AI-Powered supplier vetting

SummaryBeijing IWHR Corporation is identified as a China-based state-owned manufacturer/factory and group corporation, with 148 employees and valid import-export licensing. It provides extensive customization, has introduced new products within the past year, and offers an SDK, indicating established development capabilities. ISO 9001 and ISO 14001 certifications, 50 quality-control staff, and documented procedures for supplier assessment, corrective actions, and complaint handling support its quality-management and service processes. The supplier has exported for 30 years and reports that exports represent 41%–50% of total sales. However, it reports no inventory capacity, overseas warehouse, overseas showroom, or ODM service, while environmental assessment, fire-drill status, and trade-volume information are unspecified. No explicit customer cases are provided.

Supplier typeThe supplier is described as a manufacturer/factory and group corporation, with a separate entry also identifying it as a trading company. It is a state-owned limited company based in Beijing, China, with 148 employees and valid import-export licensing; the mixed classification should be clarified during due diligence.

CertificationsThe supplier holds ISO 9001 and ISO 14001 certifications. These explicitly support quality-management and environmental-management system credentials.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints, as well as corrective and preventive actions, and it can provide services through overseas agents or branches. However, it lacks overseas warehouses and showrooms, so its after-sales infrastructure is documented but not comprehensive.

R&D capabilityThe supplier reports new products within the past year, has an available SDK, and has 21–30 years of total R&D-engineer experience. Its described activities also include R&D and system integration, providing explicit evidence of substantial innovation resources.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These repeated listings demonstrate broad customization coverage, although ODM service and OEM service for popular brands are not provided.

Product Q&A

Q:How does the hydraulic elevator dam operate?

The back side is supported by two hydraulic cylinders powered by a hydraulic station. Lifting time is about 1min/m, and lowering time is adjustable from 30s to 30min. It can achieve arbitrary dam height for water retention.

Q:How does the dam handle sedimentation on its surface?

It is designed to withstand severe mud and sand sedimentation. The dam can adjust to a vertical angle of 75 degrees to wash away sedimentation under normal flow conditions.

Q:What should be done if branches and stones are stuck in the dam?

Floating objects like branches will drift away with water flow. For stones stuck between surfaces, adjusting the dam's angle allows stones to be released due to gravity and water flow.

Q:Is it possible to lift and drop the dam at the same time?

Yes, by custom designing the hydraulic pump station to achieve synchronous lifting and dropping. Enhanced flow and power may increase the cost.

Q:What is the maximum span of the rubber dam?

Rubber dams can have spans as long as 100 meters without dividing piers, providing full width of the active cross-section for flood flow release.
