Q1: Can you provide samples?

A: We provide roofing sheet samples free of charge, with the customer covering the shipping cost. Please let us know which product you need so we can confirm sample availability and shipping arrangements.

Q2: Do you support product customization?

A: Pingyun offers customization discussions. Share your required product type, length, width, thickness and color so we can confirm which options are available for the selected model.

Q3: How long is the delivery time?

A: Production lead time depends on the model, quantity and customization. Your quotation should state when the lead-time period begins and distinguish the estimated production schedule from shipping time. We will confirm the schedule for your specific order before it is placed.

Q4: How are payment terms confirmed?

A: Available payment methods, the payment schedule and the terms for your order will be confirmed in the quotation.

Q5: Can you ship to my country?

A: Share your destination and the products you need. We will confirm the available shipping arrangements and required order documents. We do not assume that every product has the same destination requirements.

Q6: How can I check product quality?

A: Ask for the current specifications and available inspection information for the exact product you are ordering. Confirm the material, profile, dimensions and acceptance requirements before production or shipment.

Q7: How will the products be packaged for shipment?

A: Packaging should be confirmed for the product, order quantity and shipping route. Please ask for the proposed packing method and handling requirements when requesting a quotation.

Q8: What roofing products does Pingyun offer?

A: Pingyun’s product range includes PVC roof tiles, corrugated UPVC roof sheets, hollow PVC roof sheets, translucent roof sheets, and polycarbonate sheets. Tell us your application so we can help identify the product category to discuss.

Q9: How do hollow PVC roof sheets differ from corrugated UPVC roof sheets?

A: Hollow PVC roof sheets have internal cavities, while corrugated UPVC roof sheets are identified by their external wave or trapezoidal profile. These are different product families, and the exact cross-section, effective cover width, fixing method and thermal performance depend on the selected model. Share your roof drawing and requirements so we can compare the current product specifications.

Q10: Do you offer roofing sheets that allow daylight through?

A: Yes. Pingyun lists PVC translucent roof sheets and FRP transparent roof sheets, as well as polycarbonate sheet categories. Tell us the daylighting area, preferred material and the roof profile to be matched; we will confirm the current specification and installation details for the proposed model.

Q11: What is the difference between wave and trapezoidal UPVC roof sheets?

A: They have different profile shapes. Before choosing one, check your roof design, support layout and required cover width. Do not assume the two profiles use the same laps or fixing details.

Q12: Are Spanish and Roma PVC roof tiles the same product?

A: Pingyun lists Spanish and Roma roof tiles as separate categories. Check the exact profiles and accessories before treating them as interchangeable.

Q13: Can a new roof sheet be matched to my existing roof?

A: Please provide the existing sheet’s profile drawing, measurements and clear photos. We can compare them with the proposed product, but final compatibility—including laps, fixings and support details—must be confirmed for the existing roof before ordering.

Q14: Do all Pingyun UPVC roof sheets have an ASA surface?

A: Do not assume so. Material construction can vary by product. If an ASA surface is required, specify it in your inquiry and ask us to confirm the construction of the exact sheet offered.

Q15: Are Pingyun roofing sheets suitable for corrosive environments?

A: Some Pingyun PVC/UPVC roofing products are marketed for corrosion-resistant applications, but suitability cannot be assumed for every sheet or exposure. Please provide the chemicals or other substances involved, their concentration and temperature, and details of fixings and supports. We can then review the current information for the exact proposed product; the project designer should verify the complete roof assembly.

Q16: Do you offer gutters and downspouts?

A: Pingyun lists PVC gutters and downspouts as a product category. Please contact us to confirm current availability, dimensions and compatibility with your roofing product.

Q17: How do I estimate the number of roof sheets I need?

A: Provide the roof plan, slope dimensions and the selected sheet profile. Quantity should be calculated using the exact product’s effective cover width, required overlaps and roof details—not its overall sheet width alone.

Q18: Can I use the same installation method for every roof sheet?

A: No. Fixing, support and overlap details depend on the material and profile. Request the installation guidance for the exact product and have the final roof design checked against local project requirements.

Q19: How should I maintain PVC roofing sheets?

A: Inspect the roof periodically for damaged sheets, loose fixings, blocked drainage and debris. Use cleaning methods suitable for the selected product, and avoid assuming the sheets are safe to walk on.

Q20: Does an advertised product lifespan equal a warranty?

A: No. A lifespan stated on a product page is not the same as the written warranty for your order. Ask for the warranty terms covering the exact product, including the period, exclusions and claim procedure.

Q21: Do hollow PVC roof sheets provide thermal insulation?

A: Pingyun lists twinwall hollow PVC roof sheets. The hollow structure may contribute to thermal resistance, but the performance of a finished roof depends on the exact sheet and installed assembly. Ask for product-specific thermal data before specifying it for insulation.

Q22: Will PVC roof sheets reduce rain noise?

A: Acoustic results depend on the sheet and the complete roof assembly. If noise reduction matters to your project, request evidence for the proposed product and installation method.

Q23: What fire-performance information should I request?

A: Ask for the current fire-test documents applicable to the exact product and your market. A general claim on a product page should not be treated as evidence that every sheet meets the same requirement.

Q24: Can the sheets be used in areas with strong wind or heavy snow?

A: Provide the project location, roof layout, support details and applicable design loads. A qualified project designer should verify the proposed sheet, supports and fixing arrangement against local requirements, using product-specific information supplied for the exact model.

Q25: Does temperature change affect roof-sheet installation?

A: Temperature changes can cause roof sheets and adjacent components to move. Allowances for movement should follow the selected product’s installation guidance and the project design; do not copy a fixing detail from another sheet type.

Q26: Is there one minimum roof slope for all Pingyun sheets?

A: No single slope should be assumed for the entire range. The appropriate slope depends on the profile, overlaps, roof details and project conditions. Confirm it for the exact product before installation.

Q27: How should roof sheets be stored before installation?

A: Keep the sheets protected from damage and follow the storage instructions for the selected product. Confirm stacking, covering and handling requirements before the shipment arrives on site.

Q28: What should I do if sheets arrive damaged?

A: Record the condition of the packaging and sheets on arrival, take photographs, and keep the product labels and shipping documents. Report the issue promptly under the terms agreed for your order before installing the affected sheets.

Q29: Can roof sheets from different production batches look different?

A: Appearance should be checked against the approved sample and order requirements. For a roof where a consistent finish matters, discuss batch identification and the acceptance criteria before ordering.

Q30: What should be checked before replacing only part of a roof?

A: Compare the replacement sheet with the existing roof’s material, profile, dimensions, color and fixing details. Also check the condition of the surrounding roof; a sheet that looks similar may not fit the existing assembly.
