Agricultural Tarpaulins buying guide

Quick answers

What is the best tarpaulin for covering hay?

A large heavy duty polyethylene sheet of 200gsm or more. It is waterproof and comes in sizes big enough for a full stack. Rope it down well so wind cannot get under it.

Should I use canvas or plastic to cover farm machinery?

Polyethylene and PVC are fully waterproof. Canvas is water-resistant and breathes, so less condensation forms underneath. Canvas suits metal stored for months under some shelter.

What size are your largest farm tarpaulins?

The 200gsm sheet goes up to 35m x 20m. The 250gsm sheet goes up to 22m x 25m and the Monoflex Leno sheet up to 16m x 32m.

Are agricultural tarpaulins UV resistant?

Most of our polyethylene sheets are UV-stabilised to slow sun damage. Check the product page for the sheet you choose.

How do I stop a tarpaulin blowing off a stack?

Use every eyelet, run rope over the top of the stack and weigh down the edges. Check the fixings after strong wind.
