CE Retrofit Guide for Imported Roll Forming Machines

How to Make a Non-CE Roll Forming Machine Compliant in the European Market

Many roll forming machines imported into Europe — especially from Asia, the Middle East, or older U.S. builds — arrive without valid CE conformity.

Common issues include:

No formal risk assessment
Missing or incomplete Technical File
Guards that are cosmetic, not compliant
No safety-rated control circuit
No Declaration of Conformity
Incorrect or invalid CE marking

If you operate in the EU or place machinery on the EU market, compliance with the Machinery Directive 2006/42/EC (transitioning to the EU Machinery Regulation 2023/1230) is mandatory.

This guide explains — step by step — how to retrofit an imported roll forming machine to achieve CE compliance.

Understand What CE Compliance Actually Means

CE marking is not a sticker.

It means:

A formal risk assessment has been completed
Hazards have been eliminated or reduced
Safety control systems meet required performance levels
Technical documentation exists
A Declaration of Conformity has been issued

For roll forming machines, the key harmonised standards usually referenced include:

EN ISO 12100 – Risk assessment
EN 60204-1 – Electrical safety
EN ISO 13849-1 – Safety-related control systems
EN ISO 14120 – Guard design
EN ISO 13850 – Emergency stop

Retrofitting must align with these principles.

Step One: Conduct a Formal Risk Assessment

Before modifying anything, perform a documented risk assessment per EN ISO 12100.

Identify hazards in all phases:

Installation
Setup
Threading
Production
Cleaning
Maintenance
Decommissioning

Typical roll forming hazards:

In-running nip points
Shear blade access
Punch amputation risk
Hydraulic pressure hazards
Electrical exposure
Unexpected restart
Coil recoil

For each hazard:

Determine severity
Determine probability
Apply hierarchy of control
Record risk reduction measures

Without a written risk assessment, CE compliance cannot be demonstrated.

Guarding Upgrades (Physical Risk Reduction)

Most imported machines fail CE on guarding.

Common problems:

Reach-through gaps
No interlocked access
Exposed chain drives
No shaft end caps
Guards removable without tools

CE Retrofit Guarding Requirements

☐ Fixed guards secured with tools
☐ No finger reach-through per EN ISO 14120
☐ Enclosed roll stands
☐ Fully enclosed chain drives
☐ Guarding extended to prevent reach-over
☐ Interlocked doors where access required

Mesh opening size must prevent access to hazard.

Upgrade Safety Control Architecture

Many imported machines rely on:

Standard PLC only
Single-channel E-stop wiring
No safety relay
No monitoring

Under EN ISO 13849-1, safety functions must meet a defined Performance Level (PL).

Retrofit Requirements

☐ Install safety relay or safety PLC
☐ Dual-channel emergency stop
☐ Guard interlock monitoring
☐ Fault detection capability
☐ Manual reset required
☐ Safe restart logic

Emergency stops must comply with EN ISO 13850.

Shear & Punch Compliance

Open shear access is a common CE failure.

Required Retrofit Actions

☐ Fully enclosed shear housing
☐ Interlocked access door
☐ Mechanical blade blocking for maintenance
☐ Punch enclosure
☐ Interlocked punch access

No hazardous movement may occur with guard open.

Electrical Panel Compliance (EN 60204-1)

Imported panels often fail electrical inspection.

Common issues:

No lockable main isolator
No PE (earth) marking
Incorrect conductor sizing
No proper documentation
Mixed voltage labeling

Retrofit Checklist

☐ Install lockable main isolator
☐ Verify protective earth continuity
☐ Label circuits
☐ Provide electrical schematics
☐ Ensure correct short-circuit protection
☐ Mark emergency stop circuit clearly

Electrical conformity is one of the most inspected areas during CE audits.

Hydraulic & Pneumatic Safety

Hydraulic systems must be assessed for:

Hose rupture
Stored pressure
Uncontrolled cylinder movement

Required Measures

☐ Pressure relief valves
☐ Lockable isolation valves
☐ Pressure discharge procedure
☐ Hose inspection program
☐ Shielding for exposed hoses

Stored energy must be controlled during maintenance.

Lockout / Energy Isolation Procedure

CE requires safe maintenance capability.

You must provide:

☐ Written isolation procedure
☐ Clearly labeled isolation points
☐ Lockable disconnect
☐ Hydraulic isolation
☐ Pneumatic isolation (if applicable)
☐ Verification of zero energy

Emergency stop is not sufficient.

Create the Technical File

To CE mark a machine, a Technical File must exist.

It typically includes:

Risk assessment
Electrical schematics
Hydraulic schematics
Safety circuit diagrams
Guarding drawings
Performance Level calculations
Instruction manual
Maintenance instructions
Declaration of Conformity

The file must be retained for 10 years.

Issue the Declaration of Conformity

After retrofit and validation:

Confirm compliance with Machinery Directive
Reference applicable harmonised standards
Sign Declaration of Conformity
Affix CE marking plate
Provide instruction manual in local language

The company placing the machine on the EU market becomes legally responsible.

Common CE Retrofit Failures

1️⃣ Guarding looks compliant but still reachable
2️⃣ No PL calculation for safety circuit
3️⃣ E-stop not safety-rated
4️⃣ No documented risk assessment
5️⃣ Incomplete technical file
6️⃣ No instruction manual
7️⃣ No performance validation

Auditors focus heavily on documentation consistency.

1️⃣2️⃣ When a Notified Body Is Required

Most roll forming machines do NOT require a Notified Body.

However, complex automated systems may require additional review under certain categories.

Always verify scope.

Cost Considerations

Typical retrofit costs:

Guard fabrication: moderate
Safety relay upgrade: moderate
Full safety PLC: higher
Electrical panel corrections: moderate
Risk assessment & documentation: professional service cost

Non-compliance can result in:

Machinery seizure
Fines
Insurance issues
Civil liability

Retrofit Priority Order

If budget is limited:

1️⃣ Guard shear & punch
2️⃣ Install safety relay
3️⃣ Implement LOTO
4️⃣ Fix electrical isolation
5️⃣ Document risk assessment
6️⃣ Complete technical file

Engineering risk reduction first.

Final CE Compliance Checklist

☐ Risk assessment completed
☐ Guards compliant
☐ Safety-rated control circuit
☐ Interlocked access
☐ Electrical panel compliant
☐ Hydraulic isolation
☐ LOTO documented
☐ Technical File complete
☐ Declaration of Conformity signed
☐ CE plate affixed

If any are missing, the machine is not legally compliant.

Frequently Asked Questions

Can I CE mark a used imported machine myself?

Yes, but you become legally responsible as the “manufacturer” placing it on the EU market.

Is CE the same as OSHA?

No. OSHA is U.S. enforcement. CE is EU conformity marking.

Do I need a safety PLC?

Not always — but safety functions must meet required Performance Level.

How long must Technical File be kept?

10 years from machine placement on market.

Can cosmetic guards pass inspection?

No. Guards must physically prevent access.

Final Summary

To retrofit an imported roll forming machine for CE compliance, you must:

Perform a formal risk assessment
Upgrade guarding
Install safety-rated control architecture
Implement proper energy isolation
Correct electrical compliance issues
Create complete documentation
Issue Declaration of Conformity

CE compliance is legal responsibility — not optional marketing.
