SummaryHaosail demonstrates broad equipment-related business scope, documented quality and service procedures, ISO9001:2015 certification, four production lines, and 50 quality-control staff. It offers extensive customization, ODM and OEM services, reports new products within the past year, and has two years of total R&D engineer experience stated. Overseas support includes warehouses, showrooms, agents or branches, installation, debugging, maintenance, repair, and training. Export sales account for 90%, with stated lead times within 15 workdays in both peak and off-season. Financial records are indicated for 2022–2024, but no financial figures or performance evidence are provided. Customer cases and specific customer references are not supplied.

Supplier typeThe stated business scope includes sales of mechanical equipment, metal chains and other metal products, marine aquaculture equipment, pumps and vacuum equipment, automotive spare parts, and electronic products. This supports classification as a diversified equipment and industrial-products supplier, but the slice does not identify a narrower legal or manufacturing category.

CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit evidence of a quality management system certification, although the provided information does not include the certificate body, validity period, or scope.

After-Sales capabilityThe supplier reports written and followed procedures for complaint handling, corrective and preventive actions, and service capability assessment. It also states that overseas warehouses, showrooms, agents or branches, and services including installation, debugging, maintenance, repair, and training are available; stated service lead time is within 15 workdays in both peak and off-season.

R&D capabilityThe supplier reports new products within the past year, ODM capability, an available SDK, ERP-based digital management, and ongoing enterprise digitalization. These statements support active R&D and digital-transformation capability, although the limited stated total R&D engineer experience of two years prevents a stronger assessment of technical depth.

Production capacityThe supplier reports four production lines, 50 quality-control staff, multiple machines covering heading, wrapping, heat treatment, netting, welding, and dynamometer testing, and uniformly followed finished-product inspection instructions. It also reports qualified service suppliers, overseas service resources, and lead times within 15 workdays, providing explicit evidence of operational capacity.

Product Q&A

Q:What is a snap hook used for?

Snap hook is a universal rigging hardware used for quick connection, chain assembly, rope linking, cargo lashing, marine docking, lifting equipment and outdoor safety fixation. It is widely applied in industrial rigging, construction, marine, transportation and fall protection systems.

Q:What standards do your snap hooks comply with?

Our snap hooks strictly comply with DIN5299 A/B/C/D standard. Some heavy-duty models meet industrial lifting requirements and support CE certification, ISO9001 quality system and WLL load marking standards.

Q:What are the materials of your snap hooks?

We have three main materials: carbon steel, 304 stainless steel and 316 stainless steel. Carbon steel is for general industrial use; 304 and 316 stainless steel are anti-rust and suitable for marine and outdoor environments.

Q:What is the difference between DIN5299C and DIN5299D snap hook?

DIN5299C is a standard spring snap hook without locking nut for quick connection. DIN5299D is a safety locking snap hook equipped with screw lock nut to prevent accidental opening, much safer for heavy load lifting.
