Grain Protection

Grain Protection

Grain bunker covers and ground sheets are a very economical method for temporary on-farm grain storage. Polytex have the capacity to produce large numbers of grain storage covers promptly, arrange for quick transportation Australia-wide as well as supplying specialist equipment required for the grain storage industry.

Polytex has been supplying farmers and grain handlers high strength grain bunker tarps and grounds sheets since the 1990’s and have a reputation for a quality product and personal service.

Grain tarps are used for temporary grain storage on farms or grain handling sites. They are designed to prevent damage from moisture, pests, and other environmental factors while also providing a sealed environment for fumigation. They are also commonly used to cover and protect stored crops, such as canola, almonds, corn, soybeans and many more. They are typically made from durable materials such as polyethylene, polypropylene or polyvinyl canvas (PVC). 

Grain tarps are important for protecting crops because they provide a physical barrier between the crops and the environment. This can help to prevent damage from moisture, pests, and other factors that can reduce the quality and quantity of stored crops. Properly stored crops can lead to higher profits and a more successful farming season. 

Grain tarps can be used to protect a wide variety of crops, including grains, almonds, corn, soybeans, and other commodities. Different types of tarps may be recommended depending on the specific crop and storage conditions. 

Using grain tarps for crop protection can provide several benefits, including: 

  • Preventing moisture damage and mould growth 
  • Protecting against pests and rodents 
  • Reducing the risk of heat damage 
  • Minimizing losses due to spoilage 
  • Maintaining crop quality and quantity 

When selecting a grain tarp, there are several features to consider, including: 

  • Material quality and durability 
  • Customizable options, such as colour to reduce glare 
  • Size and coverage area 
  • UV protection 
  • Ability to withstand extreme weather conditions 
  • Proper anchoring and tie-down options 

Proper installation and maintenance are key to ensuring the effectiveness of grain tarps. Tarps should be securely anchored and tied down to prevent wind damage, and proper ventilation should be provided to prevent mould growth. Regular inspections and maintenance, such as cleaning and repair, should also be performed to prolong the lifespan of the tarp. It is important to follow the manufacturer’s recommendations for installation and maintenance to ensure the best results. 

The lifespan of grain tarps depends on several factors, such as the material used, storage conditions, and frequency of use. Polyethylene tarps, which are commonly used for grain storage, typically have a lifespan of 2-3 years if stored and used properly. However, Polytex’s grain tarps are designed to be durable and long-lasting, and with proper care and maintenance, they can last for many seasons.
