It reports ISO 9001 and ISO 14001 certification, seven production lines, 6–10 R&D engineers, and 6–10 quality-control staff. The supplier states that it provides 24/7 international-sales coverage, responses within 24 hours, quality-complaint attention, and 100% product inspection. Its export activity began in 2020, with 21%–30% of sales reportedly from exports. Evidence is insufficient to assess financial credibility, customization capability, or innovation capability. One buyer name and one trade transaction are listed, but this is limited evidence for customer-case strength.
Supplier typeThe supplier is described as a Manufacturer/Factory and Group Corporation, with a Jiangsu factory location and a subsidiary role in the parent group’s international sales and distribution activities. Its stated products include electric heating trace products and flood-protection systems.
CertificationsThe supplier reports holding ISO 9001 and ISO 14001 management-system certifications. These explicitly support quality-management and environmental-management capability, although no certificate details or validity dates are provided.
After-Sales capabilityThe supplier states that its international sales team provides service 24 hours a day, 7 days a week, responds to customer demands within 24 hours, and gives priority attention to quality complaints. It also claims 100% product inspection, directly supporting a stated after-sales and quality-response process.

These explicit capacity and operational details indicate established production capability.
Product Q&A
Q:Is the flood barrier permanent?
A:
The demountable flood barrier is mobile; only the end post is pre-installed. Central posts and panels are removable for storage. However, once deployed, it provides permanent flood resistance.
Q:How do I choose between demountable and freestanding barriers?
A:
Demountable barriers offer better water tightness and leave minimal visual intrusion when removed. Freestanding barriers are fully removable but generally offer less water tightness, mainly for water division.
Q:What is the material of the flood barrier?
A:
Mainly aluminum extrusion profiles (6063/6005 series) with argon arc welding. It includes EPDM/PE gaskets, stainless steel anchors, and bolts. Freestanding versions use ABS plastic.
Q:Is the mobile flood wall heavy to operate?
A:
Metal barriers are made of lightweight aluminum, making them easy for a single adult to operate. Glass walls are heavier and may require a crane for large panes.
Q:What is the maximum flood protection height?
A:
Demountable barriers can be produced from 200mm to 4600mm, adjustable in 200mm increments. Glass walls are fixed at design (400-1500mm) but can be extended with extra beams.
