Load-tested custom spring components
Custom Vibration Isolation Springs That Match Load, Deflection and Approval Requirements
For spring mount, HVAC isolator and building isolation projects, XULONG SPRING helps buyers move from drawing or sample to verified springs with clear specifications, surface finish and inspection records.
Identify the sourcing risk
Wrong load range, finish or documentation can delay mount assembly approval.
Match the application
Select spring mount, HVAC, hanger, floating floor or building isolation use cases.
Verify before production
Samples, load test records and material documents support engineering approval.
Send RFQ parameters
Submit drawing, load, deflection, finish and quantity for a focused quotation.
Application fit
Match the spring to the isolation application before quoting
Different isolation products need different load ranges, colours, finishes and packaging. Start with the actual assembly or project use case, then confirm the spring specification.
Spring Mount Components
Open, housed and restrained mount spring components for OEM mount suppliers.
HVAC Isolator Springs
Springs for fans, pumps, chillers, cooling towers, AHUs and mechanical rooms.
Isolation Hanger Springs
Spring components for suspended pipework, ductwork and ceiling-mounted equipment.
Building Isolation Springs
Heavy-duty compression springs for structural and acoustic isolation projects.
Colour-Coded Series
Painted spring ranges for load identification and private-label assemblies.
Custom Project Springs
Manufactured from drawings, physical samples or load and deflection requirements.
Production proof
Evidence that makes repeat orders easier to approve
Once the application is clear, buyers need confidence that the supplier can repeat dimensions, load performance, colour marking and export packing. This section shows the proof points behind that decision.
0.1-80mm Range
Strong capacity in 5-80mm heavy-duty springs.
Quality Documents
Material, inspection and load test reports available.
Surface Treatment
Painting, zinc plating, electrophoresis and anti-rust options.
Export Packing
Carton, pallet or wooden case packing support.
Technical confidence
Turn drawings, samples or load data into verified spring specifications
A reliable quote starts with clear parameters. Send drawings or sample photos when available; we can support verification documents for engineering and purchasing approval.
Load Test Support
Working load, deflection and inspection records available when required.
Sample Policy
5 pcs free samples per item for qualified projects, typical sample lead time around 14 days.
Cooperation fit
For OEMs, contractors and engineering buyers who need stable supply
This page is positioned for spring mount manufacturers, HVAC isolation suppliers, acoustic contractors and project buyers who need stable custom spring components.
OEM Supply
Private-label spring series and repeatable batch production for mount assemblies.
Project Support
Specification review and documents for building, acoustic and HVAC projects.
Export Cooperation
