AI-Powered supplier vetting

SummaryShanghai Languan New Building Materials Co., Ltd. is described as a developer, manufacturer, and seller of environmentally friendly building decoration materials. Its stated scope covers building materials, floor-related solutions, machinery and equipment, hardware, chemical products, communication equipment, and import/export and technical services. The supplier reports OEM service for well-known brands, quality assurance, documented complaint-handling and corrective-action procedures, and facilities including mixing, self-leveling, and automatic packaging lines. However, it has no available SDK, no stated AI-based decision-management practice, no inventory capability, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial information is limited to years identified as 2021–2023 without performance values. Certification, customer cases, and detailed customization evidence are not sufficiently documented.

Supplier typeThe supplier is presented as Shanghai Languan New Building Materials Co., Ltd., focused on R&D, production, and sales of environmentally friendly building decoration materials. Its business scope includes building materials, insulation materials, sealing fillers, cement products, machinery, hardware, chemical products, and related sales and import/export activities, supporting classification as a building-material manufacturer and supplier.

After-Sales capabilityThe supplier reports clear procedures and records for corrective and preventive actions and customer complaint handling, and describes providing technical guidance and comprehensive customer services. However, it lacks overseas warehouse and showroom capabilities, so the evidence supports structured service handling but not broad overseas after-sales infrastructure.

R&D capabilityThe company describes R&D activity and the ability to develop new materials using existing technology, and its culture emphasizes innovation. However, it explicitly has no available SDK and has not established an AI model for big-data decision support; these limitations prevent a broad conclusion that its innovation capability exceeds requirements.

Production capacityThe supplier states that it conducts production and lists processing and manufacturing activities, with a mixing line, self-leveling production line, and automatic packaging robot. Quality assurance and documented corrective-action procedures are also reported, although there is no valid contract with affiliated subcontractors and no in-stock capability.

Customization capabilityThe supplier reports OEM services for well-known brands and says it provides solutions for difficult floors, technical guidance, and development of various new materials using existing technology. This directly supports some customization and OEM capability, although the slices do not specify product scope, minimum quantities, lead times, or engineering resources.

Product Q&A

Q:Can LG670 be applied directly over old tiles without removal?

Yes. LG670 is designed for old tile renovation. Apply 1-2 coats over cleaned old tile surfaces. After tack-free, self-leveling compound or tile adhesive can be applied. However, hollow tiles must be checked and repaired first to ensure a solid substrate.

Q:What is the coverage rate of LG670?

About 0.1-0.15 kg/m2 per coat, depending on substrate smoothness. Use lower values for smooth tile surfaces, higher for slightly rough surfaces. Usually 1 coat is sufficient; for very smooth surfaces, 2 coats are recommended. One 20KG bucket covers approximately 130-200 m2 (1 coat).

Q:Is LG670 compatible with all types of self-leveling compounds?

LG670 is compatible with cement-based self-leveling compounds (K26, K50, K80, K90, etc.), gypsum-based self-leveling, epoxy floor coatings, polyurethane flooring, and tile adhesives. For first-time use with a new product model, a small-area test is recommended.

Q:Can LG670 be used on waterproof membranes?

The time before covering is approximately 24 to 48 hours.

Q:Is customization available for this product?

Yes, we offer full customization, minor customization, and options from samples or designs.
