AI-Powered supplier vetting
SummarySUZHOU SHUNCHI HARDWARE CO., LTD. is identified as a China-based trading company established in 2018, with 10 employees and a 125.0 m² manufacturing plant. Its offerings focus on garage doors, industrial doors, hardware systems, high-speed doors, and loading dock equipment. The supplier claims continuous product innovation, technical support, quality focus, and on-time delivery. Reported operational data includes four production lines, 6–10 quality-control staff, substantial component output, and an export-sales share of 71%–90%; however, some records identify the business as CHI Hardware, creating a naming inconsistency. No certification information or detailed after-sales processes are provided. One buyer, RIVER CITY DOORS LTD, is listed, and imports from the US and shipments from Pusan are recorded.
Supplier typeThe supplier is explicitly classified as a Trading Company and Limited Company, based in Suzhou, Jiangsu, China. Its stated product range covers garage doors, industrial doors, hardware systems, high-speed doors, and loading dock equipment, while the listed manufacturing plant and production data indicate some operational production capability as well.
R&D capabilityThe company explicitly claims continuous product innovation and states that it designs newer and more precise products to meet customer requirements. This is direct evidence of an innovation focus, although no patents, development team details, or independently verified innovation results are supplied.
Production capacityThe supplier reports a 125.0 m² manufacturing plant, four production lines, 6–10 quality-control staff, and annual outputs of 2,000,000 roller shutter accessories and 10,000,000 garage door components. These figures provide explicit evidence of production activity and capacity, despite the supplier also being classified as a trading company.
Client casesRIVER CITY DOORS LTD is listed as a buyer associated with the supplier, and the records indicate imports to the US. This is one identifiable buyer reference, but the information does not provide order details, product scope, duration of cooperation, performance evidence, or multiple verified customer cases.
Product Q&A
Q:What information do I need to provide to get the correct torsion spring?
A:
Please send us: door width, door height, door weight (or panel count and
material), track type (standard lift, high lift, or vertical lift), and your
required cycle life rating. We will calculate the correct wire diameter, inside
diameter, spring length, and winding direction and return a full specification
within 24 hours.
Q:What is the difference between 10,000-cycle and high-cycle torsion springs?
A:
The cycle rating indicates how many open-close cycles a spring is designed
to perform before failure. Standard 10,000-cycle springs meet the residential
baseline. 25,000-cycle and 50,000-cycle springs use heavier wire gauge and
tighter tolerances - recommended for commercial doors, automatic systems with
high daily usage, or buyers offering extended warranties to their customers.
Q:Do you supply matched pairs for double-spring systems?
A:
Yes. For heavier doors (typically 16ft width and above, or doors over 200 lbs),
a two-spring system is required. We supply matched left-wind and right-wind pairs
with identical spring rates to ensure balanced door travel.
Q:What surface treatment options are available?
A:
Standard finish is oil-tempered or zinc-phosphate coating. For buyers in coastal,
high-humidity, or cold-climate markets (such as Canada, Russia, or coastal USA),
we recommend our galvanized coating option for extended corrosion resistance.
Q:Are your springs compatible with EZ-SET or other tool-assisted winding systems?
A:
Yes. We offer EZ-SET compatible winding cones as an option. Standard winding
cones are pre-drilled for conventional winding bars. Please specify your preference
when ordering.
