Most buyers receive wildly different quotes for the same roll forming machine — not because suppliers are dishonest, but because the request for quotation (RFQ) they sent was incomplete, ambiguous, or open to interpretation. When a supplier can interpret your requirements loosely, they will quote a machine that meets their standard offering rather than your actual needs.
This guide gives you the RFQ structure and specific questions that will get you accurate, comparable quotes — and that will immediately reveal suppliers who cannot meet your requirements.
Why Roll Forming Machine RFQs Go Wrong
A typical buyer's RFQ says something like:
"We need a cable tray roll forming machine for producing trays 200–600 mm wide, 1.0–2.5 mm thick, galvanized steel."
This gives the supplier almost no useful information. They do not know:
- What profile geometry (what shape is the sidewall, what is the base perforation pattern?)
- What production speed you need (and whether you mean rated or actual)
- What cut length tolerance is required
- What PLC brand and interface language you need
- Whether CE marking or other certification is required
- What your local power supply is (380V/50Hz? 415V/60Hz?)
- What your after-sales support requirement is
- When you need delivery
Without this information, every supplier quotes their standard configuration. The lowest quote is always the one that assumed the most favorable interpretation of every ambiguity.
The 8-Section Roll Forming Machine RFQ Template
Section 1: Product Specification (The Profile)
This is the most important section. Include:
- Profile drawing with all critical dimensions labeled (width, height, flange length, sidewall angle, corner radii)
- Material: type (galvanized steel, stainless, aluminum), grade (Q235B, Q345B, 304SS, 6061 aluminum), and coating specification
- Material thickness range: minimum, maximum, and most common
- Cross-section sketch or DXF file — if you can, include a physical sample
Why it matters: Suppliers size the machine frame, drive power, and roll station count based on the profile geometry and material. Without this, every specification is a guess.
Section 2: Production Requirements
- Target production speed (meters per minute, actual not rated)
- Target daily output (meters per shift, shifts per day)
- Cut length range and tolerance (e.g., 3–6 m, ±1 mm)
- Punch pattern if required (hole size, hole pitch, pattern drawing)
Section 3: Automation and Control
- PLC brand preference (Mitsubishi, Siemens, Delta, etc.)
- Operator interface: touchscreen HMI, language requirement
- Recipe storage: how many product variants does the machine need to store?
- Remote access: is remote PLC diagnostics required?
- Level of automation: manual coil loading vs. auto-feeding vs. full turnkey?
Section 4: Electrical Standards
- Local power supply: voltage, frequency, phase
- Electrical safety standard: CE (EU), UL (US), or local equivalent
- Motor protection standard: IP55 or IP65?
Section 5: Physical Constraints
- Available floor area (length × width, minimum aisle clearances)
- Available headroom (for coil crane loading)
- Foundation specification: existing concrete floor rating, or new foundation to be designed
Section 6: Certification and Documentation
- Product certification required (CE, AASHTO, etc.)
- Machine certification required (CE Machinery Directive, UL, etc.)
- Documentation language requirement
- Spare parts list requirement
Section 7: Commercial Terms
- Required delivery location (port of discharge or factory address)
- Target delivery date
- Payment terms (LC, T/T, etc.)
- Incoterms preference (FOB, CIF, DDP)
Section 8: Supplier Qualification Questions
These questions separate serious suppliers from catalogue sellers:
- Can you provide a video of a machine producing this exact profile at the quoted production speed?
- What is the steel grade and hardness specification of your roll tooling?
- What is the warranted dimensional tolerance on the critical profile dimensions?
- Who is the PLC and servo system supplier? Provide the model numbers.
- What is the standard warranty period and what is excluded?
- Can you provide references from customers producing the same or similar profile?
- What is your installation and commissioning process for overseas orders?
- What spare parts do you recommend purchasing with the machine, and what is their current lead time?
Reading the Quotes: Red Flags and Green Flags
Green flags in a supplier response:
- Direct answer to every Section 8 question, with video evidence and specific technical commitments
- Proactive questions about your profile and production requirements before quoting
- References to specific customers they can introduce
- A clear statement of what is and is not included in the quoted price
Red flags:
- Generic brochure sent in response to a specific RFQ
- Refusal to name the PLC or servo brands until "order is confirmed"
- No video evidence of the machine running your profile
- Price significantly below all other quotes (usually means something is missing)
- Warranty limited to "components not caused by operator error" — a clause that enables them to reject almost any claim
