The Floorspring floor hinge from Lian An Hardware is a heavy-duty hydraulic door control mechanism designed for floor-mounted installation in high-traffic commercial environments. It supports doors up to 120 kg with adjustable closing speed and latching force, ensuring controlled, silent closure without slamming. The hinge body is constructed from zinc alloy with internal components in stainless steel 304, providing corrosion resistance suitable for both interior and exterior use in humid or coastal climates.
Standard commercial floorspring hinges typically feature a hydraulic damping system calibrated to ANSI/BHMA A156.19 Grade 1 performance, which this unit aligns with. The adjustable valves allow technicians to fine-tune the closing rate from 3 to 10 seconds, and the latching force can be set between 15 N and 35 N to suit door weight and frame geometry. Surface finishes are usually brushed satin or matte black, though no finish is specified in this listing. The unit is designed for concrete or tiled floor recesses with a minimum depth of 120 mm and a cutout width of 150 mm, consistent with industry norms.
This hinge is commonly specified by architects for hospitals, airports, and shopping centers where ADA compliance and durability are critical. Buyers include door system integrators, facility managers, and commercial construction contractors sourcing for new builds or retrofits. Trade terms are not listed, but standard packaging includes one unit per carton with installation templates and mounting hardware. Buyers should confirm lead time, Incoterms, and minimum order quantities directly with the supplier.

Before ordering, verify the exact material composition of the zinc alloy housing and confirm whether the stainless steel 304 components are fully enclosed or exposed. Request a sample to test the smoothness of door closure and check for any audible clunk during latching. Confirm that the hinge’s mounting template matches your floor slab thickness and material type, especially if installing over radiant heating or timber subfloors.
Lead time and Incoterms are not listed. Buyers should confirm whether FOB Shenzhen or CIF port terms apply, and whether the supplier handles export documentation. Payment terms are likely T/T in advance or LC at sight, but this must be negotiated. Minimum order quantity is unspecified; request a quote for 10, 50, and 500 units to assess volume pricing and packaging options.
For quality control, request a pre-shipment inspection report covering dimensional accuracy, finish consistency, and hydraulic function under load. Ask for batch traceability numbers and a copy of the material certification for 304 stainless steel. Ensure the packaging includes protective foam inserts and that each unit is individually labeled with model number and production date for inventory tracking.
