Span Review Input Checklist
Span review depends on project conditions. Send available information before requesting a panel recommendation.
- Project country and location
- Wall or roof application
- Building height
- Support spacing
- Design wind pressure
- Snow load where applicable
- Panel thickness
- Steel facing thickness
- Core material
- Required fire and thermal performance
PE / HDP / PVDF Coating Selection
PE Coating
Commonly reviewed for general industrial and commercial building projects where standard coated steel facing is suitable.
HDP Coating
Reviewed when stronger weathering performance is requested for outdoor envelope applications.
PVDF Coating
Reviewed for demanding exterior exposure projects where premium coating performance is required by the specification.
Coating Environment Checklist
- Distance from coastline
- Humidity
- UV exposure
- Industrial pollution
- Required design life
- Indoor or outdoor use
- Cleaning or chemical exposure
Final coating selection should be confirmed against project environment, steel facing specification, color requirement and available supplier documentation.
Drawing Review Workflow
Submit drawings and specifications
Send plans, elevations, sections, panel schedules, sketches and available specifications.
Review panel application
Identify whether the project requires wall, roof, cold room, clean room or accessory support.
Discuss wall, roof and core options
Review suitable panel system options according to project application and document needs.
Confirm thickness, facing and coating
Confirm requested panel thickness, steel facing, coating type and color requirements.
Review accessories and packing
Coordinate flashings, fasteners, sealants, packing method and export loading requirements.
Prepare technical and commercial quotation
Prepare quotation support based on confirmed scope, product selection and document requests.
Drawing review supports product selection and quotation preparation. It does not replace structural design or approval by the project’s licensed engineer.

Engineering FAQ
Can LIAOHE review architectural or shop drawings?
Yes. LIAOHE can review drawings for product selection, quotation preparation and document coordination. The review does not replace project engineering approval.
Are wall and roof joints different?
Yes. Wall joints, roof laps, ridge details, eave conditions and opening trims should be reviewed separately for the selected system.
How should panels be selected for coastal projects?
Coastal projects should review coating type, distance from coastline, humidity, salt exposure, fasteners, sealants and maintenance requirements.
Can flashings, fasteners and accessories be supplied together?
Yes, accessories can be coordinated with the panel package when drawings and quantity requirements are provided.
Does LIAOHE provide structural engineering approval?
No. Product and quotation support does not replace structural design or approval by the project’s licensed engineer.
Are BIM files available?
BIM files are not published as default downloads. If a project needs BIM-related support, request the available document scope for review.
Request Engineering Support and Quotation
Send your drawings, panel schedule or project requirement. LIAOHE will review the available documents and quotation inputs for the selected sandwich panel system.
