Greenhouse Top Clamp

As a standardized agricultural supply accessory produced by a source-level industrial and trade integrated manufacturer, the Greenhouse top clamp manufactured by YS STEEL is compatible with most circular greenhouse arch tubes available on the market. It can be purchased in bulk at any time and can also be customized for the inner diameter of the steel tube, the diameter of the spring, and the number of coils according to the outer diameter of the steel tube, providing a long-term wind-resistant roof fastening solution for overseas greenhouse engineering contractors, planting bases, and agricultural supply traders.

Core Technical Parameters

Key selling points

1. Persistent rebound without relaxation

2. Flexible selection of dual anti-corrosion processes

3. High precision of CNC coiling spring

4. Quick manual installation and disassembly

Performance upgrade items

1.Fatigue resistance enhancement adjustment.

For the long-term wind vibration conditions of open-air greenhouses, the spring has undergone pre-fatigue release treatment to reduce the problem of loosening and failure caused by long-term high-frequency vibration.

2.Edge rounded and blunting process.

All spring cutting positions are polished and blunted to eliminate sharp edges, eliminating the risk of cutting the plastic film and injuring the hands of construction workers at the source.

3.Coating full coverage protection upgrade.

PVC impregnation ensures the complete 360° wrapping of the steel wire, eliminating the possibility of exposed steel wire breaks； the hot-dip galvanized version adds a post-treatment sealing process to further delay the generation of white rust.

4.Batch consistency control upgrade.

Each coil of spring steel wire is inspected for mechanical tensile force before storage. Products of the same batch have a very small elasticity deviation, ensuring the uniform clamping force of tens of thousands of spring clamps, suitable for large-scale greenhouse project construction.

Usage precautions

1. When selecting, prioritize verifying the "actual outer diameter" of the arch tube. Do not purchase based solely on the theoretical specifications of the greenhouse； a deviation in pipe diameter size will cause the spring to be too loose and slip or too tight and difficult to install.

2. For coastal salt spray and saline-alkali areas, the PVC impregnated version should be preferred. The hot-dip galvanized version is more suitable for dry inland farmland environments.

3. Spring clamps are elastic consumables. It is recommended to randomly check the clamping status of each spring before the onset of the strong wind season； replace them in time if there is rust or a significant decrease in elasticity.

4. Do not forcibly pry the spring beyond the range to expand it； excessive stretching will cause permanent deformation of the spring and irreversible attenuation of the clamping force.

5. When storing accessories, it is recommended to place them in a dry and ventilated warehouse. For outdoor stacking, make sure to cover them with rain protection and shading to prevent premature rusting and loss.

FAQ

Q1: What are the long-term advantages of using the greenhouse top clamp compared to ordinary cable ties?

A: It is a reusable and detachable elastic accessory. Unlike plastic cable ties, it won't deteriorate or break due to sun exposure. When replacing the plastic film later, there is no need to cut it all off.

Q2: How do the two anti-corrosion versions select the type based on the local climate?

A: For inland ordinary farmland, hot-dip galvanized products are available; for areas with salt spray, high humidity, and saline-alkali soil conditions, PVC impregnated spring clips are recommended.

Q3: The arch pipe has a non-standard special diameter. Can you provide custom spring clips?

A: We support customized production. You only need to provide a sample of the steel pipe's outer diameter or precise drawing parameters, and we will arrange the production accordingly.

Q4: For large-scale overseas greenhouse projects, what supporting services can you offer?

A: We can provide factory inspection reports, customized export packaging, complete customs clearance documents, and also offer long-term stable annual framework supply.

Q5: Besides fixing the plastic film, what other materials can the spring clips press down?

A: It can be paired with shading nets and insect-proof nets. It is only recommended for flexible mesh and film-like materials and is not suitable for fixed on hard plates.

Q6: How to reduce the probability of spring clips loosening and falling off later?

A: Select the matching pipe diameter specification and prohibit excessive stretching; conduct regular inspections after the windy season and replace the elastic components that have lost elasticity in a timely manner.

Q7: Can we get a sample before placing the order to test the elasticity and compatibility with the steel pipe?

A: We offer sample delivery service. You can test the clamping effect on-site and then finalize the bulk order.
