Common quality issues and solutions?

Hollows or Detachment: Caused by an unclean base or uneven adhesive. Reinforce small areas with injected adhesive; cut out and relarge large areas. Surface Cracking: Caused by improper curing or lack of expansion joints. Fill fine cracks with elastic sealant; cut open wide cracks and fill with anti-crack mortar. Moisture Damage: Caused by poor sealing leading to water seepage. Re-seal with glue; replace if severely damp.

Specifications and Eco-friendliness?

Specs: Standard width is usually 600mm, thickness ranges from 10mm to 100mm (20mm or 30mm is common for underfloor heating). Eco-friendliness: Prefer virgin material boards (low VOC) and avoid inferior recycled materials (which may contain free benzene).

AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and ODM capabilities, reports new product development within the past year, and operates two production lines with stated inventory capability. It has written procedures and records for supplier-service assessment, corrective and preventive actions, and customer complaints. Management-system certifications include ISO9001:2015, ISO45001:2018, and ISO14001. Reported delivery lead times are within 15 working days in both peak and off-season, with access to Guangzhou, Foshan, and Shenzhen ports. However, the supplier began exporting only one year ago, has no valid manufacturing-capacity contract with related subcontractors, and lacks overseas warehouse and showroom capabilities. No collaboration with Fortune 500 companies is reported. The available financial information is incomplete and inconsistent in detail, so financial credibility cannot be conclusively assessed.

Supplier typeThe supplier is presented as a manufacturer with a technical team, hundreds of production and sales personnel, two production lines, and in-stock capability. However, it reports no valid contract with related subcontractors, so the precise manufacturing structure and capacity governance are not fully established.

CertificationsThe supplier explicitly reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. Product compliance certification and raw-material quality reporting are listed only as “Others,” without specific certification names.

After-Sales capabilityWritten procedures and followed records are reported for service-capability assessment, corrective and preventive actions, and customer complaints. Service terms include multiple quotation and payment options, while stated peak- and off-season lead times are within 15 working days; overseas warehouse and showroom services are unavailable.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, and a technical team developed through continuous improvement. These statements provide explicit evidence of product-development capability.

Production capacityThe supplier reports two production lines, inventory capability, and lead times within 15 working days in both peak and off-season, with access to three nearby ports. However, it has no valid contract governing manufacturing capacity with related subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full customization, minor customization, and flexible customization. It also provides ODM services, indicating broad support for customer-specific product development.

Client casesThe supplier explicitly reports no collaboration with Fortune 500 companies. No other named customer cases or verified customer references are provided in the slices.

Product Q&A

Q:What is an XPS board? Where is it used?

XPS (Extruded Polystyrene) board is a rigid thermal insulation board with a closed-cell structure. It is mainly used for thermal insulation of exterior walls and roofs, moisture protection for underfloor heating and basements, as well as engineering protection for highways and other projects.

Q:What are the core advantages?

Strong Insulation: Extremely low thermal conductivity with excellent heat retention. High Compression Resistance: Resistant to deformation under long-term pressure. Excellent Waterproofing: Almost zero water absorption, highly moisture-resistant. Long Lifespan: Dimensionally stable and resistant to both high and low temperatures.

Q:How to quickly tell good quality from bad?

Look: Uniform color (light yellow/blue/grey) with a fine, pore-free cross-section. Press: High hardness, good rebound when pressed, and does not collapse. Burn: Self-extinguishes when removed from fire, with little smoke and no pungent odor.

Q:How to choose the fire rating?

You must choose B1 (Difficult to burn) or B2 (Combustible) grade. The use of B3 (Flammable) grade or uncertified "three-no" products is strictly prohibited.

Q:Key points for installation?

The base layer must be flat and clean; boards should be laid with staggered joints; board seams must be tightly sealed; and finished product protection should be applied promptly after laying.
