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 roller sizes are available and which track do they fit?
A:
We supply 2" rollers for garage door tracks and 3" rollers for industrial door tracks. The 2" roller runs inside a 2" track and the 3" roller inside a 3" track, guiding the door up and down smoothly. Custom sizes can be developed for special track systems.
Q:Should I choose nylon or steel rollers?
A:
Nylon rollers are the most popular choice - quiet, corrosion-free and smooth on standard residential doors. Steel rollers are stronger and better for heavy-duty or industrial doors. Both materials are available in 2" and 3" sizes. For most residential programs, nylon is the recommended option.
Q:What stem lengths are available?
A:
Standard stem lengths are 4" and 7", with total roller lengths of 119mm and 185mm respectively. The right stem length depends on your door thickness and track-to-door distance. Tell us your door construction and we will confirm the correct size.
Q:What bearing options do you offer?
A:
Three levels: standard 11 steel balls (most universal, supplied in our hardware box), upgraded 13 steel balls with "Precision" marking, and premium 6200ZZ sealed bearing for the smoothest, longest-lasting operation. A dust cover option is available for the precision and 6200ZZ versions to keep the bearing clean in dusty environments.
Q:How many rollers are needed per door set?
A:
As a general rule, one roller per hinge position plus the bottom bracket roller. A standard 8ft 4-panel door uses 12 rollers, and a 16ft 4-panel door uses 14-16 rollers. We provide an exact roller count per door size when you send us your specifications.
