Greenhouse Accessory Duckbill Card Is A Specialized Fastener Used To Fix The Connection Points Of The Greenhouse Skeleton. It Is Named After Its Resemblance To A Duckbill And Plays A Role In Quickly Locking The Skeleton And Enhancing Structural Stability During Greenhouse Construction.
High Strength Cold-rolled Steel Plates Are Commonly Used As Materials, Which Have Excellent Rust Resistance After Galvanizing Treatment And Can Resist The Erosion Of High Humidity Environments Inside The Shed. The Service Life Can Reach 5-8 Years. Some Products Are Made Of Stainless Steel Material (304 Model), Which Has Stronger Corrosion Resistance And Is Suitable For Coastal Saline Alkali Areas Or High-temperature And High Humidity Planting Sheds.
The Structural Design Is Clever, Consisting Of A Fixed Base And A Movable "duckbill", Which Is Elastically Clamped Through Spring Plates. The Opening Of The Bayonet Can Be Adjusted (usually 10mm-30mm), Which Can Adapt To Different Specifications Of Round And Square Tube Skeletons. The Clamping Force Can Reach Over 500N, Effectively Preventing The Skeleton From Loosening Under Wind Loads.
Installation Is Extremely Convenient, With No Need For Tools To Manually Press And Lock. When Disassembling, Simply Pull The Release Tab At The Tail Of The Duckbill, And The Performance Is Stable After Repeated Use. In Greenhouse Construction, It Is Mainly Used For The Cross Connection Of Arch Bars And Longitudinal Bars, And The Fixation Of Side Columns And Crossbeams, Especially Suitable For The Rapid Assembly Of Prefabricated Greenhouses, Which Can Shorten The Working Hours Of Traditional Bolt Connections By 60%.
Compared To Wire Binding Or Bolt Fixing, Duckbill Clips Do Not Damage The Surface Coating Of The Skeleton, And Can Buffer The Thermal Expansion And Contraction Stress Caused By Temperature Changes In The Skeleton, Reducing The Risk Of Structural Deformation. They Are An Efficient And Reliable Connecting Accessory In Modern Greenhouse Construction.
