Answer: The core protective performances are reflected in two aspects:

1. Waterproof grade reaches IP68, enabling leak-proof operation and normal lifting/lowering even after 48 hours of water immersion, making it adaptable to outdoor rainy and waterlogged environments;
2. Anti-collision grade reaches K12, capable of normal use after being hit by a 12-ton vehicle and only deforming after impact by a 16-ton vehicle, with strong protective capabilities.

It is suitable for high-security demand scenarios including: government agencies, public security/procuratorate/court units, transportation hubs such as airports/railway stations, bank vault entrances, main entrances of large commercial complexes, etc. It can effectively prevent malicious vehicle ramming and enhance regional anti-terrorism and security protection levels.

Answer: ① High customization flexibility: Supports multi-dimensional customization, including material thickness (default 6mm, modifiable), diameter (default 219mm, modifiable), raised height (600-1100mm optional), as well as free logo, packaging, and graphic customization (minimum order quantity ≥10 units). It can also adjust the hydraulic system and control functions as needed;

② Low order threshold: Single-unit orders are accepted, no bulk purchase required, enabling cooperation with small and medium-sized customers;

③ Short delivery cycle: The lead time for regular orders (1-100 units) is only 7 days, and for orders exceeding 100 units, it is negotiable. It can quickly respond to urgent project needs, and the transportation method can be selected as required (air freight for urgent orders/seafreight for cost reduction).

Answer: Quality control measures include:

1. Complete certifications (CE, RoHS, ISO9001) that comply with international standards;
2. ERP system for procurement cost control and ISO9002 standards for process regulation in production;
3. Uninterrupted fatigue testing at the testing stage (ensuring a service life of 3 million cycles), pre-shipment inspection, and support for third-party supervision to eliminate defective products.

Core concerns of overseas customers that can be addressed:

1. Quality worries — Multiple certifications and full-process testing ensure product reliability;
2. Installation difficulties — Provision of installation guide videos and real-time video call technical support, no on-site dispatching required;
3. Communication efficiency — Response time ≤3 hours and full follow-up by sales teams to resolve time zone and language communication issues;
4. Customization assurance — Video communication available during the design phase to ensure the realization of customization needs.
