What is Wiggle Wires for Greenhouse Construction and Film Fastening

Wiggle wire is a type of fastening system commonly used to secure poly film (such as greenhouse plastic) to frames or structures. It is also named as Polylock spring, zigzag wire, greenhouse spring wire etc. It consists of a wire that is “wiggled” into a channel, often made of aluminum or steel, to hold the plastic film in place. The process works by sliding the wire into the channel, which then compresses the poly film against the frame, creating a tight seal.

This system is highly valued for its durability, ease of use, and ability to withstand wind and weather. It allows for easy replacement of the poly film without needing to remove the entire frame or structure. It’s widely used in agricultural applications like greenhouses or high tunnels.

Plastic wiggle wires defination   

Greenhouse plastic wiggle wire refers to the same fastening system used for securing poly film, but with a plastic coating on the wire. The plastic coating provides additional protection, making the wire more flexible and reducing the risk of damaging the poly film. It is also called as plastic coated spring, plastic coated zigzag etc.

The process still involves the “wiggling” of the wire into a channel, usually made of aluminum, to hold the plastic film tightly against the frame. The plastic coating helps to prevent rust and corrosion, which is especially important in outdoor or agricultural settings where the system is exposed to moisture and weather conditions.

In short, plastic wiggle wires offer the same function as traditional metal wiggle wires but with enhanced durability and a gentler grip on the film.

How many types of wiggle wires in the market?  

There are typically two main types of greenhouse wiggle wires:

1. Standard Metal Wiggle Wire

• Material: Made of galvanized steel or stainless steel or other alloy steel.
• Function: This is the most common type, known for its strength and durability. It is used in channels to secure poly film or other plastic coverings to greenhouse frames or other structures.
• Pros: High strength, long-lasting, and can handle heavy weather conditions.
• Cons: The metal can rust over time, especially in wet environments.

2. Plastic-Coated Wiggle Wire

• Material: Made of the same steel core as the standard metal wire but coated with a layer of plastic (usually powder coated PE).
• Function: This wire also goes into the channels to secure the poly film, but the plastic coating provides additional flexibility and prevents damage to the film.
• Pros: Reduces friction, less chance of film damage, and rust-resistant, can protect valuable plastic film. High strength spring wire, can be repeated use for film fastening. UV stablized coating can extend wiggle wire life up to 6 years.

Plastic coated wiggle wire was original from Japan, and OEM manufactured by Beijing Fenglong Greenhouse Technology from China, right now Beijing Fenglong is the largest producer of plastic coated wiggle wire ( Zigzag ) in the world, and carry out most restrict quality control system to make sure the qualified product supplying. Right now Beijing fenglong is the largest plastic coated wiggle wire supplier in the world, has capacity to produce 50 millions pcs each year.

Other Variations:

• Different sizes: Wiggle wires can come in different diameters or lengths depending on the thickness of the poly film being used and the size of the frame channels. Mostly in 2 meter length and 2.0mm thick wire, or 2.3mm thick wire.
• Wire coatings: Some manufacturers may use other types of coatings besides vinyl, like a rubberized or powder-coated finish, for specific conditions.

So, in terms of types, the primary distinction is between standard metal and plastic-coated, with variations in size and specific coatings for different environmental conditions.
