Exporting Profiles – Standardization

Global Roofing Profile Compliance & Engineering Guide

Exporting roofing profiles is not simply shipping steel sheets.

It requires:

• ✔ Dimensional standard alignment
• ✔ Local code compliance
• ✔ Structural validation
• ✔ Coating certification
• ✔ Documentation accuracy
• ✔ Machine compatibility

Many exporters fail because they:

Assume one profile fits all markets.

It does not.

Standardization is the foundation of successful global profile distribution.

1️⃣ Why Standardization Matters

Each region has:

• Different effective cover widths
• Different naming systems
• Different structural expectations
• Different corrosion classifications
• Different fire codes

A 36" PBR panel from the USA:

Is not directly compatible with a 1000 mm European trapezoidal profile.

Standardization reduces:

• Custom redesign
• Production errors
• Coil mismatch
• Installation conflicts

2️⃣ Metric vs Imperial Differences

USA:

Uses inches and gauge.

Example:
36" cover, 26 gauge.

Europe & Asia:

Use millimeters.

Example:
1000 mm cover, 0.5 mm thickness.

Exporting requires:

Clear dimensional conversion — not rounding.

36" ≠ 1000 mm.

Misalignment causes installation issues.

3️⃣ Effective Cover Width Differences

Common covers globally:

• USA → 36" (914 mm)
• EU → 1000 mm
• China → 840 mm
• UK → 1000 mm
• South Africa → 686 mm (IBR)

Profile width must match regional demand.

Export success depends on regional standard alignment.

4️⃣ Rib Height Standardization

Common naming systems:

• Europe → 35/1000
• UK → 32/1000
• USA → PBR (approx. 1.25" rib)
• China → 25-840

Exporters must:

Match local height expectations.

Changing rib height changes:

• Structural performance
• Span capability
• Market acceptance

5️⃣ Steel Grade Standard Differences

USA:
ASTM standards

Europe:
EN 10346 (S350GD, S450GD)

Japan:
JIS standards

India:
IS standards

China:
GB/T standards

Grade naming differs, but yield strength must be equivalent.

Documentation must clearly state:

MPa yield strength, not just grade code.

6️⃣ Coating Standards Across Regions

Common global coatings:

• Z275 (EU)
• G90 (USA equivalent)
• AZ150 (Al-Zn)

However:

Coating mass measurement units differ.

USA uses oz/ft²
Europe uses g/m²

Improper conversion causes compliance rejection.

7️⃣ Corrosion Class Differences

Europe uses:

C1–C5 corrosion categories.

Coastal Middle East may require:

Higher coating mass than inland Europe.

Export specification must match:

Local exposure environment.

8️⃣ Fire & Wind Certification

Export markets may require:

• ✔ Class A fire rating
• ✔ FM approval
• ✔ UL uplift rating
• ✔ CE marking
• ✔ UKCA marking

Profile alone is insufficient.

System testing may be required.

9️⃣ Structural Load Calculations

Snow and wind loads vary by country.

• USA uses ASCE standards.
• Europe uses Eurocodes.
• Australia uses AS/NZS standards.

Exporting requires:

Span tables adjusted to local code.

🔟 Fastener Compatibility

Profile export must include:

• Correct fastener type
• Correct washer diameter
• Correct corrosion rating

Fastener mismatch is a common export failure.

1️⃣1️⃣ Coil Width & Developed Width Standardization

If exporting machines:

Machine must match:

Local coil supply width.

Example:

European mills commonly supply 1250 mm coil.

Chinese mills often supply 1000 mm, 1200 mm, or 1250 mm.

Profile design must align with available coil widths.

1️⃣2️⃣ Documentation Requirements

Successful exporting requires:

• ✔ Material test certificates (MTC)
• ✔ Coating mass certification
• ✔ Fire test documentation
• ✔ Structural span tables
• ✔ Installation manual
• ✔ Declaration of Performance (EU)

Without documentation, shipment may be rejected.

1️⃣3️⃣ Language & Labeling

Many regions require:

Local language installation manuals.

Incorrect labeling can delay customs clearance.

Standardization includes documentation translation.

1️⃣4️⃣ Common Export Mistakes

• ❌ Converting inches incorrectly
• ❌ Ignoring local wind load
• ❌ Using insufficient coating
• ❌ Sending wrong fasteners
• ❌ Failing to provide certification
• ❌ Assuming one profile works globally

Each region must be engineered specifically.

1️⃣5️⃣ Standardized Global Profile Strategy

Some manufacturers develop:

Global core profiles.

Example strategy:

• ✔ 1000 mm trapezoidal (global)
• ✔ 35–40 mm rib height
• ✔ Adjustable gauge range
• ✔ Multiple coating options

Then adapt minor details per region.

This improves manufacturing efficiency.

1️⃣6️⃣ Machine Export Standardization

If exporting roll forming machines:

Machine must support:

• ✔ Local voltage & frequency
• ✔ Local safety standards
• ✔ Target profile geometry
• ✔ Required gauge range
• ✔ Coating compatibility

Machine CE/UL compliance may be required.

1️⃣7️⃣ Regional Profile Examples

• USA → PBR, R-panel
• EU → 35/1000, 45/1000
• UK → 32/1000
• Africa → IBR
• China → 840 profile
• Middle East → 40–45 mm trapezoidal

Export success depends on aligning with local dominant profile.

1️⃣8️⃣ Engineering Summary

Exporting profiles requires:

• ✔ Dimensional standard alignment
• ✔ Structural code compliance
• ✔ Coating mass verification
• ✔ Documentation completeness
• ✔ Fastener compatibility
• ✔ Machine capability

Standardization is not simplification.

It is controlled adaptation to global requirements.

FAQ Section

Can one roofing profile be sold globally?

Not without dimensional and compliance adjustments.

Is 36" equal to 1000 mm?

No — 36" is 914 mm.

Do coating standards differ by country?

Yes — units and minimum requirements vary.

Does exporting require fire certification?

Often yes, depending on project type.

Can machines be exported without modification?

Usually voltage and safety compliance must be adapted.

What is the biggest export mistake?

Assuming local standards match your home market.
