase cost and lead time. Call out critical dimensions that truly need precision, and use standard tolerances elsewhere. Consistent inspection and quality control—like those required under ISO 9001:2015 certification—help ensure specifications are met without adding unnecessary cost.
4. Finishing and Secondary Operations
Specify:
- Surface finish requirements (mill finish, brushed, polished, specific Ra values)
- Protective coatings (powder coating, wet paint, anodizing, plating)
- Color specifications (RAL, Pantone, or custom color samples)
- Deburring and edge finishing requirements
- Hardware insertion (PEM nuts, studs, standoffs)
- Assembly requirements, if applicable
- Marking or labeling (part numbers, logos, serialization)
If finishing is part of your specification, start with our overview of metal finishes and applications, or explore the benefits of in-house powder coating for improved durability, quality control, and lead times.
5. Quantity and Volume Information
Include:
- Initial order quantity
- Expected annual volume or recurring orders
- Prototype vs. production run distinction
- Potential for volume increases
- Stocking program interest (Kanban, JIT, consignment)
Why it matters: Fabricators optimize their processes differently for prototype runs (1-10 pieces) versus production runs (100+ pieces). Volume information helps them provide the most cost-effective approach and accurate lead times.
6. Timeline and Delivery Requirements
Clarify:
- When quotes are needed
- Target delivery date or required lead time
- Any critical project milestones
- Shipping destination and preferred carrier
- Packaging requirements (standard, custom crating, export packaging)
- Delivery preferences (dock delivery, liftgate service, inside delivery)
Be realistic: Rush projects are possible but come at a premium. If you have flexibility, mention it—fabricators may offer better pricing for standard lead times.
7. Regulatory and Compliance Requirements
If applicable, specify:
- Industry standards (ASME, ASTM, AWS, MIL-SPEC)
- Certifications needed (ISO, ITAR, AS9100, FDA)
- Material certifications or test reports
- Compliance requirements (REACH, RoHS, conflict minerals)
- Documentation requirements (C of C, material certs, test reports)
If your project involves defense or aerospace applications, understanding ITAR requirements for manufacturers early in the RFQ process can prevent delays and ensure compliance from the start.
8. Additional Context and Preferences
Helpful information:
- Application or end-use of the part
- Budget constraints or target pricing
- Design for manufacturability (DFM) feedback welcome
- Value engineering suggestions welcome
- Assembly or kitting services needed
- Preferred communication methods and key contacts
Our design for manufacturability services help identify cost-saving opportunities before production begins, and these same principles apply when aiming for better yield and lower overall costs.

Working With Your Fabrication Partner
Ask for Examples and Samples
A reputable fabricator should readily provide:
- Examples of similar work they’ve completed
- Case studies or project portfolios in relevant industries
- References from customers with comparable requirements
- Physical samples of specialized processes
If a fabricator can’t provide examples of claimed capabilities, that’s a red flag. Reviewing real-world outcomes—like this onshoring manufacturing case study—can reveal how a partner performs beyond the quote itself.
Welcome Design for Manufacturability (DFM) Feedback
The best fabrication partnerships involve collaboration from the start. Experienced fabricators can often suggest:
- Design modifications that reduce cost without compromising function
- Alternative materials that improve performance or reduce lead time
- Process changes that improve quality or repeatability
- Features that make assembly or integration easier
Be open to these suggestions. Many of these principles are covered in our article on designing products for manufacturing.
Establish Clear Communication
From the beginning, establish:
- Primary point of contact on both sides
- Preferred communication methods
- Expected response times
- How changes or revisions will be handled
- Regular progress updates for longer projects
Frequently Asked Questions
Q: How detailed should my RFQ really be?
A: The more detail, the better. Every piece of information you provide upfront reduces the need for clarification and leads to more accurate quotes.
Q: What if I don’t know some of the specifications yet?
A: Be upfront about what’s flexible or still being determined. Fabricators can often provide budgetary quotes until details are finalized.
Q: Should I include my budget in the RFQ?
A: This is optional but can be helpful when aligning expectations early.
Q: How many fabricators should I send my RFQ to?
A: Typically 3–5 qualified fabricators is a good range.
Q: What file formats should I provide?
A: STEP and IGES files are best for 3D models; PDF is essential for 2D drawings, with DXF or DWG as helpful additions. For deeper guidance, see our overview of sheet metal parts design for fabrication.
