There are several materials we use for grain covers with the TX-1200 as the most common. It is a 3-ply laminate combining two layers of linear low density polyethylene and a high-strength cord grid. It is specifically engineered to provide high strength and durability in a lightweight material.

Grain stockpiles and grain bunkering are becoming very common in agriculture as a less expensive alternative to silos. You can now store wheat, barley, corn, soybeans, rice, nuts, cottonseed and other various commodities on a large scale.
Unlike long term structures like silos which are costly to erect and move, temporary grain covers are quick to deploy and are a fraction of the cost.
Some of the factors that we consider when selecting the cover material are: chemical compatibility, UV stability, puncture strength, durability and installation method. Another consideration is the length of time the cover is needed. For temporarily needs we will recommend a thin film material such as 6 mil thickness. For long term cover needs we might recommend a 15 or 23 mil thickness.
We offer a wide range of materials which are suitable for both short term and long term applications including polyethylene, polypropylene and PVC. Each of these materials offer unique characteristics in terms of weight, tear strength and UV resistance.
The covers are supplied in panels and can be installed by the customer in the field. The covers can be sewn, taped or even welded together by the user.
There are several methods to anchor your cover. For smaller stockpiles you can use heavy objects around the bottom perimeter to hold down the cover. For larger stockpiles it is common to use sandbags in a grid formation to hold the cover in place. ALCO can supply the sandbags for your project if needed.
Yes. If there is damage to your stockpile cover, then it can be repaired in the field using field patch tape. You can purchase the tape from ALCO and get your cover back in working order quickly.
